# Out with the old, in with the new!

In 2006, we successfully installed the first generation of the StencilMaster STM-1621 at a customer's site. Even after 18 years, the system is still in operation, consistently exposing screens with satisfactory quality.

In 2006, we successfully installed the first generation of the StencilMaster STM-1621 at a customer's site. Even after 18 years, the system is still in operation, consistently exposing screens with satisfactory quality.

Today, after all these years, it's time for an upgrade to the latest SignTronic StencilMaster Generation 4\. Equipped with the newest LED light source, LED\_Q4, the new STM-1620 is packed and ready to be shipped.
