In the process of flexo printing, the processing of details is very important. In order to ensure the quality of the flexographic printing machine, what are the details that are often overlooked in the production process?
The drying device of the flexographic printing machine is divided into two stages: one level is inter-color drying, that is, the front color ink layer is dried as completely as possible before entering the next printing unit, and the other level is final drying, that is, all the inks in each color. After printing, the solvent in the ink layer should be completely eliminated to avoid filth failure during rewinding or stacking. Keep the drying system clean. The flexo process using UV flexo inks requires a strict working environment. If the working environment is in poor condition and the special working space has a low plot, the better drying device will not achieve satisfactory drying effect. Replace the UV lamp in time.The UV lamp life of a flexographic press should be used at the rated life specified by the manufacturer. When it exceeds its rated life of 1000-2000 hours, the lamp should be replaced even if the lamp still emits light, because the ability of the UV lamp to emit a UV lamp is far from satisfactory. The reflected light device must be kept clean and the mirror should be highly polished to improve reflection. Therefore, keeping the reflector clean is a prerequisite for ensuring reflection. When using UV flexo inks of flexographic printing presses, attention must be paid to radiation protection, which is harmful to the human body. In fact, the UV light energy is relatively small, and a UV or the like can be appropriately closed or covered with a thin film of lead material or the like.
Therefore, in the printing process of the flexographic printing machine, it is necessary to pay attention to these details to ensure its good performance and ensure good printing results.
