介绍了胶版印刷中印刷油墨的转移过程及颜料涂布纸的涂层结构的形成,阐述了涂层结构与印刷油墨固着的关系及涂布纸上Backtrap色斑的形成机理,指出涂层表面的物理和化学性质不“稳定”是引起Backtrap色斑的主要原因。
The transfer process of printing ink in offset printing and the formation of coating structure of pigment coated paper were introduced. The relationship between coating structure and printing ink fixing and the formation mechanism of Backtrap stain on coated paper were introduced. Physical and chemical properties are not “stable” is the main cause Backtrap stain.
