I could really use some help with this...
I'm getting a booklet ready to be printed. Originally, half of the pages were to be printed on paper with a (physical) colour. For budget reasons however, I've now decided to print the paper colour, and have the content of the pages overprinted on the tint in the background, which I've applied to the pages in the background of an additional master page.
When I set the objects to multiply, they blend with the background colour, which is the effect I'm looking for, as there would be no 'paper white' on the pages that I want to appear as though printed on coloured paper.
There's something confusing me though; you can also set the graphic within the object frame to multiply. This makes the graphic appear darker, which I don't really understand, since there is no extra colour within the graphic that accounts for this. I've looked at the output in the resulting pdf, and it looks like it's not just an on-screen effect, but the extra amount of (in this case) yellow would also be visible in the printed result.
Does anyone have an explanation for this? Please see the graphic for a visual example.
Thanks in advance, kind regards
