意味と目的
5.1 Quality standards for artist paints require the assessment of various appearance characteristics of the paint film. The determination of colouration strength (test method D4838) specifically requires preparation of the drafting for colorimetric measurements. Other evaluations, such as color designation, 透明性, 光沢, and chromatic aberration measurements, also require a retracted sample.

5.2 アーティスト’ tube paints have a pasty consistency, which makes it difficult to use traditional methods of film application, especially for dry oil paints.

5.3 The artist’s pigments differ in two attributes that are important for film preparation, namely transparency and drying time. Colorimetric determination and some other types of evaluation require paint specimens that completely conceal the substrate. Very transparent coatings require such a thick film to produce a complete masking effect that the drying time is too long or the surface of the specimen is defective. When complete concealment is required, this practice aims to provide opaque films without these defects by applying a series of films.
