Description

一种全UV无缝模压印刷工艺 技术领域
本申请涉及模压印刷技术领域，尤其是涉及一种全UV无缝模压印刷工艺。
 背景技术
模压全息术，又称“全息印刷术”，是一门高科技印刷工艺；由于其制得的全息图文集防伪、美感于一体，该技术被广泛应用于防伪标识、印刷出版物、包装装潢等领域。
相关行业中，进行全息模压印刷时，通常将镭射版卷贴于模压版辊上，通过加热模压方式或UV模压方式，将镭射版上的镭射信息转移到薄膜基材上。但是，由于镭射版卷贴不可避免地存在拼接版缝，使得生产出的全息模压产品图文不连续。目前，利用加热模压方式进行全息模压印刷时，为补偿拼接版缝对印制图文的影响，模压设备通常设置前后两组模压版辊，版辊内部1/4宽度通冷却水、3/4通导热油；然后，将镭射版卷贴于模压版辊上，并使拼接版缝位于1/4冷却处；薄膜基材经第一组版辊模压后，3/4部位有镭射图案，余下1/4无镭射；随后，薄膜基材再经第二组版辊模压，第二组版辊3/4加热处镭射图案对第一组图案的1/4无镭射处进行覆盖，以此实现对镭射图文的连续印刷。
针对上述中的相关技术，发明人认为，由于版辊冷区与热区的过渡部分存在暗区，暗区部位镭射亮度与非暗区部位存在一定差异，致使薄膜上对应版缝的两边均出现暗影，同样影响印刷品质量，存在待改进之处。
 发明内容
为了改善镭射版拼接版缝对印刷品质量的影响，本申请提供一种全UV无缝模压印刷工艺。

优选的，S3-1之后，设置第一展平辊组对薄膜基材进行展平。
通过采用上述技术方案，利用第一展平辊组对薄膜基材进行展平，有助于提升薄膜基材表面涂覆UV涂料的均匀性，从而保证后续镭射信息转移至薄膜基材上的完整性，进而提升UV镭射膜的良品率。
