    • PURPOSE: A method for printing and fixing patterns on both sides of a foamed sheet made of synthetic resin is provided which has good productivity and can be applied variously as needed, and additionally has an advantage that a printed matter prepared by the method is hardly peeled off. CONSTITUTION: A method comprises the following steps: a step of printing patterns on one side of a foamed sheet (1) made of synthetic resin such as polystyrene resin and polyethylene resin, by passing the sheet through a printing part equipped with a printing roller (5), a bowl for printing ink (2), printing ink (3), a roller for supply of printing ink (4) and a supporting roller (7); a step of drying the patterned sheet, by passing the sheet through a drying part equipped with blowers (8) and (8a); a step of coating the dried sheet and fixing the patterns printed on the sheet, by passing the sheet through a coating part consisting of dropping a clear synthetic resin solution (9) on the sheet and compressing the synthetic resin-coated sheet with a cooling roller (c); a step of converting the sheet, by passing the sheet through a converting part; and a step of printing patterns on the other side of the sheet using the same method as the above and drying, coating and fixing the patterned sheet using the same method as the above, wherein the sheet is transported by means of several guide rollers through the whole processes.
    • 目的:提供一种由合成树脂制成的发泡片材的两面印刷和固定图案的方法,其具有良好的生产率并且可以根据需要进行各种应用,另外具有通过该方法制备的印刷品几乎不被剥离 关闭。 方案:一种方法包括以下步骤:通过将片材通过配备有印刷辊的印刷部分(例如聚苯乙烯树脂和聚乙烯树脂),由诸如聚苯乙烯树脂和聚乙烯树脂的合成树脂制成的发泡片材(1)的一面上印刷图案的步骤 5),用于印刷墨水的碗(2),印刷油墨(3),用于供应印刷油墨的辊(4)和支撑辊(7)); 通过使片材通过配有鼓风机(8)和(8a)的干燥部件来干燥图案化片材的步骤; 通过将片材通过将透明合成树脂溶液(9)滴加在片材上的涂布部分,并用冷却辊压缩合成树脂涂布片材的步骤,涂布干燥片材并固定印刷在片材上的图案 (C); 通过将片材通过转换部分来转换片材的步骤; 以及使用与上述相同的方法在片材的另一侧上印刷图案的步骤,并使用与上述相同的方法干燥,涂布和固定图案化片材,其中片材通过几个导辊通过 整个过程。
