Document's transparency blend space? Destination color space?

I need some hand-holding please.

I just exported to pdf, and got this message, and would be happy to fix it if I had a clue what to do:

The document's transparency blend space doesn't match the destination color space specified in the Export Adobe PDF settings.

To avoid color appearance changes in the PDF, click cancel and change either the document's transparency blend space, or the destination color space.

Can you please translate that into English and tell me what to do?

I finally solved my problem by going to File: Adobe PDF Presets; Choose which preset you want; Click the "Output" tab; Change "Destination" to Document CMYK - U.S. Web Coated. Worked for me.

Just an FYI... if you get this warning, check if you have PDF's placed in the document. A coworker was getting this warning and we tracked it down to PDF's placed into the Indesign file and those PDF's had transparencies.

Once those PDF's were removed from the file the warning went away and she was able to save the PDF.

This is the answer. It makes the transparency color spaces match. Nicely done!

OK, I've reproduced the problem, and here's what I'd do.

You've placed RGB images over CMYK vector paterns made in Illustrator, which in some ways makes things more complex than if the imges and backgrounds were all in a single color space, but it looks as if only the backgrounds are going to be affected by any flattening that will be taking place in the conversion, so if there is any color shifting due to the flattening and choice of space, and I don't see any, it will be isolated to the background texture and probably not noticeable.

Since you have two destinations, you need two differnt PDFs. The sample is very interesting, but I suspect the print run will be small -- limited to family members -- so the first thing to do is ask the printer what PDF export settings he wants you to use. If you're going to have this printed somewhere like Kinkos or Staples, they probably can't answer that question, and I'd stick with the High Quality Print preset, and be sure the compatibility is set to Acrobat 5 or higher so the transparency isn't flattened. Print one page as a sample before committing to the entire job to check the color (and don't expect miracles from the average copy shop running a color copier -- they usually just aren't set up to handle color management and matching).

For the screen version, set the blend space to RGB and choose the Smallest File Size preset. you shouldn't get the warning (but you could ignore it even if you did). If the file is still too big, set the compressin settings to downsample color and grayscale to 75 ppi and lineart to 600 and see if that helps before you try reducing the quality in the compression. The prints off a desktop printer won't be quite as good as they will be at 100ppi, but probably acceptable on most inexpensive paper stocks that peopl seem to use, and hopefully they are going to get the better printed version, anyway.

Hi Peter -

Thanks for all the details -

My sister made the CMYK vector patterns for me in Illustrator; I don't know anything about Illlustrator at all (and can just get by in InDesign!).... truthfully, I'm tempted to just remove the background color swatches if they're causing troubles!

For the High Quality, I wasn't getting an error message. My aunt is paying for this and has selected a web-based (ie, very very cheap) printing company. I play to have one 'proof' printed to see if it meets her expectations.

For the Screen version, I have been setting the Blend Space to RGB and choosing the smallest file size; you say I should not get the warning. I have been getting the warning - that was the problem. But, now that you say I can ignore it, I will GLADLY ignore it. On the level of: it isn't a problem until it's a problem.

You're right - we're talking about 6-25 copies. The idea is that I'll post it at the web, to get a sense from relatives whether or not they want hard copy. If/when we tell folks it's a photo album, they don't want it. When they realize it has dates and names and stories and info, they are more interested.

Thank you so much - I'll follow your advice on the downsampling and be back if I have more trouble.

Any color shifting due to the flattener space is going to be minor compared to shifting due to a profile mismatch at the printing company, or just plain out-of-calibration equipment. Unless the color fidelity of that background is absolutley critical I wouldn't give it a second thought, and if it is, I'd print locally where you have a better chance of getting what you want without a major hassle.

Most likely you've picked a CMYK destination, but the Blend space is set to Document RGB. Switch it to CMYK.

Peter.... I really appreciate your help, but I don't know what a CMYK destination is, where I might have picked one, what a Blend Space is, or where I might have set a Blend Space to Document RGB....

Can you point me where I can change my Blend Space?
