A comprehensive overview of current barcode label printing technologies.

Direct thermal printing (Thermal printing).

Direct thermal printing is a professional printing process that uses only a thermal-sensitive label and does not use ink or ribbon. Direct thermal labels fade over time (approximately one year) and are not a good option for high-temperature environments or direct sunlight exposure. With  this barcode label printing technology  , you don't need to buy toner cartridges or ribbon, making it the most cost-effective method.

Indirect thermal printing (Transfer printing/Heat transfer printing).

Indirect thermal printing  is a thermal transfer printing method that applies heat from the print head to an ink ribbon where one side is coated with wax or resin ink. The heat melts the ink coating and transfers it to the label paper. Indirect thermal printing is widely used in indoor barcode printing applications.  This barcode printing method  is an improvement over direct thermal printing in many ways. It offers greater versatility with various paper and composite materials, and can print both black and multi-color ribbons. The print quality is high, and the images are long-lasting and durable.

Inkjet printing technology.

Inkjet barcode printing technology uses tiny droplets of ink delivered through a print head to facilitate direct printing without the need for printing plates in contact with the printing surface. The print head moves continuously on a conveyor belt until the image printing process is complete.
Inkjet printers have the advantage of saving energy and not requiring large print volumes; they can print completely different designs with high color resolution up to 1800 DPI. However, this printing method consumes more ink than other printing techniques, so it is only suitable for small-scale production needs. Inkjet
paper is specially designed for inkjet printers and can usually be identified by its weight, brightness, smoothness, and opacity. Standard inkjet printing requires paper with sufficient water absorption to capture the ink but to prevent the spread of the ink solvent (and therefore, the inkjet ink) on the surface and within the paper.

Laser printing technology.

Laser printers are widely used by many companies and stores to print barcode labels on pre-cut A4 or A5 size decal paper due to their availability, convenience, and low cost. However, laser printers are difficult to use for labels with adhesive backing because the high temperature will melt the adhesive and cause it to peel off the label. Despite these drawbacks, laser printers are still chosen by many businesses because of the quality of the product they deliver.

All types of machines have their own advantages and disadvantages. Depending on the scale and type of business or production, enterprises can choose a suitable machine for their needs.
