Inkjet printing device and printing method for printing an image on a continuous medium

An inkjet printing device comprising:

• a medium transport mechanism that transports a continuous medium in a medium transport direction;
• an inkjet head that prints a user image on the continuous medium;
• one or more processors;
• and
• one or more memories that are connected to the one or more processors and store commands which are able to be executed by using the one or more processors, wherein:
• the one or more processors read out the commands from the one or more memories and print non-product image position information including information on a position of a non-product image printed on the continuous medium in the continuous medium;
• the non-product image is constituted of at least one of ink of dummy jet or a jetting state monitoring pattern received from the inkjet head;
• and
• the non-product image position information is stored in the one or more memories according to image data of the non-product image, and is printed in a termination region of a print job in the medium transport direction and at a position on a downstream side of a region in which the non-product image is printed in the medium transport direction.

A printing method comprising:

• transporting a continuous medium in a medium transport direction;
• printing an image on the continuous medium by using an inkjet head;
• and
• printing non-product image position information including information on a position of a non-product image formed on the continuous medium in the continuous medium, wherein:
• the non-product image is constituted of at least one of ink of dummy jet or a jetting state monitoring pattern received from the inkjet head;
• and
• the non-product image position information is stored in one or more memories according to image data of the non-product image, and is printed in a termination region of the continuous medium in printing of the image and at a position on a downstream side of a region in which the non-product image is printed in the medium transport direction.
