In a printing apparatus, a carriage is reciprocally movable in first and second directions. A control device is configured to perform executing one of first and second printing operations in accordance with an operation mode. The first printing operation prints a first image over a first range in a third direction crossing the first and second directions by ejecting ink from both first and second heads during one movement of the carriage in the first and second directions. The second printing operation prints a second image over a second range narrower than the first range in the third direction by ejecting ink from both the first and second heads during the one movement of the carriage. Ink ejection contribution during the one movement of the carriage is shared by the first and second heads at a prescribed contribution ratio in the second printing operation.

The printing device includes a print head, a plurality of measuring members, and a controller. The print head is configured to print a patch chart on a print medium. The patch chart includes a plurality of patches including a plurality of first patches and one or more second patches. Each first patch has a predetermined color. Each second patch has a user specified color represented by an input color value. Each of the plurality of measuring members is configured to measure a color of a patch. The controller is configured to perform: a second-patch measurement process to control each of the plurality of measuring members to measure a color of each second patch to acquire a plurality of color values for the each second patch.

In a printing device, a head ejects ink on each of a plurality of printing media. Each of the plurality of printing media is classified into one of a plurality of media types. A control device acquires image data, and performs a halftone process to convert the image data to print data for controlling the head to eject the ink. The control device controls the head to eject the ink to print the image on the basis of the print data. Before the controlling, the control device acquires media information indicating, as an indicated media type, a media type from among the plurality of media types; and performs a decision process to decide a target conversion method from among a plurality of conversion methods on the basis of the indicated media type. The halftone process converts the image data to the print data according to the target conversion method.

A printing device comprises a head configured to print an image having a plurality of pixels on a printing medium based on image data, an input device configured to obtain an input of designating a pixel of the image, and a controller. The controller is configured to cause the printing device to print, on a same printing medium, a first patch group containing a plurality of patches, and a second patch group containing patches corresponding to the designated pixel designated via the input device, the second patch group containing a pair of patches, a color difference of the pair of patches contained in the second patch group being smaller than a color difference of a pair of patches with a smallest color difference among the plurality of patches contained in the first patch group.
