Dual-purpose coated paper, which enables in-line inkjet printing with web offset, can be used for both offset and inkjet prints. This product has potential to meet the ever-increasing demand for printing individualized information on commercial printing materials. In this work, commercial samples were printed in the two presses. It was deduced that low permeability correlates with large color gamut volume. The correlation would be useful to design coating formulations for good printability. Also, we examined the packing of coating layers to identify a coating formulation that provides good printing quality in both offset and inkjet printing. Many combinations of pigments were tested, and the effects of particle shape on viscosity and packing were examined. For all coating colors, pigment mixtures with a weight ratio of 3:1 gave the highest packing density. The mixture of GCC 90 and delaminated clay with a weight ratio of 3:1 was the best selection studied for dual-purpose coated paper. Among commercial paper samples, a web offset coated paper showed the best overall performance, indicating that coating formulations with minimal blistering are suitable for dual-purpose coated paper.

两用涂布纸的最佳颜料涂料

两用涂布纸可以进行带卷筒纸胶印的在线喷墨打印,可用于胶印和喷墨打印。该产品有潜力满足在商业印刷材料上印刷个性化信息的不断增长的需求。在这项工作中,在两台印刷机上印刷了商业样品。可以推断出低渗透性与大色域体积有关。该相关性对于设计涂料配方以获得良好的可印刷性将是有用的。此外,我们检查了涂层的填充情况,以确定在胶版印刷和喷墨印刷中均能提供良好印刷质量的涂料配方。测试了颜料的许多组合,并检查了颗粒形状对粘度和堆积的影响。对于所有涂料,重量比为3的颜料混合物 1给出了最高的堆积密度。重量比为3:1的GCC 90和分层粘土的混合物是两用涂布纸研究的最佳选择。在商业纸样品中,卷筒纸胶印铜版纸表现出最佳的整体性能,这表明起泡最少的涂料配方适用于两用铜版纸。
