If you want to print a certain color but only want to use one printing ink, you use a spot color. Spot colors are primarily used when you want to print certain colors that are hard to reproduce with regular four-color printing or if for some other reason you want to avoid screen percent value combinations with four-color print. Pantone and HKS are two systems for spot color.
The Pantone Matching System (PMS) is a useful but somewhat inaccurate way of describing colors. Pantone colors are frequently designated for a company’s color profile and logo to ensure consistency and are widely applied in packaging printing.
What is Pantone Color ?
The Pantone model is based on the combination of nine different colors that were selected on the basis of their usability and hue. Every shade in the system is composed of a defined combination of the nine basic colors. The colors have been named according to a number system that makes it easy to select a shade, and the Pantone system incorporates a total of 114 different colors. Pantone sells color guides printed on different papers and other materials so you can choose the color you want or see how a certain Pantone color will look on a given material.
Pantone to CMYK
A color model such as Pantone, which uses unique pigment combinations for each color, has a greater ability to depict saturated colors. For example, a light yellow color in a Pantone model actually is a light yellow pigment–you don’t have to fool the eye with screen percent values, as with the CMYK model. When converting from Pantone to CMYK, be aware that you cannot re-create all the colors from the Pantone model.
A typical example is when you print an advertisement in a newspaper. As a rule, newspaper printers can only do four-color printing, even if colors are normally defined in Pantone colors. To predict how a Pantone color will look when it is printed in four-color, Pantone has produced special Pantone-to- CMYK guides. These contain Pantone colors printed with Pantone inks next to their corresponding four-color example so that you can see the differences clearly. Some colors remain quite similar, while others vary greatly–for example, blue, green, and orange hues.
What is HKS ?
HKS is a color system that, like Pantone, is based on different pigment combinations for each color. It is mainly used in Germany, where it is morecommon than Pantone. The HKS System is based on 88 physical colors, each with 39 shades, totaling 3,520 colors. Exactly like the Pantone system, there are printed color guides on coated and uncoated papers, and each color has its corresponding number.
