Native imaging - dithering algorithm options

Relativity native imaging offers multiple dithering algorithms you can apply towards imaging your documents.

This topic provides details on the various dithering algorithms available within Relativity native imaging, as well as use cases for each algorithm, including the size and clarity of images you create.

Dithering algorithm details

System admins can select from one of eight different dithering algorithms when they choose to image with native imaging:

  • Clustered 6x6
  • Clustered 8x8
  • Clustered 16x16
  • Dispersed 4x4
  • Dispersed 8x8
  • Dispersed 16x16
  • Floyd & Steinberg
  • Threshold
