Hello to all,<br>
<br>
Reading the discussion about print targets, i missed some points:<br>
<br>
1) CMYK Colorspace for profiling Gutenprint:<br>
I strongly recommend to profile CMYK+X printers only with CMYK (+X) targets. Dealing with the relation of CMY to K is much better handled inside the printer ICC profile, than with a internal Gutenprint RGB_to_CMYK conversion and an RGB-printer-profile on the top.<br>
<br></blockquote><div><br></div><div>This is an interesting remark. At the moment, we have working presets for some printers, and an internal working though not perfect RGB => CMYK conversions for Gutenprint; Historically RGB was sent better through CUPS. I suggest that we start with an RGB print path. Note also that Linux apps are not very good at separating to CMYK by a profile usually :) so for prototyping I think RGB is really the only choice, not because it is better or even as good, but just because we can. </div>
