GB/T 38153.3-2019Graphic technology -- Laboratory preparation of test prints -- Part 3: Screen printing inks (English PDF)

Foreword

GB/T 38153 "Laboratory preparation of printing technology test prints" is divided into three parts.

---Part 1. Paste ink;

--- Part 2. liquid ink;

--- Part 3. Screen ink.

This part is the third part of GB/T 38153.

This part is drafted in accordance with the rules given in GB/T 1.1-2009.

This section uses the translation method equivalent to the ISO 2834-3.2008 "Printing Technology Test Preparation for Laboratory Preparation Part 3. Silk

Net ink.

1 Scope

This part of GB/T 38153 specifies the preparation method of the test print of the screen printing ink. This test print is mainly used for optics

Testing, such as the colorimetric method, transparency and optical reflection density described in ISO 2846-4, can also be used to test the printing ink and/or substrate light

Ze, light and chemical, physical and mechanical properties.
