Claims15
A roller arrangement for printing apparatus, the roller arrangement comprising:
- a first roller, the first roller comprising a plurality of cells, each of the plurality of cells receiving an amount of a coating material;
- and
- an extractor to remove at least a portion of the coating material from a selected set of the plurality of cells.
A method for forming a pattern of a coating material on a first roller for transfer to a second roller, the first roller comprising a plurality of cells, the method comprising
- depositing an amount of a coating material in each of the plurality of the cells of the first roller;
- removing at least a portion of deposited coating material from a selected set of plurality of cells of the first roller to form a pattern of the coating material on the surface of the first roller.
A method for printing a pattern onto medium, the method comprising
- depositing a coating material over the surface of a first roller, the first roller comprising a plurality of cells and an amount of the coating material is deposited into each of the plurality of cells;
- removing at least a portion of deposited coating material from a selected set of the plurality of cells of the first roller to form a pattern of the coating material on a surface of the first roller;
- transferring the formed pattern from the surface of the first roller onto a surface of a second roller, the second roller being in contact with at least a portion of the medium to print the pattern transferred onto the surface of the second roller onto at least a portion of the medium.
Apparatus for printing a pattern onto medium, the apparatus comprising
- a first roller comprising a plurality of cells;
- a second roller in contact with the first roller and medium;
- a coating material deposition arrangement to deposit an amount of coating material in each of the plurality of cells;
- an extractor to remove at least a portion of deposited coating material from a selected set of the plurality of cells to form a pattern on the surface of the first roller for transfer to the surface of the second roller and to transfer from the surface of the second roller to at least a portion of the medium.
