IPC: B41F7/24
Filed: 1988-11-24
Abstract: PURPOSE:To realize stable printing through the supply of dampening water of a necessary amount to every position by adjusting for every water amount adjusting member a gap between said member and the surface of a first dampening roller. CONSTITUTION:The water in a water tank 3 is adhered to the surface of a first dampening roller 4 subsequent to the rotation of the roller 4, and moved to a blade 8. When the water passes this part of the blade 8, a water film having a thickness corresponding to a gap between each array of the roller 4 and the blade 8 is formed at the array corresponding to the blade 8. This water is moved from the roller 4 to a dampening roller 5, and further to a form roller 1. Since the roller 4 is made of metal or ceramic, the thickness of the water film is correctly corresponding to the gap between the array and the blade. Therefore, if the gap is adjusted for every array of the roller, the amount of the dampening water can be adjusted for every position in a lengthwise direction of the form roller 1.
