Abstract
An apparatus for setting radiation curable ink deposited onto a substrate. The apparatus includes a series of ink jet print heads which deposit ink onto the substrate, and a radiation source mounted laterally adjacent to the series of ink jet print heads. The amount of energy provided by the radiation source is sufficient to cause the radiation curable ink to set.
Claims15
An apparatus, comprising:
- a series of ink jet print heads which deposit radiation curable ink onto a substrate;
- and
- at least one radiation source mounted laterally adjacent to the series of ink jet print heads which deliver a set energy to cause the ink to set to a non-hardened quasi-fluid state, the set energy being about 5% of a cure energy required to frilly cure and harden the ink.
A method for setting ink, comprising:
- depositing the ink onto the substrate with a series of ink jet print heads;
- and
- emitting a set energy from a radiation source that is positioned laterally adjacent to the series of ink jet print heads to cause the ink to set to a non-hardened quasi-fluid state, the set energy being about 5% of a cure energy required to fully cure and harden the ink.
