办公设备 彩色印刷品的印刷质量测量方法 第2部分：套准和放大精度

[中文适用范围]： 本文件规定了测试方法以及测试图表，用于测量通常用于办公环境的双面彩色打印的几何属性和变化。本文件适用于由多张纸组成的双面打印，这些纸在基材的两个表面上都打印有彩色图像。“页面内变化”和“纸张间变化”也适用于由多张纸组成的单面打印集，这些纸在基材的一个表面上打印有彩色图像，而另一个表面上没有图像。使用除青色、品红、黄色和黑色以外的四种原色的打印不在本文件的范围内。包括使用多功能或单功能打印机形成的数字打印。在评估双面打印集时，能够自动在基材的两面打印图像的双面打印机是适用的，而需要在正面和背面打印之间手动安排基材以形成双面打印的单面打印机不在本文件的范围内。最大适用基材尺寸为 A4 或更大的打印机适合进行测量。所包含的几何属性包括印刷集的配准和放大。微观几何密度变化（如颗粒度、斑点和线条粗糙度）不在本文档的讨论范围内。考虑的变化来源包括页面中的位置、纸张中的打印面、印刷集中纸张的打印顺序以及原色之间的变化。 [外文原描述]： This document specifies test methods as well as test charts to measure the geometric property attributes and those variations in duplex colour prints typically used in office environment. This document is applicable to duplex prints comprising several sheets which are printed colour images on both surfaces of a substrate. “Within-page variation” and “sheet-to-sheet variation” are also applicable for a simplex print set comprising several sheets, which are printed colour images on one surface of a substrate and no image on the other surface. Prints with four primary colourants other than cyan, magenta, yellow and black are outside the scope of this document. Included are digital prints formed by using a multifunction or single function printer. When a duplex print set is evaluated, duplex printers which are capable to print images on both sides of substrate automatically are applicable, while simplex printers which require a manual arrangement of substrates between the front side and back side printing to form duplex prints are out of scope of this document. The printers of the maximum applicable substrate size of A4 or larger are suitable for the measurements. The geometric property attributes included are registration and magnification of a print set. Microscopic geometrical density variations, such as graininess, mottle and line raggedness, are outside the scope of this document. The sources of variations considered are locations in a page, print side in a sheet, print order of sheets in a print set, and variations among primary colours.
