PRINT RESOLUTION
One of the key elements in bar code printing is the print resolution of the printer. Print resolution is measured in dots per inch (dpi). The higher the resolution the better the print quality of the label. Most commonly used resolution are 200, 300 and 400 dpi.
DIFFERENCE BETWEEN DIRECT THERMAL AND THERMAL TRANSFER
Direct thermal and thermal transfer differ in a number of ways:
1. Thermal transfer must use a ribbon to form an image. Direct thermal uses media with a pre-applied heat sensitive coating;
2. Thermal transfer can print in a variety of colors via colored ribbons. Direct thermal is largely limited to limit colour imaging;
3. Thermal transfer images are more resistant to light and chemical than direct thermal images;
4. Thermal transfer media is less expensive than direct thermal media, however thermal transfer requires the use of ribbons.
RIBBONS
There are three primary types of ribbons available for thermal transfer printers, the use of which is dependent upon the type of media being used:
1. Wax Ribbons;
2. Wax/Resin combination ribbons;
3. Resin Ribbons.
