Printing apparatus

摘要

A method of applying a control strip having an appropriate size in accordance with the size of a print image is provided. Print image data is rasterized or RIP-processed in Step S 1 . Image layout data is acquired from the print image data in Step S 2 . The size of control strip image data is adjusted based on the image layout data in Step S 3 . The size of the control strip is determined to be a positive integral multiple of an ink key size, based on a previously established equation. Based on the size of the control strip image data, a previously prepared control strip having a maximum size is cut. The adjusted control strip image data and the print image data are combined together in Step S 4 . In Step S 4 , blank data are added to the left and right of the print image to extend the size of the print image to the size of the control strip.
