文档介绍：several group number, then with b ± a, =c,c is is methyl b two vertical box between of accurate size. Per-2~3 measuremen度量、测定也就定义了参考的印刷条件。
在这一张投影中会给出定义参考印刷机A-E的五个步骤。首先要对参考印刷机进行设置，设置的过程中要根据ISO12647所定义的参数来进行，这个参数包括四色油墨的LAB的色调值曲线，这些都要完成规定，在设置过程中要特别小心操作印刷机，在正常的状态下运转，不要出现机械的故障。
第二步骤B要采用合适的油墨，采用低于ISO2846所规定的标准油墨进行印刷。
第三步骤C要准备好由ISO12642所制订的特性化印刷表测定出来。在印刷测试表时，要注意保证原色油墨的实地和基调值曲线，尽可能满足标准的规定要求。
第四步骤D中选择一些在实地和和基调值曲线上能够满足标准的样张，并且对他进行测试，这些样张中会有一些小的偏差，数据要进行处理，在需要的情况下，还需要做一些平滑化的处理。

Per-2~3 measurement, such as proceeds of c values are equal and equal to the design value, then the vertical installation accurate.
