The additive synthesis
When we talk about additive synthesis, we refer to the primary colours produced by light. These primary colors are red, green and blue. This hat trick is known as RGB. They are the center and the two ends of the spectrum of visible light. If mixed together, white light is created.
The subtractive synthesis
With subtractive synthesis, we refer to the primary colors of pigments. Every surface, every object, every single thing, absorbs only some of the wavelengths emitted by light and, in response, reflects others. The pigment we perceive is therefore given by the colours subtracted from the white light that we perceive. The main colors of subtractive synthesis are: cyan, magenta, yellow (CMY). With the sum of the three you get black (K).
But why, in the press world, do we talk about CMYK as a whole?
Because in nature the black we see is never pure, and then in the pigments used in the print is added a black artificial pigment (K), to recreate the pure black. These are the reasons why everything that appears on the displays should be created in RGB (because all these devices produce light); while all the printed is produced in CMYK (because the printing is made from the mixing of pigments).
The final quality of a printing product is therefore the result of careful and precise pre-printing work. Our works are characterized by numerous color tests in the printing machine, and all the corrections that can serve for a precise and perfect result.
