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.
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.
