    Hi

    I have a wonderful photo with a bright blue sky and a building with bright orange brickwork which I want to use for the cover of a sales brochure. When I place it into Indesign CS4 it looks good. The moment I put a psd logo on it with transparency the bright blue and orange dull.

    I've read these items: https://creativepro.com/my-…..ddenly.php and https://creativepro.com/for…..mp;ret=all

    – and if I change the transparency blend space to document RGB the bright colours return. However, when I export as pdf to create an flipbook, I can't seem to figure out how to retain these colours – they go dull again. Are there some pdf setting available to achieve this?

    Also, if I wanted to get a job lot of these printed with a commercial printers using a document exported to pdf/x1a are the dull colours as displayed in the pdf, and not the bright colours, printed? If so, this would be a real shame.

    Thanks.

    Check your PDF export color conversion — the colors are probably converted to CMYK at that point.

    Ask if he accepts PDFs in RGB color space. If so, his printer may have an internal RGB-to-CMYK conversion, which usually is much better than InDesign's, because it can use the full technical capabilities of that particular printer and its ink or toner.

    (But the colors won't ever be as bright as they appear on screen. The screen is a lamp and emits light, where paper only reflects it.)
