The manufacturing process for PVC edge banding involves first printing ink onto a PVC substrate, followed by roller-coating with UV varnish for curing. Achieving a realistic simulated effect hinges critically on the quality of the ink used. Market prices for ink vary significantly, ranging from 20 to 160 yuan per kilogram. By selecting high-quality ink, the resulting edge banding exhibits an exceptionally high degree of realism and rich visual depth, with negligible fading observed over a three-year period in indoor environments. Currently, the production of edge banding with rich visual depth primarily utilizes three-color printing, followed by two-color and single-color printing methods.
To assess ink quality, edge banding samples printed with different inks can be exposed to direct sunlight for one week; these samples are then compared against their pre-exposure counterparts to observe the extent of any fading. Concurrently, the quality of the UV varnish also directly impacts the abrasion resistance and transparency of wood-grain edge banding. Market prices for UV varnish range from 50 to 120 yuan per kilogram; if the surface of the edge banding is prone to scratching or appears cloudy, it is likely that inferior-quality UV varnish was utilized.
