With papers changing the way they are; most do not fall within the
tolerances specified in 12647-2. I like this idea of the Substrate
Calculator. My question is this. Let's say we proof to GRACoL tolerances
on a paper that is within the specification. We now get a #1 or #2 paper
that is out of spec. I use the calculator, create a new CGATS file and
create a new ICC Profile. I use CGS ORIS Color Tuner and hone in my
proofing device (Indigo press) to within tolerance and proof my
files/images on the "new" paper. What have I achieved. I have created a
proof that the printer may have an easier time "matching"; but can I say
that this proof adheres to GRACoL specifications? If you were to read the
12647 color bar it would pass only if I have the proper dataset loaded to
compare to using software such as ORIS Certified Proof. Someone else
checking my proof to GRACoL would say it "fails" because they would be
comparing to the "original GRACoL". What exactly have I accomplished and
how can it be classified as a specification.
