Re: Creating an icc profile with a densiometer.

2018-09-06 by per@...

Thanks for your detailed answer Brian. I am finally getting around to testing this flow. Here are two questions:

1. When I print my test picture to measure, why is it necessary to convert to adobeRGB from the assigned gray 2.2? I understand that you have to force photoshop to think the picture is already in sRGB, but what does the conversion from gray 2.2 to adobeRGB do?

2. Assume I followed the flow to print a test ramp without ICC and created an ICC profile from the result. If I now wanted to check that the same ramp now is linear after correction, would I 1) load the untagged ramp, 2) assigning it gray gamma 2.2, 3) converting it to my ICC profile, 3) assigning it srgb, 4) print? Or does there have to be a conversion to adobeRGB too in there somewhere?

Kind regards,
