Re: Linearization - mathematical or perceptual?

2004-04-26 by Peter

Thank you to everyone who replied to my message -- this is exactly 
the discussion I was hoping for. 

For a variety of reasons I've decided that I'm not prepared for all 
the control a RIP will provide, but I'd still like the ability to 
tweak an existing profile to account for variances in paper batches 
or the unique characteristics of my printer, for example. About a 
year and a half ago I used the Curves Template located in the Files 
section 
(http://groups.yahoo.com/group/DigitalBlackandWhiteThePrint/files/Ima
ge%20Processing/) to create a Photoshop adjustment layer but I 
believe this spreadsheet does a strictly mathematical linearization.

I'm hoping to do something similar (i.e. measure the density values 
in a stepwedge, compare to some Aims and make an adjustment curve) 
but would like to account for perceptual issues. I'll see what I can 
figure out with the Bruce Lindbloom calculators.

Thanks again for your insight (and if you have any hints, I'm all 
ears!).

Peter.
