Title:
PRINTING METHOD OF INK-CIRCULATION TYPE
Document Type and Number:
Japanese Patent JPS6411832
Kind Code:
A
Abstract:

PURPOSE: To prevent the clogging with ink resulting from the hardening thereof, by automatically returning to an ink tank the ink overflowing a printing member which prints an object in contact therewith, thereby reducing the supplementing operation of organic volatile solvent into the ink tank.

CONSTITUTION: A printing ink within an ink tank 1 is, during printing, always continuously flowing to the side of an overflow ink tank 7 via a gate groove 8 provided in a grooved printing rod 6. Therefore, when a flat cable 4 which is an object to be printed is pressed against a printing groove 9 of the printing rod 6, the printing ink which is flowing at all times is adhered to an end portion of the flat cable 4. Further, the printing ink overflowing the grooved printing rod 6 which brings the printing ink into contact with the flat cable 4 is automatically returned into the ink tank 1 through the overflow ink tank 7, a pipe 12, a suction tank 11 for sucking the overflowing ink and a pipe 15.
