A printing apparatus determines whether or not predetermined processing in accordance with a predetermined shape of a medium is executed on an image of a printing target. In a case where it is determined that the predetermined processing is not executed on the image of the printing target, the printing apparatus executes the predetermined processing on the image of the printing target to perform printing. In a case where it is determined that the predetermined processing is executed on the image of the printing target, the printing apparatus prints the image of the printing target on which the predetermined processing is not executed.

Example implementations relate to multiple payload pantograph. Some examples may include a first pattern generation engine to generate a first pattern. The first pattern may be a data-bearing pattern encoding a first payload. Additionally, some examples may include a second pattern generation engine to generate a second pattern, the second pattern (by itself or in combination with the first pattern) may represent a second payload. The second payload may be camouflaged by a combination of the first pattern and the second pattern. Some examples may also include a pantograph generation engine to generate a multiple payload pantograph including the first pattern and the second pattern. The multiple payload pantograph may include the first pattern in one of the pantograph background or the pantograph foreground.

A non-transitory recording medium storing a computer readable program causes a computer to execute: a) analyzing unconverted first page description language data to determine whether a repetitive pattern image portion is included in the first page description language data; b) separating the repetitive pattern image portion from the first page description language data when it is determined that the repetitive pattern image portion is included in the first page description language data; c) generating first partial data in a second page description language; d) generating second partial data in the second page description language based on a portion other than the repetitive pattern image portion of the first page description language data; and e) generating converted data that relates to the first page description language data and is second page description language data based on the first partial data and the second partial data.

A white-plate graphic erosion process is performed on print data subjected to a RIP process in the following procedure. First, an erosion candidate region which is a candidate for a region in which a white-plate graphic is eroded is determined. Then, a region to be applied with an ink of a color other than white is determined. Then, an application target region is determined. Then, a region other than a region obtained by an erosion process out of the application target region is determined to be an erosion allowed region. Then, a region included in the colored region and the erosion allowed region out of the erosion candidate region is determined to be an erosion target region. Finally, the values of data of pixels included in the erosion target region among white-plate data are rewritten such that the amount of white ink applied to the pixels is reduced.

In an example, a method includes receiving print data indicative of an image to be printed on a substrate. The print data may indicate an image portion in which an image is present and a void portion in which the image is absent. An amount of background print agent to be applied to a region of the substrate corresponding to the locations of the image portion and the void portion on the substrate when the image is printed may be determined. In examples, the amount of background print agent determined to be applied to a region of the substrate corresponding to the location of the void portion on the substrate when the image is printed is greater than the amount of a background print agent to be applied to the region of the substrate corresponding to the location of the image portion on the substrate when the image is printed.

A system, device, and method for printing N-up documents with background forms, by receiving an instruction to print an N-up document, obtaining a document to be printed as the N-up document and a background form, receiving matchings of logical surfaces of the N-up document to the background form, decomposing the logical surfaces of the N-up document into raster images, generating tags, wherein each tag is associated with a pixel of a logical surface of the N-up document and identifies the logical surface, combining raster images of the logical surfaces into an N-up raster image, merging, using the tags, the background form with the N-up raster image to generate a merged N-up raster image, and printing the merged N-up raster image.

An image processing apparatus including a contour extraction section which extracts a contour pixel of an object from pixels in image data that has tone values of a plurality of colors for each of the pixels; and a contour processing section which executes thinning processing of adjusting a tone value of an object color of the object and trapping processing of adjusting a tone value of a background color among tone values of colors in the contour pixel of the object which is extracted by the contour extraction section or in a contour pixel of the background of the object, wherein the contour processing section links an adjustment amount of the tone value of the background color by the trapping processing to an adjustment amount of the tone value of the object color by the thinning processing.

Disclosed herein are methods and systems for generating one or more cut contours based on object types. The method includes receiving from a user a print job including a first file having objects and receiving at least one object type and a cut width for printing the job at a printer. Based on the at least one object type, corresponding objects are extracted from the first file. Then, automatically cut contours are generated while creating a raster image for the extracted objects. The cut contour is generated at the cut width distance outside a boundary of each object. The cut contour then is embedded around each object in the raster image to generate a second file. The cut contour is embedded using a specific color. The second file including the cut contour in the specific color around each object is printed.

Methods and devices process an electronic image of an item that has a background color and line features of a second color distinct from the background color. An electronic image and a menu option are displayed to allow the user to define at least one area of the electronic image as a distinctive color region. The electronic image is separated into different planes, and line features within the distinctive color region are removed from a second mask plane (second color) and added to a third mask plane (third color). The first plane, second mask plane, and third mask plane, are combined into an electronic file, and automatically stored.
