The colour space of the ceramic paints used for photoceramic production is narrower than the range of the colours possible to obtain with regular toners and visible on the monitors. Moreover the monitors emit the light that increases saturation and vibrancy of the colours. It is impossible to obtain some of the colours without sacrificing the durability and UV-light resistance. The experience of the graphic designers specializing in the photoceramic toners gives us the possibility to obtain the most similar colours and the difference is almost unvisible to the customers.
