Title:
THERMAL TRANSFER RECORDING SHEET AND PRODUCTION THEREOF
Document Type and Number:
WIPO Patent Application WO/1988/006101
Kind Code:
A1
Abstract:
Rewinding and detecting end marks (3, 3A) by a light-reflecting ink are gravure-printed near the trailing end of a thermal transfer recording sheet (1) produced by disposing a heat-fusible ink layer (1b) on the surface of an elongated base film (1a). The gravure-printed end marks have a uniform thickness and their edges are sharp. Therefore, reliability of sensing by a reflected light sensor can be improved. To print the end marks (3, 3A) by the gravure printing system, a wide sheet (S) is fed through a printing unit (30) of a gravure printing press (16) and immediately after printing of a plurality of parallel end marks, only the end marks are dried. During the same feeding step, the wide sheet (S) is cut into narrow thermal transfer recording sheets (1) by a slitter (17) in such a manner that each sheet contains respective end marks and taken up as rolls (16).
