Title: Print to file without embedding ICC Profile?
Post by: jzucker on August 02, 2012, 03:29:51 PM
I recently sent prints to WHCC and used qimage. My images have embedded Adobe RGB color space and qimage embedded my canon pixma pro 9000 MK II profile. The prints came out way too red.

WHCC says they are oversaturated and wants me to color-correct them and suggested removing the embedded icc profile.

How do I do that?

I will be most happy to tell you how to accomplish this, but I really don't quite understand.... Your images have embedded Adobe profiles, or they have embedded the printer profile.
If it is the latter, that your images have the Canon pixma profile embedded. Can fix that in a second.
If it has Adobe embedded and you want that fixed, a different operation.

PS what is WHCC?
If that is a commercial pronting house, what do they ask of you?

Hi
It's incorrect to embed your printer profile - the file will be specific to your printer only, and give different results on all other printers.
You will be OK if you choose  'Use sRGB and Disable Print Sharpening', you can always re-introduce sharpening before you click 'Print'.

I think that is your problem. If you images originally had Adobe RGB embedded and you left the Canon printer profile in place in Job Properties, then the image would be converted and that profile would end up being embedded in the image.
The print to File dialogue has 2 options: printer profile or sRGB. For a lab, the printer profile specified  and or supplied by the lab should be used in Job properties. If you want the image to end up with Adobe RGB, the put Adobe RGB  as the printer profile in the Job Properties. If that sounds strange, remember Print to File is "printing".
See Help, learn by example 25a.

Having said all that, if the lab is happy with an image in Adobe RGB and has that embedded, then why use Print to File?

WHCC tell you precisely what their requirements are with respect to colour management here:
http://www.whcc.com/resources/ordering-process/color-calibration-management/

Adobe RGB or sRGB; you supplied them with a Canon Pixma 9000 colour space and embedded.
I would say that if an image has a profile embedded, a proper colour managed printing process would cope with that and use the embedded profile - that what it's for!
