Contiweb Digital Fluid Applicator


The Contiweb Digital Fluid Applicator (DFA) is a standalone remoistening applicator for digital web presses, developed to significantly improve the quality of digitally printed products.

Based on the popular Contiweb Fluid Applicator for heat set web offset applications, the DFA is an innovative and user-friendly system, which uses tap water and a surfactant to intelligently and very precisely remoisten the paper. Each side of the paper can be individually controlled. Silicone can also be added as an option, decidedly advantageous if inline finishing is being employed. This provides companies with greater remoistening control, ensuring that the final product regains moisture and does not distort from absorbing it from the environment.

Remoistening

Remoistening overcomes common quality issues such as growth of cut books, where the pages do not line up with the cover, page turn-over of short grain books, where the spine of the booklet creases, or page curling. Silicone application is used for protecting the printed material in case of inline finishing.

The principle of the DFA is mixing water and surfactant directly in the applicator trays immediately before it is applied to the printed web. This ensures uniform remoistening and reproducible results. The DFA remoistening system ‘drinks from the tap’, osmose water or DI water is not required. All functions are available in a contained unit, installation and commissioning are based upon a plug and play principle.

Advantages

  • Best homogeneity and uniformity
  • Reproducible results
  • ‘Drinks from the tap’, No osmose water and no additives required
  • Remoistening function possible on all types of paper
  • Cost of Operation = replacement sleeves only

Blog: four common problems after drying in web inkjet

There are four problems that often arise after drying a digitally printed substrate. The high temperatures generated during drying result in the loss of moisture and invariably, the printed matter diminishes in quality. We wrote a blog about those issues and, more importantly, explore what can be done to resolve them.

Case Study Printforce

As inkjet print quality just gets better and better, the quality of final products can suffer from the increased temperatures in the process with substrates drying out and behaving badly. Curling and waviness are examples of problems that often arise.

This case study shows how the installation of a Contiweb Digital Fluid Applicator helped Printforce to resolve these problems and to meet the high quality standards their customers demand.
