Direct Thermal Vs Thermal Transfer Printing

Direct thermal printing makes use of label cloth with a heat sensitive coating. When heated through the print head of your printer, the thermal coating turns black to create the picture/text required.

Thermal switch printing makes use of a thermal transfer ribbon (i.E. An ink ribbon additionally known as a carbon ribbon). The print head heats the ribbon and ink is deposited onto the label cloth to create the photo/text required.

Some small computer printers which includes the Zebra GC420d are direct thermal best, but maximum thermal printers will perform in thermal switch or direct thermal mode. The value of consumables is similar for the two strategies of printing. Direct thermal labels are commonly a little extra pricey, but when you add the cost of thermal switch labels and ribbons collectively, the costs are comparable.

The benefits and disadvantages of the two techniques of printing are as follows:

Direct Thermal Printing

Advantages of Direct Thermal Printing:

• Simpler for the operator to load the media (you best have to load the roll of labels).
• It can be less difficult to obtain a very good print best at some stage in the preliminary setup (you do now not need to healthy the ribbon kind to the label fabric).
• Environmentally higher as you do no longer have to remove used ink ribbons (typically you could best use thermal ribbons once).

Disadvantages of Direct Thermal Printing:

• The print will fade in time, specifically if uncovered to direct sunlight.
• The label material will discolour in time, particularly if uncovered to direct daylight.
• The label fabric is prone to marking if rubbed or scuffed.
• Cannot be used in excessive temperature packages (commonly precise to 50°C), as the labels will speedy turn black.
• There is a confined range of direct thermal label materials, in comparison to thermal transfer (although it is viable to reap direct thermal card tag material and some synthetic materials including polypropylene
