<p>PROBLEM TO BE SOLVED: To obtain an easy to see register mark in a pattern even when the pattern itself blacky in the case of outputting a pattern with register marks in a black/white output. SOLUTION: In the case of drawing register marks in an image (pattern), a rate of a black level in the register mark area is calculated (S3) and whether or not the rate of the black level exceeds the setting value is discriminated (S4). When the rate of black level does not exceed the setting value, the color of the register marks is selected to be black (S5) and when exceeded, the color is selected to be white (S6) respectively. Then the register marks are drawn in black or white and the results are stored in a page memory or the like and printed out by a printer as required.</p> |
