    Abstract: In one example of the disclosure, a first area of an image to be printed at a first gloss level is identified. A second area of the image to be printed at a lesser second gloss level is identified. Printing of the image is caused in a gloss-varying printmode that applies a pretreatment fluid to a media where the second area is to be printed, and not where the first area is to be printed, and applies a colorant or colorants to the media where the first and second areas are to be printed.

    Abstract: A printer is disclosed. The printer is calibrated for use with colored media. The printer is calibrated by converting an original color look up table (CLUT) for use on any colored media to a modified CLUT for use on colored media with a measured color. Each of a plurality of output colors in the original CLUT are modified using the measured color of the media.

    Abstract: In one implementation, an example print apparatus includes a fluid ejection system operated by control instructions generated from a print engine and a compensation engine. The compensation engine determines an amount of the auxiliary colorant fluid to produce a combination of the base colorant fluid and the auxiliary colorant fluid based on input color image data, a reflective quality of a substrate to be printed on, and an opacity grade of the base colorant fluid. The print engine generates control instructions to instruct the fluid ejection system to print the combination of the base colorant fluid and the auxiliary colorant fluid on the substrate.

    Abstract: A method in a printer comprising a first printhead to dispense a first printing fluid and a second printhead to dispense a second printing fluid, the first and second printheads being arranged on a common scan axis that is substantially perpendicular to a media advance direction. The method comprises controlling movement of the first and second printheads relative to a media being printed, between a first index position and a second index position, the second index position being downstream of the first index position, and wherein the movement occurs during a time period between a forward scan and a reverse scan of the first and second printheads across a media being printed.
