Abstract
An ink reduction rate is set in accordance with the type of image and the type of recording medium. For example, when a photograph is to be printed on a glossy paper with low resolution, the ink reduction rate is set to 10%. When a photograph is to be printed on a plain paper with low resolution, the ink reduction rate is set to 25%. When a document is to be printed with low resolution, the ink reduction rate is set to 50%, irrespective of the type of recording paper.
Claims7
A non-transitory computer readable storage medium storing a data processing program for controlling a computer to perform steps comprising:
- a) inputting data;
- b) determining an ink reduction rate based on the type of recording medium onto which the data is to be printed;
- c) acquiring a lightness value and a saturation value by converting the data;
- d) acquiring a saturation modification value and a lightness modification value based on the ink reduction rate;
- e) modifying the lightness value into a modified saturation value based on the lightness modification value, and modifying the saturation value into a modified saturation value based on the saturation modification value;
- and
- f) calibrating the data based on both the modified lightness value and the modified saturation value.
A data processing device comprising:
- an inputting unit configured to input data;
- a determining unit configured to determine an ink reduction rate based on the type of recording medium onto which the data is to be printed;
- a first acquiring unit configured to acquire a lightness value and a saturation value by converting the data;
- a second acquiring unit configured to acquire a saturation modification value and a lightness modification value based on the ink reduction rate;
- a modifying unit configured to modify the lightness value into a modified lightness value based on the lightness modification value and modify the saturation value into a modified saturation value based on the saturation modification value;
- and
- a calibrating unit configured to calibrate the data based on both the modified lightness value and the modified saturation value.
