Endpapers use correct colours
This check is making sure that the spot colours used in ENDPAPERS are matching the expectations required by your publisher.
‘Spot Colours’ are used to add to the CMYK print process and can be used to add eye-catching extra inks and special finishes such as foils and varnishes. They can also be used to indicate physical production techniques such as cutter guides and embossing.
The use of the PANTONE colour library is required for inks that are not made from the CMYK process colours. The Pantone colour reference should be explicit in the spot colour name. The easiest way to do this is to use the assigned colour name when adding a spot colour.
Spot colours used in others apps such as Photoshop and Illustrator are OK to use. They should also use the same PANTONE naming.
Other special finishes are not permitted in endpapers so no other spot colours apart from PANTONES can also be used.
