SignTronic reinforces their international sales team
Screen printing is alive and well – a fact that has become more and more apparent during the past months in which we have noticed increased investment activities in new technologies and automation processes.
The professional and automatic preparation of printing screens plays a key role in this industry where the decision-makers are getting aware of the fact that only THE PERFECT SCREEN will enable them to live up to the present extremely high requirements of the various markets and sectors. Based on the present state-of-the-art CtS direct exposure systems designed by SignTronic, we have for many years successfully dedicated ourselves to topics such as CtS TECHNOLOGY & SCREEN AUTOMATION.
Different chemical photo-reactive emulsions are used in screen printing for stencil production. Depending on the bandwidth, optical power and depth of field from the optical system, the reaction / exposure speed has a diverse value. In this paper the emulsions get categorized and validated in a first step. After that a mathematical model gets developed and adapted due to heuristic experience to estimate the exposure speed under the influence of digitally modulated ultra violet light.
