Title:
A printing method and a printing system
Document Type and Number:
Japanese Patent JP6210319
Kind Code:
B2
Abstract:
A method for determining a color profile from received raster data and printing the raster data is provided. Color profiles provide a mapping from a color space of the raster data to a color space of the printer, which typically uses CMYK toner or ink. A text color profile may be employed to print crisper text, or a photo color profile may be employed to produce better images. The raster data includes a plurality of raster scan lines containing digital pixel values. The method includes determining a number of sequentially repeated digital pixel values (906, 908, 912, 914) and a number of sequentially non-repeated digital pixel values (906, 910, 912, 914) for the plurality of raster scan lines. A color profile is selected (918, 920) based on a determination between the repeated and non-repeated digital pixel values (916). An example image forming apparatus that may carry out the method is also provided.
