This portion of the GB/T 14624.1-1993 main differences are as follows.
--- Text format prescribed GB/T 1.1-2000 been modified;
--- Standard name was changed to "offset printing ink color test methods";
--- Like paper made from scratch blueprint paper to 80g/m2 offset printing paper;
--- Ambient temperature index has been adjusted to cancel the humidity requirements;
--- Increased provision for standard sample and sample viscosity difference;
--- Added Appendix A (gray scale for assessing change using methods like cards).
This section of Appendix A normative appendix.
This part is proposed by the China National Light Industry Council.

GB 250 assessing change in color like the gray card
QB/T 1012 offset printing paper
Principle 3
The sample was scraped with a standard parallel samples in standard light gray contrast assessing change in color sample card, visual view of both the sample and standard color difference
Different degree.
4 Tools and Materials
4.1 palette knife.
4.2 blade.
4.3 glass.
4.4 Sample scratch paper. 80g/m2 offset printing paper, in line with QB/T 1012A type; Size 210mm × 70mm, 130mm at the top down
Printed on 20mm wide black bars indicate the ground.
Note. Black Gantt view for ink opacity.
4.5 cellophane.
4.6 Evaluation of color like the gray card. meet GB 250.
5 Test conditions
5.1 test should be carried out at a temperature of (23 ± 2) ℃ conditions.
5.2 View complexion and ink should be conducted under D65 standard light source incident angle of 45 ° ± 5 °.
5.3 View background light should be scraped like perspective.
Step 6 test
6.1 with a palette knife to take samples and standard samples, each about 5g, placed on a glass plate, respectively, mix thoroughly.
6.2 with a palette knife to take about 0.5g standard applied to scrape the top right kind of paper, and then take a sample of about 0.5g sample coated paper scraping the top left of the two should be adjacent
But not connected.
6.3 The blade is placed on top of the coated sample of the ink, so that the main part of the blade and the blade-like paper angle of 90 °. Forced to scrape the ink from top to bottom
Scrape into thin like paper, until the black bars indicate 1/2 at reduced force, so that the inside of the blade angle of approximately 25 ° angle, so that the ink on the paper painted relatively
Thick with the ink (Figure 1). Final scratch-like shape should be similar to Figure 1.
