This page applies to Harlequin v13.1r0 and later; both Harlequin Core and Harlequin MultiRIP.

The Harlequin RIP supports multiple methods of providing halftone screening, including:

In addition, it includes extensions to those screening mechanisms, including:

  • Harlequin Precision Screening (HPS™), a proprietary mechanism to provide moiré-free screening when using spot functions
  • Functionality to increase the number of gray levels achievable for a given resolution & screen frequency combination
  • Controls to manage the selection of screens when processing live PDF transparency
  • Methods for overriding various aspects of screens set by a job, such as the frequency and the spot shape
  • Automatic selection of screens by object type (HalftoneType 195)
  • Multi-level screening support (for example, for inkjet presses using grayscale heads) with rich options

Harlequin Core can also be integrated with Global Graphics Software's dedicated screening engine, ScreenPro™, which can apply screening at very high speed post-RIP; it can also incorporate PrintFlat™ to correct for non-uniformity in the print.
