We are your specialist for Computer-to-Screen direct exposure

Are you still using film for working and copying? And are you looking for alternatives to counteract the continuously rising film expenses and considerable quality losses?

Our CtS direct exposure technology is the alternative you have been looking for.

These are your advantages at a single glance:

FILM-FREE screen making without vacuum frame and without copying lamp; considerably shorter process sequences; a reduced number of work steps and as a result lower costs per screen printing form. Our direct exposure technology enables you to save time and money.

The technology is based on the following component modules:

Strong UV light source
DMD micro-mirror array
High-quality ZEISS optics with self-focusing
Control unit OECU and operating software STPrint V.4
Servo-motors for multiple axis control
Horizontal exposure carriage with air-cushioned shuttle

This CtS direct exposure technology is developed and manufactured by our company in the well-known Swiss quality.

The quality of the used optical equipment is of prime importance for excellent exposure results. As we categorically refuse to compromise in this field, we only rely on the high-quality "Optics by ZEISS".
Strengths of the Zeiss optics: fast lenses with high light transmission, maximum stability and precision.

The optical engine OE guarantees an industrial direct exposure and comes in two resolutions:

1270 dpi (pixel size 20 micron)
2400 dpi (pixel size 10 micron)

The decisive advantage is that - even after many years of use and countless cleaning and maintenance services - the selected resolution remains stable and unchanged!

The core of the new third generation of CtS direct exposure systems developed by our company is the OECU (Optical Engine Controller Unit).

Our research and development specialists have systematically implemented their long-standing experience in the field of CtS technology and thus set new standards. The OECU as the central control unit interlinks all the processes for the exposure head. This unit not only controls DMD's of the latest generation but also the high-precision drive units for the X- and Z-axes.
