SN-03, SN-06 (with heating) ink burst tester

The ink bursting of trademark paper is a systematic problem, which is essentially caused by the insufficient flexibility and adhesion strength of the ink layer to match the deformation of the substrate under external stress, resulting in the phenomenon of linear cracking as the main feature of the ink layer. Usually occurs during die-cutting indentation, folding molding, and subsequent storage and transportation processes. The reasons may come from the ink itself, printing materials, printing process, storage conditions, color box design, and other aspects.

1、 Instrument features

   (1)The roller axis spacing, pressure, speed, and temperature can be adjusted (specific models).

   (2)Semi closed protection of the injection port enhances operational safety.

2、 Instrument principle

The ink burst tester simulates the printing process by applying a certain pressure and rolling speed to the sample, heating it to a set temperature (optional), in order to scientifically evaluate the phenomenon of ink burst and identify the cause of ink burst.

3、 Instrument application

Application:

Scientifically evaluate the phenomenon of ink bursting after folding trademark paper.

The significance of detecting ink bursting:

   (1)Ink selection: Choose specialized inks with high flexibility and toughness (such as "anti folding ink"), and strictly test their adhesion and flexibility.

  (2)Process optimization: Fine control of drying/curing energy; Optimize die-cutting pressure to make the indentation "clear without bursting"; control workshop temperature and humidity.

  (3)Material matching: Select the appropriate paper according to the folding requirements.

  (4)Design avoidance: Consider the risk of explosion during the design phase.

  (5)Forward detection: Quantitative testing of semi-finished products is carried out after die-cutting and before machine operation to warn of risks in advance.
