Abstract
Embodiments of the invention are directed to a multi-component nib structure and marking device for selectively generating primary marks and a secondary marks for lettering and shading. The marking device includes a multi-component nib structure, an ink source. The multi-component nib structure generally includes a first nib component, a second nib component, and optionally, a transfer component between the first nib component and the second nib component. In other aspects, the multi-component nib structure may allow lettering with different tones creating, for example, an ombre effect.
Claims21
A multi-component nib structure for a marking device for selectively generating marks on a receiving surface, wherein the marking device comprises:
- an ink reservoir;
- and
- a multi-component nib structure having a tip portion, a shank portion, a first component, and a second component,
- wherein the first component is enveloped by the second component,
- wherein the first component has a first porosity and wherein the second component has a second porosity.
(canceled)
A marking device for creating multi-tonal lettering marks on a surface, the marking device comprising:
- an ink reservoir;
- a multi-component nib structure having a tip portion, a shank portion, a first component, and a second component, wherein the first component comprises a first ink transfer property and wherein the second component comprises a second ink transfer property;
- and
- a nib boundary between the first component and the second component, wherein the nib boundary is configured to control a flow of ink between the first component and the second component.
A marking device for creating shadowed lettering, the marking device comprising:
- an ink reservoir;
- a multi-component nib structure coupled to the ink reservoir having a first component directly adjacent to a second component with a boundary component located between the first component and the second component;
- and
- a housing for enclosing at least a portion of the multi-component nib structure and the ink reservoir.
