I've created some graphics on Adobe Illustrator and have saved them as a pdf. Using Output preview/Object Inspector (from the dropdown Preview list) I can check that every object in the the graphics have a color of C=100 M=100 Y=100 K=0 as I designed and that no color conversion has been done. So the colors on this pdf are correct.
Now I'd like to print it this way. When I tried to do this, I could see by eye, in the print result, that the only black had been used (something like C=0 M=0 Y=0 K=100). Then, I tried to print from this correct pdf to another pdf, selecting 'Adobe PDF' as the printer! With this test I saw, with Object Inspector, that the color had been converted to RGB, and that the combination is now somehting like (R=21 G=21 B=23).
I know the two issues might be unrelated, but: What can I do to have my printer print C=100 M=100 Y=100 K=0 without any conversions, printing CMY toners as strong as it can? (I'm using Samsung CLP-315 laser printer, btw)
I want this because my black toner has the flu and is printing unevenly.
