<P>PROBLEM TO BE SOLVED: To provide a method, for controlling a blanket, which is intended for improving the printing quality of an ink pattern and maintaining printing productivity by absorbing an ink solvent absorbed into the blanket at appropriate timing, and a printing device. <P>SOLUTION: This printing device comprises (1) the blanket 11, (2) a solvent absorbing means 15 for absorbing the ink solvent of the blanket, (3) a solvent concentration measuring means for measuring an ink solvent concentration in the blanket, (4) a concentration distribution measuring means for measuring the concentration distribution of the ink solvent in the thickness direction of the blanket, and (5) at least one measuring means selected from the group consisting of ink pattern measuring means for measuring the size of an ink pattern etc. Further, with the use of this printing device, the conditions to execute the process for absorbing the ink solvent are decided based on at least one of the measurement results obtained from each one of the measuring means, and preferably under fuzzy control. Next, the swelling condition of the blanket is properly controlled by controlling the solvent absorbing means 15. <P>COPYRIGHT: (C)2007,JPO&INPIT |
