A learning device includes an acquiring unit and a learning unit. The acquiring unit acquires an image and correction information designated for printing the image. The learning unit performs machine learning on recommended correction information that indicates correction content recommended for the print target image in printing the print target image, based on the data set in which the image is associated with the correction information.

A method of optimizing printing is applied to a printing apparatus and has following steps of retrieving an input image, executing a tagging process on the input image for tagging one of an edge tag, a fuzzy tag, and a photo tag on each sub-image of the input image, executing the different printing converting process on each sub-image according to its tag for obtaining a printable image, and printing according to the printable image. The present disclosed example can deepen the object edges in the image being printed, improving the image quality of non-edge regions, and improving the printing quality.

The present disclosure is directed to a technique for outputting images so that a user can easily compare the image on which image processing is executed and the image on which image processing is not executed. In the technique, a first image of a region of an output target in a predetermined image on which predetermined image processing is not executed and a second image of the region of the output target in the predetermined image on which the predetermined image processing is executed are output by an output apparatus so that the first image and the second image are output and arranged in an output layout according to a shape of the region of the output target.

An image processing apparatus corrects a measured value obtained by measuring a measurement image formed using a printing element configured to discharge ink, the measured value being used to identify a density characteristic of the printing element. The image processing apparatus obtains a measured value; and corrects the measured value based on a density of the measurement image.

An image forming apparatus includes an image forming portion, an image reading portion, an analysis processing portion, a generation processing portion, and a printing processing portion. The image forming portion forms an image on a paper sheet. The image reading portion reads a first image from a printed side of a used paper sheet supplied from a sheet feed portion. The analysis processing portion analyzes content of the first image read by the image reading portion. The generation processing portion generates, based on the content of the first image analyzed by the analysis processing portion, a second image that degrades visibility of the first image when the second image is superimposed on the first image. The printing processing portion causes the image forming portion to execute a printing process such that the second image generated by the generation processing portion is superimposed on the first image on the printed side.

A die controller to control a fluidic die having a plurality of primitives each including a plurality of nozzles addressed by a same set of addresses. The die controller provides operational data including a series of actuation data groups to the fluidic die to actuate the nozzles to eject fluid to form an article, each actuation data group including a series of fire pulse groups, with each fire pulse group corresponding to a different address of the set of addresses and including a set of actuation data for each primitive and a set of start bits to initiate actuation of the nozzles based on the actuation data of the immediately preceding fire pulse group. The die controller to provide a blank fire pulse group immediately following a last fire pulse group of the series of fire pulse groups of each actuation data group when operating in an edge sharpness mode.

A recording device includes a recording unit configured to execute recording on a recording medium using a color material of cyan, magenta, yellow, and black, and a control unit configured to control recording executed by the recording unit, wherein the control unit causes the recording unit to record an edge region of black data included in image data using at least the color material of black, causes the recording unit to record an inner region on an inner side of the edge region of the black data using at least the color material of cyan, magenta, and yellow, and sets the amount of the color material of black per unit area of the edge region to be greater than the amount of the color material of black per unit area of the inner region.

A method of optimizing printing is applied to a printing apparatus and has following steps of retrieving an input image, executing a tagging process on the input image for tagging one of an edge tag, a fuzzy tag, and a photo tag on each sub-image of the input image, executing the different printing converting process on each sub-image according to its tag for obtaining a printable image, and printing according to the printable image. The present disclosed example can deepen the object edges in the image being printed, improving the image quality of non-edge regions, and improving the printing quality.

A width in a first direction of a line in image data corresponding to an image to be printed by a printing apparatus is corrected, based on information on a print result of line-width detection images printed based on line-width detection image data in a raster format that is generated by performing rasterization processing on line-width detection image data in a vector format. In the line-width detection image data in the vector format, a distance between centers of the widths in the first direction of two lines adjacent in the first direction in each line-width detection image is an integral multiple of a rasterization resolution in the rasterization processing.

A printed object management apparatus (10) is provided with: a line sensor (11); a spectrophotometer (12); an area camera (13); a print quality-inspecting unit (10A) for inspecting the quality of the overall pattern of a printed object (9) on the basis of data input from the line sensor (11); a print density controlling unit (10B) for controlling, on the basis of data input from the spectrophotometer (12), the amount of ink supplied so that the ink density equals the reference density; and an inter-color registering unit (10C) for detecting register marks printed on the printed object (9) on the basis of data input from the area camera (13) and aligning the patterns between the various colors. The apparatus is configured so as to support the line sensor (11), the spectrophotometer (12) and the area camera (13) on a single scanning head (10b).
