A method for color mapping is disclosed based on obtaining a measurement of one or more characteristics of an imaging system. A set of color mappings are provided and the color mapping is selected based on the measurement. Each of the color mappings enables a mapping from a first color space to Neugebauer Primary area coverage vector space. A method for generating a color mapping is disclosed.

Color mapping

According to one example, there is provided a method of determining an alignment characteristic of a printhead die installed in a printer. The method comprises controlling the printer to print a predetermined pattern using the printhead die and determining, through analysis of the distance between features of the printed predetermined pattern, alignment characteristics of the printhead die.

Determining an alignment characteristic based on distances of features of a printed pattern

A method for reducing vertical banding of a printed image, the method performed by a control system associated with a printer, the method includes, with the control system, adjusting the spacing between which ink droplets are fired from ink nozzles of the printer as the ink nozzles move in relation to a substrate. A printing apparatus includes a platen and a carriage including a number of ink nozzles, the carriage being configured to move across a substrate placed on top of the platen; and a control system configured to adjust the spacing between which ink droplets are fired from ink nozzles of the printer as the ink nozzles move in relation to a substrate.
