"Saturation" versus "Perceptual" rendering intent -- problems with yellow

2007-11-14 by nealdryan

Using Spyder3Print with my new PrintFixPro I made a 255 color ICC 
profile for my HP B9180 and Epson Premium Presentation Paper Matte.

I then tested it using Bill Atkinson's LAB color test image in 
the "Profile Test Images archive here: 
http://homepage.mac.com/billatkinson/FileSharing2.html

On all the profiles that come with the B9180, when I soft proof in 
CS3, the perceptual and the saturation rendering intents give 
essentially the screen display (which look great) and they print 
very well and very much like the soft proof displays.

On the profile I made with PrintFixPro the bright yellows 
(especially around the sun in the sunset picture at the lower left 
but all yellows in other parts too) are muddy and have lots of black 
in them on perceptual and look good on saturation intent. And the 
prints look just like the soft proof--unusably muddy on the yellow 
colors with perceptual rendering.

You guys off course recomend saturation and not perceptual intent on 
rendering and that works fine for CS3.  Unfortunately I do almost 
all my printing with Lightroom which doesn't give me a choice of 
saturation -- it's perceptual or relative only as rendering intent 
with Lightroom.

Help!
