At the heart of the Auraia screening engine are a number of breakthroughs in technology which eliminate the issues of dot gain and the problems that result from that.
The carefully controlled dots produce prints equivalent to a traditional 400-500 lpi screen for commercial printers and a 200-250 lpi screen for newspaper printers, with incredible detail throughout an image, as well as hilite & shadow detail rarely seen before. In addition though, it’s easy to plate and print.
The Auraia screening is available as a plugin for the popular Harlequin RIP; versions 8.3, 9 and 10 (both 32 & 64 bit) of the RIP are supported on Mac and PC which provides genuine 16 bit screening offering an incredible 50,000+ levels of gray per color.
Installation is easy and is performed by simply printing a PostScript file and rebooting the RIP, as is activating the screening (which is linked to the RIPs dongle). The screen is then selected from the Harlequin RIP’s ‘Separation Manager’ ‘Edit Style’ just like any other screen.
Plate calibration should be performed as usual, although we recommend using an ‘FM’ mode on a plate reader if available. The XRite iCPlate2 has been extensively tested and is the recommended plate reader to use.
Press calibration is also required, as the ink savings inherent in the screening are produced as a result of the small dots that are used and these will produce different gain on press when compared to conventional screening. This is most certainly required if printing to a standard such as ISO 12647-2 or G7 for commercial printing or SNAP for newspaper printing.

Auraia DM Screening uses specially shaped dots that like an AM screen minimises issues with dot gain and is easy to control on press. Unlike an AM screen though, it does not suffer from problems such as hilite dot loss, moiré and a lack of image detail.
Like an FM screen, Auraia DM Screening produces a stunning level of image detail, equivalent to 200-400 lpi for newspaper printers and 400-500 lpi for commercial printers. Unlike an FM screen though, it does not suffer from issues such as noisy flat tints and (a lack of) consistency / controllability on plate / press.
Auraia DM Screening precisely controls the size of its hilite and shadow dots which like an XM screen allows it to retain a full tone range of 0-100%. Unlike an XM screen though, it does not suffer from issues such as moiré (at 200 lpi or below), or noisy flat tints and color shifts on mis-registration (both of which occur as the lpi is increased above 200 lpi to 300 lpi and beyond).
Like a GS (Geometric) screen, Auraia DM Screening uses carefully crafted geometric shapes that improve the stability on press and eliminate issues such as rosettes and color shifts. Unlike a GS screen though, it does not suffer from issues such as moiré clashes with image content or a lack of image detail.
Auraia DM Screening uses specially shaped dots that like a CS (Concentric) screen minimizes ink build-up on dots and so maximises the amount of light filtered, thus saving a significant amount of ink. Unlike a CS screen though, it does not require high-end plates to hold tiny pixel shapes that suffer from wear.
