The market generally has 3 types printer, thermal transfer printing, inkjet, and laser. These 3 types have obvious differences in applicable materials, printing speed, resolution, durability and application fields. Choosing the right coding method depends on specific needs, including coding surface material, coding quality and production efficiency, etc.
The thermal transfer machine has the lowest cost, its consumables are carbon ribbons which are not expensive and can be bought all over the world. They can print large-area content such as LOGO, form, characters, QR codes, barcodes, etc., with high resolution, and basically no maintenance, But the long-lasting effect of its printed content is average, only suitable for contact type printing on the flat surface of the composite film.
Inkjet printer suitable for a variety of materials, composite film, carton, metal, plastic, non-contact inkjet code, with high-speed assembly lines can spray two-dimensional code bar code, but need to be in a nozzle height of generally 12mm, if it is with intermittent machine, printing two-dimensional code bar code recognition rate is not high, can only spray characters., the consumables are Ink and thinner or ink cartridges cost a lot. Generally, there is a chip password. Only ink or ink cartridges of its brand can be used. The nozzle needs to be cleaned in time, and the daily maintenance cost is high.
Laser machines are basically suitable for all types of product surfaces, including metal, plastic, and ceramics. There is no damage to the product surface. The cost of purchasing the machine is high in the early stage, but it only needs to be powered on, no consumables, no pollution, long service life, and basically no maintenance. The logo is carved by laser, permanent and effective, suitable for products with high anti-counterfeiting and anti-tampering or traceability., such as high-end consumer goods, electronic equipment, etc.
