Laser Photo Plotter With Up To 25,400 dpi Resolution
Technical data laser photo plotter
- Resolution max. 25,400 dpi
- Positioning accuracy ± 4 µm over the entire plot area of 813 x 711 mm²
- Minimum line width 10 µm
Laser photo plots for fine line printing
A resolution between 16,000 and 25,400 dpi is more than sufficient for manufacturing fine line printing screens with positioning accuracy. Higher resolutions will not increase the quality and are uneconomic.Laser photo plots for special applications
For special applications (for example, angle encoders) we can of course also offer photo plots with a resolution of up to 100,000 dpi and glass masters with 100,000 and 200,000 dpi.Film distortion is minimized by controlled climatic conditions
- 21 °C ± 1 °C
- 50 % ± 5 % relative humidity
Thermal coefficient of expansion of the film material
- 18 µm per °C per 1 m length of film
- 12 µm per % humidity per 1 m length of film
(for a more detailed overview please refer to the table)
