Hello,
I was hoping some on the list here could help shed some light on just
how the Adobe CS suite handles its Pantone Spot libraries. It is my
understanding (and I may well be wrong) that Photoshop CS bases its
Pantone colors off of the LAB definitions supplied to Adobe by Pantone.
The RGB or CMYK breakdowns are then generated based on the documents
ICC profile.
I am unclear however on how Illustrator/InDesign handle Pantone colors.
My hope was that the three apps used the same methodology to derive the
RGB and CMYK breakdowns, but apparently this is not the case. I have
read on the Adobe forums that Illustrator and InDesign base their
values from the CMYK breakdowns supplied from Pantone, not the LAB
values. This seems to make sense from what I've observed, because no
matter what CMYK profile I assign a document, the Pantone breakdowns
are always the same. But for RGB documents, the breakdowns vary
depending on the document profile.
So it seems that for CMYK documents Illustrator and InDesign always use
the Pantone blessed values, but for RGB documents, these CMYK value get
converted to the RGB space assigned to the document. If this is the
case, does anyone know what the source space for the blessed Pantones
are, and how it is getting converted to RGB?
