What is the Four Colour Process Printing - What is four colour process printing??

Accepted Answer

A method of multi-colour printing  this process uses four process colours that are combined to create the required colours  Sometimes known as process printing  this process involves layering the required process colours onto a substrate in multiple runs to produce the correct colour  The four colours are Cyan  Process Blue   Magenta  Process Red   Yellow  Process Yellow   and Key  Black          The CMYK model creates colours through a subtractive combination of process colours  starting with white  each process colour that is added will absorb certain wavelengths  colours  of light rather than reflecting them  subtracts them from white          In order to be able to produce a continuous range of colours  process colours are printed as halftones  tiny dots of colour   The dots are so small that the human eye perceives a pattern of dots as a solid colour  by adjusting the size  shape  and spacing of the dots  the saturation of a process colour is increased or decreased  allowing a continuous range of colours to be produced  The inks and toners used in process printing are usually translucent  this allows the process colour to be layered as needed  Colours are usually specified and identified by listing the percentage of a halftone that is printed in each process colour  if a process colour isn't required  it is listed as 0           While four colour process printing can produce a wide range of colours  and is used for full colour printing   it is reliant on the optical effect of halftones and the combination of just four colours and simply cannot produce a full  unlimited range of colours  To expand the range of colours that can be produced  different versions of process printing may be used  Pantone's Hexachrome model expanded the range of CMYK by adding two more process colours  orange and green   and the CcMmYK process adds a light cyan  lower case c  and a light magenta  lower case m  to overcome problems with printing light shades of these two colours
