First:The selection of the ink reduces the leveling of the ink on the film surface after the book is printed. During the batching, no or less dilution or leveling agent is used to promote the formation of the uneven and rough film surface. The professional book printing companies should use special thinners or denatured alcohol for thinning and cleaning. Second:The choice of squeegee, UV ink cannot use a squeegee made of polyurethane, but a special rubber squeegee. The quality of the squeegee pressure is also an important factor that Chinese printer cannot ignore. Because the ink filament is short and thick, the pressure is small, and the ink does not pass through the mesh smoothly; if the pressure is large, the amount of ink passing through the mesh will be too much. Both will affect the book printing quality and the printing effect of imitation metal etching. The pressure of the squeegee should be controlled to be slightly larger than the pressure of printing ordinary color ink.
