TTO Technology
What is TTO printer?
Thermal Transfer Overprinting (TTO) is a technology that creates messages in resolutions up to 300dpi by pushing a ribbon into contact with a substrate using a printhead.
- Backcoat – special layer that protects the printhead against abrasion. It ensures the slippage of ribbon under the printhead
- PET film – as a carrier for thermal transfer ribbon
- Primer – facilitates the application of ink onto the polyester carrier and its transfer onto the label during the printing process
- Ink – there are wax, wax/resin and resin inks available
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.
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.
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.
Application
TTO is widely used in many fields of industrial printing, product identification, order printing, industrial printing, marking, etc., mainly to print a variety of variable information, including name information, numbers, text, serial numbers, color images, etc.
