Abstract
In an ink jet printer, formation time of processing for generating data for providing a treatment liquid for improving fixing or water resistance of an ink by insolubilizing or coagulating a color material in the ink is reduced. For this purpose, to perform HV conversion for raster data for image data related to printing, processing for temporarily storing image data and processing of rewriting the HV conversion result are performed in a same sequence. For example, a treatment liquid data formation register having the same structure as an HV conversion register is provided. This register is masked to a pattern according to a treatment liquid composition on a printing medium and is made corresponding to data bits of the HV conversion register. Print data accessed by the HV conversion register is located in relation to the access, thereby forming the treatment liquid data simultaneously.
