Decoration Without Decoration

Abstract

This paper discusses the technique of “decorating without decoration” for plastic products. Traditional plastic decoration methods such as painting, printing, and plating aim to enhance appearance and tactile quality, but in recent years approaches leveraging the material's inherent color and surface geometry have gained attention. “Decorating without decoration” refers to techniques that use coloration and texture to impart a high-quality, premium feel without adding any external decorative layers. This approach is also significant for its potential to reduce environmental impact and to facilitate single-material (monomaterial) product design. The paper outlines the evolution of plastic decoration techniques and introduces specific “decorating without decoration” methods along with the molding technologies underpinning them.
