4. Discuss nanocomposites from the perspective of printability
In the field of printing, printability is a comprehensive discussion. Even those who have been engaged in the printing industry for many years are not easy to grasp the whole essence. "Printing suitability" refers to the problem of adaptability caused by the matching of all printing materials, and even includes various factors such as environment and personnel. In printing, high-quality printing machinery does not mean that the printability is necessarily good.
The same ink is printed on different paper, and the effect may be different. Or, printing on two different printing machines A and B with the same ink. As a result, the printing machine A works well, but the printing machine B has a problem of ink accumulation; if another brand is used on the printing machine B Ink printing, but no ink accumulation. The above examples are about the suitability of printing. Therefore, the printing industry may be more concerned about the printability of the machine material than the grade.
Similarly, the concept of printability also applies to nanoprinting materials. The R & D Center is currently focusing on the research on the printing suitability of nano-ink and nano-paper. The research on the printing suitability of nano-ink and nano-paper will be carried out by the testing methods provided by the center for many years, and its equipment includes hardware and software.

Nano ink printing suitability research includes: chromaticity and concentration test, emulsification rate test, viscosity test, anti-cleavage test, light resistance test, chemical resistance test, etc. of the ink color samples, in which the chromaticity and concentration test is to test the ink Color performance; emulsification test is used to analyze the emulsification of lithographic ink; viscosity test and anti-splitting test can speculate the situation of the ink on the printing machine. Normal phenomenon; lightfastness and chemical resistance tests are used to test the degree of resistance of printed finished products to chemicals.
