Printed image after-processing apparatus

摘要

A printed image after-processing apparatus (29) includes a contact member (37) adapted to be rotationally driven and coated with an excess ink removing liquid incompatible with a printing ink forming a printed image on a printed sheet (P), the liquid having a surface tension lower than that of the printing ink. A counter member (39) having a center line surface roughness of 0.5 mu m or less is provided for feeding said printed sheet (P) after printing between said counter member (39) and said contact member (37) thereby to make the printed surface of said printed sheet (P) contact the contact member (37). Supplying means (47) is provided for supplying the excess ink removing liquid to the contact member (37) as well as cleaning means (45) which is kept in contact with said contact member (37). <IMAGE>
