Apparatus and non-transitory computer-readable medium

摘要

An apparatus includes a memory storing computer-readable instructions to cause the apparatus to perform determining a scanning number of times. The scanning number of times is a number of times that a carriage of a printer is to be moved to increase a maximum density of a first ink to be higher than a unit density. The instructions also cause the apparatus to perform generating print data to cause ejection of the first and a second ink by multi-pass scans in a final printing unit. The final printing unit is continuous scans corresponding to a number of passes including a last scan, among the scans to be performed the scanning number of times. The second ink is an ink whose density is equal to or less than the unit density, among the different inks.

1. An apparatus comprising:
a control portion; and a non-transitory memory configured to store computer-readable instructions that, when executed by the control portion, cause the apparatus to perform the steps of:
determining a scanning number of times being a number of times that a printer carriage mounting a plurality of ink heads thereon is to be moved in a main scanning direction to form a single line image formed by a single dot array extending in the main scanning direction and having a width, in a sub scanning direction orthogonal to the main scanning direction, corresponding to a size of a nozzle formed in the ink head and to increase a maximum density of a first ink in the single line image to be higher than a unit density by ejecting the first ink a plurality of times to the single dot array, the printer carriage being provided in a printer, the plurality of ink heads having at least one first ink head configured to eject the first ink and at least one second ink head configured to eject a second ink, the one first ink head and the one second ink head being aligned along the sub scanning direction, the unit density being a density of a maximum amount of ink that can be ejected by moving the carriage once with respect to a single dot array; and generating, in a case where the scanning number of times is larger than a minimum value of a number of passes that can be set as a number of times of scans of a set of multi-pass scans, print data to cause ejection of the first ink and ejection of a second ink to be performed by the multi-pass scans in a final printing unit, among a plurality of scans to be performed a plurality of times equal to the scanning number of times, the set of multi-pass scans being a set of a plurality of scans in which, every time a scan is performed, an ink is ejected to the single dot array from a nozzle different from a nozzle used in a preceding scan, among a plurality of nozzles provided on each of the plurality of ink heads, the final printing unit being continuous scans corresponding to the number of passes including a last scan, among the scans to be performed the scanning number of times, and the second ink being an ink whose density is equal to or less than the unit density.
