Due to the continuous changes in application technology, ever faster running machines and alcohol-free printing, printing inks, printing plates and printing press types must be well coordinated.
In view of the large variety of print media, colours, dampening unit types and other printing conditions, a differentiation in the fountain solution additives is crucial for a trouble-free printing process. Machine, ink, water, paper, temperature and the legal requirements have a great influence on the printing processes and thus on the dampening solution concentrate.
DC DruckChemie provides every machine type and the associated dampening system with the ideal dampening solution with which the quality standards are met - while minimizing it at the same time of paper waste. Our dampening solutions are certified with regard to their corrosion behaviour and are available in all common quantities - from the 10 kg canister to the 200 kg barrel and the 1,000 kg IBC.
We guarantee a consistent pH of the damping circulation by use of our fount solutions when the following advantages typographically arise:
• No negative build-up of the colour on the non-printing areas of the printing blanket
• Eliminate corrosion of plates, blankets and printing cylinders
• No dot gain
• Optimal free running of the plates
All dampening solutions of the NP series are characterized by a high buffer capacity and a stable pH value in the pressure-favourable range and also ensure optimal surface tension, fast free-running and therefore less waste. The fountain solutions of the NP series allow a short water flow and prevent over-emulsification of the ink.
Corrosion approvals for MAN and KBA demonstrate the excellent corrosion protection properties of our dampening solution concentrates, which are available for all types of dampening units.

Due to continual changes in inks or ink formulations, a release of fillers, such as chalk from the ink or kaolin from the paper often takes place. This results in washouts and deposits in the dampening water system and on the rollers. Our specially developed heatset fount solutions prevent the occurrence of these print process-hindering and time consuming effects.

Our dampening additive concentrates for sheet-fed offset can be used for all substrates and, even with an extremely low dosing (2 to 3%), they prevent roller glazing and ink stripping, thereby guaranteeing optimal plate protection. An over emulsifying of the ink is prevented and a stable ink-water balance is produced so that a problem-free print run is possible.

Fountain solution additives
DC offers various hardening agents based on calcium or magnesium which, in customer-specific dosing, keep the process water constant between 9 ° and 12 ° dH (German hardness) and facilitate the printing process with this optimal water hardness.
Additive for heatset printing and offers printers both economic and ecological advantages. With minimal effort, the number of cleaning cycles during a print job can be almost halved.
