A printing apparatus performing printing by an inkjet scheme includes: an inkjet head; and a controller, configured to control the operation of a main scan driver and a sub scan driver to perform a main scanning operation multiple times on each position on a medium. In the main scanning operation, for at least part of ejection positions serving as ejection targets of ink droplets in the main scanning operation, the controller causes the inkjet head to eject an ink droplet in accordance with a mask for selecting part of the at least part of ejection positions.

Systems and methods for providing remote approval of an image for printing are provided. One system includes a processing circuit in communication with an image capturing device that is configured to capture an image of a printed product. The processing circuit is configured to process the captured image into a processed image accurate to within a tolerance in a color space to indicate the visual appearance of one or more colors. The color space is a standardized color space, such as sRGB or CIELAB. The processing circuit is further configured to transmit the processed image to a display located remote from the image capturing device and to receive an input signal from a remote input device to allow a user to approve or reject the displayed processed image for printing on a print device.

Examples relate to providing synchronized look-up table loading. In some examples, a print job is processed using an initial look-up table in processor memory. In response to the processing of the print job reaching a buffer trigger row of a portion of the print job, look-up metadata is accessed to locate a next look-up table. At this stage, the next look-up table is dynamically loaded into the processor memory as the processor continues to process the print job, where the processing of the print job begins using the next look-up table after a target row of the portion of the print job is reached.

This disclosure is directed to improving the precision of color reproducibility in a whole image region of any product provided with a base layer(s) regardless of any form of the base layer(s). The RIP (Raster Image Processor) device includes a color conversion processor that applies a color conversion process adapted for presence or absence of a base layer and for a base color to content data representing part or all of details of an image layer at a respective one of positions in an image region indicated by the image layer, and an image layer data generator that generates image layer data representing ejection-related information of ink droplets of a plurality of colors using the content data that has been subjected to the color conversion process.

A specification part of an information processing device specifies, by using image data for a correction chart defining a plurality of patch regions having different color values, a target characteristic indicating a relation between the color value and a first colorimetric value of a first patch image as a laminated image of a special color image and a colored image that correspond to each of the patch regions formed by the device through the 2-path printing. A generation part of the device generates a correction table for correcting the color value so that a measured characteristic comes close to the target characteristic, the measured characteristic indicating a relation between the color value and a second colorimetric value of a second patch image as the laminated image corresponding to each of the patch regions formed by the device through the 1-path printing using the image data for a correction chart.

A data structure includes entries corresponding to a plurality of tiles that form part of an image, where a given entry of the entries includes color information for a given tile of the plurality of tiles. Image data in the given tile is created using the color information of the given entry, where creating the image data in the given tile using the color information of the given entry is performed without using input image data for the given tile.

In an example, a method includes characterising, using at least one computer, an initial gamut from an initial set of color mappings from a source color space to a printing device color space. The method may further include characterising, using at least one computer, an initial gamut from an initial set of color mappings from a source color space to a printing device color space. The method may further include characterising, using the at least one computer, a printing device color gamut. The method may further include transforming, using the at least one computer, the initial set of color mappings to form a transformed set of color mappings mapping from the source color space to the printing device color gamut.

An image processing apparatus includes a management unit and a plurality of image processing modules. Each of the image processing modules performs image processing. The management unit manages a processing status of each of the image processing modules. The number of colors and the number of pixels for each of the colors are set as a processing unit for each of the image processing modules, and each of the image processing modules starts the image processing using the processing unit which is set, on the basis of the processing status of a previous image processing module among the processing statuses managed by the management unit.

A printer is disclosed. The printer uses a target located on one side of media to position an image on the other side of the media. The printer backlights the media and uses a sensor that locates the target through the backlit media.
