Here you will find everything you need to know about thermal transfer printers and direct thermal printers. Thermal transfer printers use a heated print head that moves a wax or resin-coated printing tape. The direct thermal printer produces an image from chemically treated paper with a heat-sensitive coating that turns black on the heated printhead.
In contrast to direct thermal printing, where the ink already embedded in the printing surface is transformed by heat, thermal transfer printing transfers the ink to the paper. The heated print head melts the wax into a specially treated paper or printing material.
The difference between the two is that thermal transfer printing uses a specially developed tape to transfer the image to the label. GHS harmonize is printed with a thermal printer for secondary packaging and pallet labelling. The printer works with both thermal transfers and direct thermal labels, using the same paper and tape as the original thermal label for primary packaging.
Instead, the label darkens the color of the previous material in response to heat and pressure during printing. When exposed to the heat of a thermal printhead, chemically treated label materials such as paper or tape do not darken in the same way.
Although the pressure on direct thermal material contains a chemistry that darkens over the lifetime, the blackout reaction always occurs when the material is exposed to high heat. Leuco - dye is the chemistry that makes this heat reaction possible.
Direct thermal substrates comprise a wide range of materials with different thermal conductivity depending on the surface layer. Direct thermal substrates may contain different types of surface layers such as polymers, polystyrene or polyethylene, which have different thermal properties depending on the surface layer.
Thermal transfer printers are characterised by printing on a wide range of media, including polypropylene, polyester and paper materials. They are ideal for labelling chemical laboratory samples and for producing chemical samples. These printers offer the possibility to print directly thermally on a large number of different materials, making them an ideal choice for use in the field of thermal transfer printing.
This method is ideal for high-density barcodes and can be confidently used for what is called "long-life product labeling." Thermal transfer printing is very crisp and durable, but thermal transfer labels often have to meet high requirements. It is therefore particularly important to choose the right transfer tape that fits the most suitable label warehouse. Direct thermal printers apply heat to a paper that is specially coated with some form of heat - sensitive material on the print head.
When heat is applied, the coating turns black, turns off and turns on, providing an illustration of the color, size, shape, thickness, color and saturation of the label.
Thermal transfer printers therefore use carbon ribbons, the colour that is transferred to the label by heat. The tape sits between the print head and the thermal transfer label and protects both print heads, avoiding any abrasion during printing.
Direct thermal printing can be described as a digital printing process, but also as a special coated paper used for direct thermal printing. For specially coated papers, direct thermal printing is a thermochrome paper film that has special chemicals that are designed to react when the paper film comes into contact with the heat of the thermal printhead. We have seen that direct thermal printing is much more efficient than conventional thermal transfer printing.
The direct thermal label is a pressure sensitive label that has an image that is activated when the label comes into contact with the heat of the thermal printhead when used in a direct thermal printer. Thermal labels can refer to labels that are printed using two processes, which use heat to apply images to a specially treated surface to which they are to be written or written.
There are two types of thermal printing, and direct thermal printers require a special paper or printing material coated with Leuco dye. Direct thermal The print produces sharper print quality when scanning barcodes, but requires a different type of paper and special printing materials such as special ink or special papers with leuCO dye coating.
If you don't need to print address labels or fresh food tickets, direct thermal is the cheapest and easiest method.
A thermal transfer printer uses a printhead that melts ink and ribbons into the label instead of the ink itself. A high-quality thermal transfer printer has a high degree of heat transfer and a low
