InDesign CS 2: Phantom Spot Colors

If I knew what caused it, I would know how to prevent it. Suspicions include placing a .ai or .eps graphic that contains a spot color. Or a pdf. Or copying and pasting such an object from one InDesign file to another–even when the spot color exists in both documents.

But at the point when I am preparing the file for final release, I often discover one or more colors I cannot modify or delete.

This annoys me primarily because I am the sort of production artist who prefers to delete all unnecessary colors, fonts, layers, objects, etc. from a file. The impact of such detritus on today’s modern RIPs (modern enough, shall we establish, to handle InDesign CS2 files to begin with) is likely insignificant at this point in the technology. But to me this kind of manual file scrubbing remains both a valuable idiot-proofing practice and a matter of common courtesy–towards my own self or some other designer or production artist who will be asked to adapt this file for reprinting in three to six months time.

But this is not merely a matter of my own work habits and hangups.

Often I am handed a file in which a designer has created swatches for dozens, if not hundreds of PANTONE swatch colors, and I must select each color individually (or in small batches) to winnow down the list to the set of colors in actual use. (The workaround in which I create a new mechanical document, and copy and paste objects from the designer document into my new one can often compound the problem of these phantom spot colors–turning previously editable colors into the undead.)

One trick I have found success with is exporting the file as an InDesign Interchange document (.inx), and then re-importing it into InDesign. Be sure to clean up your placed graphics (e.g. convert spot colors to process as needed) before you do this step, or you may find yourself doing it more than once.
