Advantages Of Pigment Printing

  2. A wide range of colors could be produced.
  3. Can use in dope dyeing for filament yarn.
  4. Easily applicable.
  5. Less expensive.
  6. Maximum output of goods.
  7. Quick sampling.
  8. High printing speed.

  10. Unsurpassed fastness to light and good general fastness properties.
  11. Extremely well suited for color resist effects.

Disadvantages Of Pigment Printing

  1. Not controllable for the binder film
  2. The use of solvents like kerosene, spirit, etc can produce problems like flammability, odor, pollution, etc.
  3. The jamming up of equipment and air and water pollution is observed.
  4. Wet and rubbing fastness is average
  5. The handle of the printed goods is often unduly hard because of the large amounts of external crosslinking agents.
  6. Are sensitive to crushing during roller printing and pigment printing needs shallow engravings on screen printing
  7. The original surface of the textile material is covered by the binder film. This is occasionally aesthetically effective but usually undesirable.
