There are provided an information processing apparatus, a control method, and a storage medium, which are capable of suppressing the occurrence of an unintended print result. To this end, multiple spot colors that can be designated are displayed on a spot color setting screen. User selects the color to be used as the spot color while visually checking the multiple spot colors that the user can designate.

Provided is an image processing apparatus that enhances the distinctiveness of document having a color portion and outputs in monochrome. A monochrome visual determination unit determines whether or not the distinctiveness of the color portion is low when the document data having the color portion is output in monochrome. This color portion includes characters, electronic marks, and graphs, and they are after a specific keyword. A monochrome presentation unit presents to a user a warning or a result of modification when there is the color portion that the distinctiveness is determined to be low by the monochrome visual determination unit. The monochrome presentation unit presents a state in which the document data is output in monochrome by displaying a preview.

There are provided a control apparatus, a controlling method, and a storage medium, which are capable of suppressing the occurrence of an unintended print result. To this end, a controlling method includes a notifying step of executing a prescribed notification based on fulfillment of a prescribed condition concerning a region corresponding to first RGB values by print data even though a first setting is being activated, the first setting is to print a first print region corresponding to the first RGB values in a print target image by using a first color represented by use of at least a specific color ink being an ink of a color other than a process color.

Techniques for interactively determining/visualizing the color content of a source image and how the corresponding image data is mapped to device colors are described herein. For example, the color content of a digital image can be converted between different color spaces to identify gamut limitations of an output device (e.g., a printing assembly), discover color(s) that cannot be accurately reproduced, etc. Color space conversions enable the transformation of the color content of the digital image from device-specific colorants to a device-independent representation (and vice versa). In some embodiments, these transformations are facilitated using lookup tables that are implemented in graphical processing unit-resident memory.

An image processing apparatus includes an obtaining unit that obtains attribute information that specifies a process performed by an image forming apparatus in accordance with a print job including print data, an identification unit that identifies a color of a recording medium specified by the attribute information, a generation unit that generates a display image on a basis of the color of the recording medium identified by the identification unit and the print data included in the print job, and a determination unit that determines, as the color of the recording medium identified by the identification unit, a display color of a drawing area which corresponds to an area of the recording medium for printing the print data and in which the display image generated by the generation unit is to be disposed.

An image forming apparatus includes a memory and a processor configured to output an image formed based on image data including predetermined specific text after replacing a color of one or more portions in the image data with a special color that is in advance associated with the specific text, the one or more portions being assigned a color identical or similar to a color of the specific text to form the image.

An image processing device in which a display section is caused to display a preview image for printing. The image processing device includes a processing section configured to generate the preview image obtained by converting raster image data of each of ink colors of color inks or special color inks into an RGB bitmap format, and a display controller configured to cause the display section to display the generated preview.

A method of printing a three-dimensional (3D) color object, layer-by-layer, comprises: obtaining a 3D CAD specification defining a 3D geometry and a surface color distribution for the color object to be printed, defining regions on a surface of the color object; defining colors for each region based on the CAD specification; determining, using the 3D geometry of the specification, conditions applying at respective regions that are liable to cause color variation, such that using the colors as defined at the respective regions may give rise to a coloration error; selecting color corrections defined for respective determined conditions; correcting the defined colors; and printing the 3D color object with the color corrections.
