Title: Re: matching paper white

I’m hoping someone can help me with the following problem.
I’m trying to tint the paper to match the white of the mat board. My issue is figuring out the exact, specific sequence to accomplish this without lots of trial and error.
I have created several test prints and things just don’t seem to come out the way I expect. With all the instrumentation available today, surely there’s got to be a simple and straight-forward way to accomplish this. I mean, what’s the point of all the multi-thousand dollar instruments, profiling software, etc., if color matching is still just trial and error?
Here’s what I did. Please correct me if I’m wrong:
1) Measure paper white of the mat board with a Spectrophotometer. I’m using the Spectrolino with Gretag Measure tool. For this particular mat board, I get LAB = (95.1, 0.6, -0..1)
2) Measure paper white of the print paper.. For this particular paper, I’m getting (91.4, 0.3, -1.9)
3) Determine the difference (paper – mat) = (-3.7, -0.3, 1.8)
Michael,
No mater what you do you can’t make your paper brighter than the mat board. You will never get the paper to match the white of the mat board. You could only match the mat board with a brighter papers (L*96 or higher) as you need to add ink to simulate the white of the reference which will invariably lower the L* after tinting.
