3 Principle
At the specified temperature, temperature and time, the solvent of the ink print is tumbled at a certain speed to make the ink film of different thickness change from liquid to solid, which is the initial flatness, expressed as 30 meters per meter. 4 Tools and Materials bZxz.net
4.1 Scraping paper: 80g/m offset printing paper (in accordance with QB/1012-1991A grade) specification 210mm×70mm, 130mm from the top, with a 2Gmm wide black solid horizontal line, 4.2 Cotton yarn.
4.3 Scrubbing solvent: Use the same series of special solvents for different system liquid inks. 4.4 Adjust the force.
4.5 Stopwatch.
4.6 Mercury thermometer: temperature range ℃～50℃+division is 0.1℃, 4.7 Meter ruler: minimum scale value is 1mm
4.8 Rubber roller: 932mm, length 100mm, width is 50 degrees. 4. 90 μm-~100 μm Scraper longitudinal instrument. 5 Test conditions
5.1 Test should be conducted under the conditions of temperature (23±2)℃ and humidity (65+5)%. 5.2 Avoid the air outlet during test.
6 Test steps
6.1 Use a scraper to take a certain amount of the scraped sample with a temperature of (23-2)℃ and drop it on the plate at 100m to fill the groove. 6.2 Hold the scraper with both hands and place the scraper vertically and horizontally at the end of the scraper (at the edge of the sample), then move the scraper downward at a high speed to fill the groove with ink, and start the timer.
6.3 Align one end of the sub-sample paper with the zero mark of the scraper, and flatten the scraping sample paper after 30s, push it from the lower end of the scraper to L with a rubber, and then peel off the scraping sample paper vertically. GB/F13217.5—2008

Test results
Starting from 0um, use a straight scale to measure the length not marked with ink, expressed in millimeters. 7.1
The test should be carried out in parallel and the measurement error should not exceed 311. The result should be taken as the arithmetic mean.
