I have a pdf file in Acrobat, and I can check that it has multiple colour separations ( i.e. CMYK and PMS 123 and PMS 321)
When I try to open it in Photoshop it asks to converts the pdf in RGB/CMYK/CieLab/...whatever, but you can not view the native numbers of colours.
Is it possible to open it in Photoshop and view the number of colours/channels as if I saw it on Acrobat??
Anyone can help me on this?
As far as i can tell this is not possible in Photoshop.
You might be able to print a separated pdf in Acrobat, then convert that and combine the Channels in Photoshop.
