适应不同承印物的UV喷墨油墨印刷适性

为了探讨在不同承印物上UV喷墨油墨印刷适性的差异,提高UV喷墨油墨在不同承印物上的印刷质量,选用铜版纸、玻璃卡标签纸、PVC塑料薄膜3种承印材料,分别用相同的UV喷墨油墨进行喷墨印刷,测试样张中线条的密度、模糊度、粗糙度、线宽、对比度等印刷质量指标;测量喷墨油墨在各承印材料上的接触角,结合其润湿情况,分析UV喷墨油墨在不同承印材料上的印刷质量。实验共制备10种不同表面张力与黏度的油墨进行喷墨印刷并测试印刷质量,采用综合分析评价方法评价其印刷质量。结果表明：在不同承印物上印刷时,UV喷墨油墨的印刷质量存在较大差异,实际生产中应根据所采用的承印物匹配相应印刷适性的UV喷墨油墨,以得到最佳印刷效果。

Study on the Printability of UV-curable Inkjet Ink on Different Printed Substrates

In order to research the differences of the printability of UV-curable inkjet ink on different printed substrates and improve the printing quality of UV-curable inkjet ink printing on different materials,this research select coated paper,glass card adhesive paper,PVC plastic film as printed substrates.After printing the same UV-curable inkjet ink,the printing quality indicators of printing proofs including the density of the line,blurriness,raggedness,line width and contrast of printing product lines were tested,and then test the contact angle of UV-curable inkjet ink on three printed substrates,combined with wetting situation,analysis the printing quality of UV ink-jet ink on different substrates,prepare UV ink-jet ink with different printability,printing and testing the printing quality,assessing the quality with comprehensive evaluation method.The result shows that it＇s existed large differences among the printing quality of the same UV-curable inkjet inks printing on different materials.We match the printed materials with the corresponding printability of UV-curable inkjet inks in the practical production,in order to get the best printing results.
