通过设定标准的出版条件和印刷条件，测量并分析了印刷样张的实地密度、网点扩大、相对反差等印刷质量控制参数，基于这些参数建立了CTP印版输出补偿曲线，确定了最佳的印刷参数，获得了理想的印刷效果。

By setting the standard of printing and platemaking conditions, the printing quality control parameters of printing sample such as solid density, dot gain and relative contrast were measured and analyzed. The CTP compensation curves were plotted based on these parameters. The optimal printing parameters were determined and the ideal printing effect was obtained.
