Flattened by Transparency Flattening issues.

[R***@adobeforums.com]

Hello all,

I have an ad in InDesign and when I tried to export to PDF I got the following rather unpleasant message:

"The document's transparency blend space doesn't match the destination color space specified in Export Adobe PDF settings. To avoid color appearance changes in PDF settings, click cancel and change either the document's transparancy blend space, or the destination color space..."

Indeed, I lost a color when I looked at the PDF. Ugh!

If this is an Acrobat issue rather than a InDesign issue please forgive, let me know, and I'll go try that message board.

Cheers,
RP.

I suspect you are working in RGB and exporting to CMYK, and the loss of color is more likely a result of the smaller gamut and generally less bright colors obtainable on press.

My understanding has been that the transparency blend space should reflect the color space in which you are working, but if you are mixing rgb images and cmyk native elements, I think you might want to move into the cmyk space, but I'll let someone else with more flattening experience, perhaps Dov is watching, offer a better opinion/explanation.

Hello Peter and board,

I have a grayscale image where I have done the spot-blue thing (dragged and dropped our official company pantone blue from the swatch palette) then I put a box with the same blue on it but did the transparency thing and made the opacity 47% or so. Then I put a text box on it with, um, some text. Then I export to PDF/X-1a:2001 and my transparency box becomes a white square in the PDF. I was rather unpleased at this revolting development.

FYI I'm running Windows XP and CS2.

Cheers,
RP.

But...

Why use transparency at all? Aren't you really just trying to make that box a 47% tint?

Lots of people confuse transparency with tints because they both use the word "Opacity" to describe what is going on. If you want something to show through, or you need a special blending mode, you need transparency. If you just want a lighter color you want a tint, which you get by adjusting the opacity slider in the swatches palette.

If you put the box in front of the logo and made it transparent so the logo would show through, move the box behind the logo and change it to a tint.

No need to make your life, or your document more complicated than necessary.

Peter,

That works too--and I just love these forums because my arsenal of knowledge just keeps buffing up. Thanks!

Robert,

I've book marked that site and will explore it tomorrow morning over a cup of coffee

Cheers,
