3. Setup
The Uni-ball Signo Broad Point Gel Pen requires minimal setup. It is ready for use directly out of the packaging.
- Uncap the Pen: Gently pull the cap off the pen to expose the broad point nib.
- Initial Strokes: If the ink does not flow immediately, make a few small scribbles on a scrap piece of paper to prime the ink flow. This is rarely necessary due to the pen's smooth ink delivery system.
4. Operating Instructions
Using your Uni-ball Signo Broad Point Gel Pen is straightforward:
- Writing Angle: Hold the pen at a comfortable angle, typically between 45 and 90 degrees to the writing surface. The broad point allows for flexibility in writing style.
- Pressure: Apply light to moderate pressure. The smooth gel ink requires minimal force for consistent lines.
- Drying Time: Allow a few seconds for the ink to dry, especially on non-absorbent or glossy surfaces, to prevent smudging. This is particularly important for left-handed users.
- Surface Compatibility: This pen performs exceptionally well on various surfaces, including dark paper, cardstock, and even some metallic or plastic surfaces.
5. Maintenance
Proper maintenance will extend the life and performance of your Uni-ball Signo Broad Point Gel Pen:
- Always Cap After Use: To prevent the ink from drying out and the nib from clogging, always replace the cap firmly after each use.
- Storage: Store pens horizontally or nib-down to ensure consistent ink flow. Avoid storing in direct sunlight or extreme temperatures. For long-term storage, an airtight container can help preserve ink life.
- Cleaning the Nib: If the nib accumulates dust or dried ink, gently wipe it with a soft, damp, lint-free cloth. Do not use harsh chemicals or abrasive materials.
