Remoistening / conditioning
In digital printing, dryer systems are used to dry water-based inkjet inks or to fix toner-based systems. Paper consists of organic fibers whose properties change negatively when exposed to heat.
The following problems can occur:
Raised edges (curling) and plates of the paper
Wave formation in printed products
Reduced register and register accuracy in further processing
Rough and unclean fold breaks
Reduced processing speed due to high static charges
**Nature needs moisture - so do your printed products !
With the WEKO-DigiCon, the paper can be given back exactly the missing moisture that was previously removed by high drying (performance) temparature.
Using a non-contact rotor spray process, fine micro-droplets are evenly distributed on the paper surface. The paper regains its natural properties. The above-mentioned (impairments) Disadvantages are significantly improved - processing speed and the quality of the end products can be sustainably increased.
