About 4Plate
4Plate is a group founded in Wuppertal in 2014, formed as a joint venture of C.T.LAY (Italy), Pro Gravur (Switzerland) and PlascoTec (Germany). The group supplies the entire value chain for lamination plates: from plate production and engraving of security features to surface hardening and plasma-based coating. Products are manufactured in stainless steel (4STEEL, 0.6/0.8/1 mm), hardened stainless steel (EXTREMESTEEL up to 500 HV) and nickel-plated/chromated brass (4BRASS, approx. 400 HV). The portfolio includes security engravings such as MLI/CLI lenses, microtext from 15/20 µm, braille to ISO standard, guilloche and 3D shapes of 50–100 µm height, plasma coatings (4SLIDE, 4FLEX, 4SAM-DLC) as well as cassette systems and press pads for lamination presses. The group has been active in the market for over 35 years and supplies the smartcard and ID document industry worldwide. Production sites are located in Germany, Switzerland and France; in 2026 the company was realigned by Pro Gravur and PlascoTec.

Materials & Processes
Stainless steel lamination plates (0.6 / 0.8 / 1 mm)
Standard material for all security features, available in surface finishes from mirror gloss to matt.
Hardened stainless steel (up to 500 HV)
High scratch resistance and longer service life in the card printing environment.
Brass, nickel-plated/chromated (~400 HV)
For very fine engravings and micro-technical applications with high cycle counts.
Aluminium (4KSET / cover plates)
Material for cassette systems and cover plates, with or without coating.
Yamauchi press pad KN22 (up to 180 °C)
Press pad for PVC card lamination without silicone rubber.
Yamauchi press pad YOM02 (up to 250 °C)
For PC/eDP cards with patented "air bubbles" damping structure.
Polycarbonate
Lamination process for PC cards and ID documents.
Plasma coating (4SLIDE, 4FLEX, 4SAM)
Anti-stick and DLC coatings for reduced cycle times, fewer film residues and longer plate life.
