CMYK issues when printing black #4
Description
Hi,
I have noticed differences when printing with adobe and pdfium viewer, but I wanted to be more sure of what exactly I was seeing... so I tested... with a file with a 100% black background, and a 60% 40% 40% 100% CMYK text on it...
in Acrobat when you print it in black you don't see the text since the text is printed with black only too, so it disappears...
When you print in color in acrobat, the background is printed with Black toner, but the text is printed in CMYK.
Now, when I print in Pdfium viewer I already see a difference when I print in black... the black is lighter and more grained rasterized than the adobe print (aside from the print quality being not perfect). so it seems to be of less quality.
but when I print that same file in color, I would expect only the text to be printed with CMYK but now my full black (flat black) is also printed with CMYK toner giving it a blueish tint...
- how can I make it print so that it uses the toner just like adobe does? and is it at all possible?
- how do I get the raster to disappear from the print?
