Abstract

PURPOSE: To ensure uniform transfer even when a manufacturing tolerance of a thermo-pressing head is relatively large by a method wherein formation of a substance to be transferred for which inking is conducted by a thermal transfer type print image point heat transfer unit is conducted at least on a surface being soft helpfully. CONSTITUTION: By reading print image information from a print image storage device 12, a control unit 9 supplies energy selectively to a plurality of heating members 6 provided in a thermo-pressing head 7 and thereby a part 14a of a substance 14 to be transferred which is laminated on the surface of a thermal transfer sheet 13 is formed on the surface of a plate cylinder 4. The plate cylinder 4 has a soft layer fitted on the surface and, therefore, manufacturing tolerances of the pressing head 7, a guide head 8 and the plate cylinder 4 need not be precise. An ink image on the plate cylinder 4 is transferred onto a printing material web 3 passed between this cylinder and an impression cylinder 1, through the intermediary of a rubber blanket cylinder 2. In this way, uniform transfer of the substance to be transferred can be ensured.

Within a thermopressure head system - a thermal transfer sheet - the plate cylinder is subject to spacing variations and contact variations. That is, the pin electrode or heating member of the thermopressing head and the surface of the plate cylinder are both rigid and inelastic.
This is the case. If any shape displacement occurs in the members involved, no matter how small, this will have a negative impact on the effective pressing force and heat transfer, and may even result in unevenly transferred impressions or This will appear as a poorly fixed impression.
