Title: Device Link transformation
Post by: anauta on February 16, 2010, 09:18:34 AM
Dear all,

I would very much appreciate it if QImage would support device link ICC profiles (as CS4 does).

Any chance of implementing it?

Thanks and greetings,
Auke Nauta

Auke,

What would you expect of device link support? 
Simulation of one RGB-Device on another one?
Or quality improvement that the normal CM processing doesn't deliver?

Dear Ernst,

I am looking for quality improvement.
For several printing systems I have created 3D-LUT's/device link's for superior performance.
Usually these are RGB->RGB transforms, sometimes RGB->CMYK.

Although I can easily perform the transform myself (I am a programmer) it would certainly be benificial to have it in QImage where I can enjoy numerous enhancement features, such as sharpening, scaling, etc...

Note that Photoshop (CS4) only performs devicelink conversion in the same colour space, i.e. RGB->RGB, but not RGB->CMYK :(

Thanks and best regards,
Auke

Auke,

Thought that CMYK would be mentioned. Given the RGB nature of Qimage I don't think you will get the last implanted. I can understand that it would open up more uses for Qimage than driving RGB devices. Though it will not replace a RIP on a CMYK-device.
