Thermal transfer printing excels
Labels can be printed using several differing printing technologies. However, one of the most popular methods is called thermal transfer printing which uses roll-form labels and printing ribbons. This technology requires lower heat settings to transfer a printed image than some printing methods such as a laser toner process. For this reason, you have the widest variety of paper and film label materials at your disposal, including an extensive choice of label adhesives to fit special labeling applications.
Finding the right printing ribbon
We can’t stress enough how important it is to choose the right thermal transfer ribbon formula for your labels and the right format for your label printer. The bond achieved with a well-matched printing ribbon to a label substrate is critical. With the right ribbon and printer settings, you get the best print quality and durability, sometimes even avoiding the need for a protective film laminate.
Unlike many suppliers, Electronic Imaging Materials, Inc. doesn’t handle just one line of ribbons. Instead, we have a thorough cross-section of high quality ribbons made by some of the most trusted companies in the ribbon industry. We also thoroughly test every ribbon and label material we sell to assure the highest compatibility and durability.
While the ribbons that we offer on our Web Store are formatted to fit the Zebra and TSC printers we sell, we also have ribbons for other popular printer models including Datamax, Intermec, Monarch, Sato and many others.
The Right Formula
Thermal transfer ribbons are classified in three categories: Wax, Wax/Resin and Resin. If you think of them in that order, they basically match the three general classifications for label materials: paper, mid-range, somewhat soft synthetics and glossy, hard films like polyester. Within the three ribbon categories, ribbon manufacturers offer an extensive choice of ribbon formulas to fine-tune print results on specific materials. Not only do they address smudge and scratch resistance, but many handle specific conditions involving chemicals, solvents, and temperature extremes. Initially designed for bar code printing, black thermal transfer ribbons predominate. For label impact, color coding and attracitve graphics, some manufacturers have also developed a good selection of colored printing ribbons based on Process CMYK and spot colors.

The Right Format
With the popularity of variable printing and the need for durable labels, the number of thermal transfer printer manufacturers has grown as have the number of printer models. They range from small desktop units to heavy-duty industrial systems. Fortunately, the mechanisms that drive the printing media are somewhat consistent. They all require a printing ribbon wound on a core, with 1″ and 3″ diameter cores being the most popular sizes. To make their printers more unique, some manufacturers deliberately designed their printers to use unique core sizes. Some require extra take-up cores, while others have special notches to lock the cores into their printers correctly. Ribbons are usually wound on cardboard cores, but plastic ones are also available which are especially useful in clean room environments. Some printers require specific leader strips to feed into the printer while others have special trailers at the end of a roll to alert a printer’s sensors that you are about to run out of ribbon. Some ribbons are wound Coated Side Out (aka face out) while some are wound Coated Side In (aka face in) to properly feed through a printer. The choices can be confusing and overwhelming!
