Troubleshooting - Candling

In a market where time, speed and cost play the controlling factors, problems will always occur. A prime example of this is the age old issue of "Candling".

Candling takes place almost exclusively with UV varnishes and results in the coating flaking off when rubbed or scratched. It can be a common issue found within Trade or Finishing Houses. The problem is focused primarily over heavy areas of ink or sometimes even specialist inks such as metallics. Generally conventional inks are printed and then sealed with either a Waterbased coating or over print varnish. Once sealed the inks drying time increases considerably and any solvents or distillates within the inks are trapped under the coating film. If the same printed sheet is then subsequently UV varnished to quickly the heat from both the UV lamps and exothermic reaction forces the solvents out breaking the bond between the UV varnishes and underlying ink. The end result is a soft and easily removed UV varnish. If scratched by the fingernail both the varnish and underlying wet ink can be seen.

To overcome such an issue prevention is the by far the best cure and will save time and money. Try to ensure the inks used are of the highest strength to retain a low film weight, this is not always possible if varnishing via a Trade Finisher. If, prior to UV varnishing the sheets were coated allow a minimum of 24 hours for the sheets to dry and if possible ensure stack temperatures are kept to a minimum. Also ensuring the stacks are not wrapped will help, and if they can be turned, even better.

If however the problem occurs the only solution is to leave the varnished sheets to fully dry. Depending upon the print design the drying time could increase to as much as 7 days.
