Abstract
A printing system includes a fixer printhead, an overcoat printhead and at least one ink printhead. The at least one ink printhead depositing drops of a colored ink on a medium. The fixer printhead deposits drops of a fixer onto the deposited drops of the colored ink. The overcoat printhead deposits drops of an overcoat onto the deposited drops of the colored ink.
Claims42
An inkjet printing system, comprising:
- at least one ink printhead for depositing drops of a colored ink on a medium;
- a fixer printhead for depositing drops of a fixer onto the deposited drops of the colored ink;
- and
- an overcoat printhead for depositing drops of an overcoat onto the deposited drops of the colored ink.
An inkjet printing apparatus, comprising:
- a carriage assembly movable in a scanning direction and adapted for receiving
- at least one ink printhead for controllably depositing a colored ink on a medium,
- the carriage further adapted for receiving a fixer printhead for controllably depositing a fixer onto the deposited drops of the colored ink,
- the carriage further adapted for receiving an overcoat printhead for controllably depositing an overcoat onto the deposited drops of the colored ink;
- and
- a processor programmed to send swath data to the at least one ink printhead and the fixer and overcoat printheads during printing.
Apparatus comprising a processor programmed to send swath data to an ink printhead, a fixer printhead, and an overcoat printhead during printing, wherein the ink printhead deposits drops of a colored ink onto a medium, wherein the fixer printhead deposits drops of a fixer onto the colored ink, and wherein the overcoat printhead deposits drops of an overcoat onto the colored ink.
A program for causing a processor to generate swath data for a printer including ink, and first and second protective coating printheads, the first and second protective coating printheads containing fluids that, when in contact, form a protective coating, each printhead having a plurality of separate ink ejection elements, the program instructing the processor to generate swath data only for a subset number of ink ejection elements in each printhead so that ink is deposited and the fixer and overcoat are deposited on the ink.
An article for a processor, the article comprising:
- computer memory;
- and
- instructions encoded in the memory to cause the processor to send swath data to ink, fixer and overcoat printheads.
A method of using ink, fixer and overcoat printheads to print on a print medium, the method comprising:
- sending swath data to the ink printheads during a first pass, the swath data causing the ink printheads to deposit ink on the medium during the first pass;
- and
- sending swath data to the fixer and overcoat printheads during a second pass, the swath data causing the ink printheads to deposit ink on the fixer and the overcoat during the second pass.
A method of printing an image with an inkjet printer, comprising:
- depositing drops of a colored ink on a medium;
- depositing drops of a fixer onto the deposited drops of the colored ink;
- and
- depositing drops of an overcoat onto the deposited drops of the colored ink;
- the overcoat and fixer reacting to form a protective coating for the ink.
A program storage element for a processor, comprising:
- computer memory;
- and
- instructions encoded in the memory to cause the processor to control ink ejection elements to deposit drops of a colored ink on a medium, and deposit drops of a fixer and an overcoat onto the deposited drops of the colored ink.
