Direct Thermal Direct thermal printers contain a thermal print head that applies heat energy to a specially coated facestock that turns black when heated to create the required images. Direct thermal saves money by not requiring the use of an inking ribbon. However, the coated facestock is more expensive than non-thermally coated facestocks and is very sensitive to temperature, light, water, chemicals and hard use. The life expectancy of direct thermal labels is usually less than one year. Direct thermal labels perform best for short term or indoor uses such as products with short shelf lives, shipping or indoor inventory control. Thermal Transfer Thermal transfer printing is the most widely used method for inhouse bar code label printing. A thermal print head is used to generate heat energy that in turn transfers the ink from a ribbon onto the label facestock, creating the required images. This method improves upon direct thermal printing in several ways. A wide variety of both paper and synthetic facestock materials may be used with both black and colored ribbons. Print quality is very high; the image is long lasting and durable. Bar codes can easily be read by both infrared and visible light reading devices.
