  • Method of printing
    Patent number: 8960889
    Abstract: The application describes a method and apparatus for controlling surface finish in the printing of a substrate in a plurality of passes using a curable print material and an ink jet printer having a radiation source. A first set of passes is carried out, including depositing ink on the substrate and emitting radiation from a radiation source toward the deposited ink. The emitted radiation applies a dose of radiation in a first range. A second set of passes is then carried out to deposit ink on the substrate. Further radiation is emitted from a radiation source toward the deposited ink, the emitted radiation applying a dose of radiation in a second range different from the first range.
