Polynomial regression fitting analysis on influencing factors for printing ink transfer rate

According to ink transfer law, the text analyses the developing trend on influencing factors of ink transfer rate including printing speed, printing pressure and printing material. Through large amounts of experiments, three types of influencing datas have been obtained. Based on polynomial regression method, experimental datas have been fit with Matlab software and the fitting curves of the three influencing laws on ink transfer rate can be gotten. By analyzing the tendency of the influence of three factors quantitatively, the results show surface smoothness of printing material has the least influence on ink transfer rate in three factors including printing speed, printing pressure and printing material, and the printing speed and printing pressure have similar influence on ink transfer rate roughly. The experimental research has active significance to take corresponding measures to control processing parameter, keep printing process and ensure stabitity of printing mass.
