Open one multichannel file with Adobe® Photoshop®. Bear in mind that nT Halftone Channels only works with multichannel images. Start the module nT Halftone Channels from the menu File | Automate | nT Halftone Channels 8.X.X or else with nT neoTextil Panel shortcuts.

The module determines the output resolution size, the Raster Method, and the Curve. When the parameters of the main window are set, push Ok to filter the image in a resulting rasterized multichannel image.


  • 50% Threshold

The raster 50% Threshold is the one which contains 50% black (from 0% to 50%) and 50% white (from 50% to 100%). By selecting the option 50% Threshold, without and with Curve, these rasterized images will be obtained:

  • Pattern Dither 

The Pattern Dither raster uses a squared motive, similar to the halftones for simulating any color that is not found in the color table. When choosing the option Pattern Dither without and with the curve, you will get these rasterized images:

  • Diffusion Dither

The Diffusion Dither uses an error diffusion method that generates a raster that is less structured than the Pattern Dither. Diffusion Dither is a frequency-modulated raster, based on coincidence placement. By selecting the option Diffusion Dither without and with Curve, these rasterized images will be obtained:

  • Halftone Screen

In Halftone Screen a Frequency has to be applied, which means how many lines per inch are required. Round, Diamond, Ellipse, Line, Square, and Cross and the angle of the pattern: e.g. 0°, 22.5°, 45°, 90°, etc. When selecting the option Halftone Screen without Curve and Round Shape, and with Curve and Square Shape, these rasterized images will be obtained:
