Acrobat changing colors unexpectedly

[leonardr]

You seem very knowledgeable about the workings of Adobe Acrobat

That's what happens when you are the Adobe's PDF Architect .

The issue at hand is spot color objects on individual pdf pages failing to appear when that page is added to a pdf not previously containing that specific spot color.

I would find it very helpful if you would outline likely causes of such an issue and provide possible solutions.

Happy to help, just need to know one thing...

What do you mean by "that page is added to a PDF"? Are you using Adobe Acrobat to insert a page from one document into another? Are you using Adobe Acrobat to overlay one page on top of another?

What is your EXACT WORKFLOW (what tools, versions, etc.) that are you doing that after it happens the color no longer appears?

Yes - "that page is added to a PDF" I am using the Acrobat 'Insert Page'

Say a booklet is a reprint. All the customer wants to change is the spot color of the duotone cover (i.e. from Reflex Blue & K to PANTONE Green & K). So I might use the Acrobat 'Replace Page' to insert the new cover page with its new color into the previous pdf. This issue is not workflow specific because it takes place while creating a pdf prior to the RIP.

We do have Enfocus Pitstop plug-in installed, but no other special tools.

Replace Pages does what the name implies - it takes the page CONTENT from one page and drops it in place of another. Should work just fine.

One alternative is to Insert Pages (on the new page) and then Delete Pages (on the old one). It's a bit more "brute force" than Replace but sometimes that's necessary.
