SCHWEGO® soft 1000 AWT / ANT

Fountain additives for sheetfed offset for IPA-free printing, with drying accelerator
Technical data sheet

Function: SCHWEGO soft 1000 AWT/ANT are fountain additives with drying accelerant for sheetfed offset printing; they ensure a printing process without any additional isopropanol (IPA) in the fountain water.

Even without IPA a static and dynamic surface tension is reached in the application concentration which usually is only to be found with a concentration of about 10 % IPA. In addition, an increase of viscosity will favour the water transport to the printing plate.

SCHWEGO soft 1000 AWT for water hardness up to 12° KH
SCHWEGO soft 1000 ANT for water hardness from 12° KH
Properties:
  • Accelerated surface drying of the printing ink
  • Stable ink-water emulsion, especially with special colours
  • Complexing of the hardness formers prevents deposits on the ink and damping rollers
  • Stable adjustment of the pH-value
  • Fast free running behaviour
  • Special wetting agents will produce an even fountain water film
  • Suitable for CtP-plates
  • Also suitable for UV- and hybrid printing inks
  • Fastened surface drying of the printing ink
  • Checked and released according to the default settings of the leading machine-builders
Tip: The condition of successful printing without IPA is instinct and sensitivity of the press operator. The rule for a stable ink-water balance is:„As little water and ink as possible“.

As long as the balance is right, you can reach high ink densities even with reduced ink-water flow.

Subject to appropriate storage, the described properties of SCHWEGO soft 1000 AWT/ANT remain stable for at least 6 months.
Quantity to add: SCHWEGO soft 1000 AWT/ANT is added to the water with a share of about 2-4%.
Packaging: 10/20 kg can · 200 kg drum · 600/1000 kg container
