A method of determining one or more representative color encodings is disclosed. A set of color encoding clusters is determined for a plurality of candidate color encodings based on a clustering criterion related to one or more desired perceptual attributes of the plurality of candidate color encodings. Each candidate color encoding is assigned to one cluster within the set of color encoding clusters. A representative color encoding is determined for each cluster within the set of color encoding clusters depending on the candidate color encodings assigned to each cluster.

Colour encoding clustering

A method is disclosed where an initial placement of a watermark annotation on an output medium associated with a page and placement of an area of the page, is determined. The determined initial placement is relative to the output medium and independent of the placement of the area of the page. The initial placement of the watermark annotation is adjusted so that the watermark annotation at least partially overlaps the area of the page.
