| 中文摘要: |
| 目的 为提高喷墨数字印刷质量。方法 用普通相机和共聚焦激光显微镜对卷筒纸喷墨数字印刷质量缺陷进行记录和对比。结果 常见的数字喷墨印刷质量缺陷主要有色彩还原性差、印品单张不平（“荷叶边”）、图文墨迹边缘“毛刺”、印刷墨色不实、背粘、套印不准、脏污、内页增大和白条等。结论 质量缺陷产生的原因是喷墨数字印刷缺乏压印过程，使用低粘度、低颜料含量的水性油墨会导致干燥速度慢和纸张吸墨性差，因此在纸张表面构筑可以精确调控单个墨滴纵向渗吸和横向铺展相对量的功能涂层是提高喷墨数字印刷质量的有效对策。 |

| The work aims to improve printing quality of digital ink jet printing. Common camera and confocal laser microscope were used to record and compare the quality defects of the web digital ink jet printing. The main quality defects of common digital ink jet printing are as follows: worse color restoration, uneven printing leaflets (“lotus leaf edges”), graphic edge “burr”, printing ink color not as thick and heavy as where needed, back adhesive, misregister in overprinting, enlarged inside page and white line. The reason for quality defects is lack of pressure in digital ink jet printing. In addition, the water-based ink with low levels of viscosity and pigment will result in exceedingly slow rate of drying and poor ink absorption. Therefore, the construction of functional coatings on the paper surface can accurately control the relative amount of the longitudinal imbibition and lateral spreading of a single drop, which is an effective countermeasure to improve the quality of digital ink jet printing. |
