I recently built a profile for Ilford Gold Fibre Silk using Bill Atkinson's 1728 patch target. The prints that I am producing are darker than I would expect from softproofing results. Today I printed an image using the canned Ilford profile and mine. Softproofing shows them looking identical but the canned Ilford profile is lighter and much closer to what I see on the monitor.

Plan A is to print the targets again and then remeasure and build a new profile. My assumption is that I did something wrong along the way when building my profile. What has me rattled is that the monitor looks the same for both but the results are quite different.

If there is anything obvious that I am doing wrong, I would be very grateful for the advice.

Thanks,

Jeff

Based on what you say it sounds as if your custom profile didn't load properly, or you had settings in place either in Photoshop or the Epson driver which interfered with its functionality. I would suggest double checking that the profile is correctly installed, that colour management is turned off in the Epson driver, that the profile is identified in the Photoshop Print control window (if you are using CS3) and that in the same dialogue Document (not Proof) and Photoshop Manages Colors are selected. These are the usual culprits for the kind of problem you mention.

To add to Mark's comments: are you sure you used the exact same driver settings when printing the target as when printing your real test images?

Assuming there is no double profiling going on, there is no reason I can come up with as to why two softproofs should look identical while the prints differ.  Is it possible that one was either softproofed or printed with a mismatch in rendering intents?  Could one of the profiles be optimized for a different viewing color temperature?  Is it possible that your homebrew profile is damaged?

There's not that much you can do wrong here that would produce this effect, assuming the prints really are dark (and not just darker than the display). If you measured a few patches wrong, boy, you'd see it in the soft proof let alone print. Can't hurt to reprofile again (I've seen it work). It probably is either a driver setting when printing targets or something else I suspect.

Added to Andrew's comment, when printing the target best to verify that you have No Color Management selected in BOTH the printer driver AND in Photoshop.

Thanks for all the feedback,Folks, and apologies for going silent. I am about to rebuild the profile but I'm going to use the 918 patch target that comes with Match. Looking at the two profiles on Colorsync, there is quite a difference. My profile is mapped over the canned Ilford profile.

I can only surmise that I have stuffed up somewhere.
