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)
