Photographic special effects in an unlimited number of colours are the product of three- and four-colour printing, a process Menphis has developed to create exclusive new special effects produced using acid colours which react to four-colour designs on a polyester weft and on natural fibres such as wool, silk or cotton. These processes also permit creation of marbled effects. Menphis S.p.A. updates its technologies and comes up with innovations in its research laboratories to stay in the forefront of the evolution of increasingly sophisticated special effects for the Fashion market.
