Title: Eye One Photo Profiles with Current Epsons
Post by: ericstaud on December 11, 2006, 06:56:59 pm
Does anyone use the EyeOne Photo setup to create custom profiles for the Epson 2400, 3800, 4000, or 4800?  I am curious about the quality of the results, the need for profiling (whether there is any improvement over canned profiles), and whether the EyeOne setup is as good as services available on the web?

I just don't see many posts about people working with their own print profiling systems.

Most likely due to the cost involved. I would say you are looking at a minimum of $1000 for a decent spectrophotometer based system. I will also say that any package that does not incluse a spectrophotometer is a waste of time (scanner based solutions, etc).

The quality of the iOne profiles is good, especially when compared to the more expensive solutions. If you like to tinker a lot (or do not want to rely on third party profiles or services), then the iOne is the tool for you.

I printed some TC9.18RGB targets on my Epson 3800 today, and am letting them dry overnight. Tomorrow I pan to read them with my GMB i1 Pro and Match 3 software. I see there is a v3.6.1 updater available, so I'll install that as well. I will report back.

Thanks John and Eric,

I have used the Eye1 Photo with my R2400 in the past.  The Heavyweight Matte and Premium Luster profiles I created were nearly identical to the canned profiles.  I think the blacks and grays were slightly more neutral, but without a side by side comparison I would never have noticed.  This means I really used the Eye1 Photo to verify how close my particular R2400 was to Epsons standard, and found out mine is pretty close.  

I am not a big fine art printer.  The only 16x20's framed and hanging on walls that I have made were printed in a darkroom.   With the upcoming purchase of a 3800 I thought I would revisit the issue.  My understanding is that the "Pro" model printers are linearized at the factory.  So custom profiles would likely not be necessary or make very little difference versus the canned Epson profiles when using Epson Media.  It seems the real reason for custom profiling is for the use of third party papers.  Does this kind of thinking generally agree with how everyone else views the issue?

It seems to me that the Eye1 Photo at $1500.00 is the the same as the $250 Eye One + 13-20 custom paper profiles.  Not such a bad deal if you do very much printing or experimenting with papers.

Try the canned profiles from the US first, they are excellent. If you have a lot of papers that are not supported, then it's time to considering building your own if you want to spend the time and money. The quality of the package you mention will do a fine job. You're paying the most for the Spectrophotometer and can upgrade to more robust profiling software in the future if you wish. You can also use the instrument to measure ambient light, strobe, and profile the display, a projector etc.

Many of the more popular third party paper vendors supply profiles on their website at N/C for popular printers (hint-Epson). I have read that some folks have tried the 4800 profiles on their 3800 with good results, but I have not tried that route yet. It souldn't be too long before those paper vendors get those 3800 profiles on their website as that really helps sell the paper.

OK-

Just made some profiles with GMB i1Pro and Match v3.6.1(latest). Targets made for Crane Museo Silver Rag, and InnoveFiba F-Gloss Brilliant White, and dried overnite, and I read them today. Just output some test prints, I need to let them dry a bit, but overall impressions are quite nice. Rich full gamut, nice blacks, the surface is one I have never seen before out of an inkjet printer. Not plasticy, not matte/velvety either. The Museo is warm, as predicted, the Innova is a clean white.

I currently use the EyeOne Photo package for my R2400 and 7800. There are small, but in my mind significant, differences between standard profiles and the ones you make yourself. For paper from  third party vendors the difference can be even more significant. However, you have to be ready to invest a lot of time in learning/testing.

My main complaint about the EyeOne Photo package is the lack of averaging - reading the charts 2-4 times and averaging the measured values to get better data. I do this for "complicated papers" (often matte fine art papers) using Excel before I continue in the EyeOne software, and it works fine - just obviously not the most efficient workflow. I use averaging when I see banding in gradations from my test prints, and that usually solves it.

The other complaint is that I think (others might help filling in here since I'm also curious) that the maximum EyeOne Photo test chart containing 918 patches is not enough for all papers to make smooth transitions mainly in deep&rich shadows. Again, this concerns mainly matte fine art papers. Glossy ones are quite easy to profile. I've run into this problem in another recent thread (regarding profiling for ImagePrint) where I got help to solve one error (my software settings) but still can't get an enough smooth profile for a specific paper, using the EyeOne Photo package. I think I need larger test charts (more patches) to make an even smoother transition. And for that I need another software.

The alternative is the ProfileMaker 5 Photostudio Pro (from Gretag/X-rite, but there are of course other software) but it's an expensive option. It has averaging, larger test charts and more.

(Note: In Sweden there is a 50% discount if you order the PM5-package at the latest tomorrow (december 13). Last year in december the same discount were offered and it then seemed to be an international campaign. Maybe the same this year and something to investigare before you buy? I will upgrade to PM5 and see where that leads me.)

Petter

Petter-

I did notice some banding on my test prints. How do you make a profile with averaging? Actually average out all the numerical data? Wow, sounds like a lot of work, and how do you make the resulting profile then with those new numbers? Anybody here make profiles using the "averaging method"? I find it hard to believe that is what inkjetart profiling service is doing.

The profiling service companies uses PM5 or similar software so they have the ability to use averaging. But whether they use it or not is another question. However, in some cases the difference is very obvious (when comparing profiles created using avering or not).

A little off topic: My basic workflow for "Excel-averaging": 1) read the chart at least 2-3 times but don't create the profile, just save the data. 2) import each file containing the measured data into Excel - using one sheet for each file/set of data*. 3) Duplicate one of the sheets into a 4th sheet .4) On the 4th sheet, let Excel calculate the average of the measurements from the three original sheets, placing each value in the corresponding cell on the 4th sheet, and limit the decimals to 4. 5) Export the 4th sheet into a text file (tab separated). 6) In the EyeOne software, create the profile using the values from your new file instead

(* This is the basic workflow - you might run into small problems when importing the data, at least if you're using "," instead of "." for decimals in your country&software as I do. Then you might have to use a work around in order for Excel not to change the values while importing (!). To check if this problem occurs you can simply open one of the data files outside Excel, in a plain text software (or Word), and check if the data seems to be identical to the data in your sheet.)

And while we're at it ... instead of measuring the same chart 3 times it's better in theory to print 3 charts and measure them once each and then do the averaging. (And then you should also walk backwards in circles around your printer while it prints the charts, 3 times or more, to transfer positive energy to your ink jet!  )

It sounds like PM5 is the better option for creating quality printer profiles.  It would be frustrating to spend $1500.00 on Eye1 Photo just to get Matte profiles with banding in the shadows, and limited profile editing options.

I have started another thread under MFDB:

http://luminous-landscape.com/forum/index....showtopic=13639 (http://luminous-landscape.com/forum/index.php?showtopic=13639)

I think PM5 would be useful to create custom camera input profiles (for my P45) using the SG chart.  I would guess I could emulate Velvia vs Astia, create portrait profiles, or make more creative effects with input profiles.

In the past, I have really liked the Nikon Color Mode III setting to emulate Velvia, but it is only available throught the Nikon software.  With PM5, I might get the same velvia look through C1 pro.

I just found out it's the PM5 Photostudio Pro that has a discount of 50%, not PM5 Publish Plus which is required for averaging (and to be able to make your own charts). You can buy Photostudio Pro and upgrade the Measure Tool ($$ !) to get averaging at least, but if you would like to make your own test chart that's not enough. This information is from a salesperson in Sweden, maybe Publish Plus is on discount in other countries?

What's the average deltaE for the differences here? I suspect you're wasting a lot of time doing this. The EyeOne will scan 100 samples per second. You're getting an average reading per patch (slower, you get more). On a device that's consistent over the sheet, averaging doesn't buy much of anything.

I base this only on practical experience. When profiling papers like the Hahnemuhle PhotoRag BW (for Photoshop) I noticed banding in some vivid colours. After doing 2 or more extra measurements and then averaging the data the banding dissapeared. I don't do this for glossy papers. And I thought PhotoRag to be a quite easy paper to profile, but all I can say is that I've got better profiles after averaging. The same has happened when profiling other paper like Hahnemuhle's William Turner and Fredrix Canvas.

The fact that the profiles sometimes gets better puzzles me but in the end I judge with my eyes. (And I don't like the time consuming process of measuring so I wouldn't do it if I felt I didn't need to.)

I think that it would be informative to run another spreadsheet showing the deltas between the readings you are getting so that you would have an objective vs a subjective measurement.  If you have any software that can calculate delta-e values between measurement files that would probably be very helpful also.  As Andrew said, you are already getting multiple readings per patch that are averaged, so I'm not sure why you are seeing a visual difference unless there is something else going on here that is affecting the measurements.

The current version of Eye-One Match will read targets larger that 918 patches but it's a bit of a fiddle.

Download Bill Atkinson's Eye-One Pro Targets from here:

   [a href=\"http://homepage.mac.com/billatkinson/FileSharing2.html]http://homepage.mac.com/billatkinson/FileSharing2.html[/url]

Pick one (I use the 1728 target), rename the reference file to "i1 Easy RGB 1.2.txt" and replace the file with the same name in the Eye-One Reference Files->Printer folder. Rename and save the original if you want. You can then read and generate profiles with Match based on the larger target. However, I prefer to use PM5 MeasureTool (a free download), measure the target three times and pick the best reading. You can use the Compare function to work out how close they are to each other and whether you've got a bad reading or not. When using MeasureTool, make sure you turn on the Spectral option to record spectral data so Match can detect OBAs and filter these accordingly. The main attraction of using the Eye-One package (3.6 and later) is the "LOGO Colorful" tables for Perceptual rendering.

I don't know how to calculate the delta E, but for anyone who is interested in doing the math I've uploaded two Excelsheets to:

[a href=\"http://www.matbilder.se/test/glossy.zip]http://www.matbilder.se/test/glossy.zip[/url]
http://www.matbilder.se/test/canvas.zip (http://www.matbilder.se/test/canvas.zip)

The glossy.xls contains 3 data sets/readings (3 sheets + the sheet for averaging). It's measured on a glossy no-name-paper similar to Epson Photo Paper Glossy.

The canvas.xls contains 5 data sets and also another routine for averaging which only uses the 3 best values for averaging (meaning the highest and lowest value from the 5 data sets for each cell is not used). (This is overkill, yes.) Measured on one of Fredrix Canvas.

Happy computing!

Download PM5 from here:

   [a href=\"http://www.gretagmacbeth.com/index/support/support-center-list.htm]http://www.gretagmacbeth.com/index/support...center-list.htm[/url]

MeasureTool needs a dongle for full functionality, but without it you can still do measurements and compare them, but not average them. It's more flexible than using Match and works great with Bill's targets. You just then feed the (chosen) output measurement file to Match.

"LOGO Colorful" is a gamut mapping option introduced with PM5. It defines the tables for Perceptual rendering. It's now the default (and only) option for Match. Just about any profiling package will generate much the same tables for Colorimetric so what distinguishes one from another is the quality of their Perceptual tables. With PM 5.05 (and later) or Match 3.6 (and later) you can now use Perceptual for most output, except where absolute colours are important (such as portraits). You can evaluate the quality of the rendering with soft proofing in Photoshop. Turn BPC on or off, whichever gives you the best results (you'll have to test this for each paper you use). Perceptual rendering will generally result in more shadow detail than Rel. Col. with BPC on.

Your Eye-One kit is a killer package. Learning how to get the best from it will save you heaps in printer/paper churn!

How do you create the profile with a txt file?
I have to go through all the steps calibrate, read swatches, etc… before I get to create profile.
I'm using Eye-One photo that I'm renting. Iwas able to profile 6 papers and It's just amazing how well the all match each other, and the monitor.
This averaging technique sounds interesting, and I'd like to try it.
thanks for your help

Forget the averaging for ink jets, it's a big waste of time. If you're profiling an older printing press that shows deviations across the sheet then yes, measure targets that you've placed in all orientations (up,down,left,right) to fill the sheet, average that and the press run from start, middle and finish. This is a variable process! An ink jet is a very stable process.

The inkjet is stable. The user's hand is not. You've been spoiled by your friend Isis
A guy using the i1 SDK once told me "doing a single (unchecked) reading with an i1 is suicidal".
Also, I'm not so sure that the Canons and HPs are so stable across the page. As the heads heat, problems may occur. Epsons are Piezo, as we all know, so inherently do not have this issue.

Agreed. Which is why I use Atkinson's graduated targets (bad patches stick out), read the target three times and take the best one. On odd occasions I'll actually edit the measurement file and fix a bad patch or two. It would be great to have software to do this, but I'm not prepared to pay what GM want for full MeasureTool functionality. I just did this for a new profile and the second and third readings were very close. I then just used whichever of these two was closest to the odd man out. MeasureTool's comparison function is really nifty.

It's you time....

There is error checking. The EyeOne does 100 samples a second so you had better have a stroke while measuring to warrant all the additional time doing this multiple times and averaging. But if it makes you feel better, by all means do so.

True enough ... but I'm not doing profiles commercially. If I did, I'd have a table. To read a 1728 patch target three times, compare and generate the profile took me about 30 minutes. Prior to this I spent a couple of hours doing media type and color density selection. Plus the overnight drydown. I use few papers but want the absolute best I can get from them.

Post by: Jonathan Wienke on January 27, 2007, 06:28:46 pm
I'm careful about measurement technique; making sure there isn't a colored surface under the paper to bleed through and skew the results (this ruins a lot of homemade profiles) making sure there isn't dust bunnies or paper dust on the charts to skew the readings, moving the spectro at a slow steady speed, etc. I haven't encountered enough variation between measurements to make averaging multiple measurement sessions worthwhile. But if you want to, it's your time, and you aren't likely to hurt anything.

I tried your suggestion, but it didn't work for me.  I have version 3.6.1 and it seems to be limited in the following ways:  It refuses to consider more than 2 strips, and it refuses to look at more than 34 rows.  So when I try to measure a set of charts for 1728 patches, I1 Match will only consider the first 34 rows whereas the Bill Atkinson charts have 48 rows.

Any suggestions?  Thanks.

I'm not sure that you can use Match to read the larger targets, but you can use Match to generate profiles based on the measurements that you already have using the larger targets. Let me clarify. You should use MeasureTool (part of ProfileMaker) to perform the measurements using the big target. ProfileMaker will let you read targets without a dongle. Save the measurement results to a text file.

Then do the trick you did above with replacing one of the target files for Match with the big target.

Then when you open up Match, instead of performing measurements there, you read in the measurements you made in MeasureTool by loading the saved text file. Then you hit the Next button and Match goes ahead and builds the profile.

This works on Match 3.6.1 on Windows for me.

For what its worth I also have used i1 photo and migrated to Profile Maker Photo.  The main reason was that no matter how many patches are/could be read there probably would have to be some profile editing.  i1 doesn't allow the kind of fine tuning that Profile Maker does.  Also, the need to understand what colors to adjust is critical for a successful final profile.  

I have a Canon iPF8000 and it had a 'hot' yellow/green cast from the profile generated from i1. I could get it out with the editor but at a cost.  The editor went too far in the opposite direction making certain tones neutral when they should have had some color.  

Profile Maker got me much closer with the profile it generated but there was still this slightly hot yellow/green cast that I wanted to get rid of.  The profile editing module is much more precise than i1 and it also has a preview that 'really' allows you to see what's going on when a curve or adjustment is applied.  The resulting profile is the most accurate I've ever used and what is seen on my monitor is 'really' what comes out of my printer.  The colors and black and white levels are very accurate - more accurate than anything I have used in the past and this includes anything from Imageprint.  What is even more interesting is that the Black and White images (when using my profile) are dead on.  I've never seen anything this neutral for black and white coming out of an ink jet printer - much more accurate than using the Canon plug in and converting to black and white.  

I am not a master of this program but so far it has been worth every penny I have spent on it.

I'm not sure that you can use Match to read the larger targets, but you can use Match to generate profiles based on the measurements that you already have using the larger targets. Let me clarify. You should use MeasureTool (part of ProfileMaker) to perform the measurements using the big target. ProfileMaker will let you read targets without a dongle. Save the measurement results to a text file.

Then do the trick you did above with replacing one of the target files for Match with the big target.

Then when you open up Match, instead of performing measurements there, you read in the measurements you made in MeasureTool by loading the saved text file. Then you hit the Next button and Match goes ahead and builds the profile.

This works on Match 3.6.1 on Windows for me.

That did the trick.  Thank you.

As for the results, other than taking more time, it's not clear to me that I get better results than with the regular 918 patches.

...  My understanding is that the "Pro" model printers are linearized at the factory. ...[a href=\"index.php?act=findpost&pid=89990\"][{POST_SNAPBACK}][/a]

Actually I think the only difference in the 2 is the Express Digital software that is included with the pro version.  Doubtful they would actually run the printers through different processes - and I can't imagine them selling a printer that wasn't calibrated.
