摘要:
An image processing device includes a screen processing unit and a correction processing unit. The screen processing unit executes screen processing for an image to be processed. The correction processing unit performs correction processing of correcting a distortion of an output image from an original image, based on the amount of the distortion, for (i) the image before the screen processing and (ii) the image after the screen processing. The correction amount relating to the correction processing for the image after the screen processing is a small value as compared with the correction amount relating to the correction processing for the image before the screen processing.

The image processing apparatus includes a combining module that respectively combine a plurality of first patterns and a plurality of second patterns each corresponding to the first patterns. Respective densities of the first patterns are different from each other. At least one of the second patterns include a plurality of regions where respective coverages are different in a main scanning direction.

An image processing device includes a processor. The processor executes a screen process by using different screens for respective color components which are newly used in response to N colors ranging from a primary color in an output color space to a Nth color, in the output color space, obtained by mixing the primary color with other primary colors in order, where N denotes natural number equal to or larger than 2.

An image forming apparatus includes: an image data forming unit that forms an image data which includes a first dot image to be visible by copying, a second dot image to be invisible by copying, a hidden text portion and the background portion; and an image forming unit that carries out image formation by using the image data formed by the image data forming unit. the first dot image has a first color, the first dot image includes dots having a dot size increased by decreasing the number of lines of dots, the second dot image has a second color, the second dot images includes dots having a dot size decreased by increasing the number of lines of dots, and the second dot image is stacked on the first dot image in at least one of a hidden text portion or a background portion.

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.

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.
摘要:
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
