Ink Drying Tester
The Ink Drying Tester is designed and manufactured according to the Chinese Light Industry Standard QB562 “Methods for Testing Ink Drying”. It provides a reliable method to determine the drying time of inks. The drying time is defined as the time required for an ink sample, with a specified amount of siccative added, to prevent adhesion of tracing paper under a defined pressure, expressed in hours. Testing is conducted by comparing the standard reference sample with the test sample. The instrument uses microcontroller control and LCD display for test parameters.
Application
(1) Determination of ink drying time for gravure, flexographic, or offset inks
(2) Quality control of ink formulations in R&D laboratories
(3) Comparison of standard ink vs. modified ink drying performance
(4) Laboratory evaluation of printing substrates and coatings

Test Procedures
Fix the standard reference sample, test ink sample, and tracing paper onto the drum using adhesive tape.
Set the drum rotation speed and start the rotation.
Apply the pressure roller along the drum’s axis at a constant proportion.
Count the number of adhesion marks on the tracing paper.
Calculate the drying time of the test ink based on the observed adhesion marks.
Compare with standard sample to evaluate performance.
Maintenance Information
(1) Clean the drum, pressure roller, and tracing paper holder after each test to prevent residue buildup.
(2) Check for smooth rotation and proper alignment of the pressure roller regularly.
(3) Avoid exposure to moisture or corrosive substances.
(4) Inspect the electronic control system and LCD display periodically for faults.
(5) Calibrate speed and pressure rollers annually to ensure accurate results.
