1. Ink used, UV ink: UV flatbed printers need to use special UV inks, which are generally sold by manufacturers. The quality of UV ink is directly related to the printing effect. Different inks should be selected for machines with different nozzles. It is best to buy directly from the manufacturer or use the ink recommended by the manufacturer. Because the manufacturers and the uv ink manufacturers have carried out various preparations, only the inks suitable for the nozzles can be obtained;
2. Factors of the photo itself: When there is no problem with the UV flatbed printer, it is necessary to consider whether it is the factor of the printed photo itself. If the pixels of the image itself are average, then there must be no good printing effect. Even if the picture is refined, it cannot achieve a higher quality printing effect;
3. Printing material: The operator’s understanding of the material will also affect the printing effect. The UV ink itself will react with the printing material, and will penetrate a certain percentage, and the degree of penetration of different materials is different, so the operator’s familiarity with the printing material will affect the final effect of printing. Generally, materials with high density such as metal, glass, porcelain, and wood are difficult to penetrate; therefore, it is necessary to deal with the coating;
4. Coating treatment: Some of the printed materials need to be equipped with a special coating, so that the pattern can be printed on the surface of the material more perfectly. The treatment of the coating is very important. The first point must be well-proportioned. The coating must be well-proportioned and the color will be uniform. Secondly, the coating must be selected and cannot be mixed. At present, the coating is divided into hand-wiping coating and spray painting;
5. Operation method: The use of UV flatbed printer is one of the factors directly related to the printing effect. Therefore, operators must receive more professional training to get started, so as to print high-quality products. When consumers buy UV flatbed printers, they can ask manufacturers to provide corresponding technical training instructions and machine maintenance methods.
