Printing unevenness caused in forming a polarizing film by printing an ink liquid having a dichromatic dye is minimized to provide satisfactory LCD display characteristics. Bearings are erected on opposite sides of a table and are formed with vertical slots, into which the opposite ends of an axle of a printing cylinder are dropped, whereby the axle of the printing cylinder is loosely fitted in the right and left bearings. The bearings are horizontally movably constructed and connected to a horizontal motion drive (not shown). Further, right and left weights of equal heaviness are attached to the opposite sides of the axle of the printing cylinder. In producing a polarizing film, a substrate is placed on the table and a format having a number of fine grooves is attached to the printing cylinder and placed on the substrate. Ink liquid having a dichromatic dye is applied to the format to form a thin film of ink liquid on the format surface, and the bearings are horizontally moved along the printing direction. Thereby, the printing cylinder rolls on the substrate, so that the thin film of ink liquid is transferred from the format to the substrate.
