CMYKvärikoodit

CMYKvärikoodit, also known as CMYK color codes, refers to a system used in subtractive color printing. The acronym CMYK stands for Cyan, Magenta, Yellow, and Key (Black). These four colors are the primary inks used in most color printing processes, such as in inkjet printers and offset printing. The system works by absorbing or subtracting light. When light hits a printed surface, the inks absorb certain wavelengths and reflect others. The combination of cyan, magenta, and yellow inks can theoretically create a wide range of colors, including black. However, mixing these three colors often results in a muddy brown rather than a pure black. Therefore, black ink, referred to as "Key," is added to achieve deeper blacks and more nuanced shades.

In CMYK color codes, colors are represented by percentages or decimal values indicating the amount of each of the four inks used. For example, a pure red might be represented as 0% Cyan, 100% Magenta, 100% Yellow, and 0% Key. A deep blue might be 100% Cyan, 100% Magenta, 0% Yellow, and 20% Key. The specific values can vary slightly depending on the printing device and the color profile used. This system is crucial for ensuring color consistency across different printing outputs and for professional graphic design and print production. Understanding CMYK is essential for anyone involved in the creation of printed materials.
