Printer Imaging
The main technology used throughout the Auto Identification and Data Collection industry (AIDC) is provided by thermal printers. There are two basic methodologies used by thermal printhead technology printers: Direct Thermal (DT) and Thermal Transfer (TT).
What is Direct Thermal (DT) Printing?
Direct thermal printing creates an image or marks the printable media by the use of small controlled heat sections on the thermal printhead. Heat alone is the active agent in this type of printing. Specially coated and thermally sensitive media reacts to the direct heat and the paper darkens at fine spaces where this reaction occurs between the paper’s coating and the printhead.
Advantages |
Disadvantages |
No ribbon required |
Limited number of available types of media |
Lower operational cost |
Highly sensitive to heat, light, abrasion |
|
Short media shelf life |
|
Limited image quality |
Direct Thermal printing includes applications such as:
- Mobile Applications
- Shelf Marking
- Price Change or Promotional Marking

What is Thermal Transfer (TT) Printing?
Thermal Transfer printing creates an image by melting a coating of wax or resin of a specially inked ribbon onto media as the media passes under the printhead. At each of these fine spaces the ribbon’s ink stays glued (or ‘ironed’) onto the media surface and as such is ‘Thermally Transferred’ from the ribbon to the media. Using this method, the ribbon material reacts to the direct heat of printhead elements and the media darkens to the degree that the ribbon’s ink is burned onto the printable surface.
Wax ribbons are best for general purpose labeling.
Wax/resin ribbons are a good choice for moderate scratch, abrasion and mild chemical resistance. Resin ribbons provide the best performance in harsh environmental conditions.
Advantages |
Disadvantages |
Requires 1 to 2 years media shelf life |
Special ribbons required |
Media is not heat sensitive |
Average operational cost |
Medium to high image quality |
Cannot print on multiple-copy paper |
Wide range of available types |
Single-pass ribbons only |
Industrial thermal transfer printing includes applications such as:
- Industrial Printing Applications
- Decal
