Introduction
The uni Posca PC-1M Acrylic Paint Markers are versatile, water-based paint pens designed for a wide range of creative projects. Featuring an extra-fine 0.7mm bullet tip, these markers are suitable for detailed work, outlining, coloring, and adding precise markings on over 50 different surfaces. The non-toxic, water-based pigment formula is alcohol-free, waterproof, and lightfast, ensuring vibrant and lasting results.
Setup
- Shake Well: Before each use, ensure the cap is securely on and shake the marker vigorously. This mixes the paint pigment for consistent color flow.
- Prime the Tip: Press the tip down several times on a scrap piece of paper until the paint begins to flow. This saturates the tip with ink.
- Reversible Tip: The PC-1M markers feature a reversible tip. If the tip becomes worn or dry, you can pull it out and flip it to use the other side.

Operating
Posca PC-1M markers are designed for precision and versatility. Their extra-fine tip allows for detailed work, while the opaque, water-based paint provides excellent coverage.
- Surface Compatibility: These markers work on a wide variety of surfaces including wood, metal, paper, rocks, plastic, canvas, ceramic, glass, and fabric.
- Application: The 0.7mm bullet tip is ideal for drawing fine lines, outlining, and filling in small areas. You can achieve graphic calligraphy effects or color wide areas with precision.
- Layering and Blending: Posca paint is layerable. For best results when layering colors, allow each layer to dry completely before applying the next to prevent blending. The water-based ink can also be diluted with water for blending effects before it dries.
- Drying Time: The paint dries quickly. On porous surfaces, it becomes permanent. On most smooth, non-porous materials, it can be erased.

Maintenance
- Cap Securely: Always replace the cap tightly after use to prevent the tip from drying out and to preserve the ink.
- Clean Tips: If the tip becomes clogged or dirty, it can be removed and rinsed with water. Ensure it is completely dry before reinserting.
- Storage: Store markers horizontally to ensure even ink distribution to the tip.
Troubleshooting
- No Ink Flow: If the marker is new or has not been used for a while, shake it well and re-prime the tip by pressing it down on scrap paper until the paint flows.
- Uneven Color: Ensure the marker is thoroughly shaken before use to mix the pigment evenly.
- Worn Tip: The PC-1M tip is reversible. If one side is worn, remove and flip the tip to use the fresh side.
