摘要： An image forming apparatus performs printing of only a special color area by extracting an area to which a special color ink is to be applied or an area to which a decorative printing, such as a texture, is to be performed and not applying ink on an area other than the extracted area. In this way, it is possible to reduce an ink amount in test printing while checking tint of the special color area by performing printing also using inks other than the special color ink for the printing of the special color area.

摘要： A display processing apparatus perform display processing of a preview image showing a result of image formation of document data in an image forming apparatus. The document data includes color plane image data and transparent plane image data. The color plane image data includes a plurality of drawing areas and indicates an area for which use of a color developer in the image forming apparatus is specified. The transparent plane image data indicates an area for which use of a transparent developer in the image forming apparatus is specified together with a type of transparent processing performed on the area by using the transparent developer in units of the drawing areas. The display processing apparatus includes a transparent display data generating unit, a preview image generating unit, and a display control unit. The transparent display data generating unit generates, based on the document data, a plurality of pieces of transparent display data that show a result of image formation corresponding to the transparent processing performed with the transparent developer on the drawing areas on which the same transparent processing is performed for each type of the transparent processing. The preview image generating unit arranges a color display plane on which the color plane image data is displayed at a predetermined position of the color display plane in the preview image and arranges in a superimposed manner a plurality of transparent display planes on which the pieces of transparent display data are displayed at a plurality of positions of the transparent display planes that are determined based on the position of the color display plane in accordance with a predetermined rule and that are different from one another, so as to generate the preview image obtained by projecting the color display plane and the transparent display planes that are arranged in a three-dimensional space onto a two-dimensional plane. The display control unit displays the preview image on a display screen.

摘要： A printer is disclosed. The printer is calibrated for use with colored media. The printer is calibrated by converting an original color look up table (CLUT) for use on any colored media to a modified CLUT for use on colored media with a measured color. Each of a plurality of output colors in the original CLUT are modified using the measured color of the media.

摘要： A method for processing a rasterized relief image, comprising customary colour channels for indicating a colour of each pixel and a height channel for indicating a height of each pixel into several pass images that are printed using a printer with several colorants including a white colorant. For each pixel a relief part, a white part and a skin part are discriminated in order to combine the demands for height and colour variation across the surface of the image. The skin part comprises pixels for which a colorant composition based on the colour channels of the rasterized relief image is established. In order to print a colour in the skin part that is independent of a height of the pixel and independent of the colorant composition of a neighbouring pixels, pass images are composed that include only neighbouring pass pixels that do not disturb the colour forming of a pass pixel contributing to a skin part.
摘要翻译：一种用于处理光栅化浮雕图像的方法，包括用于指示每个像素的颜色的常规颜色通道和用于将每个像素的高度指示为使用包括白色着色剂的多种着色剂的打印机打印的多个通过图像的高度通道。对于每个像素，鉴别浮雕部分，白色部分和皮肤部分，以便组合对图像表面的高度和颜色变化的要求。皮肤部分包括基于光栅化浮雕图像的颜色通道的着色剂组合被建立的像素。为了在皮肤部分中打印与像素的高度无关并且与相邻像素的着色剂组成无关的颜色，通过图像被构成为仅包括不干扰通过的颜色形成的相邻通过像素像素有助于皮肤部位。

摘要： A printing system and method of printing an object having a surface (36) of varying height, by a printer configured to print a number of pass images (1; 2; 3; ...) on top of each other in a number of passes, including: deriving (S12) from an object image a number of pass images (1; 2; 3; ...) to be printed on top of each other, including: establishing (S28; S40) pass pixels of the pass images for which pass pixels a pass pixel height is defined, wherein a sum of the defined heights of a sequence of pass pixels that corresponds to a respective pixel (A; B) of the object image equals the height of that pixel of the object image; and printing the pass images (1; 2; 3; ...) on top of each other. An amount of printed material that is printed per printed pass pixel is varied in accordance with the defined pass pixel heights. The pass pixels heights are selected S26), based on random data, from a respective set of at least two positive pass pixel heights.
