RGB revolution: technology and effect pigments for innovative products
Merck thinks beyond boundaries and is revolutionizing the color and printing world with materials and innovative technology for RGB printing, for which a patent application has been filed. Until now, only self-lighting systems such as displays and screens have been able to show the additive RGB color space, in which the three components of light, red, green and blue, combine to form white. Its variety of colors comes very close to the natural color space. However, printing does not make use of light. Printing technologies previously had to manage with the subtractive CMYK color space, in which the components cyan, magenta, yellow and key combine at full intensity to form black, albeit with a lesser variety of colors than RGB. An innovative technology and the four new SpectravalTM effect pigments from Merck, in red, green, blue and white, make RGB printing possible. The result is prints that literally capture light, making the printed image appear with extraordinary brilliance and depth. Drupa visitors will witness a world debut as Merck shows sample packaging with RGB printing for the first time. This new printing technology lends a particularly distinctive, fascinating appearance, not only to packaging of exclusive products, but also to fine shrink sleeves and labels as well as to high-quality brochures, largeformat posters and decorative foils.
