piezo head and Thermal head difference!

what is different between piezo head printer and Thermal head printer!

introduction of piezo head printer:

piezo technology is primarily pressurized by pizeo to special materials , and then use it to shrink the expanded , extruded ink nozzles to spray on the sheet set . Typically, the format piezo inkjet printer to print is relatively large , mainly used for outdoor , print quality is very high , the nozzle is also very durable , long time .

introduction of Thermal head printer:

This technique is the use of the nozzle to heat the metal plate , and the ink is heated and vaporized portion of the ink will produce bubbles cause the ink to the extrusion nozzle , sprayed onto the paper . Such pictorial print format is relatively small, mainly used for indoor , prone to heat when printing nozzle life is short, the print speed is relatively slow , but relatively low prices.

Comparison:

the piezo head printer is more dominant, there are a lot of companies are using piezoelectric head printer , though the piezo inkjet printer more expensive, but also within the acceptable range we Moreover , the pressure electric piezo heads long life, fast print speeds , from a certain extent also saves production costs

inks:

piezo head printer can use many types of ink, such as eco solvent ink for outdoor printing, and also can be used sublimation ink for printing T-shirt, heat transfer.

but Thermal head printer can only use water-based ink and water proof ink, such as ( novajet 750 printer,six color indoor printing machine,all these printer is cheap.)

head life and resulotion:

piezo head can printing more 20000 square meter inks, and resulotion is more than 1440DIP , printing quality is nice more than Thermal heads. 

printed media:

piezo head printer can printing all indoor and outdoor media (PP paper, adhesive paper,vinyls,one way vision,outdoor flex banner, sublimation paper,photo paper,mesh,and all outdoor and indoor meida), but Thermal head can only be used pp paper, adhesive paper,photo paper,canvas,fabirc,PVC )
