Strange CTC System ScreenSetter is the crystallization of highly sophisticated optical components, modern electronic sensing mechanisms and the latest drive technology and machining technology.
The heart of this system is an optical MEMS (micro-motor system), a series of digital optical switches based on semiconductors that precisely control the light source, allowing digital images to be accurately projected onto a pre-coated screen plate.
According to Odyssey, this system has great advantages in terms of workflow and image quality. The output resolution is 900 to 2500 dpi, which is impossible to achieve with other imaging technologies. It is particularly suitable for applications on hard materials. , such as CD printing, film switches, and other high-resolution printing applications.
Operating principle
Ordinary screen stencils or UV sensitized materials are exposed directly from digital image data. In the process, UV light hits a digital micro-mirror device (DMD) consisting of nearly 1 million micro-mirrors, each of which The mirror can be digitally controlled, or receive light projected through the optical lens system, or deflect the light so that the lens does not hit the light. This means that the mirror looks like an image carrier and produces a screen image on the template. A limited number of microscopic mirrors means that only a part of the image can be projected. These images are arranged in a size of about 0.8 to 6.3 cm2. The storage depends on the selected resolution. They are connected together to form a combined pattern and then exposed. .
Imaging device
The entire captured image device includes a UV light source and a lens system. The DLP chip moves laterally through the stencil so that the elements of the image are transverse to the stencil. The exact distance between the lens and the surface of the screen stencil is continuously measured by the laser. When the distance deviates from the set value, it can be automatically corrected to ensure that the distance between the exposure head and the stencil is consistent and adjusted according to the unevenness of the stencil.
Transmission mechanism
The transmission mechanism of precision machining is composed of modern electronics and powerful software. The combination of linear motor and electronic control device ensures the fastest positioning speed and the accuracy of seamless image connection is up to 2μ. It is operated by computer display screen, keyboard and mouse.
The first system of this system had been assembled before last year's SGIA 2000 exhibition. The system's format was 50cm × 70cm to 140cm × 180cm, and there were other web systems afterwards.
The advantages of this system over other CTC systems are: further reduction in the production process of screen printing plates; direct UV exposure without screen sizing to ensure optimal image quality; reliable exposure and precise positioning of images on the stencil The system's monitoring time and post-exposure inspection time; shortened the time taken from imaging to debugging of the printing and printing presses.
No need for consumables - No need for covering materials, such as inkjet inks or waxes, no special photopolymer adhesives are required.
Resolution and Image Quality - ScreenSetter's rugged, precision actuators and specially developed lens mounts enable resolutions up to 2 500 dpi with advanced cooling to prevent dimensional changes due to heat from UV light sources. Achieve the resolution that cannot be achieved by ordinary CTS systems.
Higher system stability - Since the CTC system is an integrated device that fully digitizes the prepress workflow, there is no need to eject liquid through the micro-holes, and no filters or chemicals can cause clogging.
Lower operating costs - The light source is an ordinary 500W metal halide UV lamp that is easily replaceable by the operator and is environmentally friendly.
