Printing pressure is the pressure between the plate cylinder and the impression cylinder. Its main function is to transfer the ink on the plate evenly to the substrate. Many problems in the printing process are due to improper pressure adjustment, such as ink is too large or too small. If the printing pressure is too heavy, on the one hand in the substrate easy to thicken the lines, network expansion, reduced graphics accuracy. Adhesive printing Shanghai In addition, the imprinting force will also make Waleng deformation, cardboard strength decreased. If the pressure is too light, then the substrate can not transfer the right amount of ink, poor reproduction graphics, lines prone to break, the field easy to produce imprinting fault, a direct impact on the printing results, the printing can not be serious normal .
Printing pressure to adjust the ink uniform and moderate, clear ink, tile surface no depression, formation is not deformed. Roller accuracy adjustment, the main concentricity and parallelism problems. Concentricity is mainly between the roller body and the bearing journal and between the roller concentricity, the two concentricity must be adjusted. Press normal operation, the vibration error can not exceed 0.01mm, otherwise there will be ink transfer and dot printing failure. Heavy is the idea to expand, ranging from the image dot printing is not clear or not printed. Gear accuracy is to ensure that the roller concentricity of the foundation, the transmission gear accuracy changes, there will be micro-vibration and other mechanical shortcomings, to bring certain difficulties network cable printing, the entire printing can not get an ideal pressure. Mechanical vibrations will also damage the anilox roll and plate, affecting service life and product quality. Parallelism mainly refers to the parallel between the two roller axis relative position.
Food Hygiene Inspection Laboratory
The environment of the food testing laboratory should be kept clean, dust-free, odorless, noiseless, and suitable for temperature and humidity. The decoration design should consider facilities such as air purification, ventilation, lighting, water and electricity to ensure that the environment inside the laboratory meets standards.
