摘要:
The occurrence of offsetting and strike-through in a stencil printing device is prevented without creating any new problems, and the printing paper is allowed to be conveyed with a pair of rollers interposing the printing paper for a reliable paper ejection process. Printing paper P is passed through a nip between a contact roller 37 and a counter roller 39 opposing the contact roller 37, the outer circumferential surface of the contact roller being coated with a layer of excess ink removing liquid which does not dissolve with the printing ink forming the printed image and has smaller surface tension than the printing ink, and the contact between the excess ink removing liquid layer a of the contact roller 37 and the printed surface of the printing paper P causes the excess portion of the printing ink b deposited on the printed image of the printing paper to be transferred onto the excess ink removing liquid layer a so as to remove the excess ink from the printing paper P. The contact roller may be replaced with an endless contact belt 83.
