There is provided a head system includes: a main controller; a plurality of head units; and sub-controllers respectively connected to at least one of the plurality of head units. The sub-controllers are each serially connected via a wiring. The wiring includes: a first communication path for transmitting an image signal; and a second communication path that transmits a discharge timepoint signal indicating a discharge timepoint. Each of the sub-controllers is configured to cause liquid corresponding to an image indicated by the image signal that has been received through the first communication path to be discharged from nozzles of one of the head units to which each of the sub-controllers have been connected, at a discharge timepoint indicated by the discharge timepoint signal that has been received through the second communication path.

Methods for printing using printing systems comprising a flexible intermediate transfer member (ITM) disposed around a plurality of guide rollers at which encoders are installed, and an image-forming station at which ink images are formed by droplet deposition by print bars onto the ITM, can include measuring a local velocity of the ITM under one of the print bars, determining a stretch factor for a portion of the ITM based on a relationship between an estimated stretched length fixed physical distance between print bars, controlling an ink deposition parameter according to the stretch factor so as to compensate for stretching of the reference portion of the ITM.

An integrated circuit to drive a plurality of fluid actuation devices includes a plurality of first non-volatile memory cells and control logic. Each first non-volatile memory cell stores a customization bit. The control logic configures an operation of the integrated circuit based on the customization bits.

Disclosed is an industrial single-pass inkjet printer/press incorporating a line-scan camera. The line-scan camera enables system software to inspect every sheet for quality assurance purposes. These inspection results are tied back to a digital printer to take one or more of several possible actions. Actions include ensuring a particular number of acceptable prints are generated and sorted. Actions further include performing nozzle checks without pausing or interrupting production orders.

Print data is organized over rows and columns. The columns of each row are selectively assigned to calibration tables respectively corresponding to printheads of a pagewide array in accordance with a substrate advancement skew relative to the pagewide array. The calibration tables are applied to the columns of each row respectively assigned to the calibration tables. The columns of each row to which the calibration tables have been applied are printed using the printheads respectively corresponding to the calibration tables.

An inkjet printer configured to control the temperature of ink discharged from nozzles of an inkjet head is proposed. The inkjet printer includes: an inkjet head including a plurality of nozzles configured to discharge ink, an ink reservoir configured to store ink supplied to the inkjet head, a supply channel configured to supply the ink in the ink reservoir to the inkjet head, a pressure control device connected to the ink reservoir through a pressure control tube and configured to maintain the meniscus of the ink injected into the inkjet head, and the ink temperature control unit configured to control temperature of the ink discharged from the inkjet head.

Disclosed is a printing device including at least one processor and a print head. The processor detects a nail region based on an image obtained by photographing a finger or a toe, sets at least a part of the detected nail region as a preceding print setting region, detects a region on which the preceding print is printed as a succeeding print region based on an image obtained by photographing the finger or the toe on which the preceding print is printed, sets a succeeding print region reference point corresponding to the succeeding print region, or sets a preceding print setting region reference point corresponding to the preceding print setting region and the succeeding print region reference point, and causes the print head to print a succeeding print on the nail region based on information on the preceding print setting region and a reference point that is set.

An information processing device for generating data to be used by a recording device, which includes a plurality of discharge portions configured to discharge a liquid to form the object on the medium, includes a communication circuit configured to communicate with the recording device; an identifying unit configured to identify, based on a movement direction of the recording device in formation of the object on the medium, an initial pixel of the object formed by an initial discharge of the liquid by each of the plurality of discharge portions; a data generation unit configured to generate discharge control data for controlling a discharge operation of each of the plurality of discharge portions for the initial pixel identified by the identifying unit; and a transmission control unit configured to control the communication circuit to transmit the discharge control data to the recording device.

According to an example, a calibration method may calculate a printhead distribution. The method may comprise printing a calibration pattern, detecting darkness values from the calibration pattern, assigning a darkness level to a plurality of printheads based on the darkness values, and calculating through a processor the printhead distribution that minimizes a variation of the darkness levels across the plurality of printheads.

The disclosure more appropriately creates a product of printing closer to the target state. A printing system (10) that creates a product of printing includes a printer (16) that is a printing apparatus that executes a printing step, a steaming machine (18) that is a device for a predetermined step that is a device that executes a predetermined step, and a control device (12); where the control device (12) acquires printed matter information that is information indicating a state of a printed matter obtained by performing the printing step by the printer (16), and adjusts a condition of a step to be executed in the steaming machine (18) based on information indicating a state of the target product and the printed matter information such that a product in a state closer to a state indicated by target product information is obtained.
