Abstract
A method is disclosed of printing an area of a substrate in a plurality of passes using curable ink, the method comprising depositing a first pass of ink on the area, partially curing ink deposited in the first pass, depositing a second pass of ink on the area, and fully curing the ink on the area. The method finds particular application in the field of inkjet printing, and can afford the advantage of better wetting of ink on the substrate deposited by a previous pass and reducing the problem of ink spreading.
Claims41
A method, for use with an inkjet device, of printing an area of a substrate in a plurality of passes using curable ink, the method comprising depositing a first pass of ink on the area;
- partially curing ink deposited in the first pass such that an exposed surface of the partially cured ink is in non-solidified form;
- depositing a second pass of ink on the area;
- and
- fully curing the ink on the area.

An inkjet device, for printing on an area of a substrate using ink, comprising
- a printer carriage having one or more printheads and a radiation source for at least partially curing ink emitted by one or more printheads;
- and
- a radiation source for substantially fully curing the ink,
- wherein the radiation source for partially curing the ink is arranged to move with the one or more printheads, and the radiation source for substantially fully curing the ink is arranged such that the one or more printheads can move relative to such radiation source.
