4 Test method
4.1 Appearance inspection
4.1.1 Inspection principle
Mix the ink on the glass plate and inspect the appearance of the ink. 4.1.2 Tools and materials
a) Mixing knife;
b) Glass plate.
4.1.3 Inspection steps
a) Use the mixing knife to take 20g of the sample and mix it on the glass plate; b) Check whether there are any foreign matter, lumps or other abnormalities. 4.1.4 Test results
No foreign matter and no lumps are each grid.
4.2 Color test
4.2.1 Test principle
Compare the sample ink and the standard ink by scraping them side by side. Under the standard light source, use the gray sample card for evaluating color change (see GB250) to evaluate the surface color, background color and color level of the sample ink and the standard ink. 4.2.2 Tools and materials
a) Small steel scraper;
b) Small adjustment knife;
c) Scraping paper (80g~100g double-sided paper) 215mmx70mm, with a 20mm black horizontal line printed at 130mm; d) Glass paper:
e) P6s standard source:
F) Color sample card for evaluating color change (see item 250) 4.2.3 Test steps
a) Use a small amount of ink to take a small amount of the standard sample and the test sample, and mix them on the glass plate for 10 to 15 times respectively; b) Take about 0.5g of the prepared ink and place them separately, with the standard sample on the right and the test sample on the left, adjacent to each other but not connected:) Hold the scraper upright and scrape the ink from top to bottom evenly to two-thirds of the black horizontal line, and gradually flatten the scraper so that the angle between the scraper and the paper is less than 30% so that the ink can be scraped into a thicker ink layer on the paper and below the black horizontal line, and then stick glass paper; d) The scraped sample is transparent to light at an incident angle of 35° to 45°, which is called the background color. The ink layer above the black horizontal line of the scraped sample is called the surface color: the ink layer at the exciting horizontal line of the scraped sample is called transparency, and the thick ink layer below the black horizontal line of the sample is called ink color. 4.2.4 Inspection results
Evaluate the color change with a gray card (see GB250) within 5 minutes, and evaluate the color level under the standard light source (Dg). 4.3 Fineness is tested according to the method in Appendix A of QE/T2624 (UV oil adjustment is used to adjust the viscosity). 4.4 Viscosity is tested according to GB/T18723 (UV special cleaning liquid is used for cleaning). 4.5 Color strength is tested according to GB14624.2.
4.6 Drying test
4.6.1 Inspection principle
Use a colorimeter with 2 grids to draw the test, and after transfer, irradiate the printed material with ultraviolet light to solidify the required film. Use scratches and touch to judge the quality of ink drying.
4.6.2 Tools and materials
a) Printability tester, 2-grid rubber bite: 2
b) Ink adjustment door, steel scraper:
c) Lead-under paper:
Standard sample oil wing:
e) UV special cleaning liquid:
f) UV irradiator:
g) Same-shaped needle (see QB treatment 1149),
4.6. 3 Inspection steps
QB/T2826-2006
a) Take 0.125mL of the test sample and standard ink, and place them on the cleaned 2-grid rubber roller respectively. According to the ink spreading speed inspection method, carry out a color development.
b) The color development object passes through a UV irradiator to solidify the ink film. The irradiation conditions are: 80W1cm high-pressure mercury lamp, irradiation distance of 15.5cm, speed of 64m/min, and irradiator power of 2kW. 4.6.4 Judgment method
a) After UV irradiation, place the printed surface on a glass plate and use the tail of a paper clip (see QB/T1149) to scratch the edge of the printed material. Check the blank part of the printed material to see if there is a mark left. Judge the dryness of the ink. At the same time, touch the film with your fingers to judge the dryness of the ink film.
b) If the ink film is not completely dry, irradiate it again and judge until it is dry.
judge whether there is any difference between the sample and the standard sample during the drying process, and record the results. 4.7 The content of mobile elements shall be tested according to Appendix C of GB6675. 4.8 Inspection conditions
The inspection shall be carried out at a temperature of (25±1)T and a humidity of (65±5)%. 5 Inspection rules
