Abstract: A controller combines a code image created by encoding a paper ID and an image representing an electronic document, causes a printing unit to print the code image on a paper, causes a code-image reading unit to read the code image printed on the paper by the printing unit, acquires the paper ID, and collates the paper ID before encoding and the decoded paper ID. When the paper IDs do not coincide with each other or when the paper ID cannot be acquired, the controller causes an NG recording unit to perform NG recording on the paper and causes a paper-conveying-path switching unit to switch a discharge destination of the paper to a garbage tray and discharge the paper.

Abstract: An image recording apparatus for preparing a printing master film for textile printing includes an image recording unit including at least one thermal head for recording images on a recording material; a recording material transportation unit for transporting the recording material, including a platen roller for bringing the recording material into contact with the thermal head so as to for images or the recording material, and a back-up roller which is in pressure contact with the platen roller at an opposite position to the position where the recording material is brought into contact with the thermal heads by the platen roller; and a disk brake for controlling the rotation of the back-up roller, connected to the back-up roller.
