23 Fotospeed Device Dependent Colour RGB & CMYK numbers are dependent upon their method of reproduction.

24 Fotospeed Device Dependent Colour RGB & CMYK numbers are dependent upon their method of reproduction. Each RGB monitor will display the same RGB values differently.

25 Fotospeed Device Dependent Colour RGB & CMYK numbers are dependent upon their method of reproduction. Each RGB monitor will display the same RGB values differently. Each inkjet printer will produce different colours from the same RGB values.

26 Fotospeed Device Independent Colour What is needed is a method of reproducing colour that is not dependent upon the device in use.

27 Fotospeed Device Independent Colour What is needed is a method of reproducing colour that is not dependent upon the device in use. A controlled environment that allows colour reproduction accurately on any monitor and printer.

28 Fotospeed What is a Profile?

29 Fotospeed What is a Profile? A description of the colour a device is capable of seeing, displaying or printing.

30 Fotospeed What is a Profile? A description of the colour a device is capable of seeing, displaying or printing. Simply put, a profile is a label or tag that describes the colour of a particular image or device.

31 Fotospeed Colour Management System The Colour Management System ensures that the colour description in an input colour space is transferred faithfully to an output device.

32 Fotospeed Tagged or Untagged An image (or device) can be in one of two states.

33 Fotospeed Tagged or Untagged An image (or device) can be in one of two states. Profiled – ‘Tagged’

34 Fotospeed Tagged or Untagged An image (or device) can be in one of two states. Profiled – ‘Tagged’ Or Unprofiled – ‘Untagged’

35 Fotospeed Profile Types A profile can be one of two types:

36 Fotospeed Tagged or Untagged A profile can be one of two types: Generic or Bespoke
