Abstract

Direct thermal printing is a relatively old technology and has been used in hardcopy printing for many years. In this process, heat from a thermal print head causes a transparency or reflection change on a thermally sesitized film or paper. The modern thermoprinters use contact recording method and forms the image with help of thermal print head -linear array of small heating elements. The resolution and time of output process are limited by the heating element size (2 to 10 per mm) and time delay for heating ofthe thermohead element up to temperature of thermal media modification which leads to change of transparency or reflection.' The problem of resolution and time delay may be effectively solved by application of a focused laser beam as a non-contact heating source. This paper deals with the investigation of standard thermal materials on transparent and reflective substrates as a recording media in the process of laser thermal recording. As usual, such kind of materials are used for hard copies output in the process of direct thermal imaging on thermal printers. The paper describes the results ofthe test records on transparent and reflective thermal media samples on polymer and paper substrates.
