A colour is described as opaque if it is non-transparent or impermeable to light. As a rule, this means that light cannot shine through the colour and no objects or colours are visible behind it.
The opacity of a colour depends on various things such as the type of material or medium used, the thickness of the paint layer and the type of paint. Some colours can be naturally opaque, while others are the opposite of opaque, namely transparent or translucent.
Opaque colours are used to achieve an impermeable and opaque effect. They are used, for example, in the design of art, in prints or in the application of paints and coatings to achieve complete coverage and uniform colour reproduction.
The opacity of a colour is also associated with terms such as transparency, translucency and see-through.

Precise proofing of tonal values of spot colours

If the paper or paper class is known and defined, a measuring standard such as M0/M1/M2 has been established and the content of optical brighteners … read more
