1 Scope

GB/T 13217.2-2024 is the Chinese national standard on test method for gloss of ink, in the field of paint and colour industries. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 15 March 2024 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 October 2024. Classification: ICS 87.080, CCS Y44. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This document describes the method for testing the gloss of inks. This document is applicable to the gloss test of paste inks and liquid inks, but not to the gloss test of inks containing metallic pigments.

3 Terms and definitions

There are no terms or definitions that require definition in this document.

4 Principle

The gloss of ink is measured by gloss meter. Under the irradiation of specified light source, the ratio of the reflected light of printed sample to that of standard surface is expressed as To express the gloss of the sample ink (measured with the reflected light of the standard surface as 100%).

5.Inspection conditions The test should be carried out under the conditions of temperature (23±2)°C and relative humidity (65±5)%.

6 Glossmeter Calibration

6.1 Preparation of instruments Press the power switch of the instrument and put the "measure, hold" button in the "measure" position to preheat the instrument for 3 minutes. The instrument should be calibrated frequently at the beginning of the cycle and during the measurement process (generally, the instrument needs to be recalibrated after 10 minutes of continuous measurement) to ensure Ensure that the instrument sensitivity is within the specified range; or start and prepare according to the instrument instructions.
