WHAT IS THERMAL TRANSFER PRINTING?
A Thermal Transfer Printer is an electronic device for printing text date, batch and price code changes, real time coding, barcodes and/or graphics on to a wide range of substrates.
HOW DOES THERMAL TRANSFER WORK?
At the core of a Thermal Transfer Printer is an electronic print head containing an array of tiny heating elements. The print head elements generate enough heat to release pigment from an coated ribbon, which is then pressed on to the substrate to create an image.
The printer is ideal for installing onto most forms of packaging and labelling machinery and is used in a wide range of market sectors including food, pharmaceutical, electronics and automotive, in fact wherever variable or fixed printed information is required.
INTERMITTENT MOTION THERMAL TRANSFER PRINTERS
The most common application for an on-line thermal transfer printer is to print or code on to a web, label or other item that is stationary. This is referred to as intermittent. They are suited to packaging, labelling and other machinery where the web material or item to be printed stops once per machine cycle. Intermittent printers print during this stop time.
CONTINUOUS MOTION THERMAL TRANSFER PRINTERS
On some parent machines continuous printing is required as the substrate is always moving. On a flow wrapper for example, the film moves continuously while the machine is operating. To allow for this it is necessary to fit a printer that has been adapted to print on to a continuously moving substrate.
Continuous Thermocodes use an encoder device to measure the speed at which the substrate is moving. The printer then uses this information to calculate how fast to lay down the print image and to feed the thermal ribbon. This ensures consistency of print quality and position irrespective of whether the substrate is accelerating from start up, decelerating to a stop or running at a constant speed.
