Author Topic: Saved "Print to File" looks posterized.  (Read 5107 times)

Okay, it's a bit slow in here so I thought I'd post something...

Did a "Print to File" after I did a very small correction in the QU editor.  Maybe 0.99 Blue, and a 0.97 Green to a TIFF image.  Only 1 point of contrast too.  Not much.  Did the "Print to File" and saved it as a TIFF.

When I opened the image in Windows Image Viewer and PS CS6, it looked very reddish in the blacks, and posterized (contrasty) too.  I noticed the image had been converted to 8 bits from the original 16 bits so I suspect something happened in there to cause the extreme difference?

Any ideas?

Not a big deal as I re-edited the original in CS6 by adding the magenta and slight warming for the yellow, but the QU "P-to-F" image really went wild!


Add:

I noticed when the P-to-F file went in to Photoshop it went as a "paper profile" from QU and not a generic "sRGB, Adobe 1998, or ProPhoto" profile.  I don't know if it should be set to maybe a Adobe 1998 RGB on the P-to-F save or not.  Does seem it went from 16 to 8 bit too so might explain some of the odd color and contrast when viewed in other image viewers than cannot figure out what "Epson Glossy.icm" (or icc?) is all about or how to handle it?

You can set the profile to what you want in the PTF dialogue.
See screen shot below.
A dot in "Monitor-Web" is always sRGB; a dot in "On-line printing or ...." has buttons for sRGB, Adobe RGB and browse to a profile of your choice.
Just follow the steps 1, 2 and 3.  Grin

It's bad enough that you people drive on the left, but do you have to do screen snaps in millimeters with decimals too?
