1.目的、范围和应用1。1目的。本标准旨在确定光学字符识别（OCR）系统中使用的纸张的要求和测试程序。1.2范围。本标准包含光学字符识别读取器用纸张的基本定义、测量要求、规范和建议。介绍了OCR介质的两种纸张参数。这些是:（1）用于OCR的纸张的光学特性；（2） 用于OCR的纸张的物理性质。 此外，OCR纸张根据允许的污垢和荧光含量分为三类（I、II和III型）。1.3应用。由于OCR应用的性质差异很大，本标准可能不包括成功的OCR系统所需的所有必要或谨慎的规范或考虑因素。本标准中的值是在合理获得的基础上选择的。尽管每个参数都是独立指定的，但如果同时接近一个或多个参数的极限，读卡器性能可能会下降。 如果涉及新的OCR设备或新纸张，建议用户、供应商和制造商之间进行协商。

1.Purpose, Scope and Application1.1Purpose. The purpose of this standard is to establish the requirements and test procedures for paper to be used in Optical Character Recognition (OCR) Systems.1.2Scope. This standard contains basic definitions, measurement requirements, specifications, and recommendations for papers used with optical character recognition readers.Two types of parameters of paper for OCR media are covered. These are: (1) The optical properties of paper for OCR usage; (2) The physical properties of paper for OCR usage.In addition, OCR papers are classified into three categories (Types I, II, and III) according to allowable dirt and fluorescent content.1.3Application. Because of the widely divergent nature of OCR applications, this standard may not include all of the necessary or prudent specifications or considerations for a successful OCR system. The values in this standard are chosen on the basis that they are reasonably obtainable. Although each parameter is independently specified, a deterioration in reader performance may occur if the limits of one or more parameters are approached simultaneously. Where new OCR equipment or a new paper is involved, consultation between users, suppliers, and manufacturers is recommended.
