Thermal Transfer - Ribbons

We are engaged in distributing and supplying of Thermal Transfer - Ribbons in Ludhiana, Punjab, India. The printers use a fixed width thermal print head, pressing onto a paper or plastic label, over a driven rubber roller called a platen. Between the print head and the label is sandwiched a very thin thermal transfer ribbon (or sometimes called "foil"), which is a polyester film which has been coated on the label side with a wax, wax-resin or pure resin "ink". The ribbon is spooled onto reels up to 625 meters (1965 feet) long and is driven through the printing mechanism in sync with the labels, at speeds of up to 12 inches per second (although 6 inches per second is adequate for most applications). A few specialized printers will unload the head pressure and stop advancing the ribbon when there are longer unprinted label areas to be fed through to reduce ribbon consumption, this complexity is only warranted for large volumes applications but can make the ribbon stock run out partway through a label roll whereas normally a ribbon will be finished after an integer number of label rolls.
