but nonetheless there does seem to be a problem with Photoshop because even with the color profile properly emedded/attached to an. in this case, the grayscale issue is completely resolved! The grayscales appear in Photoshop exactly as they did in Illustrator!!!įrom a functional perspective, my problem is resolved, because I am able to get TIFFS that look the way they should.
#Ai to photoshop pdf#
AI file into directly into Photoshop, and that's where the rasterizing occurred.Ģ) Per your above, I have attempted to export a PDF, paying careful attention to "no color conversion", and "include profile", and yet the same problem grayscale shift persists once the PDF is imported into Photoshop, where again the rasterizing occurs.ģ) *** However, if per your other suggestion above, I instead attempt to bypass the PDF step (which I had never been doing anyways) and export the vector drawing from Illustrator by saving directly into TIFF/PSD from Illustrator. the colors are not shifting, only the grays!įurthermore, I have discovered one additional clue:ġ) I had never previously attempted to export a PDF. On further consideration, I think however you may have touched a nerve. In my mind, all should remain the same if the color space is being preserved, so grayscale is sufficient to prove that the color management is broken.
OK, now I hear you about the distinction between color versus grayscale shift. Quitting and restarting Photoshot would appear to "re-set" the color reading of the thumbnail preview to the correct/AI appearance of the greys. ai file a second time, this time the thumbnail preview displays the greys incorrectly (relative to the ai file), whereas the first time, as per above, the preview was correct. if, now, I should attempt again to rasterize the same. the greys are different once Photoshop delivers the result > the same one as in Illustrator, namely sRBG IE61966-2.1 >Īnd yet. and, as you can see, the color profile selected is CORRECT, ie. ai file in Photoshop, per below PS screenshot, the thumbnail preview displays the image correctly, at least in so far as the relative appearance and contrast of the greys. To give some additional head-scratching, consider the following in careful detail. Per below AI screenshot, I have color settings synchronized by default, and the Color Settings in AI of the files in question has the color space set to > sRBG IE61966-2.1 // which is the same color space I am using in attempting to rasterize via Photoshop But still, as I said, grayscale is a can of worms and a headache. If Illustrator had the same grayscale support as Photoshop, I don't think this would have happened. Not to mention that it's impossible to know how grayscale is handled internally in Ai, what tone response curve is used.
But a conversion from CMYK to grayscale is not the same as a conversion from the K channel alone, into grayscale. Illustrator exports grayscale elements as 0-0-0-K (I think - at least I know InDesign does it that way). I suspect the wild card here is the grayscale element. In fact color management is all about recalculating numbers to preserve color. You only get into trouble if you pick color by numbers - which will render differently in different color spaces. That is indeed the whole point of color management. And assuming everything's in gamut, everything should display identically even if you have different color spaces. I should be able to pick any color that is available to me on the color swatch and that color should appear the same in Photoshop after rasterizing, otherwise what's the point of color management? So I humbly disagree with c.pfaffenbichler's somewhat arrogant statement that there is "nothing Adobe need address with regard to my problem".
A color is a color, and a given color should appear the same from one platform to the other, within the same color space. To the extent I am working within the same color space in both AI and PS, I should be able to pick any color that is available to me and that color should appear the same in Photoshop after rasterizing, otherwise what's the point of color management? It should not be this complicated. It is news to me that I have to concern myself with picking "RGB colors" versus "CMYK colors" or "Grayscale colors" when picking colors from a color wheel or a palette of available colors in AI. Just to clarify, the file I posted with the grey ellipses is just an example. Apologize to all for the frustration resulting from a parallel thread - rest assured it is almost matched by my own frustration at the original thread being abandoned! Thanks to all for these additional insights.
