Wallpaper printing

Metal pigments offer a wide range of possibilities for wallpaper design.

Depending on the desired style, design and fashion trends, metallic effects can be used to significantly enhance the attractiveness of wallpaper. The most frequently used process is gravure printing.

Both coarser pigments (for greater brilliance) and innovative effect pigments can be used in rotary screen printing. In addition to the optical effects, important performance criteria for metallic pigments include wear and smudge resistance and general resistance to light, water and atmospheric degradation.

Decomet®

Decomet® is the product name for vacuum metalized pigments (VMPs) by SCHLENK. The manufacturing process makes these pigments extremely thin, and in appearance they are extremely smooth and highly reflective when being applied on foils.

Decomet pigments can be used in sheetfed offset, gravure, flexo and screen printing inks. They can achieve effects similar to those produced with metalized substrates and foils, and because they are non-leafing, the effects can also be tinted with color pigments. Special compositions for water-based and UV curable inks complete the range of this highly attractive product range.
