Abstract:
1. A printing device which includes a transfer roller and a supporting unit for supporting a target substrate to be printed and wherein the printing device prints a printing pattern formed on the transfer roller onto the target substrate by rotating the transfer roller on the target substrate, the printing device further comprising: an imaging unit configured to obtain an image of a surface of the target substrate which has another printing pattern printed thereon; an image distortion processing circuit configured to extract a linear distortion component from the image and adjust a pressing amount of the target substrate against the transfer roller based on the extracted linear distortion component; and an adjusting mechanism configured to transfer, when the transfer roller is rotated on the target substrate, the printing pattern formed on the transfer roller onto the target substrate by pressing the target substrate based on the adjusted pressing amount, wherein a reduction ratio of the transferred printing pattern formed on the target substrate relative to the printing pattern formed on the transfer roller varies, along a rotating direction of the transfer roller, depending on the adjusted pressing amount.
