Sheet offset Drying

Ink drying

Speed, quality and productivity are decisive in the graphics industry. The standard inks need a certain drying time which limit the production speed.

By using infrared dry systems in combination with, the for this purpose special developed inks, the drying time will be reduced.

Advantages of Infrared drying

  • Quick setting and drying
  • No second impression
  • Maximum stacking height, so reduced space requirements
  • Reprinting and finishing as soon as within 30 minutes
  • Powder savings of 60 – 100%, resulting
  • Cleaner working environment and lower machine maintenance
  • Density measured wet and dry almost the same
  • Higher gloss values
  • Less dot enlargement
  • Absolute harmless to health

IR dry systems from Jac. de Vries Infraroodtechniek only require little room so they can be placed in the delivery of almost every sheet offset press (see our reference list).

Advantages of Infrared Dryers from Jac. de Vries

  • Standard delivered with short wave IR emitters which an be used on full capacity directly after the have been switched on;
  • Directly cooled down after switching off, so less risk of fire;
  • Integrated air-cooling with optimal protection against overheating;
  • Stepless power control of the IR emitters (hand setting or automatic by measuring the pile temperature);
  • Average lifetime of the IR emitters is about 5000 burning hours;
  • By placing the IR emitters in the length of the paper direction, you are able to set the drying width of the IR panel to the same size as your sheet width (energy efficient);
  • Easy and simply to control
  • Easy change of parts which are all hold in stock;
  • solid and compact construction.
