本文件规定了用于改变图像的透镜状印刷品的图像质量的测量方法和规格。本文档不包括用于3D图像的透镜状打印。笔记？3D图像的透镜状打印可以用相同类型的程序来测量。然而，它需要更多的信息，如测量距离的依赖性，来评估3D性能。该文献具体描述了用于串扰、视角范围、与设计视角的角度未对准以及透镜状打印图像的打印区域内的图像均匀性的测量方法。这些对于用于改变图像的透镜状印刷品的图像质量是至关重要的。本文件适用于通过印刷技术生产的透镜状印刷品，包括冲击和非冲击冲击印刷。前者的例子是胶印、凹版和柔性版，而后者的例子是卤化银、喷墨、染料扩散热转印和电子照相。还使用多个激光图像(MLI)和可变激光图像(CLI)过程，其使用激光以不同角度写入透镜状屏幕以创建两个单色图像。

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 crosstalk, 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 two monochrome images is also used.
