Tube Cooling Minimises Substrate Heat
Using cooling tubes on lampheads for drying ink between the applications of different colours offers a major advantage in that the heat on the substrate is minimised.

Primarc Shows Latest UV Lamps at Drupa 2004
UV curing lamp manufacturer Primarc UV Technology will be showing its recently expanded series of spectrally enhanced metal halide UV lamps at Drupa 2004.
The use of cooling tubes is particularly valuable therefore when printing on heat sensitive and lightweight substrates such as plastic, foil and film.
The tubes also filter out infra-red radiation, ensuring that the machine never gets too hot or damaged by heat.
Cooling tubes from Primarc are designed for both water and air-cooled systems.
Normally, they are mounted between the UV lamp and the substrate.
Cooling tubes do need to be kept clean to maximise performance.
Keeping the tubes clean can be relatively straightforward, as there is normally no air extraction over the tubes to introduce contamination.
The tubes can be maintained in peak condition by occasionally cleaning with a soft cotton cloth doped with iso-propanol.
In order to maintain the purity of the tubes, only deionised water should be used in water-filtered systems.
