IR's ability to work evenly over a large surface – and its high level of controllability – make it well-suited for uses like these:
Popular uses for infrared heat in printing applications include:
- CIR Optimizes the Performance of High Speed Printing
- Carbon Infrared Improves Drying of Specialty Papers
- Hybrid Carbon Infrared Heaters Optimize the Drying of Paper Tissues
- Infrared Helps Improve Quality and Productivity of Flexographic printing
- Further Labeling, Printing and Converting
The Alito Color Group of Leyton, London, retrofitted Heraeus carbon infrared (CIR) emitters in place of a short wave near infrared (NIR) print drying system. Now they are able to realise the full potential of its high speed print heads, by increasing sheet feed speeds to match the print speeds with no detriment to print quality. In addition the new emitters use less power than the previous system and offer a significant increase in operating life. This improved energy efficiency impacts far less on the environment.
By installing a Heraeus Carbon Infrared (CIR) system, a manufacturer of specialty papers has enjoyed significant gains in productivity, by ensuring that the important lacquer drying stage no longer adversely affects machine speeds. At the same time, the speed of response of the CIR system means that there is minimal danger of heat damage to sensitive substrates in the event of unexpected stoppage of the production line.
Paper serviettes are popular because they have good absorbency and can be attractively printed. However, during printing, these very properties cause particular problems, as both the ink on the surface and that fraction within the deeper serviette layers must be dried. Only when the ink and water are completely dried can the serviettes be packed. In order to achieve this in-line and in an acceptable time, the drying must be especially efficient.
Short wave and carbon infrared (CIR) emitters from Heraeus Noblelight are helping Zebra Technologies Europe of Preston to improve the productivity of their custom-built flexographic printing presses and the quality of the finished printed products. The emitters have also proved to have an extensive, reliable and consistent working life, which has provided further operating cost savings.
- A printing operation needed a fast, efficient means of drying paper. Their previous method -- offset printing with drying by more than 1000 halogen lamps -- was too expensive. They switched to flexo printing with a modular drying system from Heraeus Noblelight. The Heraeus system reduced the number of lamps needed by nearly 90%. Production speed increased, control increased, and costs fell dramatically.
- A laboratory operation uses microscope slides and biopsy cassettes. These require labeling prior to being archived. Traditionally, this has been done using relatively unreliable methods such as sticky-notes and handwriting. A manufacturer of non-contact inkjet printers developed a way to label these critical items. Heraeus infrared technology is used to dry the inks quickly and evenly.
- A manufacturer of personalized printed communications uses Heraeus infrared technology to dry inks after printing on a six-color printer. The systems -- featuring carbon infrared lamps from Heraeus Noblelight -- includes a control panel for quick switching on/off of the system as needed. Operating costs are much lower, and production time is greatly reduced.
- A manufacturer of high-end wallpaper products replaced its hot air system with infrared from Heraeus Noblelight. The new system dries water-based print on the wallpaper, and allows several types of paper to be dried using a single system. Line speed increased 50% due to high power density at the right wavelength.
- The manufacturer of digital inkjet printing equipment for business and industrial applications sought a means to speed the printing process, in hopes of facilitating truly in-demand printing. The current process used hot air to dry ink/toner onto paper, causing a bottleneck in process time. The company approached Heraeus Noblelight for a faster, more efficient drying method. Heraeus application engineers provided a system that uses Heraeus's proven carbon twin-tube heater. The lamp provided even drying across the paper surfaces, and did so in reduced time.
- A user of high-speed printing presses employing flexography required a fast, thorough, efficient and cost-effective method of drying the water-based inks during the process. The company worked closely with the application experts at Heraeus Noblelight and found that carbon infrared lamp technology is an excellent solution for applications that use water and paper. Carbon infrared lamps provide the heat, and ambient room air carries the remaining vapor away from the paper. No hot air is required for the system.
- A specialty print operation uses inkjet printers for high-speed quick-turnaround print projects for its clients. Prior to stacking and folding, the ink must be dried completely to prevent blurring and other degradation of the printed matter. A custom infrared system from Heraeus Noblelight uses specific IR lamps matched to the needs of the print system. Once it was installed, bottlenecks were eliminated and the overall process now enjoys faster throughput and more consistent quality
