Abstract:
1. Printing control method for controlling a printing device that records ink drops of N types (N is an integer of 2 or greater) of different ink levels onto a printing medium under a plurality of printing conditions; wherein there is recorded onto a predetermined recording medium standard color conversion table data associating tone values of each of the plurality of color components in a predetermined color system with tone values of each of said ink colors, said table data being shared under said plurality of printing conditions; and plurality of sets of recording level specifying data indicating association relationships between tone values of each of said ink colors and recording levels which correspond to a plurality of different ink drop sizes of said N types of ink drops, said data having said recording level determined for each of said plurality of printing conditions in such a way that output color of each tone value is generally common under said plurality of printing conditions; the method comprising: creating recording level specifying data, the creating of the recording level specifying data including acquiring image data in which colors of pixels forming an image are represented by tone values of a plurality of color components in said predetermined color system; referring to said standard color conversion table to convert tone values of said image data into tone values for each ink color; selecting, from among said plurality of sets of recording level specifying data, recording level specifying data that matches the printing condition at the time printing is executed, and converting color-converted tone values to recording levels which correspond to a plurality of different ink drop sizes of said N types of ink drops; and carrying out printing of the converted recording levels which correspond to a plurality of different ink drop sizes.
