Printer profile creation: Definitive print procedure on Mac

[Todd Sailor]

Hello all,

I am running Mavericks 10.9.1 and I think I am having difficulty producing a completely un-color managed printed test chart. I am using Photoshop CC and have also tried to print from Mavericks’ Preview app, but after scanning both charts, I get significant out of gamut indications in PS. Also, resulted prints appear very dull and not accurate to my calibrated (via DisplayCal) monitor’s rendition of the photo.

In the Preview app under Color Matching, I am choosing EPSON Color Controls; then under Print Settings, I am choosing the paper I’d like to use; and finally under Color Options, I am choosing Off (No Color Management). I print out the chart and let it dry, then scan it in with a ColorMunki.

In Photoshop, I really don’t know what to do. Should PS manage color? And if so, what settings should be set? Or, should the printer manage color, and if so, what settings should be set to create a non-color managed test chart print?

I am pretty sure the print is the issue, but I am also going to calibrate my monitor again as well.

Thanks in advance for the help!

Thank you!

When using the ColorSync utility, should I also under Color Options change from Manual Settings to Off (No Color Management)?

Most likely must be "Off" during target printing

The only way to "guarantee" that you are printing with no color management
is to use the Adobe Color Print Utility as Ivan already noted. I'm on
Windows but I've read on numerous forums the problems that Mac users
encounter when trying to print targets. The only versions of Photoshop that
allow you to do this are CS4 and earlier; you cannot use Photoshop CC to do
this.

So what's the workflow like, using Adobe Color Utility?
I'll bet there's more information on Adobe's web site?

Just download the utility, create your test charts in ArgyllCMS the usual
way with whatever flags you use. Launch the ACPU utility and open up the
target TIFF files you created and print. The only thing you have to do is
make sure that you select the correct paper setting for your printer (type
and the size you specified in printtarg). The ACPU is not color managed.
Directions on the Adobe site that Ivan posted are pretty clear.

Just download the utility, create your test charts in ArgyllCMS the usual
way with whatever flags you use. Launch the ACPU utility and open up the
target TIFF files you created and print. The only thing you have to do is
make sure that you select the correct paper setting for your printer (type
and the size you specified in printtarg). The ACPU is not color managed.
Directions on the Adobe site that Ivan posted are pretty clear.

So what's the workflow like, using Adobe Color Utility?
I'll bet there's more information on Adobe's web site?
Thank's / Roger

The only way to "guarantee" that you are printing with no color management
is to use the Adobe Color Print Utility as Ivan already noted. I'm on
Windows but I've read on numerous forums the problems that Mac users
encounter when trying to print targets. The only versions of Photoshop that
allow you to do this are CS4 and earlier; you cannot use Photoshop CC to do
this.

Mac
Hello all,
I am running Mavericks 10.9.1 and I think I am having difficulty producing a
completely un-color managed printed test chart. I am using Photoshop CC and
have also tried to print from Mavericks' Preview app, but after scanning
both charts, I get significant out of gamut indications in PS. Also,
resulted prints appear very dull and not accurate to my calibrated (via
DisplayCal) monitor's rendition of the photo.
In the Preview app under Color Matching, I am choosing EPSON Color Controls;
then under Print Settings, I am choosing the paper I'd like to use; and
finally under Color Options, I am choosing Off (No Color Management). I
print out the chart and let it dry, then scan it in with a ColorMunki.
In Photoshop, I really don't know what to do. Should PS manage color? And if
so, what settings should be set? Or, should the printer manage color, and if
so, what settings should be set to create a non-color managed test chart
print?
I am pretty sure the print is the issue, but I am also going to calibrate my
monitor again as well.
Thanks in advance for the help!

Not all of the images requires full AdobeRGB gamut. But they would suffer from some compression from AdobeRGB to printer gamut even if the images are inside the printer gamut.

Good. Adequate. Normal. Right.
Show us:

xicclu -v -fb -ir -pl -g a1.icc
xicclu -v -fb -ip -pl -g a1.icc

If the plots above are smooth the profile is good (takin in account low dE76). If the perceptual curves are not quite smooth there may be increasing of -r colprof parameter may required. But not likely for your device. It seems yours will be O.K.


Take a look at:

iccgamut -v -w -s a1.icc
(VRML viewer is needed).

Check dE2000:
profcheck -k -x -w -e a1.ti3 a1.icc

With colprof -S"" use -P parameter too. After computing the gamut mapping you'll got two VRML-files that shows the compression degree and directions.
Better use sRGB as the source space even your actual sources will be AdobeRGB. Some clipping is possible but you'll got less saturation loss due to gamut compression.

What is -P option? I can’t find it.
