METHOD FOR OPERATING PRINTER AND INK UNIT

摘要

PROBLEM TO BE SOLVED: To enable a solid face with its space fully filled in to be printed readily and inexpensively. SOLUTION: An ink unit 3 has a screen roller 5 on its outer peripheral surface, which has patterns formed by recessed parts 11 capable of being filled with ink and rotates in cooperation with the roller 7. The screen roller 5 and the roller 7 are mutually adjusted and rotated, so that the patterns which are transferred onto the roller 7 by a printing media in a form of a printing media lump 15 every time the screen roller 5 rotates can be shifted slightly in the peripheral direction to the extent that the new printing media lump 15 can be arranged in a space 19 where no printing media exists or no printing media substantially exists between the adjacent respective printing media residual groups 17 relative to the pattern transferred on the roller 7 at the previous rotation of the screen roller 5.
