Printing device and printing method

A printing device configured to produce a bendable printed matter, the printing device comprising:

• a printing head configured to discharge a liquid to a medium having flexibility;
• and
• a control unit configured to control liquid discharge by the printing head, wherein
• the control unit acquires bending information including information of a bending region, the bending region being a region to be bent in the medium, and information of a direction of the bending,
• the control unit is configured to execute a first print mode in which printing is performed based on the bending information and a second print mode in which printing is performed differently from the first print mode,
• in a case of printing, in a printing region including the bending region of the medium, an image at least partially continuous in the direction of the bending, the control unit makes coverage by a dot of the liquid discharged by the printing head to the bending region when printing the image in the first print mode lower than coverage by a dot of the liquid discharged by the printing head to the bending region when printing the image in the second print mode, and
• in the first print mode, the control unit forms a slit in the bending region, the slit being a dot-off region that is continuous in an intersecting direction intersecting the direction of the bending and in which no dot is printed.
