Patent ID: 8752928

Claim:
A print data generation device comprising: an image data acquisition unit configured to acquire image data; and a print data generation unit configured to cause a printer to perform a printing action of printing a line during an N th (N being a natural number of 2 or greater) main scan between other lines printed during an N−1 th main scan and printing a print unit including a plurality of lines during the N−1 th main scan to an Nmax th (Nmax being a maximum value of N) main scan, the Nmax th main scan being a final main scan performed to print the print unit, and to generate print data for controlling the amount of ink discharged from a print head so that the amount of ink discharged based on the same tone value of the image data during the Nmax th main scan is greater than the amount of ink discharged based on the same tone value of the image data during each of the Nmax−1 th main scan and earlier main scans, the earlier main scans being earlier than the Nmax−1 th main scan and preformed to print the print unit, and for causing the printer to print an image indicated by the image data, the print data being generated based on the image data; each of the lines being printed by one main scan.
