 摘要：人们对印刷质量的要求越来越高,印刷质量控制的数据化、规范化和标准化成为印刷业界广大生产者、经营者和消费者所普遍关注握，密度的大小直接反映了反射光量多少，因而从数值上就可直接判断颜色的深浅、油墨的厚薄，方法简单、易掌握，适用于对印刷生产条件和过程的控制，尤其对印刷工艺的宏观控制较为理想。
 本课题研究密度对印刷质量的影响，确定实验方案，在使用分光密度计测量过程，测量印刷密度、网点面积、叠印率，对这些数据进行了拟合，分析，从该数据可以直接判断颜色的深浅、油墨厚度等。指导生产管理人员正确加网、确定油墨、曝光量、水墨平衡等，印刷网点增大是不能被消除的，但我们应该做到尽量减小和规范在一个合理的范围内，同时采取措施来补偿网点增大造成的不良影响，进而控制印刷的质量，为实际印刷中提高印刷品质量提供了一定的依据。在新行业发展框架里为技术能力提高和生产能力的增加系统寻找最新的解决问题的方法，也是为通过精深的理论探讨和研究来节省试验时间和成本。实现印刷工业生产的高度自动化，提高经济效益。

Abstract: people are printing more and more high quality requirements, quality control of printing data, standardization and standardization of the printing industry to become large producers, operators and Consumers are generally concerned about the grip, the size of the density directly reflects the amount of light reflected how much, and thus can directly determine from the numerical depth of color, ink thickness, simple and easy to handle, suitable for printing production conditions and process control In particular, the printing process of the macro-control is better.
 Therefore, this issue of the impact of density on the printing quality, experimental program to determine, in the measuring process using the spectral density, measured print density, dot area, trapping rate, the data were fitted to analyze, to judge from the color of the data can be directly the depth of ink thickness. Guide production management right screening, to determine ink, exposure, balance, ink, printing dot gain can not be eliminated, but we should do to minimize and regulate in a reasonable range, while taking measures to compensate the adverse impact of increasing network and then control the printing quality of the actual printing to improve print quality and provide some basis. In the new industry framework for the technological capabilities to enhance and increase system capacity looking for the latest ways to solve the problem, but also for theoretical study through intensive testing and research to save time and cost. To achieve highly automated production printing industry, to enhance economic efficiency
 Keywords： Density meter; trapping rate; dot
