I understand where your coming from, from a purists point of view I agree but
from a rationalist point of view I feel profiling every paper stock and having to
manager all the incurring profiles is over kill. Now before I get banished from
the list and forbidden to use profiles again hear me out. If I do a great job at
making and tuning the initial profile to emulate a conventional proofing
(Waterproof) system would you agree that the profile I have made is a good
description of that color system, including paper. Now if I change paper on my
conventional proofing system, color will change according to the cast of the
paper. Your assumptions lead one to think that if I use my Waterproof Profile,
color will move significantly different for the profile generated proof than the
conventionally generated proof. The purist will say yes, but what practical
application has proven is that the paper cast tends to move the profile generated
proof in the same direction as the as the conventional proof. The key is to start
with a good white stock to make the initial profile. When going to digital dot
proofers like the Approval stay with device link profiles.
Now I do make profiles for different line screens, for imaging to paper or
transfer sheet and if paper stock is significantly different (like news print)
then I'll make a new profile, but I've used my standard Waterproof transfer sheet
profile on all kinds of stock with great press results.
Maybe I'm living dangerously.
