Abstract: Printing pressure is the basis for printing ink’s transferring into the surface of bear and print things It is not only the fundamental assurance of realizing the printing process, but also the critical factor of printing quality. The purpose of this paper is to study the pressure on the print quality by printing the impact of the printing pressure by experimental transfer of ink to be printed pressure to the printing quality.
Based on printability meter simulation printing process, experiments are designed. the same printing speed and the printing ink, under the different printing pressure carries on the experiment to the type paper, through the adjustment printability meter printing pressure, the survey printing ink shifts from the printing plate to accepts for printing on the material the ink quantity, the test printing ink transfer rate. Has carried on the fitting to these data, then discovers the printing pressure and the printing ink transfer rate functional equation, sought the best printing pressure for actual printing in to provide certain basis. To produces ink volume, the printing speed, the printing pressure and so on the adjustment, has certain guiding sense. Seeks newly in the new profession development frame for the technical ability enhancement and the productivity increase system solves the question method; Also is for saves the experimental time and the cost through the profound theory discussion and the research. The realization printing industrial production automates highly, enhances the economic efficiency.
