The RGB color model is an additive color model in which red, green and blue light are added together in various ways to reproduce a broad array of colors. The name of the model comes from the initials of the three additive primary colors, red, green and blue.


The CMYK color model (process color, four color) is a subtractive color model, used in color printing, and is also used to describe the printing process itself. CMYK refers to the four inks used in some color printing: cyan, magenta, yellow, and key (black).


The Pantone Color Matching System is largely a standardized color reproduction system. By standardizing the colors, different manufacturers in different locations can all refer to the Pantone system to make sure colors match without direct contact with one another.


Web colors are colors used in displaying web pages, and the methods for describing and specifying those colors. Colors may be specified as an RGB triplet or in hexadecimal format (a hex triplet) or according to their common English names in some cases. A color tool or other graphics software is often used to generate color values. In some uses, hexadecimal color codes are specified with notation using a leading number sign (#).


RAL is a colour matching system used in Europe. In colloquial speech RAL refers to the RAL Classic system, mainly used for varnish and powder coating but nowadays there are reference panels for plastics as well.

AI: Adobe Illustrator

Native Adobe Illustrator source file format. Vector drawing program used by designers and commercial printers to generate files of different file formats and sizes.

BMP: Bitmap

BMP is a standard image format on DOS and Windows-compatible computers. BMP format supports RGB, Indexed Color, Grayscale, and Bitmap color modes.

JPEG/JPG: Joint Photographic Experts Group

JPEG och JPG standard image format and the most popular one used on the web (low resolution). It is also used in print (high resolution) Is the preferred format for photographs. JPG files are also smaller in size as compared to other image formats. But if compressed repeatedly the overall quality of a JPG image is reduced. JPEG format supports CMYK, RGB, and Grayscale color modes, but does not support alpha channels.

PDF: Portable Document Format

PDF is an open source, universal file format developed by Adobe Systems that preserves and embeds fonts, images, layouts and both vector and bitmap graphics of any source document. PDF files can be shared, viewed and printed by anyone with the free Adobe Reader software. Some PDF files can be used for commercial, digital, and/or desktop printing.

TIFF / TIF: Tagged Image File Format

TIFF/TIF is the standard file format for high-quality images and is commonly used in professional environments and commercial printing. TIF formats are considered to be the most reliable format supporting CMYK, RGB, Lab, Indexed Color, Grayscale, and Bitmap color modes. TIF is a flexible bitmap image format supported by virtually all paint, image-editing, and page layout applications.

EPS: Encapsulated Postscript

Encapsulated PostScript (EPS) language file format can contain both vector and bitmap graphics (raster) and is supported by virtually all graphic, illustration, and page layout programs. The EPS format is used to transfer PostScript-language artwork between applications. EPS files are the preferred format for design professionals to transfer an image or artwork into another application. Vector files are scalable to any size without degradation since the image software uses a technique called vectoring to create the image.

PSD: Adobe PhotoShop Document

PSD is the native Adobe PhotoShop file format and industry standard bitmap graphics program used by professional designers and printers. PSDs are typically raster files made up of tiny dots (pixels), that when enlarged or reduced significantly in size, lose quality.

GIF: Graphics Interchange Format

A GIF is a low resolution graphic file format most commonly used for web and email purposes. Almost all browsers can support the use of GIF files, which use a compression scheme to minimize file size and electronic transfer time. This format is not appropriate for most photographs because it can record a maximum of 256 distinct colors.

PNG: Portable Network Graphics

PNG files are high-quality bitmap images that employ lossless data compression. PNG was created to improve upon and replace Graphics Interchange Format (GIF) as an image file format not requiring a patent license. Unlike GIF, PNG supports 24-bit images and produces background transparency without jagged edges.
