It's normally trial and error. I find that most of the time you don't need to adjust it from the default of "0". Usually a 5% or 10% does wonders when needed.

Thus with your favorite paper and profiling with the ColorMunki you would print 3 sets of profile target prints at 0%, +5% and +10% Then generate the 3 profiles and print test prints, but remember that when you print the test prints, you need to make sure you use the settings that also include the 0%, +5%, and +10% adjustments.

You can save any printer settings in the print driver for future call up during printing so you don't need to manually make adjustments to settings each time you print with a different paper.

NOTE: If you ever save custom printer settings in the print dirver, also export them to another folder on your hard drive. For some reason R3000 custom settings just disappear from the printer driver for no known reason, having them in another folder allows quick import back into the printer driver than to try and remember how each was set up.

Thanks for all the advices, I will backup my settings!

So, if I'm not wrong, this is a global setting (not per ink channel) and if I print the calibration patch provided with QTR with Epson driver can I try a first adjustment "by eyes" if needed, correct?

And someone tried QTR with Colormunki Photo on R3000? Can Colormunki be used with QTR to linearize their curves too, at least for non OBA papers (I think that OBA's could fool the Colormunki out but not so sure)?

And finally back to the topic:

Today I will try again a flattened HM Photo Rag Pearl sheet to see if I'm able to workaround it, if I succeed I can consider to keep my printer, what do you think?

Thanks a lot!

Colormuki Photo, as far as I know can only print and scan its own proprietary patches. Only 50 per print. If it can scan other charts, I am not aware of that, and you love to know more.

Watch my videos!!!!!

When you create a profile with it, the CM software sends a proprietary chart with 50 patches of known color values to the printer. You set you printing parameters inside your R3000 driver:

MAKE SURE YOU HAVE A PERFECT NOZZLE CHECK

MAKE SURE YOU HAVE RUN AN HEAD ALIGMENT

Paper Type = chosen from your drop down paper choice menu

Printing quality = either 1440 or 2880

Either high speed ON ( bi directional ) or high speed OFF ( Uni Directional )

You can now also choose other parameters such as you platen settings. To tell you the truth I have not even touched any of those settings and I print out to MANY different papers an thicknesses.

Now for the MOST IMPORTANT SETTING!!!!!!!!

TURN OFF COLOR MANAGEMENT = Set it to NONE

The goal is to see whether your printer/ paper and ink compbo can print those specific color patches to the correct values WITHOUT the printer driver tampering with the colors being set to it.

By scanning resulting patches after the print has dried, with your colorimeter ( colormunki ) the software will gather up the resulting read values of each color patch, compare the numbers with the original numbers sent to the printer and, determine exactly how much OFF they are. The sofware will now create a second set of color patches to "NEUTRALIZE" the errors found. You print that second chart using the SAME EXACT settings and after drying that chart, you again scan it with the CM, the software will then process all the information and high math, create the correct ICM profile for that particular printer / paper / ink combination.

If you switch papers, you will need another profile. If you change inks, you will need another profile, you get the idea?
