With the PlateRite FX870II, UV scattering is reduced during main exposure of the plate.
As a result, the recorder can create true reproductions of the minimum and maximum halftone dot sizes.
This dramatically increases quality in the highlight and shadow areas – areas that are often problematic when using traditional production processes.
The PlateRite FX870II eliminates many of the problems associated with platemaking, including those arising from dust and UV scattering, as well as the many problems inherent in going from film to plate, such as misalignment of the film during platemaking and register errors arising from stretching of the film.
This helps operators get the plate right the first time and reduces the need to repeat plate output.
Plates exposed using the PlateRite FX870II CtP process have highly visible images that are easy to check with the naked eye, enabling plate inspection even before cleaning.
The PlateRite FX870II offers a superior exposure range relative to the UV exposure time, and creates sharp relief patterns that are ideal for the reproduction of fine lines and cutout text.
The PlateRite FX870II were designed to provide productivity in every aspect of the CtP process, from plate mounting to exposure.
At the maximum exposure size of 850 mm x 735 mm (33.4" x 28.9"), a letterpress plate takes just 17.7 minutes* and a flexo plate takes 43.8 minutes*.
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.
By reducing the steps required before printing, the PlateRite FX870II and FX870 helps you use your printing presses more efficiently.
*Productivity varies with the type of media used.
Loading plates is easy. The operator simply clamps the leading edge of the resin plate and then tapes the trailing edge.
This simple plate loading procedure works for all the plate sizes supported by the PlateRite FX870, including the minimum and maximum sizes.
The design of the suction gutters on the face of the drum and the leading edge clamps make it possible for the PlateRite FX870 to handle plates ranging from a minimum of 200 mm x 200 mm (7.9" x 7.9") to a maximum of 870 mm x 762 mm (34.2" x 30").
This makes the PlateRite FX870II perfect for producing the A3 and A4 size plates preferred in the label industry, as well as larger, A1 size plates.
The PlateRite FX870II light source, a multi-channel laser diode, is the same type as the lasers used in CtP recorders for high-end offset printing.
This reliable, proven can-style laser diode quickly exposes the target areas. This type of laser< is both long-lived and inexpensive to operate.
The PlateRite FX870II output processing design makes it possible to use this high-powered laser on the black mask layer of resin plates.
AM screening, which is the form of screening used most commonly in the printing industry today, involves creating halftone dots separated by a fixed distance and arranged in a regular pattern. Varying the size of the halftone dots used creates areas of higher and lower color density. AM screening results in a highly consistent color appearance, and is easy to print.
With traditional AM halftone dots, the reproduction of extreme highlights is inconsistent. In traditional halftone dots, the minimum halftone dot size is one dot, but with Flexo Dot, highlight areas feature a somewhat larger minimum halftone dot size consisting of several dots, which makes it possible to create consistent dots in the extreme highlight areas. The minimum halftone dot shape can be selected from a lineup of shapes for each screen ruling, depending on the platemaking and printing environments, to ensure optimal highlight printing.
Flexo Dot, which is designed for flexo printing, increases the minimum dot size and applies a reinforcing pattern to the base halftone dot shape. This results in the creation of more consistent relief patterns in the highlight areas. The minimum halftone dot shape can be selected from a lineup of shapes for each screen ruling, depending on the plate thickness, platemaking and printing environments, to ensure optimal highlight printing.
Spekta 2 is a next-generation form of hybrid AM/FM screening that is designed to make printing easier. Not only does it solve the problems of moiré and broken lines that sometimes occur when AM screening is used, it also increases the vibrancy of the colors being printed. Spekta 2 makes added-value label printing a reality.
Multi-screening makes it possible to use the optimal type of screening for each object being printed, even if that means mixing different types of screening on a single page. This is particularly useful when printing pages that contain such disparate elements as images, text, keylines, patterned backgrounds, tints, decorative lines, outlined text, and gradations. Multi-screening prevents moiré and broken lines, and contributes to a significant increase in finished quality.
