Specular gloss is a very important appearance parameter of printed matter. High gloss may be preferred for some purposes such as magazine covers, packaging and advertising, while lower gloss is preferred for minimizing glare, for example, in reading text. This method provides a means of determining gloss of prints produced in the laboratory, or to monitor print gloss on a production printing press.1.1 This test method covers the procedure for determining the specular gloss of printed matter. 1.2 This test is applicable to prints on any flat substrate including paper, paperboard, metallic foil and plastic produced by any printing process, either in the laboratory or on a production printing press. 1.3 This standard does not purport to address all of the safety concerns, is any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.

4.1 This test method may be used to compare the gloss of porcelain enamel, ceramic, and other finishes or to provide a comparison of their resistance to attack from acid, alkali, or other environmental factors by measurement of gloss loss.1.1 This test method covers the determination of the specular gloss of porcelain enameled specimens, but may be applicable to other specimens having similar reflection characteristics. This test method may be used to compare the gloss of porcelain enameled specimens or to provide an index of acid or abrasion resistance by measurement of gloss loss.NOTE 1: Specular gloss is one of several related appearance attributes that produce the sensation of glossiness. For this reason, specular gloss measurements may not always correlate well with visual rankings of glossiness.NOTE 2: Improved correlations with visual judgments can sometimes be achieved by the use of instruments with different geometries than those specified herein. Refer to Test Method D523 for 20, 60, and 85-deg geometries. Values generally cannot be predicated for one geometry from measurements made with another.1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.3 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.

1.1 This test method is primarily intended to measure the gloss of waxed papers. Note 1--For determining the gloss of book paper reference should be made to Test Method D1223. For very high gloss paper see Wink et al (1). 1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

5.1 Gloss measurements are used to qualify a raw material or finished product.5.2 Sample preparation will effect the outcome of gloss readings. This practice will eliminate second surface reflection, and allow a more accurate gloss reading of the substrate.5.3 Materials which require this preparation include the following: clear or translucent substrates, colored transparent substrates, and areas printed with clear, translucent, or transparent colored coatings.1.1 This practice covers the method of sample preparation, prior to taking gloss measurements on a membrane switch overlay.1.2 Typical applications include window display areas on a graphic overlay, and surface texture.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

1.1 This test method is intended primarily to measure the gloss retention of waxed specimens exhibiting relatively good gloss. 1.2 The values stated in acceptable metric units are to be regarded as the standard. The values in parentheses are for information only. 1.3 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
