Inkjet Printing Technologies - brief

1. Flexography - is a form of printing process which utilizes two flexible relief plate.
2. Lithography - no flexible
3. 
   

Inkjet

Continuous Inkjet (CIJ)

 

Amateur technology - 50KHz to 175KHz

Piezo Crystal

Challenges

1. aplication performance (functional)
2. print quality (bleed, surface wetting)
3. compatibility
4. drying/curing time (relating to speed)
5. adhesion
6. jetting characteristics (viscosity, dynamic surface tension, etc.)
7. reability
8. easy of manufacturing
9. regulatory
