Heat transfer and heat sensitive label printing labeling

Label printing and labeling Machines Most professional and industrial label printing and labeling machines allow you to choose between two thermal printing label printing methods: thermal transfer and thermal sensitive. Which approach should you choose for your business application? # Hashtag #

Heat transfer and heat sensitive label printing labeling

Difference between thermal transfer printing and thermal label printing

First, let’s talk about the similarities: both label printing methods require a heat-sensitive print head that applies heat to the surface being marked. The print head consists of tiny heating elements (dots) that heat a selected area to produce the desired print image. Therefore, the rather generic term thermal printing can be used for direct thermal label printing labeling machines as well as thermal transfer printing labeling machines. Their print resolution is determined by the size, number, and arrangement of the heating elements, measured in points per inch (DPI). Usually 203, 300, or 600 dpi. The higher the number, the higher the resolution and quality of the print.

The practical difference between the two methods lies in the surface that the print head heats: heat transfer printing uses a wax – or resin-based ribbon that transfers the ink to the label when heated. Direct thermal printing, on the other hand, uses thermal labels that turn black when heated directly.

What is the working principle of heat transfer printing?

In heat transfer printing, the heating element of the print head applies point-like heat to the passing ribbon, melting it onto the label and forming a printed image. The label absorbs the ink, making it part of the medium. Ribbon and label materials (materials and adhesives) must be carefully matched to each other and to the specific application for optimum quality and durability.

How does thermal label printing work?

In direct thermal printing, the heating element of the print head heats the label directly as it passes through, and the label has a thermal coating. A chemical reaction causes the label color to change from white to black.

Heat transfer printing and direct heat sensitive printing for label printing – comparison

Thermal label prints are often well suited for the production of bar code labels because they can create high-quality images with excellent edge sharpness, which is necessary for a bar code scanner to successfully capture data. For more information on this topic, check out our six tips for improving bar code quality and a quick guide on how to check bar codes without using a scanner.

We would also like to add that you can print linear and two-dimensional bar codes, such as data matrix codes or TWO-DIMENSIONAL codes, using thermal printing methods. The same goes for text and graphics, of course.
