Screen claims its new PlateRite FX870II is the world's first flexo platesetter to offer a maximum resolution of 4,800 dpi as a standard feature. This high resolution significantly improves the smoothness of curves and diagonals, and its reproduction of fine lines and small text is outstanding, the company states. Gradations are said to appear smooth, especially in the highlights.
The use of combination presses is becoming more widespread in the packaging and labels industries in order to deliver fast turnaround products at high speed. Therefore there is an increasing need for prepress equipment that offers both better quality and increased productivity. Designed to meet these growing needs, the PlateRite FX870II features a newly developed high output recording head and an auto-balancing function said to ensure stable drum rotation.
Screen' says its proven thermal laser technology can image advanced digital plates from a variety of leading manufacturers, producing consistently high quality. Plates can be loaded in any size from 100 x 100mm up to 870 x 762mm without any extra handling or masking of the drum.
The elimination of intermediate production steps involving film also frees the operator from time consuming tasks such as preparing the film, step-and-repeat operations, and imposition work. To further improve productivity, the unit also features a clamp said to make plate loading simple and efficient, as well as a variety of other mechanisms that make the unit extremely easy to operate.
Flexo Dot is a new system of halftone dots from Screen, designed to improve the highlight areas in flexo and letterpress printing. It features a minimum halftone dot size of several dots, as opposed to the conventional halftone dot comprising a single dot.
By applying a reinforcing pattern to the base halftone dot shape, the relief patterns in the highlight areas are more consistent, it is claimed, allowing more control and crisper images. It also provides a greater range of gradation, as the minimum halftone dot shape can be selected from three available types to suit the specifics of the highlight printing according to the plate making environment, inks and media.
