6. There are some key differences between thermal and thermal transfer printheads: .......Thermal printing: .......How it works: Thermal printing uses chemically treated thermal media. As the media passes under the thermal print head, it turns black, printing the desired pattern on the label. .......No ink or ribbon required: Thermal label printers do not require the use of ink, toner or ribbon, so the cost of use is relatively low. .......Applicability: Suitable for some short-life cycle applications such as labeling meat and dairy products, as well as patient wristbands and drug prescriptions. .......Thermal transfer printing: .......Working principle: Thermal transfer printing heats the ribbon to melt the ink on the label material to form a pattern. .......Ribbon Cost: Although thermal transfer printers require the use of ribbons, they provide a more durable image. The cost of ribbons is relatively high. .......Suitability: Suitable for barcode label applications requiring high quality, accurate images and good edge definition. .......Other considerations: .......Printhead life: Thermal printheads are in direct contact with labels, so their lifespan is usually shorter than thermal transfer printheads. .......Label durability: Choose the appropriate label type based on the operating environment. Thermal transfer labels are more resistant to heat, light and abrasion and are suitable for long-term use. Thermal labels are typically used in short life cycle applications. |
