摘要
以素面镭射纸为例,通过实验,阐述了结合相对反差和色彩反差来确定印刷最佳实地密度的方法。实验研究表明：随着印刷压力的增大,实地密度值不断增大,相对反差和色彩反差值经历了一个先增大后减小的过程;品红墨的最佳实地密度范围是1.247-1.268,青墨的最佳实地密度范围是1.532-1.559;对于具体最佳实地密度的确定,应根据印刷条件以及印刷产品种类等来决定应优先考虑哪种反差,从而确定该产品印刷的最佳实地密度。
The method was illustrated by experiment on plain laser paper to combine relative contrast and color contrast to obtain optimum solid density of printing.It was shown by experiment results that the solid density value was incessantly increasing with the increasing of printing pressure,and relative contrast value and color contrast value had a process of firstly increasing and then decreasing.The optimum solid density scope of magenta ink and cyan ink ranged from 1.247 to 1.268 and from 1.532 to 1.559 respectively.It should be in accordance with with printing conditions and the type of print product to determine which kind of contrast should be given priority to,so as to ascertain the optimum solid density of that printing product.
