Hi Kevin,
The "quick" method I use, if a customer is asking me to profile a paper
I'm not familiar with, is to print a "raw" (unlimited) CMYK step wedge
and measure to see what the maximum *chroma* (Lch) values the paper is
able to achieve (for K simply measure the Dmax). Compare this to the
paper you're currently happy with and see if the chroma values meet or
exceed your expectations.
Assuming it meets some sort of minimum standard, the more important
issue would be the consistency of the paper from batch-to-batch. See if
the vendor will commit to a minimum delta e variance from roll-to-roll.
Most high quality paper vendors will guarantee no more than 2 delta e
difference from roll-to-roll.
OR see if the vendor will PAY YOU to test their paper to have a crack
at your paper business. They need to realize that changing inkjet
proofing papers is NOT a trivial thing and can easily take 1-2 days to
get it calibrated/profiled just right.
You're in Asheville, eh? I'm over in Charlotte. We should meet sometime
as soon I can get myself off the road for a while! It's been so bad
lately that my wife and 3 kids drove up from Charlotte to Akron OH last
weekend (I drove down from MI) just so we could see each other in the
midst of my current 2-3 week "tour-of-duty"! :-)
Later,
Terry "The Color Road Warrior" Wyse

Quick Paper Evaluation Procedure
We are often approached by salesmen from paper companies who claim that
their Ink Jet paper is cheaper, better, etc. Now, for all I know, their
claims may be absolutely true! But, in the middle of a production
environment, I find it difficult to set aside half of my day to ink
limit, linerize and profile the free paper sample that these guys want
me to 'try out'. I imagine I'm not the only one.
So, I wanted to open up a discussion as to possible methods for quickly
determining the LIKELY color reproduction capabilities of media. In
other words, to quickly determine if the media is WORTH THE TIME to
begin the process of tuning in the color.
