摘要

It is proposed that the known heat-set printing process for planographic and relief printing should be improved by the use of a short ink mechanism with an engraved roller and ink-scraping device and a printing ink which is solid at room temperature and can be liquefied by heating, and by ensuring that the ink-scraping unit and ink-conducting components of the printing system are set to a temperature above the liquefaction temperature of the printing ink. This prevents the production of waste gas and eliminates the danger of harmful and/or explosive vapour/air mixtures; obviates the need for facilities for drying the ink and processing the waste gases; and reduces energy consumption and the emission of carbon dioxide, heat and combustion by-products.
