数码制卡专用基片及其制备方法发明领域 Special substrate for digital card making and preparation method thereof

本发明涉及数码制卡领域，尤其涉及一种数码制卡专用基片及该基片的制备方法，本发明还涉及使用该基片制作的数码印制卡片。发明背景 The present invention relates to the field of digital card manufacturing, and in particular, to a special substrate for digital card manufacturing and a method for preparing the substrate. The present invention also relates to a digital printed card made using the substrate. Background of the invention

目前国内外供彩色喷墨打印的基材很多，主要应用于打印彩色照片、广告、幻灯片等，但进行彩色喷墨打印的制卡专用基材却鲜有报道。各种卡片，包括名片（卡）、银行卡、各种名目的会员消费卡和用于展示企业或个人特点的卡片的使用日益增多，这些卡片中除名片多采用纸质，其它种类的卡片多为塑料材质（PVC )，直接在基材上印刷图文制成卡片，而胶印制卡是长期以来的主要制作方法，该方法需要通过胶片制版后再印刷，成本高，工艺繁琐，一般要求批量作业，不适合制作个性化卡片和短版制卡业务，难以满足个性化卡片的印制要求。目前的个性化卡片的印制方法主要是热升华和数字彩印，热升华的打印分辨率一般只有 360dpi，制作的图文清晰度低，图案的耐久性不好，而且效率低，成本高。数字彩印制卡的分辨率只有 300dpi，卡片图案色彩偏灰暗，印制网线明显可见，清晰度指标低。这些印制效果上的不尽人意之处都与基片的材质和性能有很大关系，目前常见的单层结构 PVC材质基片尤其不适用于喷墨打印机制卡。发明概述 At present, there are many substrates for color inkjet printing at home and abroad, which are mainly used to print color photos, advertisements, slides, etc. However, there are few reports of special substrates for color inkjet printing. The use of various cards, including business cards (cards), bank cards, membership cards of various names, and cards used to show corporate or personal characteristics, is increasing. These cards are mostly paper, except for business cards. It is made of plastic (PVC), and the graphics are printed directly on the substrate to make cards. Offset printing cards have been the main manufacturing method for a long time. This method requires printing through film making. The cost is high, the process is complicated, and batches are generally required. The operation is not suitable for making personalized cards and short-form card making business, and it is difficult to meet the printing requirements of personalized cards. The current printing methods of personalized cards are mainly sublimation and digital color printing. The printing resolution of sublimation is generally only 360dpi, the produced graphics have low definition, the durability of the pattern is not good, and the efficiency is low and the cost is high. The digital color printing card has a resolution of only 300dpi, the color of the card pattern is dark, the printed network lines are clearly visible, and the sharpness index is low. These unsatisfactory printing effects have a lot to do with the material and performance of the substrate. The currently common single-layer structure PVC substrate is not particularly suitable for inkjet printer business cards. Summary of invention
