Introduction

The Lotem^® 400 platesetter is a thermal imaging platesetter. It represents state-of-the-art technology within all operational systems, and features a technological breakthrough in the form of a multi-beam, variable resolution thermal imaging head. The Lotem 400 w/ MCU platesetter (with the automatic loader) provides full automation including slip sheet removal, customized plate punching, and plate loading/unloading. It has a fast rotating external drum and a thermal imaging head. The Lotem 400 can plot any plate size from 381 x 318mm (15 x 12.5 inch) for older models or 229 x 311 mm (9 x 12.25") for newer models (small) to 750 x 622 mm (29.5 x 24.5 inch).

The thermal imaging head inside the Lotem 400 is comprised of a 24 laser beam array operating at a wavelength of 830 nanometers.

Individual beams are precisely positioned using a self calibrating alignment configuration, and this allows for continuously variable imaging resolutions.

A significant and unique feature of the Lotem 400 is dynamic drum balancing. This ability guarantees rotational stability of the external drum while imaging any size plate within the specified size range, from a minimum of 381 x 318mm (15 x 12.5 inch) for older models or 229 x 311 mm (9 x 12.25") for newer models (small) to 750 x 622 mm (29.5 x 24.5 inch).

To allow for variable resolution imaging, drum rotation speed is programmed to vary proportionally with the output resolution. This particular feature is unique to Lotem 400 platesetter, and ensures optimized imaging speeds based on output parameters.

The Lotem 400 front end is Brisque Impose software version 3.In addition to standard Brisque Impose features, special features for CTP users, such as fast plate remake and back/front preview were added.

The Lotem 400 platesetter system can accept data from any standardized digital file format including PostScript™, EPSF, PDF™, TIFF-IT, and CreoScitex CT/LW files.
