In the process of making glass bottles, we usually need to use a lot of deep processing techniques to decorate our glass bottles. The following is a description of the processing process on several bottles: Silk screen Printing: Pour the ink into the pre-engraved stencil, then copy the text or pattern to the surface of the product. Mainly applicable: generally suitable for printing with little plane or curvature. Easy problems: oil, flying oil, color difference, deviation, exposed bottom, sand hole, lack of circle, deformation. Observation method: Appearance visual inspection, with force test, deoiling test. 
Pad printing: Surface printing is to put the ink into the engraved text or pattern intaglio, then copy the text or pattern to On the flexible rubber head, the pattern on the rubber head is transferred to the surface of the product, and finally irradiated by heat treatment ultraviolet light. The method of curing the ink. Mainly applicable: Suitable for most flat and curved products, and high precision product surface Easy problems: oil, flying oil, color difference, deviation, exposed bottom, sand hole, lack of circle, deformation 
UV COVER: Apply UV oil to the screen or pad printing surface, then heat treatment or UV irradiation.Method to cure the ink. Mainly applicable: Applicable to all screen printing and pad printing printing surfaces with high adhesion or effect treatment Easily problematic: Luminance does not match (UV sub-light and light), oil leakage, burrs, etc. Observation method: mainly to see, the brightness, UV oil is uniform, whether there is burrs, etc. Spray paint: spray the diluted paint on the surface of the product with a spray gun, and then pass a certain heat treatment method. Curing the ink Mainly applicable to: most plastic products, wood products. Easy problems: oil, flying oil, color difference, less oil, oil accumulation, paint falling. Observation method: Appearance visual inspection, with force test, deoiling test. 
Baking paint: It means that the product is baked at the proper temperature after spraying to make the paint stronger. Mainly applicable: high plastic products. Easy problems: oil, flying oil, color difference, less oil, oil accumulation, paint falling. Observation method: Appearance visual inspection, with force test, deoiling test. Hot stamping: using a color foil or a hot mold engraved with a pattern or font, under controlled temperature and pressure, on the surface Method for manufacturing color embossed pattern or font. Mainly applicable: generally suitable for printing with small plane or curvature, or paper surface. Prone problems: not wear-resistant, and the compatibility of the surface on aluminum foil will affect its printability. Observation method: Appearance visual inspection, with force test, deoiling test. 
Laser printing: laser printing technology uses the high energy of laser to directly print text and patterns onto the surface of materials. Printing method. The basic principle is that the laser will be absorbed by the irradiated material, and the absorbed laser energy will be converted into thermal energy. Or cause optical reaction to decompose, evaporate, carbonize, discolor, foam, due to the surrounding and color and surface state, Mainly applicable: Suitable for all kinds of plastic surfaces, or iron and aluminum surfaces Easily problematic: not easy to be worn, printed or low cost, but generally only black effect, no silk screen on the surface, etc. And the color is light and the depth of the line is not well controlled.
