The benefits of Spektra

Tuesday 03. July 2012 - Spekta AM/FM hybrid screening technology combines the strengths of both AM and FM screening methods for output on Screen's PlateRite series of platesetters. Not only does it overcome moire and broken lines, it delivers print quality and detail comparable to that afforded by screen rulings of 300+ lpi, and achieves this without requiring any of the stringent print controls normally associated with high screen rulings.

Makes high-quality print more accessible
With Spekta, the quality that can be achieved with an ordinary setup of 175 lpi and 2,400 dpi will appear equal to that of 300 lpi printing. And it can achieve this without the stringent controls usually required for high lpi printing. Higher quality print is achieved with the same printing equipment.
Totally free of moiré
The placement of dots is always random with Spekta, as in FM screening, which means there are no screen angles to contend with. As a result, Spekta avoids the moiré resulting from interference patterns between screen angles and items such as lace cloth, stereo speaker mesh, and CRT screenshots. It also eliminates the rosette moiré that can occur in dark gray or black areas.
Brings out life in the midtones
Spekta does a better job of bringing out the vibrancy in the midtones for skin colors and other areas where true-to-life color is required. Photo images of fresh flowers and fruit, sumptuous meals and desserts-it is easier than ever to reproduce the full appeal of these in print with Spekta.
Superior reproduction of fine details
Spekta demonstrates its superiority in reproducing fine details, such as those required in maps. It improves the rendition of lines that are created with halftones. Because 175 lpi AM screening tends to leave light-colored fine lines jagged and broken, printers must often resort to using spot colors to reproduce them. However, Spekta can reproduce these kinds of images sharply using only process colors. Details such as fine hair and delicate lace are also rendered precisely, without jagged edges.
Taking the benefits of CTP even further
Spekta is supported by our PlateRite series of thermal platesetters. The extremely sharp dots achieved by PlateRite platesetters enable Spekta to produce hybrid screens of the maximum effectiveness.
