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.

Abstract: A device for correcting the recording density of a recording apparatus having a thermal head implemented as an array of a plurality of elements. The device corrects energy to be applied to the head on the basis of the resistance of each element and thickness data associated with a glaze layer.
