Print control apparatus and print control program for printing with special color ink

摘要

A print control apparatus includes an image data acquisition unit for acquiring at least first image data of a raster format that defines color information and second image data of a raster format that defines an amount of recording with a special color ink different from the color that is indicated by the color information, a PDL data generation unit for generating PDL data with which an instruction for printing a document comprising at least an image represented by the first image data and the second image data is described by a page description language, and a transfer unit for transferring the generated PDL data to a print unit, wherein the PDL data generation unit generating a command for designating a method of printing for the special color ink represented by the second image data and generating PDL data that includes the generated command.

1. A print control apparatus comprising:
an image data acquisition unit configured to acquire at least first image data of a raster format that defines color information and second image data of a raster format that defines an amount of recording with a special color ink different from the color that is indicated by the color information; a PDL data generation unit configured to generate PDL data indicative of an instruction for printing a document comprising at least an image represented by the first image data and the second image data; and a transfer unit configured to transfer the generated PDL data to a print unit, the PDL data generation unit being configured to generate the PDL data by
compressing the first image data by a predetermined method of compression,making a determination as to whether the second image data is converted into one of a first PDL format and a second PDL format, which is different from the first PDL format, in accordance with the content of the second image data, the second PDL format corresponding to a command for designating a method of printing for the special color ink represented by the second image data,converting the second image data into the one of the first PDL format and the second PDL format according to the determination, andgenerating the PDL data including the first image data compressed by the predetermined method of compression and the second image data converted into the one of the first PDL format and the second PDL format, wherein the PDL data determination unit makes the determination in accordance with the number of ranges where the special color ink is recorded in the second image data such that the second image data is converted into the second PDL format when the number of ranges is not greater than a threshold value.
