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 a normal print order setter, a multiple print order and base material setter, and a preview image generator. The normal print order setter is configured to set types of color materials used in printing document data on a base material, and order of overlaying of the color materials during printing. The multiple print order and base material setter is configured to set at least one of a number of repetitions of printing based on the types of color materials and the order of overlaying of the color materials and a type of base material. The preview image generator is configured to generate a preview image simulating a print result of the document data on a basis of information set by the normal print order setter and the multiple print order and base material setter.

A correction coefficient calculation unit including a reference image output unit that generates a reference image, a profile receiving unit that receives image information and printing information, the image information indicating a color characteristic related to an image to be displayed on a display unit, the printing information indicating a color characteristic related to a printing device, and a reference image division unit that creates printing characteristic data that associates the reference image with the reference image that has undergone color conversion based on the printing information and the image information.

An image processing apparatus is caused to execute adjustment processing for an image; generate a soft proof image based on the image, a parameter adjusted in the adjustment processing, and characteristic information on a printing apparatus; display the soft proof image on a screen; and store the parameter of the adjusted image for which the adjustment processing is performed while the soft proof image is being displayed on the screen, and information relating to the printing apparatus, in association with the image.

A sheet tray includes: a tray body; first and second guides slidable on the tray body and contactable with a sheet; an interlocking mechanism; and a plate including first and second plate engaging portions. The first guide includes a first guide engagement portion and a first operation portion. The second guide includes a second guide engagement portion and a second operation portion. When the first operation portion and the second operation portion are located at non-operated positions, the plate is located at a first position where the first and second plate engaging portions are respectively engaged with the first and second guide engagement portions. When the first operation portion and/or the second operation portion is located at an operated position, the plate is located at a second position where the first and second plate engaging portions are respectively spaced apart from the first and second guide engagement portions.

A correction coefficient calculation unit includes: a reference image output unit that generates a reference image; a profile receiving unit that receives image information and printing information, the image information indicating a color characteristic related to an image to be displayed on a display unit, the printing information indicating a color characteristic related to a printing device; and a reference image division unit that creates printing characteristic data that associates the reference image with the reference image that has undergone color conversion based on the printing information and the image information.

An inspection apparatus includes a colorimetric value acquisition unit that acquires a colorimetric value of a patch positioned on a color chart, a decision unit that decides an approval status of the colorimetric value of the patch, on a basis of the colorimetric value of the patch and a reference value prepared for the patch, and a display processing unit that displays, on a display unit, a chart image simulating the color chart, and in which a color representing a patch image positioned in the chart image is displayed in a shape representing a decision result made by the decision unit.

An image effect processing support apparatus includes: an image effect processing section that performs a specific image effect processing on an image; a confirmation region determination section that determines an effect of the specific image effect processing for each part of the image, and based on a result of the determination, determines and sets a confirmation region for confirming the effect of the image effect processing; and a display control section that displays an effect indication that shows the effect of the image effect processing in the confirmation region on a display section, to thereby enable an effect of a filter effect processing to be easily confirmed.

An image processing device includes: a conversion relationship acquisition unit that acquires, for each of plural output destinations by which to output an image, a conversion relationship for performing color correction corresponding to each of the output destinations; a selection information acquisition unit that acquires, for each of the plural output destinations, selection information about whether or not to perform color correction using the conversion relationship; and an image data transmission unit that transmits, to a display device, image data expressing the image before or after performing color correction on a basis of the selection information acquired from the selection information acquisition unit.
