Spot colours – specific inks applied to blocks of type or graphics – have their own plates. Any spot colours defined within a document but not used should be deleted to ensure plates. Any spot colours defined within a document but not used should be deleted to ensure plates are not generated unnecessarily. In the past, the names given to spot colours within software were not significant, since the designer would brief the printer on the inks to be used. Increasing automation makes it advisable to stick to the naming conventions of an ink library such as PANTONE. If images or artwork containing spot colours are imported into DTP software from other programs, the colour names must be an exact match to those set up in your layout, or elements in the ‘same’ colour will appear on different platrs.
