Title: Magazine Reproduction/Image-File Size
Post by: David Eichler on December 23, 2011, 08:44:33 pm
This question is not specific to medium format, but I figure that medium format users will be especially attentive to issues of reproduction quality and delivering large files. With particular regard to full page and double page reproductions in typical magazines, if you deliver a full size AdobeRGB Tiff file, how much of a quality difference will be apparent, compared with, say, an sRGB jpeg? Also, if one delivers an image size moderately smaller than the intended reproduction size, will a small amount of uprezzing really be apparent? This assumes that the images are already otherwise repro-ready and don't need much, if any, additional processing after delivery to the client. Also, are you typically providing hi-res files with output sharpening, or are you leaving that to the printer?

Again, I am talking only about typical magazine reproduction, not display prints or posters. However, could also expand this to good quality, but not top-quality, brochures of comparable size and quality to magazines.

First, what are the publisher's requirements. That will tell you what you need. Each publisher is different.

Why would you send an sRGB JPEG? I would be sending a minimum of an AdobaRGB TIFF or I would be converting it into a CMYK color space for the printer.

Also, what do you mean by reproduction size? These are digital files. They have no size. If you mean an image being 300dpi at page size, then that would be fine unless the publisher request the image to be 600dpi.

If this is a general question, which after getting this far I think it might be, send the publisher the best file you have--do not resize. The DTP folks will know what to do with it. I hope you are shooting RAW and converting to Adobe RGB tiff though. As far as how big an image needs to be to make a good reproduction, a 6MP file or larger would work. It is not a simple question as there are publication and then there are publications. (And some of those publication don't know what they are talking about if your read their submission guildlines, but that is their problem.)

Hey, merry Christmas. ;)

What JPEG compression setting? If the JPEG file has more than enough resolution and is on maximum quality setting, you are unlikely to notice a difference.

My editing workflow is for maximum quality: files from a full frame dslr (21mp), RAW, Prophoto (or Lightroom version of) working color space. Reproduction size: the size of the the printed image. When delivering hi-res jpegs, quality would always be at the highest setting.

Thanks, Graham. From your website it seems evident that you are quite experienced with these matters.

I would not keep your files in JPEG--compression is additive every time you save. The only reason for JPEG is to save file space. Why JPEG? Graham is right that a good JPEG is not a problem, but in a publishing workflow for a designer, it makes no sense.

21MP files should be fine for any application you want, including posters and such. As far as defining an image or reproduction size, I would not waste my time. Unless you are resampling (and you should not be doing that), those numbers are just placeholders and the desktop publishing software will redefine them anyway. You could send me a 21MP file sized to 3"x2" and I can make it any size I want without having to touch your file or the data in your file. Unlike a Photoshop file that have a defined raster size, a page in a magazine can take images of different resolutions and put them together while maintaining the difference. As a designer, I want your best file that has not been resampled.

BTW, sRGB is a web color space and its gamut is smaller than a print space. AdobeRGB is going to preserve your colors better.

Okay, one more bit of info which I see is important and which I left out. I am outputting the files from Lightroom and specifying an image size and resolution, so there is resampling going on. So, let's take a particular case. I outputted some images from Lightroom at 3000 pixels wide and 300ppi, as sRGB jpegs, at maximum jpeg quality, expecting the images to be printed at less than full page (although I had previously seen such a file printed as a full-bleed 8.5 x 11, and it looked fine with average printing in a brochure), with no more than pretty good printing quality. One of these images got printed as a full-bleed, double page spread in a magazine. The result came out very nicely, but I am wondering if the quality of the reproduction could have been even higher. I was not working directly with a printer but with a designer.

By the way, the purpose of the sizing mentioned above is indeed to save file space with less demanding usage, that is: reproductions that will not be full page or greater, print quality that is good but not great, and images that will receive little or no additional processing after I deliver them.

Post by: theguywitha645d on December 24, 2011, 12:28:00 am
David, this seems to be a very broad question and the answer can get a little murky. When I said you should ask the publisher, I was not being flippant, but rather each have different criteria and will use your images differently.

If you are sending this using e-mail, then JPEGs are OK. But if you are uploading them to a server or handing them over, I would have them as TIFF--publishing is a complex workflow and the fewer steps the less chance for a error--I am really think of getting the best out of your work, which is very nice BTW.

There are so many factors in the final results, it is hard to know if it could have been better. But having done this for a long time and speaking as a designer myself, the better the data, the better the outcome. My ideal data from a photographer is a tiff file in AdobeRGB color space that has not been resampled as that will be the sharpest file. AdobeRGB will give me the best chance at getting the color--it will be converted one more time to a CMYK color space and AdobeRGB should fit the printers gamut better than sRGB.

So what happens to an image in a magazine. Layout in a magazine will mostly likely be done in Quark or Adobe InDesign. An image is brought into a layout and is scaled to fit--the designer does not even care about the pixel resolution. When outputting the design to a pdf or native Quark/InDesign file, the application itself fits the image to the layout (Adobe Illustrator and Photoshop are not layout software, although it is possible to make nice single-page documents with them). If the image is about 450dpi or less at a particular size in the layout, the image is printed that way (or at least sent to the RIP that way). If the image is larger than that, the application automatically resamples it.

So, you think if you resize it to the printed page, what is the big deal? First is this is a bleed, I need to make it a little bit larger because of tolerances in the binding process. If the aspect ratio is not quite right for my page, I might have to make it a bit bigger. And finally, if I have an element that is being cut in half by the page edge, I may want to make it a little bit bigger to eliminate that. By the time I have finished, your image can be under 300dpi in the layout. If you give me all your pixels, then I have a good magian for error--we won't even talk about and editor that does not like the left half of your image and wants to crop it out. Or if you plan that the image is for a single page and then the editor wants to change and make it a spread, then I don't have the pixels. Since the application takes care of the resampling automatically, you really don't have to worry about it and the designer is a little freer in using your image. Also the RIP (the software that interpretes the data for the printer) may do the best job of resampling because it understands the printer it is going to.

But printing is only as good as the folks working in the system. A bad designer or printer can screw things up really well. But even the best folks can be limited by the process--the inks, paper, press, costs, etc. Having been on the design side, all I can say is if you give me your best file, I have the best chance at making that look the best.
Title: Re: Magazine Reproduction/Image-File Size
Post by: theguywitha645d on December 24, 2011, 12:39:21 am
David, also some editors set guideline for submissions. There are a bunch that don't understand the process and you get something like "we want color images at 300dpi." Well, a 350x600 pixel file or a 10,000x15,000 pixel file can both be 300dpi--you laugh, but I have had 600x800 pixels files submitted at 300dpi and people not understand why they are not good enough. The editors are not the designers. If you send your best, the designers won't mind (and if they do, run, don't walk, away from that designer).

BTW, web publishing is entirely different from print and resized image may be better--but that is not my area of expertise.

I would add that I only ever send an image as a JPEG if the client specifically asks for it. Otherwise I always use 16-bit RGB TIFFs.

The op speaks of magazine printing. Magazine repro depts Know what to do, believe me. The 1st step theyre gonna do if you send a 16-tiff is: converting it to 8-jpg. Then there is complex editing anyhow in the process of converting to cmyk - dont do it yourself! - and getting it print-ready...

Just send JPEGs at 300 dpi ( full size, ) en 8 bitt in Adobe RGB, ..  -> as there's more than enough quality, an they are not supposed to work on them...
- I do it all the time..

If you send them in sRGB, that can be fine to, but it depents on the magazine and quality of their photogravure... ( or post prod office )

High quality mag's know what they do, so they like sRGB's,
But loads of magazine's have an automized Profile to picture to print system and they are use to get ridiculous quality from bad photographers, so the whole system is calibrated to sRGB, ... 

So it depends, i put the two versions on my server, so they download what they like...

Hi,

There will be very no perceivable difference between a high quality JPEG and an 8-bit TIFF. The difference between sRGB and Adobe RGB is also small, and will probably matter little, as long as color profile is properly handled. Probably, sRGB will be just fine. In addition, sRGB works like a "least common denominator" solution. So if you are not sure that your customer knows what they are doing, send sRGB.

An improperly handled image wil result in color shifts.

Regarding output sharpening it is handled best by the customer. You cannot now the exact parameters the customer will use. Also output sharpening can only be done once exact size of image has been decided. So sharpen you image so it looks good at 1:1 (actual pixels) than zoom out to (1:2) to check if it is oversharpened. Avoid visible haloes at 1:1!

Best regards
Erik


This question is not specific to medium format, but I figure that medium format users will be especially attentive to issues of reproduction quality and delivering large files.

Post by: PdF on December 24, 2011, 08:20:44 am
For my part, I never compromise: I sent Tiff files, Adobe RGB, with the maximum size available. When the recipient asks me specifically, I reduce the file size over the final size print. I NEVER send jpeg to be printed, and I NEVER operates conversion RGB->CMYK. These depend on the types of printing and paper, and remains the responsibility of the printer.

Where possible, I try to go to the printer to check the conversion on a calibrated monitor, and I eventually makes printing to check the "print order".

It's always 16bit , Profoto, Tifs at full resolution. I paid for MF files and that's what they get Period. LOL

I do always send two folders to clients one for the printer specs above than a folder called viewing only with very small jpegs. Those I run a action from the Tifs convert to srgb and make small jpegs. Reason is almost no one has full wide gamut monitors like I have and usually some srgb based monitor for viewing. So my color output will at least look normal for viewing but the printer gets the Profoto specs.

BTW Merry Christmas to the folks here at LuLu from your GetDPI friends.

Post by: David Eichler on December 24, 2011, 03:55:32 pm
Thanks for all the comments. From the above I conclude that sRGB jpegs can be perfectly suitable for the vast majority of cmyk offset printing. Of course, when I deliver files for more varied and more demanding applications, I supply full-size Tiffs without output sharpening, with either the Adobe RGB or Prophoto color space. Not sure why deliver 16-bit rather than 8-bit if there will be no significant additional processing of the images after delivery.

I now understand Russell's comment that a good printer can print just about anything well. In the example I cited above, I was rather surprised that a 3000 pixel wide, 300 ppi, file came out as well as it did for a double page reproduction at typical magazine size, with pretty good paper/printing.

Post by: Craig Lamson on December 24, 2011, 05:38:09 pm
There is no single spec for every magazine, never has been.  In fact very few magazines have identical bleed, trim, live area, same with screen dpi, same with how they ask for delivery.

Honestly, 99.9999999% of this doesn't matter if the image is professional to begin with because a good printer can print from almost anything, a bad printer can't print no matter what you send.

A lot of magazines and clients have moved to jpegs for the obvious reasons of file size and server space . . . oh an also because more of their attention is going to on line and pad distribution than print.

Sending 16 bit for cmyk reproduction is a waste of bandwidth and your client's time.   There is no such thing as 16 bit cmyk and computer/pad viewing doesn't work on the web with 16 bit.

We usually send a variety of images, sized, over sized, tiff with the profile stripped out in rgb (which is usually a generic rgb profile or srgb), rarely adobe 98 as it doesn't covert to cmyk that well and a stand swop cmyk version.

We usually start in colormatch as it bands less under hard imaging and then convert at the end.

But in the end jpegs print just as well as tiffs or psds as no human I've met can look at a jpeg 10 compression and a full tiff and see any difference in final reproduction.

IMO

BC

To show you how the world has changed about 6 years ago we sent guide prints or proofs on every image delivered and our hard printing costs were about $45,000 per year.

Now we rarely turn on a printer, to the point this year a client asked for some prints for the holidays and it took us two days to clean a printer.

Everything we do is delivered ftp and we put an ftp link up ever day.



+1 on colormatch, 8bit deliverables for repro. I've been using it for years and it is bulletproof for cmyk conversions.  I also work at d50 on my NEC.  Pre -press is always quite happy with the files and they require very little intervention.

I virtually only deliver JPG nowadays. Put them on my FTP and the publisher takes them of the ftp server. Since they use their own studio they prefer getting it in Adobe RGB in other cases I take no chances and deliver in sRGB. Printers prefer doing their own conversion to CMYK I have no desire to meddle with that.

I have no printers, I think I can count the number of prints I have done myself this year on 1 hand.

BTW, since PS version 6 saving in compressed JPG does not mean loosing detail more than once (I think it was version 6). Saving over and over does not mean losing quality over and over again (unless you lower the quality when saving).

there are basically 3 sort of output depending on the support.

Adverts displayed on big billboard can have 72 or 150 resolution scaled or not (depends on the size) in 8 bits.
Those are for the pictures that will be inserted in a vector output.
But you don't have to worry about that, it's not your business, you send the file at 300 in RGB or CMYK (only if you know what you're doing and
want to control the output. If not, let the pros optimize the files with more suitable softwares than PS. Just provide a "graded" sample).

Or also 300 in 8 bits  CMYK at generally 1/10 of the final size in big prints. Those are for the non-vector files. It depends on printing techniques,
this one being different than the described in previous paragraph.
If your billboard is 8 meters, the file will be 80cm-300-CMYK in a jpeg or flatten tiff format or PDF, the jpegs have to be prefered for storage-transfer reasons.
Magazines are 300 at 1:1 size in CMYK but RGB are sent all the time specially in newspapers advertizings.

Tiff are used for "in-house" or alpha but not in more than 8bits, it depends on the transfer etc...Prefer the PDF or the JPEG

Designers would prefer to get the max possible file whatever the support is for obvious reasons, but a jpeg is perfectly fine and never in more than 8bits.
So the important is to keep a 300 - 8 bit file except for the web-only in a suitable output.

You may need to send an alpha and depending on the output, a PNG is also an option.

And yeah, a good printer can do wonders with almost anything. But sometimes there aren't always good printers involved and it's not under your control.
Safely and to cover you, it's important to have a good communication, do not hesitate to ask and keep the mails in a folder.
A basic and safe rule is to send a 300 - jpeg or PDF - 8 bits - rgb if no alpha is needed.

Regards.

For images on a billboard, let's say 20 square meter, 35DPi for the image is more than one ever needs. (that is the 1/10 of the real size) Text need to be in vector but the image is printed 35Dpi at max, ( most often way less). 150Dpi is great for an A0 poster in a shop display or a very small bill board. ;D

take a look at page 43 / chapter 2.3 , this will answer all the questions you may have.
according to this there is also the  other normative whitepaper in version 1.1 (already back from 2002) about the workflow norm for printproduction:

http://www.eci.org/lib/exe/fetch.php?id=de%3Adownloads&cache=cache&media=downloads:eci_general_downloads:eci_whitepaper_1_1_eng.pdf

This is a bit harder to read , but this is the normative clamp for the whole european print production, and as I think valid worldwide.

This is the beauty of the Fogra Workflow whitepaper. Responsibilty is given to those who need to take it. You do not have to care about people who are not calibrated.
It´s  not your Business !  See about media neutral workflow.
The hasslefree standard should be either the original file with a camera color space calibration icc tagged
(best! but should be used only if you know that the recipients of your file will handle this correctly!!!! Check it - better double check it and get written approval ! )
2nd best solution is RGB converted to ECI RGB v2.icc (always tagged) as a working space.
NEVER EVER convert to CMYK if not forced to - leave this to the Litho of the dedicated Print house. It´s their job and their responsibilty !
If you do not know exactly what you are doing, which rendering intents to use and how to deal with dedicated custom colors or special needs in the conversion:
KEEP YOUR FINGERS OFF !
And lastly: communicate all these steps to your customer, send them the Whitepaper, tag it to the job if you are unsure and  keep this as a standard.

For me every trip to a new printer is a roll of the dice. I often run into the problem that 16-bit RGB TIFF images I have worked on until they look very fine on my carefully calibrated monitor look for example much too dark or washed out after they have gone through the printers pre-press pipeline that fortunately can often be caught and corrected before the press starts rolling. This is partly a problem of me not knowing WTF I should be doing and partly printers also not knowing what they should be doing, so have found knowing who is doing what to your files can be important and so is communication.

When in doubt I deliver sRGB files that reduces the latitude for the printer to screw up that can happen not only because of lack of professional expertise but also due to the op being overloaded with other work, tight deadlines, the real expert taking a day off, or a lot of other reasons than I cannot think of right now. Same goes for me.

The fact is I've had far less problems supplying clients with digital images than I ever had when supplying transparencies. I'd far rather be responsible for making and supplying the corrected and finalised files than simply handing over a transparency and hoping for the best. Thankfully my clients tend to know their stuff.I'll typically supply unsharpened 16bit 300ppi Adobe RGB Tiff files. The one thing I will never do is convert to CMYK, it's not my job.





True, Keith, but as long as the transparency looked correct on a professional lightbox, the responsibility was that of the next step in the production chain.

The nighmares, for me, were when I was taking a job the whole way through print: then, my own experience in photography simply wasn't enough for me to argue successfully with the friggin' printers who, despite beautiful, client-signed machine proof prints, never equalled that in the actual runs.

Some other guy will always find a way to screw you.

I totally agree. But with experience, I deliver my files in RGB 8 bit, with a "good" sharpening, carried out in FINAL PHASE. The files delivered without sharpening are too often very badly treated by the printers, which use them without any other intervention than transfer in CMYK !!!

I do keep my images in 16bit without any enhancement or sharpening. They then remain fully available for another postproduction process.

Customers grumble when sending the 16bit, very heavy to transmit and manipulate. If there is no more essential intervention, the 8bit seems sufficient to me. Although, in principle, nothing beats a good old 16bit.

It all depends on the magazine you are dealing with. I have had very bad experiences with sending anything other than 8bit sRGB files. sRGB looks at least decent in print if the graphic designer has no clue what she or he are doing, larger color spaces will look washed out unless they have been converted properly. The same goes for 16bit. Granted I have only dealt with small publications, so the bigger magazines might be better with this, but make sure they know what they are doing before you send them anything other than 8bit sRGB files.

Funny aside: I once ftp'ed an Adobe98 16 bit tiff as specified in the magazine guidlines only to get a call from their designer asking me email her a jpeg like everyone else.

This is a song that all the people in the business have sung a lot of years. You are absolutely correct in all what you say.
But the whitepapers have changed something here at least in Germany and as much as I know in most of Europe.
The reason is because of responsibility - and - if something goes wrong and somebody did not comply with the standard
who will have to cover the costs. This works ! The Customer giveth and the Customers takes it - so true - and they sue you !
In case of a large campaign and several hundred of thousands or even millions € of ad costs the word "partial refund" gets a quite different sound
to the agency , the litho or the printhouse which cannot cover their backs in this chain.
This paper is the base for the court to speak who has to pay when all else fails.
Believe me ALL the lithos and printhouses have a quality assurance manager who can pray this paper backwards and forwards like a Muezin sings the Koran.
It´s their Life insurance.

Stefan,

Thanks for the links.

When we deliver to Europe, just like in America or Asia, I find file size, type, etc. to be somewhat all over the place.

Most countries have standards, the AP in London probably had the best and easiest to understand standard, but when it comes to delivery it's all client based.

We rarely get questions about still delivery, though every now and then we have a request that is something like "we want a 350 dpi (ppi) file at 200 inches tall uninterpolated.

We usually say fine, ship a file and let it go.  It prints, people are happy, life goes on.

The biggest issue I find is colorspace.  Almost everyone asks for adobe 98, but have their Photoshop or printer Rips set for something else that assigns a profile and then the images go flat.

Or they view the images in some other proprietary program and nobody knows what the results will look like.

What concerns me most is how the clients preview our images.  Most have their apple monitors set out of the box with somewhere around 2.0 or 2.2 gamma and are very blue.

Though we calibrate everything, (actually spend too much time calibrating everything), I always run an image past a standard bone stock I-mac to get a look at what the client sees and usually adjust for that.

Once it's ready for press, web, pad etc., we give different options.

I still hold by the theory that a jpeg 10 will reproduce as well as any tiff, or psd, but jpeg is somewhat the dirty word in image delivery land.

The same holds true for video.  The standard 90% of our clients request is prorezz 422, though a properly transcoded h264 will perceptually look exactly the same and the file sizes drop to one tenth the size shipping a h264 vs a pro rezz.

A year ago we had a large project that was on an extreme rush with a great deal of processing and post production.  The client wanted layered psds which upped the file sizes dramatically.

The good thing with this client is they were will to go through a series of hard proofs and send them to us so we could adjust colorspace and imagery to match their system.

The downside was we pushed over 500 gigs of final still images through ftp delivery.  At the time it was fast as in our Santa Monica studio we have fiber optics, though lately our connection has been slowing down.

But in the process of this job, delivering images from the retouch team, back to us and back to the client, with rounds of corrections we probably pushed over one and a half to two terabytes of data through the web.

Kinda cool, but somewhat amazing.

The most difficult part is asset management and keeping up with it.  

But in my view the only correct file delivery is what the client requests.

Could it be that once for a while we would end with WW standarts and simplified procedures.

It's completly ironic to see that we are supposed to be in a global economy-exchanges and nothing in this image industry is globalized, standardized (there are zillions of them) and simplified.

Yeah, the wild west...but really really wild!

Unfortunately, even today, when asked for some (many) clients what type of file they want, the answer is often (and only): 300dpi.

That's it!

Sometimes they even know it must be cmyk...... luckely there are good PDF standards for people using pictures in ads and pre-press :-)

Once again, we can read and disseminate all the proper white papers on the planet, but the only real, sure fire way to deliver what a client requests is to deliver what a client requests.

You give them what they want or give them what they need? Big difference...too many photographers try to give clients what the clients think they want only to find out the client doesn't have a clue about what they want.

An educated photographer (maybe somebody who has read a white paper or even written it) will listen carefully to a client and determine for themselves what the client needs. Designers and art directors aren't always the most technically gifted people so you need to have certain knowledge about their needs, not just their wants.

Jeff, some years ago while I was working in an ad agency, they had a big car client for japan wich name I can't reveal. Well, Tokyo would send regularly 72ppp images for printings! We went crazy but had in the end to do it with this material. Designers and printers did wonders. The company couldn't care less about the fact that obviously there was a mistake involved in the chain, if we didn't resolve, we'd loose the contract. Other times it was ok but you never knew what would show-up. Of course, the photographic team that shooted the campaign delivered the files properly, but they go through a lot of different hands in commercial. If people are competent or not it's a bet. They generally are competent but not always. So really, to my experience, being professional in commercial (I insist on this commercial area) is not specially providing the correct or ideal material, wich is important, but much more resolving all sort of issues with whatever material.
And doing it fast. People rarely hire you to educate them, specially the AD wich egos are generally bigger than any dictators in active service and very sensitive if a lack of knowledge would be revealed. like in politics, a great dosis of diplomacy is a plus.

Amazing story. I would think that, for this kind of advertising, maximum resolution and tonal range would be preferred, unless, perhaps, the images were more evocative scenic shots, rather than shots that emphasized the details of the product.  And, how hard can it be to get a major manufacturer to deliver a high-resolution file, unless, perhaps, there simply was no access to a high-resolution file?

It wouldn't be good business not to cover all the bases.

We have a good system that works easily for clients and their respective suppliers.

Each project has a download page with links to various packets such as 1. client requested finals, 2. alternative final images in rgb, cmyk and web use (all sharpened with the final output in mind), with an icon for each packet that downloads through a zip to a folder.

It's really just a touch and download process and what they chose to use or don't is up to them.

I've gone the route of explaining what "I" think is right and once again we do cover the project, but people are going to do what people are going to do.

Actually, it's better to offer alternatives than start shipping pdfs of white pages of "expert" opinion because they rarely go noticed and honestly I've never met more than two clients that required the same exact delivery.

Some of this is because today, unlike a decade ago, a creative group rarely knows exactly where the media will be played.  If it scores well in testing, or is a hit, then it can go from standard print to outdoor, in-store, bus cards, web, magazine print, etc. etc., so that's why we deliver so many variations.

It's better to get the heavy lifting done in the front end than the back and anything is better than allowing a project to become contentious.

I could write a book on some of the requests, mostly from contracted pre press houses and you can respond in two ways, do what they ask, do what you want or actually you can respond in a third way and that is cover all the alternatives.

I chose the third way and keep it positive.

Do you mean that you know exactly what the alternatives will be when you make the delivery? If not, I don't see how you can deliver what you say you deliver: cmyk, output sharpened, Web sized, etc. In my case, I may have to deliver images not knowing exactly the final display size or medium, hence some additional final processing will need to be done by me, or a printer or designer, once the display parameters are determined. Thus the delivery of full-size, non-output sharpened Tiffs.

Always give them what they request.  Its part of your contract (you do have one, right?) with the publication.  But I always give them what I think they need as well.  BC has a slick system with the download page containing links to different formats.  Very smart.  I always gave them what they requested, then FPO 72ppi jpgs US letter sized (which they used for web), then a color corrected TIFF at native file size, 300dpi, RGB.  If they know what they are doing they can use the higher res file.  I've always held firm on not doing CMYK conversions.  I did them for a while, but getting the updated press profiles became more and more difficult.  That is a prepress job.  Prepress will call if they have any questions or need a larger/smaller file, but you know, good prepress is fading. More often than not they use the FPO file, so make sure it looks good.  I only shoot a little for publication now, and I have a client that likes to get prints, then scan them.  Talk about throw back, but I like the process.
