FWIW I cannot use this method using a CMYK profile. Avoiding color management in Photoshop then becomes academic. This gives the benefit of soft-proofing and control over BPC. This experiment, although by no means definitive, convinces me that the best way to use PrintFab is to truly let Photoshop manage colors. PrintFab doesn't have an option for BPC but this suggests to me that PrintFab is using BPC by default. The Photoshop print was done with BPC off.
What I found interesting is that the biggest differences are in the two darkest greys with Photoshop giving lower L values. Comparing the two prints in MeasureTool this is what I got. For the latter I used AdobeRGB(1988) as the document and printer profiles. I printed once using the conventinal "PS manages colors" way and once using the PrintFab null method. I wasn't prepared to waste good paper so I only printed my version of the ColorChecker24. This thread prompted me to do a comparison of the two ways of printing using PrintFab on the Windows platform.

This method gives me the same kind of accuracy as I would expect from using the Epson driver - no better, no worse. Naturally the (RGB) profile is generated from targets printed using PrintFab. I just set PrintFab to "No correction" and then let Photoshop manage colours. I have always found the "null" method clumsy, and consequently I have used PrintFab in exactly the same way that I use the Epson driver.

Thanks to all for helping clarify this and for Andrew for suggesting how to test it.Īs an occasional PrintFab user (I only use it for panoramas to overcome the 95cm limit on the 3880) I have followed this thread and other PrintFab related threads with interest. In Windows you can use Qimage, although at present you don't have to. In MacOS you have to use Print Tool I guess. This confirms the correctness of that statement, whoever said it (I think it was Jeff Schewe). I'm sure that I read somewhere that the Photoshop warning that you get in Windows about the "null profile" setting is just to have similar messages across the two OS, even if the actual behavior is different.

The "null profile" setting doesn't work on a Mac but it does on Windows, at least at the moment. This demonstrates that Windows and Mac are quite different. I've also done a couple of real prints, and as you'd expect, I can't spot any difference. Measured in Match3 3.6.2 using an i1 Photo V1 and compared in Measure Tool 5.0.10.
#Printfab stuck on sending data to printer Patch#
I took a simple 288 patch one-page chart, converted it to the printer profile for the paper in question, and printed using both Photoshop with the "null profile" setting and also ACPU. Looking very closely, I did see some differences. There were no obvious difference to my eye until I carefully compared the two side-by-side. I will say here both printed charts I used for comparison, one using a CMYK profile with the PrintFab route, and the other using the RGB profile generated through the Epson driver, did compare favorably. This should provide me with a more definitive result. Perhaps this unorthodox technique only works for PrintFab? I will try to replicate Andrews results. But I do not have a verified RIP available to me. The results would be better compared without the green tint in the result with PrintFab. Test Chart printed as RGB file with Epson driver, using Photoshop color management with an RGB profile created with same tools. Test Chart printed as CMYK file with PrintFab, using Photoshop color management with the built CMYK profile.

I have no reason to believe the profile generation software used in both cases is at fault. Other than a subtle green tint to the PrintFab print, both Delta-E error report compared favorably.
In both cases the printed color managed target was compared to the reference values provided by the target generation software for the color patch chart used in the comparison. The CMYK target was printed using what others here are calling the "null profile" approach to disabling color management within PS. The same color patch chart was printed using the CMYK profile through PrintFab. The target for the RGB profile was printed using the Adobe print utility. I have compared a standard RGB profile where a color patch chart was printed using managed color within PS.
