There is a lot of talk about whether direct thermal or thermal transfer
printing is the better choice for your tags and labels. You may get
different answers depending on who you speak with. However, it really
depends on your individual needs.
Direct
thermal printing involves the direct application of the heated print
head to a specially treated paper. Once the heat is applied, the image
is then burned directly onto the paper. Many people prefer direct
thermal printing because it does not use ribbons. On the other hand,
the special type of paper that is used is not very durable and does not
last long. It is similar to fax paper. Over time the paper will fade
and start to discolor. Direct thermal printing is best for short term
use, like shipping and packaging labels.
On the other hand there is thermal transfer printing. This type of
printing requires a ribbon. In thermal transfer printers, the heat of
the print head transfers the image through the wax and/or resin ribbon
to your label. As opposed to direct thermal printing, the image on your
label or tag will last for years. If your label is going to be exposed
to the outdoors or constantly changing elements, thermal transfer
printing is the way to go.
Quick Reference to Choose the Right Method:
Direct Thermal Printing Is Best for:
-labels needed for short term use
-you want to print without using a ribbon
Thermal Transfer Printing Is Best for:
-labels that need to be durable
-labels that will be exposed to outdoors and/or changing conditions
-labels needed for long-term use
