3 Principle
Quantitatively dilute the sample and standard sample, compare the concentration of the diluted ink, and express it in percentage. 4 Tools and Materials
4.1 Scrape Sample Paper: 80g/m offset printing paper (conform to Grade A in QB3/T1012[991) Specification 210mm×70mm, with a 20ml wide black solid horizontal line 130m below the top. 4.2 Series of White Ink Relative Black
4.3 Instruments
4.4 Weighing Bottle: Capacity 50 ml.
4.5 Analytical balance: accuracy 0.001g
4.6 Attached sheet
4.7 Cleaning solvent; different system liquid inks use special solvents of the same system. 5 Test conditions
5.1 The test should be carried out at a temperature of (23+2)℃: 5.2 The test should be carried out under D65 standard lighting 5 Test steps
6.1 Use a weighing bottle on the analytical balance to weigh 1g of sample liquid and 10g of white ink. Use the same method and the same proportion to weigh the standard sample ink and self-ink, and mix them thoroughly with an ink mixing bottle.
6.2 Dilute the ink, take a small amount of the standard sample, and place it on the upper left of the scraping paper; take a small amount of the sample, and place it on the upper right of the scraping paper. The two are adjacent but not connected. Use a scraper to scrape from top to bottom until the ink is 80 mm~100 mm long. Reduce the inner angle of the scraper to make the ink a thicker layer, as shown in Figure 1.

General color dilution diagram
6.3 Observe whether the color and color of the sample and the standard sample are consistent. If not, change the amount of sample, and the diluted sample and the standard sample are consistent. Then calculate according to formula (1) to obtain the difference in color between the sample and the standard sample. 6.4 Scrape the sample lip and take the color reflected by the observation within 305 as the test result. The tinting power is calculated according to formula (1): S
tinting power percentage (standard sample is {00%); D
amount of white ink used to dilute the sample: the unit is gram (g); the amount of white ink used to dilute the standard sample, the unit is gram (g), × 100
Note: When testing the white tinting power, the standard sample and the sample are used to replace the white ink used above, but the white ink is replaced by 10·Xi as 1. The operation method is the same as above, and the calculation formula is the same as formula (1), but C is the test amount of the sample, and D is the white ink used for the standard sample.
