Source profiles that don’t match Warning (even after deleting ALL the images!!!)

Hi, I'm ready to upload an InDesign project with Blurb plugin. So, I try to export a test-PDF in Blurb preset, but InDesign reports a warning: «The preset specifies source profiles that don’t match the current color settings file. Profiles specified by the current color setting will be used».

I can say that ALL the images have been previously converted into Blurb CMYK profile (in Photoshop). The strange thing is that even deleting ALL the images (keeping only text), InDesign still reports the same warning!!!

Is it a Poltergeist phenomenon?

Thanks in advance.

(P.S. As always Blurb's support can't say...)

...Also, in Adobe Bridge, the preflight-PDF is reported as Color Profile UNTAGGED! How is it possible?

Color Settings are your color preferences for new documents, they wouldn't normally color manage an existing document. For existing documents check Edit>Assign Profiles..., which will show the RGB and CMYK profiles assigned to the document.

PDFs can have any number of objects with different color spaces and embedded profiles. PDF/X exports include an Output Intent CMYK profile, and all CMYK objects with matching profiles export as DeviceCMYK (no embedded profile).

Also, if you are exporting to PDF/X-3, with No Color Coversion, which I think is Blurb's recommendation, you can check the exported CMYK Separation values in AcrobatPro's Output Preview.

if I see my images in Adobe Bridge there is written Blurb_ICC_Profile.icc. Instead, in ID's Links panel I find a generic “Document CMYK”... Where is the spec that reports the profile?

When you create a document with the Color Settings CMYK CM Policy set to Preserve Numbers (Ignore Linked Profiles) the profile listed in Links will be Document CMYK--the document's assigned profile is being used to colormanage the link.

Dear Rob, thanks for your reply.

The point is that I don't export any PDF file. Since I use Blurb's plugin in ID, I simply upload the ID project itself. (So - you could tell - you can easily ignore the warning.) The problem is that when I try to upload the ID project via Blurb's plugin, also the plugin itself reports the same warning! Also, the strange thing is that even when ID doesn't report any warning, Blurb's plugin surely does!

My point is simply avoiding a new re-conversion made by Blurb...
(You'll say «ask to Blurb»... Yeah... Blurb is a modern oracle...)

Can you post a capture of Blurb's warning?

Also, what are the document's assigned profiles (Edit>Assign Profiles..., not Color Settings' Working spaces)?

This has come up a number of times and Peter is right, you can ignore the warning. I'm traveling so I can't post captures, but if it's the warning that shows in the Export setup dialog, it happens when the InDesign document's assigned RGB and CMYK profiles are not the default sRGB and US Web Coated SWOP--you could get the warning in a document with no placed images.

Obviously there are many cases where the default profiles should not be used--I would never use sRGB for a print project--so if it is the same warning, it can be ignored.

You might want to post a capture so we can confirm.

In general that warning can be ignored. It generally happens becasue the preset is based on something generic and customized. The settings may specify color settings that differ from the profile that Blurb wants you to use.

Thanks Peter for your reply.

My doubt is: you say I can ignore it, but that warning should say that my images will be re-converted to match the Blurb's profile (that ironically they have yet!) And I really don't want my images will be reconverted!
This problem is not directly my problem, since I upload the project with Blurb's plugin directly to Blurb's cloud. But the problem could be later: once Blurb will receive the file, that warning could imply an antomatic (and unnecessary) re-conversion. Is that right?

NO. It says YOUR settings, not the ones in the preset, will be used, which is exactly what you want, if you are using the correct profiles. Remember, these are SOURCE profiles, not destination, so all it means is you've used different profiles than the preset expected, but they will be respected and used.

I see this warning every time I export a PDF for print.

Crazy update: I tried to export a new file with a single EMPTY page (Color settings on Blurb)... same warning appears!!!

It should be the well known Blurb's Poltergeist phenomenon...

Your color settings may be part of your document, but they're independent of your document.

Color settings are metadata — kind of a structural definition behind your InDesign document — that explains how to adapt color values and apply color management standards and rules for your document output. They are applied whenever you open any document, independent of the graphic elements you place into it.

You can learn more about color management here. If you're inclined, follow some of the links on this help page to learn a lot about InDesign color management, and why it's done. And also, how to tailor it for specific purposes like creating digital documents.

Hope this helps,

Randy

Randy thanks for your reply and for the link.

Perhaps it's me, but this doesn't give an answer to my problem. Or at least not an operative answer.

In few words: what should I do?

Thanks
