喷墨打印 CTP技术是利用喷墨打印设备在金属版基或聚合物版基上直接喷涂影像 的技术。 制版的金属版基可以使用锌版、 铜版或铝版。 为了使金属版基的耐印力及分辨 力提高， 通常要对金属版进行砂目化处理（见 CN85100875 ), 使金属版基表面具有一 定的粗糙度。 目前砂目化处理方法可分为阳极氧化方法和未经阳极氧化的方法。 阳极氧 化工艺比较成熟， 使用较为广泛， 一般阳极氧化后的金属版基表面的粗糙度的参数 Ra=0.6〜0.9 m (Ra为高度参数轮廓算术平均偏差）。 但为避免大量的酸、 碱废液对环 境易造成较大污染、 版材整体的造价提高， 还可以采用未经阳极氧化的方法对金属版基 进行处理。
