COLOR ANALYSIS

摘要

Techniques related to printing are described herein. According to an example, color patches are to be printed on a substrate. The substrate can be positioned on a substrate support for operation of a color sensor in a color measurement zone. Dimension and location in the substrate of the color patches are selected such that, for each color patch, at least a portion of the color patch can be positioned on a support projection in the color measurement zone. In some examples, color analysis techniques are described.

主权项

1. A printing system for printing a substrate, the printing system comprising:
a color measurement zone into which a color sensor is to determine color of color patches printed on the substrate; a substrate support for supporting the substrate at least in the color measurement zone during operation of the color sensor, the substrate support including
i) projections extending from a base of the support and arranged to support the substrate, andii) openings to allow deformation of the substrate towards the support base; and a test print engine to cause printing of the color patches on the substrate, the test print engine selecting dimension and location in the substrate of the color patches such that, for each color patch, at least a portion of the color patch can be positioned on a support projection in the color measurement zone when the substrate is positioned on the substrate support for operation of the color sensor.
