In a method and device for ascertaining print data for a print image to be printed, the print data is adapted and/or determined such that the time curve of the ink flow quantity, exhibits no quantity changes or flow rates due to which ink ejection errors might be produced, in particular nozzle failures. The time curve may have been produced by the print data,

In an example, a method includes selecting a unique identifier corresponding to a set of rules. At least one modified image is generated from a seed image using a processor by determining and applying an image attribute modification to the seed image according to at least one rule in the set of rules of the unique identifier. The modified image is placed in a predefined position according to at least one rule in the set of rules of the unique identifier.

A printing device may include a processor to receive data describing a plurality of independent print streams comprising an image; for each of the plurality of independent print streams, emulate a first frame-less press using gapless frames on a first side of a medium upon execution of a framing module wherein each of the images of the independent print streams comprise an emulated spitgap; for each of the plurality of independent print streams, emulating a second frame-less press using gapless frames on a second side of the medium with the framing module, wherein an emulated spitgap associated with each of the images of the second side of the medium is to be geometrically adjusted to match a position on the medium of an image on the first side of the medium.

An object is to reduce a difference between a target line width and a width of a line that is printed by a printing apparatus by correcting the line width in accordance with color information indicating a color of the line in a case where an image is printed by the printing apparatus based on image data including the line based on print data. The present disclosure is an image processing apparatus having an acquisition unit configured to acquire a drawing command in which a color and a line width of a line are specified, a determination unit configured to determine a correction amount for correcting the line width specified in the drawing command based on the color of the line specified in the drawing command, and a correction unit configured to correct the line width specified in the drawing command in accordance with the correction amount.

A method for checking a surface of an object, imprinted and/or structured in raster form, includes: a) using a digital image, which reproduces a replica of the surface, b) checking and/or determining a property of the surface or the replica using the digital image and/or the replica, and c) outputting a result with reference to the property. Step b) includes constructing and/or reconstructing a raster made from raster elements, using the digital image and/or the replica in which at least one raster element parameter can assume two or more, differently large size, brightness, and/or color parameter values, depending on the position of the corresponding raster element. The surface property is checked and/or determined as a function of the differently large parameter values and/or of the distribution of these differently large parameter values on the raster elements, and the result is output in Step c).

A positional-deviation correcting device includes a reading device and control circuitry. The reading device reads recording media on which marks and each of adjustment charts having different image densities are formed in accordance with the image densities. The control circuitry acquires data on image formation positions of the marks on the recording media, based on a reading result of the marks; and corrects an image formation position of an image to be formed on a recording medium. The control circuitry calculates a correction value of the image formation position corresponding to an image density for each of the image densities corresponding to the adjustment charts on a one-on-one relationship, based on a reading result of the adjustment charts; interpolates correction values corresponding to the image densities on a one-on-one relationship; and calculates a correction value of the image formation position corresponding to another image density different from the image densities.

Disclosed are a print for touch-read, and a production method and production system for touch-read content of a print. The production method for touch-read content of a print comprises the following steps: S1: coding: when receiving a coordinate coding signal, dividing a print according to virtual grid lines of M rows by N columns, wherein the virtual grid lines divide the print into multiple virtual spaces, each virtual space being provided with a code value, and the code values are continuously set according to row coordinates and column coordinates of the virtual grid lines in an increasing or decreasing manner; and S2: planning touch-read content: before or after the coding is completed, choosing a touch-read area on the print, and planning touch-read content associated with the touch-read area.

Systems and methods are described for inline rendering of a color filter within a print job. A program associated with a printing system can select an overhead transparency media to serve as a color filter during inline print job finishing. A duplex path and finishing for the transparency media can be enabled on the printing system by the program. A first side of the overhead transparency media can be printed on with one or more colors by the printing system by the program. A transform can be used on a second side of the overhead transparency media to correct for front to back registration and includes one or more colors printed directly underneath colors printed on the first side by the program. The transparency medium including color filters can be inserted into pages of the print job, which can be rendered in the form of a bound book.

A raster image processing system including a computer readable media storing digital information that includes information corresponding to an image, and instructions for performing raster image processing (RIP) using an over scan RIP technique on the image to generate a bitmap. Also included is a processor configured to RIP the image using the over scan RIP technique at a multiple of the desired output pixel resolution to produce a plurality of sub-pixels per output pixel. The processor is further configured to determine each image output pixel value based on the values set for the plurality of sub-pixels of each image pixel, by firstly comparing the values of the plurality of sub-pixels to each other and, and then secondly comparing the values of the plurality of sub-pixels to a set background value if needed. The processor then sets the output pixel value based upon that second comparison, and generates a bitmap.
