Variable digital optical images may be fabricated using generic optical matrices. A generic optical matrix may have a substrate and a plurality of pixels corresponding to color and sub-pixels corresponding to non-color effects. The pixels may include first pixels corresponding to a first color and second pixels corresponding to a second color. The sub-pixels may include first sub-pixels corresponding to a first non-color effect and second sub-pixels corresponding to a second non-color effect. Individual ones of the pixels and sub-pixels of the generic optical matrix may be obliterated according to a negative while remaining pixels and/or sub-pixels may be preserved. The remaining pixels and sub-pixels may form an optical image corresponding to a base image. The optical image may be colored based on the remaining pixels. The optical image may exhibit non-color effects corresponding to the remaining sub-pixels. The optical image may comprise a hologram or a stereo image.

In a case where image data for which brief spot color matching has been performed is stored by a BOX function, it is not possible to output the image data in correct color on a condition that the image data is transmitted to another device as it is. In a case where image data is stored by the BOX function, in a printer driver that generates PDL data therefor, a color matching method of type accompanied by the brief spot color matching is not allowed to be set.

An information processing apparatus includes a first acquiring unit that acquires a processing attribute of a printing process corresponding to a printing instruction for executing the printing process using print data, a second acquiring unit that acquires an apparatus attribute of an image forming apparatus that executes the printing process, a third acquiring unit that acquires a data attribute of the print data, a print data interpretation unit that performs an interpreting process for the print data based on the processing attribute, a request unit that requests the print data interpretation unit to perform the interpreting process according to the printing instruction when it is not possible to determine from at least one of the processing attribute, the apparatus attribute and the data attribute whether or not an error occurs in the printing process, and a controller that displays information indicating that the error occurs in the printing process.

An image processing device performs: breaking down a drawing command into horizontal line parameters each indicating a drawing parameter on a line-by-line basis; and reading, from a translucent image storage unit configured to store a translucent image including a translucency value indicating a transmission rate of a color value corresponding to pixel for each of a plurality of pixels, the translucency values of pixels corresponding to the horizontal line parameter, and writing color values designated by the horizontal line parameter directly into a color image storage unit configured to store a color image including a color value for each of a plurality of pixels as the color values of the respective pixels corresponding to the horizontal line parameter without reading the color values of the pixels corresponding to the horizontal line parameter from the color image storage unit, when all of the read translucency values indicate transparent.
