Provided are an inkjet printing apparatus and a method for inspecting an inkjet head using same. The inkjet printing apparatus comprises: an inspection stage unit on which an inspection substrate is seated; an inkjet head unit including at least one inkjet head that ejects ink containing dipoles and a solvent in which the dipoles disperse, on the inspection stage unit; and a particle count inspection unit that is located so as to be spaced apart from the inkjet head unit in one direction. The particle count inspection unit comprises: a first heat treatment unit that is located on the top portion of the inspection stage unit; and a first sensing unit that is located on the bottom portion of the inspection stage unit and measures the number of dipoles sprayed onto the inspection substrate.

A printing device including: an ejector that ejects a first droplet to a print medium partially having a curved surface while moving in a first direction, and ejects a second droplet corresponding to the first droplet to the print medium while moving in a second direction opposite to the first direction; and a processor that obtains correction level information based on a distance between the print medium and the ejector and reference data that associates a correction level with each area obtained by dividing the print medium into multiple areas in a width direction and that performs ejection control of at least one of ejection of the first droplet and ejection of the second droplet based on the obtained correction level information so that a landing position on the print medium of the first droplet and a landing position of the second droplet substantially match each other.

A deposition module within a web press for inhibiting media deformation may include a fluid deposition device located on a side of a media, and a processing device to control the fluid deposition device to selectively apply a wetting agent to the media. The deposition of the wetting agent may be based on the location of content printed on the media as defined by print data.

An information processing apparatus includes a processor configured to: acquire physical property information on physical properties of a recording medium and on physical properties of an ink to be ejected onto the recording medium and setting information on a setting of a device configured to eject the ink onto the recording medium, the ink including a first ink and a second ink, derive an action amount using the physical property information and the setting information, the action amount relating to an action of the second ink ejected at a position different from a position where the first ink is ejected, the second ink ejected being acted upon by behavior of the first ink, and output the action amount.

A printing system is disclosed. The printing system includes at least one physical memory device to store uniformity compensation logic and one or more processors coupled with the at least one physical memory device to execute the uniformity compensation logic to receive print image measurement data corresponding with each of a plurality of pel forming elements, generate a first set of intermediate images based on the print image measurement data, determine whether historical sets of intermediate images are available, generate first transfer functions corresponding to each of the pel forming elements based on the first set of intermediate images and the historical sets of intermediate images upon a determination that the historical sets of intermediate images are available and transmit the first transfer functions for each of the pel forming elements.

An integrated circuit to drive a plurality of actuators during a non-reset operating condition is disclosed. The integrated circuit includes a reset input to receive a reset signal activated for a duration. The reset signal generates a reset condition in the integrated circuit during which the non-reset operating condition is blocked.
