近年来,印刷领域作为情报化社会的一部分,已经取得了惊人的发展。即使说我们每天都生活在产品样本、宣传广告、报纸、书籍等印刷品的洪流中,也并非言过其实。另外,近十五年里,支撑着这一印刷领域发展的印刷技术及材料也发生着突飞猛进的变化。现在的印刷品,大部分是采用平版印刷的一种——胶版印刷,而在胶版印刷中,有95％是使用PS版。 In recent years, as a part of the information-based society, the printing industry has made amazing progress. Even if we say that we live everyday in the flood of prints such as product samples, advertisements, newspapers, books, etc., it is not exaggerated. In addition, in the past fifteen years, printing technology and materials that support the development of this printing sector have also undergone rapid changes. Most of the printed matter nowadays is one of lithographic printing—offset printing, and 95% of off-set printing uses PS version.
