I am suddenly getting poor washed out prints with poor color accuracy printing with icc printer profiles in Photoshop CS6.
I am printing exactly as I have been with this same printer, same settings, same paper, same inks and same profiles for 18 months.
My first suspicion was the printer itself, though I checked the heads and everything checked out: no clogged heads. A head cleaning did not do the trick.
I carefully created two new color profiles using an x-rite i1pro 2 spectrometer. Comparing the results to older profiles indicated little differences,
Still washed out distorted colors.
I then tried printing from the Epson generic drivers using both sRGB and Adobe RGB, giving color control over to the printer.
Zap, the colors were back, full intensity and fair accuracy given that the printer profiles were generic.
Still, whenever I try to print giving color management to Photoshop, regardless of the profile I use (I have now tried quite a few), I get washed out and distorted colors.
Does anyone have any idea what is going on, any similar experience, any thoughts, suggestions, or anything else.
Thanks,

Sounds as if the printer is fine and that there is a colour management problem somewhere in the colour management pipeline between the CMS and Photoshop (are you Colorsync [Mac] or ICM [Windows]?) . If you have Lightroom, try printing the same image out of Lightroom and see what happens. If you are on Mac greater than Snow Leopard, go to the PrinTao website of LaserSoft Imaging and download a free demo of PrinTao, and try printing the same photo from that, because it does not use Colorsync. If you are getting good prints from the non-Photoshop alternatives, it would suggest there is a corrupted Photoshop setting that somehow crept in.

Thanks. For your help.
I'm on a Mac Running Mountain Lion. I have not been using Colorsynch. Normally, I give color control to Photoshop and specify an icc profile for it to use. IU've had better luck making my own profiles that using any of the manufacturers.
Since I started having this problem, I had some success turning color control over to Epson during printing, for which it seemed to used a generic sRGB or Adobe RGB profile. As I said in my original post, the results were much better letting Epson control things than printing with a profile through Photoshop, though this takes away my option of using an icc profile (other than whatever default Epson uses). I also tried giving color control to colorsynch and specifying a profile and got really bad results. There seems to be a bit of confusion in the driver somewhere about who is controlling what, as, when I believe I had things set for colorsynch, the driver complained that there might be a conflict in who is controlling the color.
Per your suggestion, I just spent 45 minutes trying to figure out how to use PrintTao8. I can't figure out how he is getting anyone to pay $500 for the software. It won't even let me specify the size of my sheet, seemingly limiting paper to standard commercial sizes. I had to track down some paper scraps and cut then to his specifications.
The only place I can see to tell the software what profile to use is in the media manager, but then, after saving that "media" I found no way to select that profile in any printer interface.
I also couldn't figure out how to get it to print. Went through and selected a bunch of stuff (which all seems to be the Epson driver interface stuck into new windows in a confusing way) and clicked on print (even though I could find nowhere to select a printer profile). In response to that, the software went through a quick process in a window that looked like it was sending something to the printer, but nothing ended up in the printer queue nor came out of the printer.
The media manager is odd as he keeps downloading stuff from paper manufacturers none of which is any help to me. It seems like one of those "What me worry?" kind of programs.
Go figure.
I like your approach of eliminating pieces of the process to see which is causing the problem. Given that it puts out a better print giving Epson control of the printing, I would think that this probably indicates that Photoshop is the culprit. It would be nice to try another method (e.g. PrinTao8) if I could get it to work.
At any rate, I have no idea how to get Photoshop to knuckle under either. Do I re-install it??? Is there some preference file somewhere that needs deleting??
I feel clueless clueless???
I do have a copy of Lightroom, though I don't use it regularly. I actually use Aperture to organize my images (I am printing original artwork and artwork reproductions), but have never found printing from it to be as straightforward as Photoshop. It is a bit like PrinTao8 as it seems to rename all the parts of the printing process, I suppose, thinking that it is dealing with humans that don't want to know what is going on. For me, not knowing what is going on just makes things more confusing.
I will report any further developments.
Any further thoughts would be appreciated.

Hi Kenoli,
You probably don't know it, but if you are printing from Photoshop with Photoshop managing the colours you are are using Colorsync. It is the colour management system that operates under the hood to connect profiles and transfer colour information from one place to the next.
As for PrinTao 8, if you are going to use a new piece of software, please first read the manual so you will know what you are doing. I am preparing a review of this application, I have been testing it quite extensively and I assure you that by and large it works fine.
If you are getting notice that there may be double colour management happening, you need to make sure to turn off printer colour management in the Epson driver if Photoshop is managing the colours. Photoshop manages the colours if that is the option you selected in the Photoshop Print interface along with the profile you selected for your printer/paper combination.
-
Sorry to be impatient with PrinTao. I guess I expected it to be a bit more intuitive and this process has been frustrating.
It did actually print. The printer had hung and I didn't notice it. The results were quite good, though I never did exactly figure out how to assign a profile, so I'm not sure what profile it was using.
I hear you regarding color synch. In the printer driver, when Photoshop is selected for color handling in the Photoshop dialogue, I can see that in the printer dialogue's color control menu colorsynch is selected and grayed out. I presume this means that it is being used and that when I indicated an icc profile in the Photoshop part of the print dialogue, Photoshop is simply sending this through to color synch (or deferring to color synch).
When I run ColorSync Utility, I can see that colorsync has a profile associated with each paper type. I guess what this means is that when I choose s paper type, colorsync would be inclined to use that profile. I also guess that what happens when I select a different profile in the Photoshop dialogue, Photoshop substitutes this profile for the default set in ColorSync Utility.
What you are also saying, I guess is that when printing with PrinTao, colorsynch is taken out of the equation (Is this correct?).
If so, this means that since the print I got with PrinTao is quite good, and I am getting poor output when printing from Photoshop, the problem must be with color synch (or some interaction between colorsync and photoshop).
Not sure what to do about this. Any suggestions?

PrinTao by passes Colorsync. It has its own colour management system and it uses the profile that is selected in the Start Pilot. If you didn't add your custom profile, it is selecting the manufacturer's profile for the Printer/paper combination you are using. That's one of the nice things about it - a lot of stuff happens without you needing to fuss over it. OK, so now that we know the Print pipeline works when neither Photoshop nor Colorsync are involved, we can presume your printer is OK and there is an issue with a setting in Photoshop or the Epson driver (when used with Photoshop managing colour) that is causing a colour management issue - because I would be surprised if Colorsync itself got fowled-up - it is buried in the OS and users hardly ever access anything to do with it except to select profiles from inside another applications they are using. I recommend that you recheck all your settings in Photoshop and in the Epson driver to make sure they are all harmonious and can play right with each other.

Thanks for your continued help.
I'm not sure what to do here.
Here's what I did do:
I went into ColorSync Utility and assigned several different icc profiles (one at a time) for the paper type I am indicating. I printed from Photoshop using the settings I always do with each profile and got poor results.
Here are my settings:
Color Handling: grayed out with ColorSync selected
Print settings:
Media Type: [the media I always use and the media selection I assigns each profile to in ColorSync]
Print Mode: AccuPhoto (grayed out) as usual
Color Mode: "Off(no color management)" (grayed out as this is the only option when I have indicated that Photoshop will handle color)
Output Resolution: SuperPhoto-2880 dpi
Super MicroWeave: checked and grayed out
High Speed: checked (the default setting I always use)
In the PHotoshop dialogue:
Color Handling: Photoshop Manages Color
Printer profile: (the profile I am using-the same as I have set as the default for this media in ColorSync Utility))
Rendering Intent: Relative Colormetric (I always us this as I am trying to keep artwork as close to colormetric as possible)
Black Point Compensation: checked
There are no other settings related to color. I am using Adobe RGB as a colorspace in Photoshop and when I scan and have been using this for some time.
The image looks good on my calibrated screen and the print output looks very washed out with some color shifts.
I can read up more on PrinTao and try printing the artwork I am working on from there, though this will only tell me what I already know.
Can you see anything in my settings that is problematic. These are the setting I have used hundreds of times.
Thanks,

I've never touched Colorsync to print. In the days when I printed from Photoshop (before Lightroom 4 made it preferable to print from Lightroom), I only ever used the Epson driver and the Photoshop Print dialog for managing everything that needed to be managed and never had the issues you are experiencing. Try resetting Colorsync to its factory defaults, then leave it alone and arrange your whole print colour management using only Photoshop and the Epson driver. Also check your Colour Management settings in Photoshop's Preferences.

Mark -- First, I want to say that I appreciate your taking the time to help me with this. We are feeling quite challenged as this has swooped down out of the blue after a year and a half of great printing results and we don't think we are doing anything different than we have. We have gotten no satisfaction from Epson or Apple support in figuring this out. I will pour through every Photoshop and printer setting I can find (I have actually done this several times already).
I also thought of a few things I can try to narrow in on what is going on. One question, does light room completely bypass ColorSync as does PrinTao, or does it use ColorSync the same way Photoshop uses it (as you pointed out to me)?
Incidentally, I did get further into PrinTao and can see that it is an interesting piece of software, once I got the hang of the workflow. Is there some place in that software to set paper sizes other than the software's defaults. I poured through the documentation and couldn't find anything. We are printing artwork of our own and some fellow artists and we seldom print to standard media sizes. For instance, when we are printing to canvas or other materials, we need to take into account extra space for stretching or hemming and even the offered sizes for role papers are set in a way that it would involve huge paper waste or be impossible to do what we are trying to do with the sizes the software specifies. And, of course, artwork itself comes in any number of "non-standard" sizes.
The big limitation for us is the same as the limitation for Lasersoft's scanning software: price. It's baffling why this software costs so much more for a wide format printer than a narrower format printer. There is not a lot more going on printing to a wide format printer. Do you know why this price difference? I guess if you want to use "standard" paper sizes there may be some cost researching additional sizes, though, of course, this is more of a limiting factor than benefit to us.
Their scanning software price is out of the park. We use several different scanners and, as far as we can tell, we would have to buy a full piece of software from Lasersoft for each scanner, when, as far as I can tell, all they are providing is an additional scanner profile which we create ourselves anyway (interestingly, when you try out lasersoft scanning software, they download all the profiles anyway). We ended up using Vuescan, which sells for $80 with a lifetime of upgrades and email back from the creator, usually within hours, when help is needed. I've researched the two pieces of software on the internet and have not been able to understand that Lasersoft provides much more, though the price is exorbitant. It was hard enough for us to afford the printer and, for us, necessary profiling software and hardware which we got from X-rite and which profiles all of our scanners and printers. Scanners are cheap by comparison.
I must say, I do like the ability to bypass ColorSync and would buy PrinTao if it didn't cost $500 and if it let me print to the paper sizes I need to print to. Another limitation is the way it sets the profile for each paper as we often use different profiles for different media, inks and the character of the artwork. Because of the limitations in the Epson driver, we have to tell it the name of a paper which may not even be the paper we use. I guess what is of use to the casual user ends up being a limitation for us.
Thanks again,

Hi Kenoli,
Lightroom uses Colorsync. If you can print well from Lightroom it means Colorsync is a non-issue.
It's not clear from the PrinTao manual whether you can create and store custom paper sizes that are not offered by a manufacturer, but you can create and save templates which may do the same thing. I know for sure that you can import into PrinTao and use your custom paper profiles.
The logic of the software pricing is not very different from how some RIPs are priced. It's market oriented. Whether the price is right of course is at the sole discretion of the buyer. Being a free market, the company will know soon enough whether they got it right; but you are undoubtedly aware that the overhead costs to conceptualize, develop, test, market and support such a product are non-trivial, so it will cost something; likewise for SilverFast 8 which was re-engineered from the bottom-up. Yes, Vuescan is a lot cheaper, completely different marketing philosophy - and different software. Every user needs to decide for themselves which floats their boat better. Both have been surviving and thriving for many years, so there is obviously a market for both approaches. The fact is that much more than the scanner profile is scanner-specific in SilverFast. While some scanners may be cheap, others are not - even compared to some of the other pricey items you mention, but the most expensive ingredient to scanning - unfortunately - is your TIME - being in business you know how time is money. So I would vote for the software that delivers the best results with the most economic use of time.
Actually, the number of paper options in the Epson driver is not necessarily a limitation, especially if you are making your own profiles. All you need the paper name for is keying the instruction set in the driver to the closest kind of paper you use. Your custom profile and the CMS does the rest and will perform as expected as long as you consistently select the same paper name in the Epson driver as that you selected when you printed the target for making your custom profile. For example, I print almost exclusively with Ilford Gold Fibre Silk. One of its nearest neighbours in Epson-land is Epson Premium Luster Photo Paper. So that is the reference paper I leave set in the Epson driver. I made my IGFS profile with Epson Premium Luster keyed in the Epson driver, but the target of course is printed on IGFS, and the patches are read and profile made off of IGFS. So the Epson driver and the profile will "know" how to interpret those colours accurately, provided I leave Epson Premium Photo Paper set as the paper key in the Epson driver and the same custom profile is used for the paper I profiled.

Mark --
Thanks again.
I was on the phone with an Apple support guy who says he is an expert in ColorSync and got lots of sympathy but not much help aside from unplug everything and let everything reset. I guess Apple now deletes and resets printer stuff when printers are disconnected. I think, however, that with the pro series printers you have to install a driver separately.
I'm dealing with hugely anomalous results.
I'm getting good results from Preview that uses ColorSync with some default profile and the same kind of horrible results from Aperture as I am getting from Photoshop which both use colorsync but let me set the profile. Same results with several different profiles.
In addition, I am not not able to set default profiles in ColorSync Utility. It just beeps at me and reverts to the default Epson profile for that paper. I presume this probably doesn't matter as both Photoshop and Aperture use the profile I tell them to (I presume) instead of the default profile.
Haven't tried Lightroom yet. I will have to install it to use it.
The best the Apple guy could suggest is to upgrade to Mavericks which will reset everything and install ColorSync with a lot of significant changes (supposed improvements). Apparently there is no way (at least he didn't know how) to reset or re-download ColorSync.
I can't find anything that tells me Epson or Photoshop has any problems with Mavericks. Have you heard of any problems? I was putting it off until I was sure.
Thanks for the feedback on PrinTao. I tend to like software that lets me simply tell it what I want to do when I want to do it rather that have a lot of default settings in the background with a condensed menu of choices. This may take a little longer, but I know that I am getting what I want. Everything everywhere seems to be targeted more and more at consumers who want decisions made for them. The way of the world . . .
Thanks,

Kenoli, a large number of serious professionals do most of their printing from Lightroom these days - it's that good, especiallly since softproofing became available. In your case, for sleuthing purposes I recommend you download a trial version and st it up to print one of your "known" images to see how the print comes out. It uses the Epson driver and Colorsync. You can manage it all from within Lightroom, and you have the choice of letting the printer manage colour, or use your profile. I would recommend setting it use your profile and load your profile. If the print comes out well, you know for sure the problem is a Photoshop setting. In this case, there have been recommendations about trashing your Photoshop Preferences file and letting it reload on restarting the application. This has been said to cure many issues of settings or files begin corrupted. Whether it remains good advice in current versions I'm not sure, so best not only take my word for it. Do some checking.
-
Thanks. I'll give LightRoom a run. I've been a bit worried about being to stuck with Adobe for the future. We are a nonprofit of artists and get a VERY good nonprofit price on Adobe products. With this switch to the cloud for Adobe, the monthly costs could preclude our being able to use Adobe products in the long run. Hopefully there will be a nonprofit rate for the Adobe cloud but so far, none. We are all volunteers or working on our own unfunded projects. It is hard to be working in an industry where money flows in large quantities everywhere but toward the artists.
At least CS6 should keep working for a while, and, hopefully, Lightroom.
I appreciate the time you have given to help with this.
--Kenoli

Kenoli, no question CS6 and LR 4.4 will keep on working for as long as you want them to and in the case of LR for so long as you use only cameras whose raw image formats are supported in that version of the raw converter. You only need to upgrade when the application version you have no longer supports stuff it wasn't designed for and you happen to be using, or when new versions come out with "killer features" you never even thought of before but all of the sudden become indispensable because they exist. (In the language of economics - "supply creates its own demand"). Think of how much business is driven by that.
I hope your next round of research solves the problem.

Hi Kenoli,
You probably don't know it, but if you are printing from Photoshop with Photoshop managing the colours you are are using Colorsync.
But ColorSync will not do any transforms or modify the colors if the correct options are selected and the images are properly tagged. This is why the ColorSync option is greyed out. The only time this can be problematic is if the file is untagged, then ColorSync becomes proactive assuming it needs to be. This lead to the problem of printing untagged targets in the past.
When I run into stuff like this a good first step is to clean things out and start fresh. Some thought's on that here (http://www.cwaynefox.com/wordpress/epson-printers-and-lion-and-leopard-and-snow-leopard/) if the OP is interested.

I'm very interested and will check it out.
What do you mean by "tagged."

What do you mean by "tagged."
Basically means the image has been assigned an appropriate working space profile.
-
Wayne --
Basically means the image has been assigned an appropriate working space profile.
I presume the same thing applies if an icc profile has been assigned by PhotoShop in the printer dialog, i.e. ColorSync defers to the indicated icc profile.
What I am getting here is that ColorSync's function is to step in and apply a default profile if none is sent along by an application like PhotoShop, Aperture or LightRoom. I'm not sure what else goes on, i.e. if ColorSync is involved in getting an image to the driver or processing either a default profile or an assigned profile. But the main thing here is what profile gets applied, not so much how.
I just followed the suggestions in the link you send and uninstalled everything. I'm now re-installing drivers and will post the results.
Thanks,
--Kenoli
-
Wayne --
I presume the same thing applies if an icc profile has been assigned by PhotoShop in the printer dialog, i.e. ColorSync defers to the indicated icc profile.
It is possible for the image to not be defined in a particular color space, and selecting a profile in the print dialog is choosing the destination space so it's not the same profile. This is basically a defined working space, commonly adobe RGB or ProPhoto RGB for photographers, sometimes sRGB.
This is very rare, and if your profile warning boxes are checked then you would get a warning. Basically it means the file itself does not have a "color space" attached to it. Photoshop can do several things if this happens, from leaving it alone to automatically assuming a space. When using camera raw, this space will be set when ACR sends the file over to photoshop based on the settings at the bottom of the ACR window.
So it is pretty uncommon and indeed you almost have to intentionally do something to avoid having the image associated with a working space, but I suppose it can happen. For me I always tell my students and others to leave the profile mismatch checkboxes on in the color settings option in the menu. Then you will always get a warning when anything is out of the ordinary, and can appropriately deal with it.
I don't suspect this is your problem, it really sounds like you may have a corruption somewhere based on your original post of this happening suddenly with no changes on your part. That's why I suggested trying the reset which should clean that out to either confirm or eliminate that as a possibility.
I assume you have done no OS upgrades or anything that might have caused this to start?
-
Wayne -- Thanks.
I hadn’t done any major system level changes on my computer that I would suspect of creating my issues. The only thing I could identify was to let Seagate install a drive that gives the Mac access to NTFS formatted hard drives. I've put in a support request to them.
In trying to deal with my issues, I talked with a ColorSync “expert” at Apple who encouraged me to install Mavericks as he said there have been some useful changes made to ColorSync and upgrading would reset things.
I did the upgrade. The good news is that Mavericks didn’t seem to interfere with any functionality and actually performs better. The bad news is the same, nothing changed in my ColorSync or printer settings. So, I went through a full reset. I’m still having similar print output issues using Epson's default profiles and am in the process of making new profiles for everything. I will send a report when I get the results. I did reset photoshop per instructions from the Adobe woman on Youtube who I have gotten good advice from in the past. If things persist, I guess the next step is to uninstall and reinstall Photoshop. We’ll see.
I am using, or trying to use a consistent color space, namely Adobe RGB. I did a bit of research and decided this would work best for our application, which is original and reproduction art prints. Most of our input is from a scanner and I have it set our scanners to output an Adobe RGB embedded profile, though I notice that whenever I open a scanned file, it asks me if I want to change the embedded profile to match our color space which is also Adobe RGB. Go figure... I have been planning to check with the scanner software support to see why this is.
It's probably not critical to know, but I am curious where and how ColorSync kicks in and how it interacts with Photoshop and the monitor and printer profiles. Does ColorSync handle all of this. Does the embedded or working Photoshop color space affect what comes our of the printer, or simply how it is seen on the monitor? In other words, will my print output look different depending on the Photoshop color space? I would think this last matter is the most germane to my issue.
Thanks,
—Kenoli

Kenoli, I think you are too concerned about Colorsync. I doubt the problem you are having is at that level, unless you have interfered with it - and if you have, get it reset to its defaults. I think you need to follow Wayne's instructions to the letter re uninstalling and re-installing the printer driver and the printer as he suggested. I also think resetting your Photoshop Preferences files could be helpful. Try doing those two things ONLY and see whether the prints start to come out better.
-
Wayne and Mark -- I'm sure you're right, Mark: it doesn't really matter what ColorSync does. I just get my curiosity whetted. I reset everything and re-installed all the drivers and created new printer profiles and it looks like everything is back to "fine." In the process I did discover that my scanner software is embedding my scanner icc profile as a color space (i have no ideas what that means) in the images it outputs. Not sure why this is or the implications, but I am looking into it.
Thanks to both of your for your support and ideas. It was a good learning experience, everything is working and I'm upgraded to Mavericks.
Warm regards,

really glad to here things are working again. Regarding the scanning and scanner profile - what scanner and scanning software are you using? What colour management settings in the scanner software?

Hope I'm not hijacking things here, but my problem with PrinTao8 is along the same lines; i.e.. its performance is a bit erratic regarding profiles. If I open a .tif file in LR from the Mediathek, sometimes it shows the image to be a jpeg with the red coloured warning in the optional metadata box underneath. There's also a yellow warning triangle in the top right hand corner of the image in the central layout. Hovering my cursor over this shows a 'this image has not been assigned a colour profile' warning. Can anyone make sense of what's going on and what I'm doing wrong. (iMac 27", Mavericks, full purchased PrinTao8 version, up to date).

Sorry, re above. Epson 7900.

seems you would be better off starting a new thread describing your problem in the title, especially the name of the software you are having problems with. Somewhat related to this thread but enough different so you may not be getting enough looking at the thread. I have no experience with the software you mentioned or it's functionality.

First I would like Mark Segal to know I wrote a review of Printoa 8.
I am having a heck of time with Printoa 8. I have the Epson Pro 9900. Computer is the MacBook Pro 17 inch non-glare display, 8,3. The external display is the NEC MultiSync PA 272w.
What happens is intermittent: On left of image, vertical solid black line. Sometimes one inch wide, other times, 1/4 inch wide.
Incomplete printing of image file. Both vertically and horizontally.
Darren Vena of LSI, gave me a procedure I followed exactly and it did not cure anything. It was removing absolutely anything, anywhere, pertaining to Printoa 8. Reboot, then empty trash. Get the download again, and reinstall. The Epson Pro 9900 was to be turned off. I unplugged it for five minutes. Turned it back on. Made sure the USB printer cable was plugged directly into the computer. Turn on printer and then reinstall the printer in Printoa 8.
I really need suggestions and help. I have waste ink, canvas, and my time.
When Printoa 8 works, it's great. I resent wasting my time, ink, and canvas when it does not work appropriately.
Cheers
