There are two thermal printing methods: direct thermal and thermal transfer. Each method uses a thermal print head that applies heat to the surface being marked. Nearly all of our printer models can do both methods of printing.
Direct thermal printing creates the image directly on the printed materials. Direct thermal media is coated with a heat sensitive coating which blackens under the thermal print head but it is more sensitive to light, heat and abrasion causing fading so this kind of environment exposure should be avoided. This printing method still provides ample lifespan for many common label printing applications such as shipping labels, scale labels, price labels, tickets, visitor passes, patient labels and wristbands, etc.
Thermal transfer printing, a thermal printhead applies heat to a ribbon, which melts ink onto the material to form the images. The ink is absorbed so that the images becomes part of the media. This technique produces durable, long-lasting and the best quality images on a wide variety of printing materials including papers, white films, clear films and it is less susceptible to the external environment.
preprinted template labels rolls
Labels for thermal printing does not necessary have to be blank white, you can have the labels preprinted and decorated with colorful graphics, logos, patterns, slogans, fixed texts such as contact information. You just need to leave out some blank spaces on the labels for overprinting by the label printer. The label printer can overprint variable information such as item names, descriptions, dates, barcodes, batch numbers, serial numbers, addresses etc. on the blank spaces of the labels.
A common use of these preprinted labels is to have just one standard template label and makes many different versions by overprinting the labels with variable information. This saves time, money and removes the need to order and keep so many different versions of label stocks. You can print on demand just as many labels as you needed for any versions.
