PCL and CMYK

[scvalley]

Hello,

I am new here so please bear with me if my question has been posted somewhere.

I have a CMYK image file (i.e. 4 color components / pixel) and I am trying to find out what is the command in PCL6 to define the image data in CMYK color space and how to tell the printer that every pixel has has 4 components. I checked SetColorSpace operation. But this operation only take 2 values, i.e. eRGB and eGray. How to do with CMYK image then? Am I looking at the wrong operation or was this operation extended but I am not aware of?

BTW, I also checked PCL 5c. But PCL5c only supports CMY, i.e. for each pixel, PCL5c can only deliver 3 components. Am I correct?

Thanks in advance.

As far as I can see, for PCL XL, even at Protocol class/revision 3.0, the ColorSpace attribute only has two allowed values (1=eGray; 2=eRGB).

For PCL5, I think that some devices (perhaps only some of the larger DesignJets?) had an allowed value of 4 (meaning "4 planes, device KCMY palette") with the 'Simple Colour' escape sequence ({esc}*r#U).
