swatches don't merge when importing paragraph styles
When importing paragraph styles from the CC Library, the swatch colors for the styles get added to already existing swatches creating duplicates rather than merging. By the time all paragraph styles are added, there are 10+ swatches of the exact same color....
The PANTONE 540 CP swatch, when added in InDesign, is a CMYK ‘Process’ Color swatch – it comes from the PANTONE Color Bridge Coated library. This swatch was used in a Paragraph Style and this style was added to the CC Libraries.
You also created another swatch (a custom swatch) which has the same name – PANTONE 540 CP but it is a CMYK ‘Spot’ Color swatch. This was present in the document when the Paragraph Style (created above) was added from CC Libraries to the Paragraph Styles panel.
When the Paragraph Style was added from CC Libraries to the Paragraph Styles panel, it found that a swatch with the name “PANTONE 540 CP” already exists in the document. Since swatches with the same name but different definitions cannot exist together in a document, it added the incoming swatch with a different name – “PANTONE 540 CP 2” (to avoid name conflict).
Hope this is useful.
