Test method for colour of plastics gravure printing inksSubject content and scope of application
This standard specifies the test method for the colour of gravure printing inks for plastics. This standard is applicable to the test of the colour of gravure printing inks for plastics. Principle
GB/T 13217. 1-- 91
Compare the ink sample to be tested with the standard ink sample by the parallel scraping method to check whether the ink colour meets the quality standard of the standard ink sample. 3 Materials
3.1 Low-density polyethylene film: The surface wetting tension after electric spark treatment is 38×10-540×10-5N/cm (38~40dyn/cm), and the thickness is 0.05±0.01 mm.
3.2 Rubber pad: 240mm×140mm×4mm. 3.3 Scrubbing solvent: ethanol or gasoline.
3.4Coated paper: 150g/m2.
4Instruments
4.1Glass rod: Φ7mm, length 250mm.
4.2Wire rod: Copper rod body ±9±0.05mm, length 170mm, stainless steel wire winding part length 100±0.50mm, steel wire g0.12mm, closely wound, neatly arranged without gaps.
5Testing conditions
5.1The test should be carried out at a temperature of 25±1℃ and a humidity of 65%±5%. 5.2When inspecting the color, it should be carried out under the D65 standard lighting body with an incident angle of 45°±5°. 6 Inspection steps
6.1 Use a glass rod to adjust the standard sample and the test sample respectively, then take a small amount of the standard sample and drop it on the upper left of the low-density polyethylene film with a rubber pad and fixed upper end, and then take a small amount of the test sample and drop it on the upper right. The two should be adjacent but not connected. 6.2 Use a wire rod to forcefully scrape a thin layer of ink on the low-density polyethylene film from top to bottom. As shown in the figure: Approved by the State Bureau of Technical Supervision on September 14, 1991 and implemented on August 1, 1992
