Because the glass surface smooth, hard, its products are transparent, so is suitable for soft touch screen printing method to complete the color printing.Glass is inorganic materials, good chemical stability.Therefore, the glass printing mainly adopts the screen printing method.The following main screen printing process before and after printing, printing technology in China and India should pay attention to the problems and requirements of carries on the discussion and research.

> before printing production operation and matters needing attention

        1, prepress preparation

          Screen printing: glass screen printing screen general purpose use 200-200 mesh, using 300-420 mesh fine pattern

          Printing ink, glass printing ink is made up of colorants mixes with flux, then connected to the wiper plate material made of mix into a paste and stir.

         To seal the glass, glass surface energy is higher, the environmental impact, once the air surface is covered by a layer of adsorbed film soon, make its wettability, and humor adhesive force.So proper surface in front of the screen printing to skim.
