Color copy of the image uniformity test methods1 ScopeThis standard specifies the color copy of the image at 20 °, 60 ° and 75 ° under the geometric conditions of the uniformity of the test method. This standard applies to electrostatic color imaging of the copy. Color print reference to use.2 Normative referencesThe following documents for the application of this document is essential. For dated references, only the dated version applies to this article Pieces. For undated references, the latest edition (including all amendments) applies to this document. Paper and board - Determination of specular gloss GB/T 8941-2013 GB/T 9754-2007 Paints and varnishes - Determination of specular gloss at 20 °, 60 ° and 85 ° for metallic paint-free paint films3 Definition of termsGB/T 8941-2013 defined and the following terms and definitions apply to this document. For ease of use, the following list is repeated GB/T 8941-2013 some of the terms and definitions. 3.1 Gloss gloss The direction of the surface of the object to select the nature of the reflection, which determines the nature of the surface can be seen in the strong reflection of light or object mirror Like the degree. [GB/T 8941-2013, Definition 3.1] Note 1. The gloss is expressed as 100 times the ratio of the luminous flux reflected by the sample surface to the specified aperture and the luminous flux reflected by the standard mirror under the same conditions. Note 2. An image with a high specular reflection on the front surface is considered to have a high gloss, whereas an anterior surface is more specular on the image being considered as low gloss degree. The gloss value will vary depending on the measurement method (eg, glossmeter measurement angle and sampling area size) and the level of gloss in the region of interest And different. Note 3. GB/T 8941-2013 provides that the refractive index of 1.567 polished black glass as a gloss benchmark, assuming that the plane in the ideal polishing State, from the plane of the natural beam of the mirror reflection, the definition of the gloss value of 100 gloss units. Note 4. Definition of GB/T 9754-2007 3.1 The specular gloss is "To determine the specular gloss scale, a polished black glass with a refractive index of 1.567 The specular gloss value of 100 given the geometrical conditions of 20 °, 60 ° and 85 °. "4 principleWith the gloss meter determination and the normal line of the copy at an angle (20 °, 60 ° and 75 °) incident on the printed surface, and from the printed surface and the normal The light reflected to the specified aperture at the corresponding angles (20 °, 60 ° and 75 °) is displayed on the gloss meter.5 instruments and devices5.1 optical system 20 °, 75 ° gloss meter should meet the technical requirements of GB/T 8941-2013, 60 ° gloss meter should be consistent with GB/T 9754- ...... |
