Paramrter Optimization Of Plastic Gravure Hot Air Drying

As a kind of commonly used plastic printing technology, it has particular printing characteristic and is widely used at home and abroad. It is important to chose the correct drying parameter in gravure printing techniques. It is not only the key to the quality of printing image but also the assurance which make remaining amount of solvent accord with the government criterion and the least energy consumption.There are too many factors influencing drying and the printing ink drying is a dynamic course of, which is very difficult to test. Up till now, the drying of the gravure printing machine has not a unified theory model. In printing process, most operator confirm drying parameters by experience, thus with much blindness, one side it influence printing quality, the other side reduced production efficiency and caused the energy waste. So it is essential to find a model that is suitable for fixing drying parameter of gravure printing.The thesis is based on plastic gravure printing hot air drying theory, combined with gravure hot air drying device to research in characteristic of ink on press products in drying process and influence factors. Analyze the factors to influence plastic gravure printing drying such as hot air temperature, velocity and initial content of solvent through gas chromatography. Make multinomial regression analysis experiment by MATLAB, establish mathematics model on the parameter of press products convention drying and remaining amount of solvent. Optimize the parameters to minimize the energy on condition that printing quality and remaining solvent are eligible. Instruct the practice such as drying device and drying press with the optima drying parameter.
