Advantages Disadvantages
No solvent = inflammable Relatively expensive chemicals
Little energy required Monomers/oligomers
Fast drying/curingNo drying untill UV exposed
UV can cause burns - avoid skin contact
High production speeds Ozone generation
Thermosensitive Prints - Coatings (low flexibility)
Little space required Unknown Technology (for most)
Relatively low equipment cost - Less space requirements
- Modular - implementation in excisting coating line
Adhesion problems on some substrates (but canbe solved)
