I have been using Qimage and Profile Prisim for many years, using an Epson R1900.  Have always had the Epson set for ICM with no color adjustment with the ICM profile set in Qimage.  All of a sudden, color of prints turned bad, a reddish tinge, a grey floor would show up as a reddish brown, all colors just not right.  Nothing on my set-up had changed, just lousy color on prints.

I played around with different profiles, made sure no jets were clogged, checked everything (and wasted ALOT of paper).  Finally, just to try something different, I loaded the same ICM profile I have always been using on the printer, set Qimage to let the printer mange the color.  Prints now look normal, a grey floor looked grey, back to where I have always been.  Using Qimage 2019.106. (The problem was with earlier version of Qimage as well) I am at a loss as to why I now need to have my printer manage the ICM/color and can no longer let Qimage manage the output.

Puzzled with alot of scrap paper. Anyone have any ideas?

Are you sure you weren't double profiling when you were getting the off color prints - that is - setting the profile in both QIMAGE and the driver ?  That is one of several different methods I have used to mess up my prints.

Positive that ICM was set to only be used by Qimage, Epson set-up has "No Color Adjustment" set.  That is what is so confusing, I agree that is seemed like double profiling but verified multiple times that all colormanagement was off in the the printer set-up.

I guess it is possible that even though I had the Epson setup for no color management, it was still engaged somehow.  As I stated, this just started happening with no configuration changes made, was in the middle of printing out some presents and it began.  Now that I have figured it out, I guess the presents can be "New Year" gifts.   Roll Eyes

Hi Gib,
I would love to help but I am in need of clarification as to your terms.
What do you mean when you say you loaded the ICM profile.?  What is an ICM profile?
What did it say in the profile box in Qimage, OFF and you left the check in the driver on ICM?

Next you loaded the "same" ICM profile, but this time, you "Set Qimage to let Qimage manage color"
Please clarify what you did step by step.

Thanks,
Fred

I have been using ICC profiles created in Profile Prisim for years for printing.  ICC profiles have a .ICM file extension, that is why I refereed to them as ICM.

I have always used Qimage to manage the printer color, selecting the appropriate ICC profile in the "Printer Profile" option of Qimage.  In the Advanced Options section for my Epson R1900, I have always set Color Management to "ICM, No color Management".  These are the correct settings to have Qimage control the printer output via the ICC profile set in the Printer Profile option.

This has been my setup for years, all of a sudden, the prints were no longer correct colors.  After wasting a bunch of paper trying to figure out what the problem was, when I set the Epson to use the same ICC profile I have always used, and set Qimage to "Let the printer/driver manage color", I was able to produce proper colors in the prints.  Essentially, I disabled Color Management from Qimage, let the Epson manage the color.  I just don't understand what changed and why.

Two possibilities come to mind:

(1) The profile (ICM file) somehow got corrupted.  When you set Qimage to "Let printer/driver manage color", the driver will pick an Epson profile instead of your PP created profile.  As a test, go back to Qimage managing the color but instead of choosing your PP profile, choose the Epson profile for the media type that is chosen in the driver.  For example, if you have luster media type chosen, choose the Epson Luster profile.  Does it print OK when you do that?  If so, the profile you are using may have gotten corrupted, overwritten by the wrong profile (for another paper), etc.

(2) The printer/driver settings in Qimage were changed.  Set everything up for your usual scenario where Qimage manages color and then hold the shift key while you click the "Properties" button on the Printers and Settings tab to open the driver with default settings.  Set everything in the driver manually: media type, size, quality, no color adjustment, etc. and OK those "fresh" driver settings.  Click on the small tool button to the right of "Printer Profile" and check to be sure the ICC settings are what you are used to using: in particular check to make sure the rendering intent is either relative colorimetric or perceptual.  Maybe that got changed to absolute colorimetric without you realizing it.  After taking these steps, reprint to see if the problem goes away.

Finally, sometimes when people print a nozzle check and all looks OK, what actually prints can look fine but if you are missing an entire channel (color), that swatch won't print at all and you don't notice it.  So double check the nozzles even though I know it doesn't make sense that nozzles could be the problem if it prints correctly with "Let printer/driver manage color".  Check not only for missing lines but also count the number of swatches and make sure there is one set of nozzle lines for each printer ink color.

Mike

Thank you for the information.
So your sweet setting is now precisely??
See screen snaps.

PS While I was typing this to point out exactly THAT... different profile, Mike got in there first

Will give those suggestions a try and see what happens.  Thanks for the tips.  I have verified that there are no nozzles clogged, all colors print as they should, no colors are missing.

Fred,
I did notice in the first set of screen shots, you show the R1900 options with "ICM" selected, but also show "No color adjustment" not enabled, with options set in the lower sections.  From what I have always used, I had enabled the "No Color Management" which greyed out the other options -

Mike,

After reading your response again, if the the profile was corrupted, why would it work correctly when setup for the Epson to manage the color vs. when using the same profile for Qimage to manage the color the print is wrong?

Well, re-setting all of the printer options, as suggested by holding the shift key while selcting "Properties", then manually setting all printer options, has fixed the issue.  I can now have Qimage managed the colors using the same ICC profile I have always used and the prints are correct.

Thanks!!!!!!!!!

Glad the reset worked.  To answer your question...

After reading your response again, if the the profile was corrupted, why would it work correctly when setup for the Epson to manage the color vs. when using the same profile for Qimage to manage the color the print is wrong?

When Qimage manages colors, you select the profile you are using: let's say it is "R1900-Luster-Profile-Prism.ICM".  When you choose "Let printer/driver manage colors", you don't get to select a profile in Qimage: the driver selects it for you.  And when the driver selects the profile, it's going to select the Epson built profile for the media type you are using: in this case "SPR1900 Premium Luster.icm".
