A liquid discharge apparatus includes liquid discharge head units, an image sensor, and processing circuitry. The circuitry detects, based on image data detected by the sensor, an amount of deviation between positions on an object onto which liquid has been discharged by the head units; corrects a timing of discharging the liquid, based on the amount of deviation; switches between first control of conveying the object at a first speed while the sensor images the object with a first image size and second control of conveying the object at a second speed faster than the first speed while the sensor images the object with a second image size having a smaller number of pixels; and sets pixel positions of the sensor used for imaging during the second control, according to the amount of deviation detected based on the image data imaged with the first image size by the first control.

A printing apparatus, having a conveyer, a first conveyer path, a printer, a cutter assembly, and a controller, is provided. The controller controls the printer to print images for at least two pages on a first side of a printing medium; after printing the images on the first side of the printing medium, controls the conveyer to move the printing medium to a second conveyer path being a different path from the first conveyer path through a switchback action and invert the printing medium by conveying in a second conveying direction; after inverting the printing medium, controls the printer to print an image in a predetermined part on a second side opposite to the first side of the printing medium; and after printing the image in the predetermined part on the second side of the printing medium, control the cutter assembly to cut the printing medium.

An image recording device comprises a conveyance mechanism, a head, a sensor configured to detect a position of an orthogonal edge of recording medium in a direction orthogonal to a conveyance direction, and a controller. The controller tentatively determines, for each of a plurality of unit areas aligned in the conveyance direction on the recording medium, a recording position of an image for the unit area based on image data and a size of the recording medium, derives a correction amount for the tentatively determined recording position, determines whether the correction amount exceeds a first upper limit for each unit area. When it is determined that the correction amount does not exceed the first upper limit, The controller determines the recording position based on the correction amount, and causes the head to record an image at the recording position determined in the determining.

Disclosed are various embodiments of systems and methods that facilitate printer calibration. According to certain embodiments, calibration methods comprise a printer printing a calibration target and cutting a calibration target using an inline slitter. The printer then determines a calibration offset based on the position of the cut on the calibration target. The printer can then be calibrated according to gross amounts on the slitter and fine amounts at an ink applicator.

In a printing method, at least one image of a substrate supported in a printing system is acquired. An actual position of a first alignment feature on the substrate in a frame of reference of the printing system is determined based on the at least one image. Expected positions of second alignment features on the substrate are determined based on the actual position of the first alignment feature. Actual positions of the second alignment features in the frame of reference of the printing system are determined based on the at least one image and the expected positions of the second alignment features. Target positions of print regions on the substrate are determined based on the actual positions of the second alignment features. Ejection of print material onto the substrate in the print regions is controlled based on the target positions of the print regions.

According to one example of the present invention there is provided a method of printing, with a printer, an image on a substrate, the printer comprising a substrate support. The method comprises obtaining an image to be printed, determining an offset position of a substrate positioned on the substrate support relative to a predetermined reference printing position, and controlling the printer to print the image to be printed at the determined offset position.

A printing apparatus includes a holder which holds printing media, a conveying unit which conveys each of the printing media picked up from the holder, along a conveyance direction, a printing unit which prints an image on the printing media, a first detecting unit which detects a front end and a rear end in the conveyance direction of each of the printing media conveyed by the conveying unit, a processing unit which processes each of the printing media, by moving a processing member with the processing member contacting each of the printing media, and a controller configured to: calculate lengths of the printing media by using detected results by the first detecting unit; and based on the lengths of the printing media, set a processing position in the conveyance direction at which the processing unit processes each of the printing media.

The present disclosure relates to a device for simultaneously performing printing of tablets and inspection on exteriors of the tablets, and provides a device for printing a tablet and inspecting an exterior of the tablet, comprising a transfer unit arranging and transferring tablets supplied from a tablet supplier in a line; a pre-printing image-capturing unit located on a transfer path on which the tablets are transferred to discriminate positions and orientations of the tablets, and disposed to capture images of exteriors of the tablets being transferred; a tablet printing unit located next to the pre-printing image-capturing unit on the transfer path on which the tablets are transferred, and printing the tablets being transferred, in consideration of discriminated results acquired from the images captured by the pre-printing image-capturing unit; and a post-printing image-capturing unit located next to the tablet printing unit on the transfer path on which the tablets are transferred, and capturing images of exteriors of the printed tablets being transferred, to inspect the images or printed results of the printed tablets. According to an embodiment of the present disclosure, a plurality of functions may be performed with a single device, to maximize work efficiency in time and space, and reduce costs.
