Bellissima DM Screening

Digitally Modulated Screening for Flexo Printing

Bellissima (Italian for most beautiful) DMS is Hamillroad’s Digitally Modulated Screening for Flexo. Bellissima DMS, the ultimate in flexographic screening, delivers a previously unobtainable level of image reproduction for flexo. Rivaling the quality of print typically associated with offset and gravure, Bellissima DMS is challenging digital as the future for flexible packaging and labels.

Innovative flexo technology

Bellissima Digitally Modulated Screening utilizes innovative technology that’s a fusion of the best characteristics of AM, FM, XM, GS and CS screening while avoiding their limitations and problems. It dramatically enhances the quality and stability of flexo presswork.

Digital modulation (DM)

This unique screening digitally modulates every pixel it produces thereby precisely controlling the dots in each separation while its “stochastic rosette” interleaves the screens in the separations to eliminate noise and moiré. In addition, the stochastic rosette maximises the ink-on-paper area and minimizes the amount of ink-on-ink, to expand the available color gamut while eliminating color shifts due to misregistration.

The screening analyzes each pixel to ensure that no dot is too small to plate or print but is not large enough to be visible. Dots are created in a carefully controlled manner, to ensure detail is placed exactly where it is needed, vignettes are smooth and flat tints are ‘flat.’ The result is a quality of print, particularly on flexible substrates, that was previously unobtainable.

Overcoming flexo printing press machine problems

Bellissima DM Screening helps to extend the life of a flexographic printing press. Using Bellissima’s patented dots, common printing problems including bounce, barring, and slur are significantly reduced and, in some instances, completely eliminated.

With ever shorter run lengths, the ability to match and even exceed the print quality of gravure, Bellissima DMS will allow us in the flexo printing industry to meet the ever-increasing demands of brand owners for higher quality print at an economic cost.Nick Smith, Managing Director, Parkside Flexibles, UK

We were the first in the world to test Bellissima and the first time it went onto press, we knew this would be the screening that changed the flexo industry. As Bellissima has evolved it has gone beyond just improving print quality by addressing problems inherent to the flexo process.Gavin Jones, Technical Director, Syreline Process, South Africa

Compared with AM Screening

Bellissima DM Screening uses specially shaped dots that, like an AM screen, minimize problems with dot gain variation and are easy to control on press. However, unlike an AM screen, Bellissima DMS does not suffer from problems such as highlight dot loss, moiré or lack of image detail.

Compared with FM Screening

Like an FM screen, Bellissima DM Screening produces a stunning level of image detail, equivalent to 350-450 lpi for offset printers. However, unlike an FM screen, Bellissima DMS does not suffer from problems such as noisy flat screen tints and variability on plate and press.

Compared with XM (hybrid) Screening

Bellissima DM Screening precisely controls the size of its highlight and shadow dots which, like an XM screen, enables retention of a full tone range of 0-100%. However, unlike an XM screen, Bellissima DMS does not suffer from problems such as moiré, or noisy flat tints and color shifts with misregistration.
