SPOT COLOUR

Print technicians around the world use the term spot colour to mean any colour generated by a non-standard offset ink; such as metallic, fluorescent, spot varnish, or custom hand-mixed inks. (as opposed to obtaining a colour by via mix of cmyk)

GREYSCALE

One colour black and all the shades of grey through to white (black and white photography is grey scale)

MONOCHROME (mono)

Monochromatic colours are all the colours of a single hue derived from one colour and extended using the shades,tones and tints of that colour.

HALFTONE

This is a mechanical process (as opposed to chemical) for converting tonal values into a series of dots that although solid dots, when printed give the impression of continuous tone.

RICH BLACK VS NORMAL

Rich black, in printing, is an ink mixture of solid black over one or more of the other CMYK colors,^[1] resulting in a darker tone than black ink alone generates in a printing process.

A typical rich black mixture might be 100% black, 50% of each of the other three inks. Other percentages are used to achieve specific results, for example 100% black with 70%cyan, 35% magenta, and 40% yellow is used to achieve "cool" black. "Warm Black" is 100%K 60%M 60%Y and 35%C.

DUOTONE: 
Duotone is a halftone reproduction of an image using the superimposition of one contrasting color halftone (traditionally black) over another color halftone.
