Problem packaging for printing

This is a pretty common issue with conversion from PageMaker.

Back "in the day" there were a couple of differing swatch libraries for Pantone colours in particular (CV vs CVC vs C, etc), and it was pretty common to have assets (liked a placed logo file that maybe you got from a diffrent client) that used one set while your PageMaker itself used another. This wasn't such a big deal back in the day as there were ways to deal with it, plus, if your were printing to process CMYK it didn't matter anyway. Swatch colours were based on CMYK values back then, unlike the colour-manged Lab values today.

Converting to InDesign it will see all the colours that were used in the PM file whether they were used or not. and even though Pantone Green CV is technically the same as Pantone Green CVC, ID sees each as Pantone Green despite the suffix, but still plays it safe and adds them as duplicates.

Stlil, if they aren't used it doesn't matter. When you Package, ID will list what Spot Colours are actually in use.

If you only see a list of the process colours, then NO spot colours are in use, despite being in your swatches. Also, again, if you are intending to print these all to process, it really doesn't matter in the end, as long as you tell your printer supplier that all spots are to be converted.

That being said, it would be nice now that you've converted the file to "clean it up" a little.

Easiest way to clean up your swatches is to go your Swatches panel, and pull down the top right options and Select All Unused. then delete any it selects, like in my example:

If you DO still have duplicate swatches, and you need to print spot colours, you can first try to delete one of the duplicates and replace it with the other.  This won't work if that colour is "locked" because it's being used in an asset (that logo file). You may have to reopen some of the old graphics and change your spots accordingly to be consistent. This would be a good approach going forward regardless.

If you can't do that for any reason, and still have a duplicate you can't get rid of, you can still instruct the printer to consolidate the duplicates when they output. Most Prepress departments have the ability to map spot colours together... It comes down to communication with your printer.

Hi @valentinf43688202 , Is the book printing via offset with extra plates for custom solid inks (Spot colors)?  Unless you intend to print extra color separations find the Spot colors in your Swatches panel and set their Color Type to Process. CMS off is referring to your Color Settings, with CMS turned off your color previews and any color conversion you make would be unreliable.

Without seeing the files there's no way for us to know where those colors are coming from.
