Flint Group develops laser ablative dry film

In cooperation with Swiss company Folex, a manufacturer of films and paper used in current imaging technologies, Flint Group Flexographic Products has developed a laser ablative dry film.

The laser ablative dry film, LADF, is designed for imaging on infrared laser systems, such as digital flexo or letterpress image setters. The imaged film can be used for the UV exposure of analogue flexographic, letterpress and offset plates, as well as for screen printing stencils and for image control.

The new LAD film is claimed to offer numerous advantages to the user. Due to the very high resolution (>10.000 dpi, depending on the laser system) as well as the high contrast and the reproduction of even the finest details, it is suitable for almost all applications.

The matte film surface enables the exposure of small size pad printing plates up to large size flexo printing plates. The thickness of 175 microns ensures good handling properties and a high dimensional stability. The LADF film minimizes the process tolerances and allows a reliable and repeatable quality in film processing. In addition, the film exhibits ‘outstanding’ scratch resistance, says the company.

After ablation, no further processing steps are required; there is no need of chemicals such as developer or fixative, and no cleaning is necessary. The LADF film can be handled in daylight, so there is neither a need for a darkroom nor for UV protection. The new film is suitable for all standard IR lasers used in flexo and letterpress applications; therefore, no additional investments are required.
