This type of printing is a direct relief printing process that uses flexible printing plates. The printing areas are higher than the non-printing areas. The principle is comparable to a stamp. This printing technology is currently experiencing the most rapid development. Flexographic machines are structurally simple, reliable, and economical. With proper maintenance of raster rollers and adherence to ink management principles in the preparation of printing forms, this technology is optimal for label and packaging production.
New quality possibilities are also offered by the "HD flexo" technology, whose results are comparable to offset printing. Typically, up to a 1% dot is printed and a raster of 60 lpcm, or for a more pronounced effect in light motifs, a stochastic raster is also used.
