Dot data generating method, dot data generating device, inkjet recording device, and inkjet recording system

An inkjet recording system 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 while relatively moving the inkjet head with respect to the 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 a second image is printed by ejecting ink drops from the inkjet head onto another recording medium based on second dot data using the second inkjet recording device in which a speed of a relative movement of the inkjet head and a recording medium when printing an image is small compared to the first inkjet recording device, the inkjet recording system comprising:

• the first inkjet recording device;
• the second inkjet recording device;
• and
• a dot data generating device which generates the second dot data, and
• the dot data generating device including a data conversion section which generates the second dot data by converting the first dot data such that data of each dot in which formation of a dot is determined is converted so as to form a plurality of dots at predetermined intervals between the dots in a relative movement direction in place of the each dot.
