- Duotone - a halftone reproduction of an image using the superimposition of one contrasting colour halftone (traditionally black) over another color halftone. This is most often used to bring out middle tones and highlights of an image. The most common colors used are blue, yellow, browns and reds.
- Spot Colour - In offset printing, a spot color is any color generated by an ink (pure or mixed) that is printed using a single run. Offset technicians around the world use the term spot color to mean any color generated by a non-standard offset ink; such as metallic, fluorescent, spot varnish, or custom hand-mixed inks.
- Monochrome - paintings, drawings, design, or photographs in one color or shades of one colour. A monochromatic object or image has colors in shades of limited colours or hues. Images using only shades of grey (with or without black and/or white) are called grayscale or black-and-white.
- Tint - is the mixture of a colour with white, which increases lightness, and a shade is the mixture of a color with black, which reduces lightness. Mixing a color with any neutral colour, including black and white, reduces the chroma, or colourfulness, while the hue remains unchanged.
- Pantone - world renowned authority on colour and provider of colour systems. The Pantone name is known worldwide as the standard language for colour communication from designer to manufacturer to retailer to customer.
