Nanotechnology and Printing Industry (II)

IV. Discussing Nanocomposites from the Perspective of Printability

In the field of printing, print suitability is a topic of comprehensive discussion. Even those who have been in the printing industry for many years cannot easily grasp the essence of the whole. "Printability" refers to the adaptability problems caused by the matching of all printing materials, and even includes various factors such as environment and personnel. In printing, a high grade printing press does not mean that the printability is good.

The same ink is printed on different papers, and the effects may vary. Or, the same ink is used to print on the two different printing machines A and B. As a result, the A printing machine works well, and the B printing machine has a problem of ink accumulation failure; if another printing plate is used on the B printing machine Ink printing, but no ink accumulation. The above examples are related to printability. As a result, printers may be more concerned about the printability of machinery than the quality level.

Similarly, the concept of printability also applies to nanoprinting materials. The Institute of Printing Research is currently focusing on the printability studies of nano inks and nanopapers. The research on the printability of nano inks and nanopapers will be conducted with the testing methods provided by the Center for many years. The equipment includes hardware and software. For some hardware detection devices, please refer to Figure 1 to Figure 7.

Nano ink printing suitability research includes: ink color sample color and concentration test, emulsification rate test, viscosity test, splitting resistance test, light resistance test, anti-chemical test, etc., in which the color and concentration test is to test the ink Color performance; emulsification test is used to analyze the phenomenon of lithographic ink emulsification; from the viscosity test and splitting resistance test can be speculated that the ink on the printing press, the ink viscosity and splitting force is not within the normal range, it will produce a printing press does not work The normal phenomenon; light and chemical resistance tests are used to test the impact of finished products on chemical resistance.
