‘Infrared emitters for industrial processes’ - .PDF file.

Short-wave and carbon infrared (CIR) emitters from Heraeus Noblelight are helping Zebra Technologies Europe of Preston to improve the productivity of its custom-built flexographic printing presses and the quality of the finished printed products.

Zebra Technologies’ Specialty Printing Group (SPG) designs, manufactures and sells speciality thermal transfer printing devices that print variable information on demand at the point of use, for applications such as hospital wrist bands, self-adhesive labels and customised identification cards.

To supply these printing devices, Zebra pre-prints customised labels and specific printed items at its Preston facility, using its purpose-designed flexographic printing presses.

An important part of the flexographic printing process is the drying of the water-based and UV inks used in the printing presses, which can print up to 10 colours. This must be carried out as efficiently and quickly as possible to meet quality specifications and to achieve optimum productivity.

Having considered warm-air ovens for the water-based inks, Zebra eventually installed CIR and short-wave emitters in line with the printing process.

Key benefits of product application

  • The emitters have proved to have an extensive, reliable and consistent working life, which has provided further operating cost savings.
  • Mark Richmond, project engineer at Zebra, said: ‘The infrared drying system allows us to achieve line speeds of up to 300m/min.’
  • He added: ‘The system’s fast response ensures that there is minimal damage to paper in the system in the event of unexpected shutdown.’
