Abstract
Inkjet printing apparatus includes a print head for directing radiation curable ink toward a substrate and a curing device for directing radiation toward ink received on the substrate. The apparatus includes a computer for determining desired dwell times for the ink based on characteristics of the substrate and the ink. A control device connected to the computer varies the dwell time in accordance with the desired dwell time as determined by the computer.
Claims25
Inkjet printing apparatus for radiation curable ink comprising:
- a support for receiving a substrate;
- a print head for directing radiation curable ink toward a substrate received on the support;
- a curing device for directing radiation toward ink received on the substrate;
- a controller having an input for receiving one or more characteristics of the substrate and one or more characteristics of the ink, the controller including a computer for determining a desired dwell time for the ink based on the characteristics of the substrate and the ink;
- and
- a control device connected to the controller for varying the dwell time in accordance with the desired dwell time determined by the computer.
3 more elements
A method of inkjet printing comprising:
- selecting a radiation curable ink;
- selecting a substrate;
- entering at least one characteristic of the ink and at least one characteristic of the substrate into a computer;
- determining a preferred ink dot gain when the selected ink is printed onto the selected substrate;
