It is powder more environment-friendly than others.

Scattering is less than others and it is safe for the body.


  • The main ingredients of powder are using vegetable starch.
  • Since it is made of a safe ingredient even if powder is inhaled accidentally or it goes into a mouth, it can be used in comfort.
  • There is little generating of static electricity and uniform equal spraying is possible.
  • Only uniform grains are carefully selected to prevent blocking and ink set-off at the least amount.
  • Minimize accumulated powder on equipment by less scattering or dispersion.
  • Smoothen the surface of printed sheets
  • Less maintenance for blanket cylinders

ECO POWDER is recommended to use with our powder spraying system CHP-3/ CHP-21 for better results.

By combined use with CHP-3/CHP-21, an average of 50% reduction of the amount of the powder used is possible.

Degree of Relative Scattering of Each Company “Non-Coated Powder”

As the powder is derived from natural starch, the particle size may vary on original of the material and climate changes.
 *1・・・The highest particle diameter of particle size distribution (%)
