Halftone Screening is a printing technique used to reproduce a continuous tone image with printer dots. In analogue presses this was achieved with a mesh or screen overlaid on a photographic plate. Digital presses require a digital halftone screen to transform the colors in a document to something that looks right when the final print is viewed.
Your digital press can only represent a very small number of tone values directly; whether you’re using UV, aqueous, EP (toner), latex or any other digital printing technology, we have the tools to help you get the best out of your press, colorants and media.

HDS provides a family of FM/stochastic screens, tailored for different types of reproduction and output device capabilities. It can be used for output using more than four process colorants, i.e. for the standard CMYK process colors, as well as N-color and photo-ink devices.
HDS is also available in five varieties of dot structures or “settings” - from Super Fine to Super Coarse - making it compatible with many different types of output device.
Harlequin Cross Modulated (HXM)
HXM screening merges the best aspects of stochastic and conventional screens giving smooth, noise-free flat tints while retaining fine detail in highlights and shadows. It’s especially valuable when used as a binary screen on devices where extreme highlights can either drop out or become uneven, e.g. many aqueous inkjets.
Harlequin Precision Screening™ (HPS)
HPS is an enhancement of conventional screening that minimizes moiré between separations.
None of HPS, HDS or HXM are subject to the ‘rule’ that limits the number of gray levels to (dpi/lpi)2; You can always achieve more than enough gray levels for clean, artifact-free reproduction.
The Multi-Level Screening provided in Harlequin Host Renderer is typically used with greyscale print heads. Integrated in multi-pass systems or page wide arrays it helps to increases the level of detail that can be retained in the screened result. This achieves the appearance of a much resolution than could be achieved with a binary screen especially at the print speeds associated with high speed inkjet.
Harlequin Host Renderer can also be used with ScreenPro.
Harlequin’s Multi-Level Screening can intelligently promote most binary screens for use in this way.
Of course, Harlequin Host Renderer can also be used with 1-bit (binary) screens, or to generate contone rasters.
Supply your own
If you have your own screening IP, whether that’s as C-code, pre-defined tiles or spot functions, you can integrate it into Harlequin and continue to use it with your devices.
