1.1 本规程涵盖了使用手动平板实验室校样压力机制备糊状油墨印刷品的程序。最初的方法是由国家油墨研究所开发的。 2. 1.2 本规程适用于在平坦基材（如纸或金属）上通过干式胶印工艺（也称为凸版）制备单色固体区域印刷品。它可以很容易地适应直接活版印刷。 3. 注1: 本规程中描述的打样机也可根据规程与印刷量规一起使用 D6846 . 1.3 本规程主要适用于通过氧化或渗透干燥的平版印刷和活版印刷油墨。通过添加适当的干燥或固化设备，它也适用于其他系统，如热固化或能量固化。 1.4 本规程中的说明旨在尽量减少手动操作中固有的打印内和操作员之间的可变性。 1.5 本规程不测量印刷品上的实际膜厚，但通过视觉或仪器比较反射密度来评估膜厚等效性。 1.6 以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 1.7 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 具体预防措施见第节 7. . 1.8 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 油墨的实验室打样对于建立印刷外观和性能特性的可复制预测是必要的，其中大多数对油墨膜厚度高度敏感。本规程中描述的设备已广泛用于常规控制打样，因为它提供了一种经济的方法，可以以与生产压力机上获得的薄膜厚度相当的厚度生产出相当大的印刷品。 4.2 这种做法不会复制高速印刷机的动态，但是，它有助于质量控制，并有助于生产商和用户之间的规范验收，其中有一个商定的反射密度或标准参考打印规范。

1.1 This practice covers the procedure for preparing prints of paste inks using a hand operated flat-bed laboratory proof press. The initial method was developed by the National Printing Ink Research Institute. 2 1.2 This practice is applicable to the preparation of single-color solid-area prints by the dry offset process (also known as Letterset) on a flat substrate such as paper or metal. It can readily be adapted to print by direct letterpress. 3 Note 1: The proofing press described in this practice can also be used with printing gages in accordance with Practice D6846 . 1.3 This practice is applicable primarily to lithographic and letterpress inks that dry by oxidation or penetration. With the addition of appropriate drying or curing equipment, it is also applicable to other systems such as heat-set or energy-curable. 1.4 The instructions in this practice are intended to minimize the within-print and among-operator variability inherent in hand operations. 1.5 This practice does not measure the actual film thickness on the print, but evaluates film thickness equivalence by visual or instrumental comparisons of reflection density. 1.6 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the users of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific precautions are given in Section 7 . 1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 4.1 Laboratory proofing of ink is necessary to establish a reproducible prediction of print appearance and performance properties, most of which are highly sensitive to ink film thickness. The apparatus described in this practice has found wide use for routine control proofing because it provides an economical method for producing reasonably large prints at film thicknesses comparable to those obtained on production presses. 4.2 This practice does not duplicate the dynamics of a high speed press, nevertheless, it is useful for quality control and for specification acceptance between the producer and the user where there is an agreed upon specification for reflection density or standard reference print.
