In this research study, the applicability of polycaprolactone‐silicon dioxide and polycaprolactone‐zinc oxide coatings used as primers on papers for offset printing, was analysed. Polycaprolactone nanocomposites with different concentrations of nanoparticles were prepared and coated onto three types of papers: uncoated, low‐coated and gloss. The main aim was to analyse the influence of the nanoparticle concentration in primer on the optical and colorimetric properties of cyan and magenta offset printed samples. To further evaluate the applicability of the primers, the tensile strength of primed samples and their surface properties were analysed. Results show that prepared primers are primarily applicable on uncoated and low coated papers. Both nanoparticles in specific concentrations increased gloss values for printed samples on low‐coated paper, and the addition of both types of nanoparticles increased the rub resistance of printed samples. Furthermore, for each type of nanoparticle, the optimal concentration at which the colour deviation on print was minimised could be defined. Adding nanoparticles to primers did not significantly improve mottling on cyan‐printed samples. However, by increasing the concentration of nanoparticles in the primer by up to 1%, the mottling on magenta‐printed samples decreased.

用于纸张基材的带有氧化锌和二氧化硅纳米粒子的聚己内酯底漆：对青色和品红色胶印印刷性能的影响

在本研究中，分析了用作胶版印刷纸上底漆的聚己内酯-二氧化硅和聚己内酯-氧化锌涂料的适用性。制备了具有不同纳米粒子浓度的聚己内酯纳米复合材料，并将其涂布在三种类型的纸张上：未涂布纸，低涂布纸和光泽纸。主要目的是分析底漆中纳米颗粒浓度对青色和品红色胶印样品的光学和比色性能的影响。为了进一步评估底漆的适用性，分析了底漆样品的拉伸强度及其表面性质。结果表明，制备的底漆主要适用于未涂布纸和低涂布纸。两种特定浓度的纳米颗粒均可提高低涂层纸上印刷样品的光泽度，两种类型的纳米粒子的加入增加了印刷样品的耐摩擦性。此外，对于每种类型的纳米颗粒，可以定义使印刷时的颜色偏差最小的最佳浓度。在引物上添加纳米颗粒并不能显着改善青色打印样品上的斑点。但是，通过将底漆中的纳米颗粒浓度提高多达1％，洋红色打印样品上的斑点减少了。
