Abstract: An image forming apparatus that forms an image where occurrence of concentration unevenness caused by occurrence of mechanical crosstalk is suppressed are provided. According to the present invention, the distance from the boundary position of the inkjet head corresponding to the concentration boundary between the first concentration region and the second concentration region to the second concentration region end of the inkjet head is less than the reciprocal of the spatial frequency of the concentration unevenness. Accordingly, the length of the part in the first direction where the inkjet head forms the second concentration region is less than one period of the concentration unevenness. Even if crosstalk due to vibrations of the part where the inkjet head forms the first concentration region occurs, the visibility of the concentration unevenness occurring in the second concentration region can be reduced.

Abstract: A method for adjusting a head module of an inkjet head in which a plurality of head modules having nozzles capable of ejecting droplets are connected and linked together is disclosed. The inkjet head has an overlapping region in which an arrangement sequence of the head modules corresponding to the ejected droplets is alternate between adjacent head modules. The method includes the steps of: obtaining, among intervals between the droplet ejected by one of the head modules and the droplet ejected by another one of the head modules in the overlapping region, a largest interval between the droplets in a direction of alignment of the head modules based upon movement of the droplets caused by a landing interference; and adjusting the adjacent head modules in a direction to decrease the largest interval between the droplets.

Abstract: A printing device includes a jetting section that jets out ink, a storage section that stores the ink, a supply channel through which the ink flows from the storage section toward the jetting section, a recovery channel through which the ink flows from the jetting section toward the storage section, a filter provided on at least one of the supply channel and the recovery channel, a pump provided on at least one of the supply channel and the recovery channel, and a control section. The control section applies control to the pump to make a flow speed of the ink in a non-printing period smaller than a flow speed of the ink in a printing period, the printing period including a period from a printing start time to a printing completion time, and the non-printing period being outside the printing period.
