I posted this question on the Illustrator forum. However, we haven't got much further than square 1 so far! Since this is also relevant in Photoshop, I thought perhaps some folks here could chime in on the topic.
Well, in all that mumbo-jumbo in your other thread neither of the participants are considering Gamma or that using color profiles are also applied per component, meaning that each channel could have totally different numerical results compared to a linear blending operation plus then of course there will always be quantization issues in 8bpc and 16bpc further skewing results.
Well, in all fairness, I did mention colour profiles. Would you be able to walk us through the example that I had provided in the original post? Or perhaps the same example in Photoshop and you can point out and add any information that might be missing from my post.
I haven't really gone much into CMYK blend mode behavior. But as always, I expect the K channel messes up any nice, predictable behavior. The K channel isn't really a color component, just a pasted-on aid to the printing process.
But as for the Blend Mode Multiply that should not be relevant in as much as the results are calculated Channel for Channel and not based on the composite appearance as far as I know. (edited)
That's true, and obviously the numbers behave in a predictable way. I was more concerned that the visual appearance may not be what you expected given the special characteristics of the K channel.
But as I said I haven't really gone into this. Just thought I'd throw it out -
