Bellissima 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.
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 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.
