Posca marker setup instructions:
- Shake the pen vigorously (do not remove the cap yet).
- The internal ball mixes the color when shaken.
- Pump the tip of the pen onto scrap paper until the tip is completely filled with color. Always test the flow on scrap paper first. You can also wipe the tip with a cloth during use. If the color flow is sluggish, put the cap back on to avoid splashes, shake the pen again, and pump the tip once more. Pump again, and you can continue.
Permanence of colors on different surfaces:
- Paper, cardboard, and primed canvas, and other porous surfaces absorb the color so that it remains permanent.
- To achieve permanent color on stone, plastic, metal, and wood, apply varnish on top.
- Color on fabric is more permanent when ironed from the reverse side. After more than 20 washes, the color may start to fade, allowing you to redraw designs with Posca markers.
- For ceramics, you can achieve permanent color by baking at 220 degrees Celsius for 45 minutes, then applying varnish.
- For porcelain, you can achieve permanent color by baking at 160 degrees Celsius for 45 minutes, then applying varnish.
- For glass, you can achieve hand-washable color by baking at 160 degrees Celsius for 45 minutes, then applying varnish.
