Description

Technical Field

[0001] The utility model belongs to the technical field of chemical measurement, in particular to an integrated device for multi-parameter real-time measurement of different inks on paper substrates. Background Art

[0002] With the continuous progress of printing technology, the requirements for the quality of printed products are increasing day by day. From high-resolution images to fast-drying inks and then to environmentally friendly and recyclable paper materials, each item poses higher challenges to the interaction between inks and paper.

[0003] The contact angle, as a key indicator for measuring the wettability of inks and paper, is directly related to the spreading speed, penetration depth, and dried morphology of inks. The contact angle of an ink on paper refers to the angle formed when the liquid ink contacts the paper surface, which has an important impact on the behavior and performance of the ink on paper. By detecting the ink contact angle, the ink formulation and paper treatment technology can be optimized to improve printing quality, ink drying speed, and paper surface characteristics, thereby enhancing the quality and readability of printed products.

[0004] The spreading coefficient refers to the ability of an ink to cover paper. When the ink contacts the paper surface, the ink will form a thin film on the paper surface. The spreading coefficient describes the covering ability of this liquid film, that is, the degree to which the ink covers the paper surface. Inks with a high spreading coefficient can cover the paper surface more fully, reducing problems such as blank spaces and uneven penetration. In addition, optimizing the spreading coefficient also helps to improve the drying speed of the ink, reduce the waiting time during the printing process, and increase production efficiency.

[0005] Currently, there are already surface tension meters to measure the surface tension of paper and contact angle meters to measure the contact angle of inks on paper. However, there is no device that can simultaneously measure the spreading coefficient of inks, nor is there a device that can measure the contact angles of multiple inks on different papers at the same time. Therefore, it is necessary to develop a device that can simultaneously detect the contact angles and spreading coefficients of multiple inks on different paper surfaces, which is not only an urgent need for the technological upgrade of the printing industry but also an important part in promoting printing quality.
