3. Technical advice
- In the process of using the roller for a while, the surface is hardened, so the roller should be re-ground so that the surface is evenly rounded, elastic, will reduce the pressure on the roller, thereby increasing the used time.
- When not using the roller, ink and oil must be cleaned from the surface and must be placed on the rack.
- Should be kept in a cool and dry place, away from sunlight and moisture. Appropriate temperature below 30 degrees Celsius.
- When transporting the roller, it must be carefully placed to avoid the rubber surface in contact with hard objects, easy to concave, scratch the surface.
