High Quality and consistent plate quality
The PlateRite FX series eliminate many of the problems associated with platemaking using film, including image unevenness, problems caused by dust, and UV scattering. They also eliminate the many problems inherent in going from film to plate, such as misalignment of the film during platemaking and registration errors arising from stretching of the film. This helps ensure consistent plate quality and reduces the waste inherent in repeating plate output due to errors.
The light source used by the PlateRite FX units, a multi-channel laser diode, is the same type of laser as those used in Screen’s traditional offset CTP recorders. This proven, reliable, high-powered laser images the black mask layer of resin plates. In addition to enabling sharp imaging, the PlateRite FX units’ light source is both long-lived and inexpensive to operate.
Superior reproduction of fine lines and white knockout text
With CtP plates, scattering of the UV light during plate imaging is eliminated, so sharp relief patterns can be created. This ensures superior reproduction of fine lines and white knockout text.
High-quality plate output
Unlike traditional printing plates, CtP plates can include both highlight relief patterns and shadow cutouts, which ensure that the minimum and maximum halftone dot sizes are reproduced accurately. This dramatically increases quality from the highlights to the shadows, across a wide range of image densities.
4,800 dpi resolution for high-quality output
The PlateRite FX series offers a maximum output resolution of 4,800 dpi. This high resolution significantly reduces the incidence of problems common in low-resolution output, such as jaggies in diagonal lines and curves, and dramatically improves the repeatability of fine line reproduction. 4,800 dpi output also delivers smooth gradations, and almost completely eliminates unevenness, even in the highlight areas.
Leading and trailing edge clamps save the operator time and trouble when 1,067 × 1,524 mm (42.0” × 60.0”) plates are used. The PlateRite FX1524 features a button operated loading mechanism, which loads plates reliably. Manual plate loading is also available, and the operator can choose the optimal plate loading procedure depending on the size of plate being used. Note: The minimum supported plate size is 200 × 200 mm (7.9” × 7.9”).
For letterpress and flexo printing
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 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.
Letterpress and offset 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 (option) 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.
