| 中文摘要: |
| 针对目前纸浆模塑包装制品有颜色单调、表面结构复杂、表观粗糙等局限，及产品外观粗劣、附加值低无法应用于高端产品包装等缺点，提出了采用丝网印刷的方式完成纸浆模塑包装制品表面印刷的方案。设计以纸浆模塑制品为承印物，以网印水基油墨、紫外线光固油墨、电子束辐射固化油墨为实验油墨，通过不同的印刷速度、印刷压力、网版间距进行表面印刷，并对纸浆模塑包装制品进行表面印刷效果测试评估，从而确定最适合的工艺参数。实验结果表明：油墨对丝网印刷的效果影响最为显著，紫外线光固油墨黏度适中，同时在特定光线光照条件下油墨固化快，文字平滑度比电子束辐射固化油墨好，不易蹭脏，印品相对完整，清晰，是最佳的丝网印刷油墨，但成本较高；5~10 cm/s的印刷速率变化对试验结果的影响较小。 |

| Aiming at the limitations of present molded pulp products color monotonous, surface structure complicated,and the shortcomings of poor products appearance, low added value, not be applied to the high end product packaging, put forward molded pulp packaging products surface printing solutions by the screen printing method. The design of molded pulp packaging products surface printing solutions to pulp products for printing, screen printing with water based ink, UV curing inks, electron beam curing inks for surface printing ink experiment, through different printing speed, screen printing pressure, spacing, and assess the effect of pulp molding surface printing test packaging products, in order to determine the most suitable process parameters. The experimental results show that the effect of printing ink on screen printing is the most significant. UV curing ink viscosity is moderate, and in particular the light illumination ink curing fast text smoothness than the electron beam radiation curable ink is good, not easy to get dirty, printing is relatively complete, clear, is the best screen printing ink, but the cost is high, the effect of 5~10 cm/s printing speed change on the test result is small. |
