Certain embodiments provide an image forming apparatus, including: an image forming part to form an image made of plural pixels by using plural printing colors and a special color different from the plural printing colors; an input part of image data of the image; an image processing part to output component data of the plural printing colors from the image data for each of the pixels; a user interface to specify a condition for converting the component data of the plural printing colors into component data of a multi color in which the special color is added to the plural printing colors; and a conversion part to convert the component data of the plural printing colors from the image processing part into the component data of the multi color to the image forming part based on the condition of the user interface.

A print apparatus is provided that executes a print using print data that is stored in the apparatus, and in addition to executing post-processing on output materials after the printing, deletes the corresponding print data when processing of the print job ends. Here, the print apparatus according to the embodiment deletes the corresponding print data only in a case when the post-processing to all the sheets or the like set in one print job successfully ends.

Certain embodiments provide an image forming apparatus, including: an image forming part to form an image made of plural pixels by using plural printing colors and a special color different from the plural printing colors; an input part of image data of the image; an image processing part to output component data of the plural printing colors from the image data for each of the pixels; a user interface to specify a condition for converting the component data of the plural printing colors into component data of a multi color in which the special color is added to the plural printing colors; and a conversion part to convert the component data of the plural printing colors from the image processing part into the component data of the multi color to the image forming part based on the condition of the user interface.

A printing apparatus that prints images on a roll paper based on a job prints one or a plurality of image sets, each formed of a partition page image and a content image, on the roll paper based on a job in which partition information for inserting a partition page is set. In a case where the printing apparatus executes printing based on the job in which the partition information is set, control is performed to determine, based on a remaining amount of the roll paper loaded on the printing apparatus, a number of image sets that can be printed on the roll paper without interruption from among the image sets based on the job to print the determined number of image sets on the roll paper loaded on the printing apparatus.

A print controlling apparatus includes: a receiving unit that receives input data including: gloss control plane data indicating a surface effect type to be achieved on the recording medium with certain density information; and table identifying information for identifying a surface effect selection table indicating a corresponding relation between the surface effect type and the density information used to generate the gloss control plane data; an acquiring unit that acquires an independent data portion indicating a portion corresponding to the surface effect type capable of being achieved independent from competence of the printing apparatus, out of the surface effect selection table identified by the table identifying information included in the input data from an external device; and a generating unit that generates the clear toner plane data using the independent data portion acquired by the acquiring unit.

An image forming apparatus includes: an image forming device and a control device. The control device functions as: a white region extractor that extracts a white region from an output target image; a high-brightness region extractor that extracts a high-brightness region adjacent to the white region; a color change determiner that determines whether a change in image of the high-brightness region toward the white region is a first change from lower to higher brightness or a second change from higher to lower brightness; a region generator that, in the case of the first change, copies a portion of a higher-brightness subregion of the high-brightness region to generates an adjustment white region; an image regenerator that replaces the white region with the adjustment white region to regenerate the output target image; and a controller that allows the image forming device to form the regenerated output target image on a recording sheet.

A non-transitory computer-readable storage medium stores a program including: a special plate generation function for generating special plate data based on image data; a special plate printing function for printing the special plate data using special color ink; and an image printing function for printing the image data at a position overlapping the special color ink. A relative position between a position at which the special color ink of the special plate data is printed and a position of an object of the image data corresponds to a type of the object.

In an image forming apparatus, an adjustment processing portion allows, in a case where a printing type of a print process to be executed by a print processing portion is changed from either monochrome or color printing, a condition adjustment process of adjusting an image formation condition of an image forming portion to be executed before execution of the monochrome or color printing subsequent to a change of the printing type. The print processing portion allows line speed of the image forming portion to be changed depending on a combination of a line speed mode and the printing type set in association with a sheet type of a sheet. In addition, the adjustment processing portion allows execution of the condition adjustment process to be restricted if the line speed mode is identical before and after a change of the printing type and a restriction condition is set in advance.

The image processing method includes (a) receiving the stacking order of the print medium and one or more print layers, (b) displaying a preview image representing a state in which one or more virtual three dimensional objects corresponding to one or more print layers and the three dimensional object printed on the print medium are superimposed and combined, the preview image corresponding to how the preview image appears in a three dimensional virtual space, (c) displaying the preview image representing a state in which one or more three dimensional objects corresponding to one or more print layers and the three dimensional object printed on the print medium are stacked in the stacking order with intervals between them, the preview image corresponding to how the preview image appears in the virtual space, (d) receiving an instruction to execute one of (b) and (c), and executing the instructed one of (b) and (c).

There is provided an image-forming apparatus including: an image-forming unit configured to form a toner image on a sheet based on image data; a setting unit configured to set a first mode to form the toner image for gluing a foil onto the sheet via the toner image; and a control unit configured to control a display unit to display an alert depending on a shape of the toner image to be formed by the image-forming unit in a case where the first mode is set by the setting unit.
