本文件规定了用于改变图像的透镜打印的图像质量的测量方法和规范。本文档不包括用于3D图像的透镜打印。注:3D图像的透镜状打印可以通过相同类型的程序进行测量。然而，它需要更多的信息来评估3D性能，例如测量距离的依赖性。本文件具体描述了串扰、视角范围、与设计视角的角度偏差以及透镜打印图像打印区域内图像均匀性的测量方法。这些对于改变图像的透镜打印的图像质量至关重要。本文件适用于由印刷技术生产的透镜印刷品，包括冲击式和非冲击式印刷。前者的例子有胶印、凹印和柔性版印刷，后者的例子有卤化银、喷墨、染料扩散热转移和电子照相。还使用了多个激光图像（MLI）和可变激光图像（CLI）过程，即使用激光以不同角度写入透镜屏幕以创建多个图像。

This document specifies the measurement methods and specification of image quality of lenticular prints that are used for changing images. This document does not cover lenticular prints that are used for 3D images.NOTE Lenticular prints for 3D images can be measured with the same types of procedures. However, it needs more information, such as the dependence of the measurement distance, to evaluate the 3D performance.This document specifically describes measurement methods for cross-talk, viewing angle range, angular misalignment from the designed viewing angle and the uniformity of the image within the printing area of the lenticular print images. These are critical for the image quality of lenticular prints for changing images.This document is applicable to lenticular prints produced by printing technologies that include impact and non-impact printing. Examples of the former are off-set, gravure and flexography, while the examples of the latter are silver halide, inkjet, dye diffusion thermal transfer and electrophotography. The multiple laser images (MLI) and changeable laser images (CLI) process of using a laser to write through a lenticular screen at different angles to create multiple images is also used.
