An image control device includes a reception unit that receives patch chart data items arranged such that the patch data items corresponding to a plurality of patches belonging to a same hue, among a plurality of patches constituting a patch chart, are positioned only in any of grid points of grid lines which divide a lightness axis and a saturation axis which define a hue plane corresponding to the hue at equal intervals, and a controller that outputs the patch chart data items to an image forming unit which forms the patch chart on a recording material if an output operation of the patch chart is received.

Image control device and non-transitory computer readable medium

An image forming device includes an image forming unit that forms an image on a recording medium in response to an input of image data representing the image, a reading unit that reads a first image formed by the image forming device, and a second image formed by another image forming device to respectively generate a first read image and a second read image, the first image and the second image being formed based on identical image data, a discrimination unit that discriminates the first read image and the second read image from each other, and a color correction unit that performs, on the image formed by the image forming unit, a color correction that cancels out a difference in color between the first read image and the second read image.

Image forming device, non-transitory computer readable medium, and image forming method for color correction

An image forming apparatus includes a classifying unit which classifies constituent elements constituting print data into a single or a plurality of areas based on a plurality of types of the constituent elements; a color conversion processing unit which performs, with respect to each of the constituent elements classified by the classifying unit, a color conversion coping with each type the constituent elements; and an image forming unit which composes the constituent elements subjected to the color conversion by the color conversion processing unit and forms an image based on the print data composed.

Image forming apparatus and computer readable medium for image forming

An image forming apparatus includes a tone correction storage unit that stores a plurality of tone correction charts for correcting tone of image data; a determination unit that determines characteristics of the image data; a selection unit that selects a tone correction chart suitable for the image data from the plurality of tone correction charts stored in the tone correction storage unit; a chart print unit that prints the tone correction chart selected by the selection unit on a sheet; a receiving unit that receives an adjustment value inputted based on the tone correction chart printed by the chart print unit; a tone correction unit that corrects tone of the image data based the adjustment value; and a print unit that prints out the image data after correcting tone of the image data.

Image forming apparatus and computer readable medium for forming image

An image forming apparatus includes a print data receiving unit that receives print data designating black as a color material for printing a code information portion; a discriminating unit that discriminates as to whether or not black as a color material is in a usable state; a print data generation unit that generates, when the discriminating unit discriminates that the color material of black is not the usable state, the print data that changes a designation of the color material of black as to the code information portion of the print data received by the print data receiving portion into a designation of other color material enabling the code information to be read by a code information reading apparatus; and an image forming unit that forms an image by the print data thus changed by the print data generation unit.

Image forming apparatus and computer readable medium for controlling image form

An image forming apparatus includes; a chart data forming unit that forms density correcting chart data to be printed, in which reference density patterns and adjusting density patterns are arranged so that a connection angle, and the adjusting density patterns have different densities in the respective patterns; a printing unit that prints a density correcting chart in which the reference density patterns and the adjusting density patterns are arranged adjacent to each other in respective patterns; a receiving unit that receives an input of a density adjusting value of a desired pattern, on the basis of comparison of density between the reference density patterns and the adjusting density patterns which has been obtained from visual observation of a user on the printed density correcting chart; and a tone correcting unit that conducts tone correction of the desired pattern.

Image forming apparatus

An image forming apparatus includes an alternative printing unit. The alternative printing unit performs alternative printing of a black image by mixing images of color materials of three colors of cyan, yellow, and magenta. The alternative printing unit includes a color material amount control unit that controls amounts of the respective color materials, which form the images of the color materials of the three colors, so as to be smaller than those at a time of normal printing.
