The demand for an inline exposure and development system for screen printing with a computer-to-screen system (CTS) has been answered by Lotus Holland. Lumenator II is a practical UV-LED exposure and development system for screen printing.
Homogeneous and even distribution of light
Lotus’ Lumenator II is used for the fast exposure and development of screen printing stencils made with CTS systems, such as Exile Spyder or M&R i-Image S. The LED light ensures a homogeneous and even distribution of the light, while exposure times are set via a touch-screen display and can be stored. As compared to using conventional methalhalide lamps, the use of LED lamps not only save energy, hardly producing any heat, but the lifetime of the UV LED light source is extremely long. Lumenator II is ensured of edge-sharp development with up to six water nozzles. It is suitable for screens with a maximum size of 90cm x 70cm, and with its vertical construction, it requires less space.
Accelerates stencil production and increases productivity
Using Lumenator II has many benefits and cost savings. With your CTS system, you can create a digital image on the screen. Next, the operator controls automatic screen exposure and development with a digital touch screen on the lumenator. To expose and develop the screen, the operator places it on the conveyor of the lumenator, selects the appropriate exposure setting from the memory of the controller, and presses the start button.
The entire process, including transport of the screen, exposure and development, is done without any further operator involvement. The operator then saves the autonomous process in the lumenator and can directly take care of the preparation of the next template. The screen is exposed and developed within a maximum of 3-4 minutes. Regardless of the person who performs the task, Lumenator II accelerates stencil production and increases productivity. Depending on the copy layer used, up to 200 screens per 8-hour shift can be produced automatically. The exposure LEDs and the water supply are automatically switched off after completion of the exposure and development.
