Re: Printer profiling with densitometer only with PS

2005-05-18 by Louis Dina

Johnny, for occassional color work, I'd buy a color profile from 
somebody.  I think your procedure will take a lot of time and give 
you mediocre results, at best.  Scanner based profiling is not very 
accurate or satisfying in my experience.  I tried Monaco EZ Color a 
few years back and found it very lacking for good color printer 
profiles.  What you really need is a spectrophotometer and a good 
profiling package.
