Epson new LUT Technology

• Automatically generates the Look-Up Table (LUT)
  for the specific ink technology used
• Optimizes the LUT for the specific ink with
  regards to following factors for best possible
  print quality
• Gradation
• Graininess
• Colour Gamut
• Colour Inconstancy

Factors for better prints - Gradation
Non-smooth gradation
Smooth Gradation

• Nonsmooth gradation gamut shows bad grid
  connection and bad shape. On the other hand,
  Smooth gradation gamut shows good shape and
  smooth transition.
• In order to improve the gradation, the color
  change and ink volume needs to be optimized.
• The print quality is improved by smoother
  gradation. Depending on the LUT, the gradation
  can be improved for the better print quality.

Factors for better prints - Colour inconstancy

• Colour Inconstancy is the phenomenon that
  describes that one colour looks different under
  the different light sources.
• Epson New LUT Technology reduces colour
  inconstancy, ensuring that prints look the same
  when viewed under different light sources
