水披覆转印的研究进展

水披覆转印工艺包括水转印膜的制作、水转印和后处理3个部分,主要材料有载体薄膜、印刷油墨、油墨活化剂及底漆与面漆,其印刷方式一般采用传统的凹版印刷。水披覆转印的载体薄膜一般为水溶性PVA薄膜,油墨通常为溶剂型油墨,活化剂主要是以芳香烃为主的有机混合溶剂。以水性油墨替代溶剂型油墨、无毒活化剂替代有毒或微毒活化剂、彩色喷墨印刷方式替代传统的凹版印刷方式等绿色环保、生产效率高的水披覆转印技术是今后水转印技术的研究方向与重点。

The Advance in Study on Water Bestrow Transfer Printing

Water bestrow transfer procedure mainly includes water transfer film production, water transfer and post-processing. Carrier film, printing inks, activator, primer and topcoat are the main materials of transfer printing, while traditional gravure printing is generally used in the transfer process. The carrier film of water bestrow transfer printing is generally water-soluble PVA film, the ink is usually solvent-based ink, and activator is the aromatic hydrocarbon-based organic mixed solvent. The water bestrow transfer is environmental friendly and highly efficient. Adopting water-based ink, non-toxic activator and color inkjet printing will be the direction and focus in future researches.
