Cheap Color Copy
With the advent of the Xerox machine, the office and work place became a totally different place. Papers could be easily copied in black and white instead of copied in purple by a ditto machine. However as the copy machines advanced more, the demand for cheap color copy
Started to grow. When color copies were first able to be made, they were not cheap, and were often reserved for special purposes. While it is still more expensive the black and white copy, low cost color copy has become a reality.
