Abstract: There are provided an ink jet printing apparatus and a color conversion processing device that can prevent the generation of offset and blocking and can stably jet ink. A first LUT in which a total amount of ink after conversion is large overall and a second LUT in which a total amount of ink after conversion is small overall are prepared as a look-up table (LUT) that is used in color conversion processing. A LUT to be used is selected according to the number of printed mediums. The first LUT is selected in a case in which the number of printed mediums is smaller than a threshold value, and the second LUT is selected in a case in which the number of printed mediums is equal to or larger than a threshold value.

Abstract: Test patterns are printed by ink jet means for jetting ink containing a color material and transparent liquid jet means for jetting transparent liquid. In the test patterns, ink and transparent liquid are applied to different regions on the same medium and ink application regions and transparent liquid application regions are arranged adjacent to each other. A device for determining the amount of transparent liquid to be jetted includes information acquisition means for acquiring information representing the amount of medium deformation of a medium on which the test patterns are printed, and information processing means for determining the amount of transparent liquid to be jetted by the transparent liquid jet means for jetting the transparent liquid, from the information representing the amount of medium deformation acquired by the information acquisition means.

Abstract: To provide a head device, a liquid jetting apparatus, and a head maintenance method with which it is possible to suppress a decrease in performance of a liquid-repellent film on a nozzle surface that is caused by a wiping process with respect to the nozzle surface. Provided is a head device including an ink jet head (10) in which a liquid-repellent film (10B) is formed on a nozzle surface (10A) and a head control unit. The head control unit applies a negative pressure to liquid in a nozzle, performs a non-jetting driving operation of causing the liquid in the nozzle to vibrate without being jetted, and stops the non-jetting driving operation for a wiping target nozzle (12A) with which a wiping member (22) to be used in a wiping process comes into contact in a case where the wiping process with respect to the nozzle surface is to be performed.

Abstract: A plurality of recording elements included in a printed head are grouped into a plurality of groups, a test order is set in units of groups, and a test of the recording elements is periodically performed in units of groups in the set test order. In a case where an abnormality is detected in the recording element as a result of the test, the recording element in which an abnormality is detected is recognized as a retest target, an order of tests is changed through interruption, and a retest of a group including the recording element recognized as a retest target is performed. In a case where an abnormality is detected again in the recording element that is a retest target as a result of the retest, the recording element that is a retest target is recognized as an abnormal recording element.
