Looking at various viewing light standards a while ago I remember the level
of light on the print ranging between 500 and 2000 Lux.  My viewing lights
put 1000 Lux on the print and my display brightness is 120 cd/m2.  

I've found that trying to match prints to displays is very sensitive
business... viewing light & display brightness, white points, surrounds,
ambient light levels, textures, gloss, viewing light spectrum, angles, paper
optical brighteners... they all play significant factors.


What rendering intent are you using when printing and what system are you
using for soft proofing?

Subject: [argyllcms] Recommendations to tweak ArgyllCMS profile to open up

Seasons greetings fellow ArgyllCMS users

Could someone provide recommendations on how to tweak the ArgyllCMS 
profiling process to open up shadows for printed output? Using Windows 
7, ArgyllCMS 1.6.3 and printing to a Canon IPF6350 with genuine OEM inks 
on various matte paper (Epson, Canon)

I have calibrated / profiled my dual monitor setup so they are a very 
close match to each other. The three-quarter-tones to shadow areas 
printed on matte paper are maybe 1 - 2 f-stops too dark compared to the 
screens. Printing the same image on photo glossy paper is much better 
(roughly 1/2 f-stop too dark in that region).

Results from ArgyllCMS / ColorMunki and ArgyllCMS / Pulse DTP20 printer 
profiles produce very similar results.
