Hi,

I have a div with a grey background color, its CMYK value is (0,0,0,20).

It seems that prince have a little trouble with it, because the outputed color is nearly black and miles away from the estimated color. Also cmyk(100,100,100,20) does not work properly.

If I set something like cmyk(20,20,20,20) it works perfect.

So is there any probem, when only set the black value in CMYK?

The numbers need to be between 0 and 1, so how about trying cmyk(0,0,0,0.2) ?

Yeay, works perfect!

Sorry my fault. Thanks Mike.
