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.

A method of 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 to produce a printed image having a first surface finish in a first region and a second surface finish in a second region wherein one of the surface finishes is more glossy than the other, the method comprising:
- carrying out a first set of passes, a pass of the first set of passes including depositing ink on the substrate and emitting radiation from a radiation source toward the deposited ink, the emitted radiation applying a dose of radiation in a first range,
- subsequently carrying out a second set of passes, a pass of the second set including depositing ink on the substrate and emitting radiation 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, wherein the first set of passes effects printing of ink onto the first region of the substrate and the second set of passes effecting printing of ink onto the second region of the substrate different from the first region, wherein the first dose range and the second dose range are such that the curing effected of the printed ink in the first set of passes is different from the curing effected of the printed ink of the second set of passes, wherein the first dose and the second dose are such that the surface finish of the printed ink of the first set of passes is different from the printed ink of the second set of passes.
A method of 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, the method comprising:
- carrying out a first set of passes, a pass of the first set of passes including depositing ink on the substrate and emitting radiation from a radiation source toward the deposited ink to produce a printed surface having a first surface finish,
- subsequently carrying out a second set of passes, a pass of the second set including depositing ink on the substrate and emitting radiation from a radiation source toward the deposited ink, to produce a printed surface having a second surface finish different from the first.
A method of printing an image on a substrate in a plurality of passes, using curable print material and an ink jet printer having a radiation source, wherein the image to be printed includes heavy print areas for which a relatively high dose of ink is to be deposited and further includes light print areas for which a relatively low dose of ink is to be deposited, the method comprising:
- depositing the ink on the substrate to form the image, the ink deposited including the dose of ink required to print the image, and further including an additional dose of ink, the additional dose of ink being deposited in a light area of the printed image.
