摘要： This invention relates to a method of inkjet printing, in particular for use in POS systems. In particular the printing method according to the invention is of the thermal type. In order to obtain high speed printing, for example of 15-20 lines per second when printing text on a paper medium 60-80 mm wide (for example receipts), the drops of ink ejected during the printing operation advantageously have a relatively large volume, i.e. not less than approximately 100 picolitres (pl) and preferably between 100 and 200 pl. The ink used for applications in POS systems must quickly penetrate an extensive range of paper media. This requirement is satisfied by using an ink having a surface tension of not more than approximately 35 dyne/cm (mN/m). Problems of stagnation and dripping of the ink caused by the printing conditions are overcome through the use of a nozzle plate coated with a wetting-resistant layer of silicon carbide. This coating material has proved to have non-wettability properties which do not significantly deteriorate during a printing operation over a long period of time.
摘要翻译：本发明涉及一种喷墨打印方法，特别是用于POS系统。特别地，根据本发明的印刷方法是热型。为了获得高速打印，例如在60-80mm宽（例如收据）的纸介质上打印文本时每秒15-20行，在打印操作期间喷射的墨滴有利地具有相对较大的容积即，不小于约100皮升（pl），优选在100和200pl之间。用于POS系统应用的墨水必须快速穿透各种纸张介质。通过使用表面张力不大于约35达因/厘米（mN / m）的油墨来满足这一要求。通过使用涂覆有耐碳化硅层的喷嘴板来克服由打印条件引起的墨水滞留和滴落的问题。已经证明该涂料在长时间的打印操作中具有不会显着劣化的非润湿性。
