Problems solved by technology

Therefore, when the last main scan is performed, the printing medium is elongated compared with the previous main scan, and the position of forming the line before the last main scan is shifted from the position of forming the line of the last main scan.

Embodiment approach

[0031] (1) The composition of the print data generation device:

[0032] figure 1 It is a block diagram showing the configuration of the computer 10 functioning as the print data generation device according to the present invention. The computer 10 is provided with the control part 20 and HDD30 which have RAM, ROM, CPU, etc., and the program memorize|stored in ROM, HDD30, etc. can be executed by the control part 20. In this embodiment, the print data generation program 21 can be executed as one of the programs. The print data generation program 21 has a function of causing the printer 40 to perform printing while preventing the printing medium from stretching and suppressing deviation of the line formation position. The printer 40 is connected to the computer 10 through an interface not shown.

Abstract

The invention relates to a print data generation device, which can suppress misalignment of a line formation position resulting from main scans being performed with different timings. A printer is made to perform a printing action of acquiring image data, printing a line during an Nth (N being a natural number of 2 or more) main scan between other lines printed during an N-1th main scan and earlier main scans, and printing a print unit made of a plurality of lines in Nmax (Nmax being the maximum value of N) main scans; and print data is created based on the image data, the print data controlling the amount of ink discharged from the print head so that the amount of ink discharged based on the same tone value of the image data is greater in the Nmaxth main scan than in the Nmax-1th main scan and earlier main scans and causing the printer to print an image indicated by the image data, the print data being generated based on the image data.

Description

technical field [0001] The present invention relates to a print data generating device for generating print data for causing a printer to perform printing. Background technique [0002] In an inkjet printer, by performing a main scan in which ink is ejected from each nozzle while moving a print head having a plurality of nozzles in a predetermined direction, a plurality of lines on a printing medium are printed, and the printing of the plurality of lines is completed. Thereafter, a sub-scan is performed to move the print head in a direction perpendicular to the above-mentioned predetermined direction, and printing is performed by repeating the main scan and the sub-scan. In addition, a technique has been developed in which, in order to realize high-resolution printing by printing dots at intervals shorter than the nozzle intervals, between lines printed by the main scan before N-1 Sub-main scanning prints lines (for example, refer to Patent Document 1).
