Abstract:
1. A dot data generating method using a first inkjet recording device and a second inkjet recording device, each of which conducts printing of an image by ejecting ink drops from an inkjet head and forming dots of various sizes on a recording medium while relatively moving the inkjet head with respect to the recording medium, with the inkjet head being able to form dots of a plurality of types of sizes on a recording medium, in which a first image is printed using the first inkjet recording device by ejecting ink drops from the inkjet head onto the recording medium based on first dot data which determines formation or non-formation of dots and sizes of dots, and second dot data is generated to print a second image by ejecting ink drops from the inkjet head onto another recording medium based on the second dot data using the second inkjet recording device in which ejected ink drops land onto a recording medium with a small degree of dispersion in a relative movement direction compared to the first inkjet recording device, the dot data generating method comprising: generating the second dot data by converting the first dot data such that data of each dot in which at least a maximum dot size is determined is converted so as to form a plurality of dots having sizes smaller than the maximum dot size at predetermined intervals between the dots in the relative movement direction in place of the each dot.
