There are several degrees of transparency depending on the technologies and materials used. The opacity can also be manually adjusted by polishing, sanding, or pigmentation.

The pigmentation process makes it possible to produce pieces naturally colored in the mass of certain plastics. It is possible to choose the desired RAL or Pantone, with color pigments mixed with the material. This is applicable for rigid or flexible parts.

A paint finish that enhances the surface condition both functionally and aesthetically. It is possible to achieve different effects of appearance: satin, matte, gloss, or semi-gloss.
