Photo Emulsion for CTS DLE (DMD)

CTS RT-108 is ready-to-use, fast computer to screen emulsion for textile printing with water-based ink or abrasive print media. Extremely fast exposure approximately 30 times faster than dual-cures like diazo type rotary emulsion. It's fast exposure time enables direct light engraving (DLE) exposure. DLE-W making it suitable for excellent fine detail image.
Fast exposing single cure emulsion.
High viscosity and high solid makes best quality
excellent print performance, direct to use

Exposure Data
To achieve a good stencil, the mesh must be degreased with a degreaser and must be free of dirt, dust, ink residues and ghost images. Rinse the screen thoroughly using low water pressure to remove any degreaser remaining on the screen. A foaming degreaser helps to determine proper and complete rinsing. See MSDS Information for details.
RT-108 has excellent coating properties on mesh counts of 40-470 threads per inch (16-185 threads per cm). Always start with 1 or 2 coats on the substrate side of the screen to fill the mesh openings; then finish with wet-on-wet coats on the squeegee side to build up the emulsion coating to the desired thickness. The correct coating technique for your process must be determined through coating tests.
Dry the screen in complete darkness, or under safe-light conditions,with the screen in horizontal position with the substrate side down.
Temperature, relative humidity and airflow affect the drying time. The screen must be dried thoroughly before exposing to achieve highest resistance to ink and ink cleaners. A temperature of 86°-104°F (30°-40°C) at a relative humidity of 30% -50% and moderate airflow are optimum conditions. Drying at room temperature and in uncontrolled conditions may lead to inconsistent results and varying screen resistance.
Expose with ultra-violet light at a wavelength of 320 - 380 nm. A metal halide lamp provides the best results. Due to the many
variables that determine the actual exposure time, accurate exposure times cannot be given. The following examples are offered as a
guide only:
Lamp: CST CTS DLE engraving machine (DMD technology)
NBC 120T white mesh, coating thickness: 3-5 um.
Expose speed: approximately 19-22CM/Second
The correct exposure time for your equipment and mesh selection must be determined through exposure tests using a step exposure or an exposure calculator films.
