What is Thermal Transfer Overprint?
Thermal Transfer Overprint (TTO) is a method where heat is used to transfer ink from a Thermal Transfer Ribbon onto a flexible substrate like food, beverage, and medication packaging. This technique is used for example for the printing of barcodes and variable information such as best-by dates and serial numbers.
What makes TTO challenging?
The challenge of printing on flexible packaging on a high-speed production line is to guarantee high-quality printing with compliant variable data on each and every item. TTO is designed to do just that.
TTO printers are in direct contact with the substrate. This ensures the swift transfer of high-quality variable data onto flexible packaging material such as PP, PET, aluminium, paper and Tyvek.
What requirements are there for Thermal Transfer Ribbons?
In-line printing is done at high speeds of 20 IPS and therefore needs specific Thermal Transfer Ribbons that release the ink at high speeds and enable long production runs without unnecessary changeovers.
DNP offers a range of TTO ribbons such as and will be introducing several new ribbons in the year to come. The assortment contains products for general applications and specific requirements.
Our technical experts are available to help you install the ribbons according to your specific requirements. More information on these ribbons is available on our product pages.
