In Colorsync Utility, what does the checkbox Softproof PDF/X Output Intent
exactly do? I mean, I do asume it converts all colors in a PDF/X document
to the Output Intent, but I mean from what exactly it is converting and how:
1. Does it still use Generic CMYK as **source** space for untagged CMYK
data (therefore performing a conversion from Generic CMYK to the Output
Intent, in which case, with what Rendering Intent), just like with any
other PDF? Or does it assume, when the checkbox is checked, that such data
is already in the Output Intent’s color space?
2. Once all colors are in the PDF/X Output Intent, what Rendering Intent is
it using then to convert them to my Monitor's color space?
Acrobat has checkboxes for "Simulate paper color" (which I asume means
Absolute Colorimetric; defaults to off) and "Simulate black ink" (which I
asume means Relative Colorimetric without Black Point Compensation;
defaults to off, which I guess is Perceptual/RC + BPC).
The fact that, in Colorsync Utility, whites remains white, but black is
washed out compared to Acrobat’s defaults lead me to think that it is using
Relative Colorimetric without Black Point Compensation. But if such is the
case, is it possible to convert using a Perceptual/Black Point
Compensation-like conversion instead?
