Further Details:

The diazo products of Asian, distinguish themselves by a high standard of quality and are oriented to comprehensively fulfill the multiple demands of the user.

The use of selected, high grade raw materials, ISO-conforming manufacturing processes and our well trained, experienced and motivated staff, all guarantee for the high quality of our products. Our diazo papers are extra white, opaque and mechanically tear resistant. They permit excellent copying results with high-contrast image lines. The photo sensitive coatings permit good copying speeds and high coverage, very light resistant and document consistent image lines.

Image Colours

Diazo papers are available in blue line and black line. The blue line papers are usually selected for general copying, for reproducing drawings, typed or printed business forms, etc. Black line papers are used for office copying, correspondence, forms etc. It is also used as profile in textile industries.

Process

The principle of diazo copying is based on trans illumination.  A written or drawn original is placed on the light sensitive diazo paper or film and is illuminated. In so doing, the light passes through the document onto the diazo paper and reduces the photosensitive layer there, with exception of those place on the document which are covered by drawing text or text. These places are then converted into dye by the subsequent development and thus yield a true image of the original.

Specification

• The speed of Exposure should be maintained according to the clarity of the master tracing and the quality of the Diazo on the base paper.
  
• The developing time with liquid ammonia should be decided with a small print, before going for mass  production.
  
• Always use a voltage stabilizer for the printing  machine to ensure uniform light emission.
