 Poliro "roll-up" rollers, lithography, nitrile rubber / cotton flock
| Some caracteristics of nitrile rubber with "cotton-flock"
- As is visible on the image, the surface is rough because of the cotton fibres
- The roll has similar caracteristics as a leather roll, it is also capable of absorbing moisture. This reduces the possibility of emulgation (mixing of ink and water)
- Can transfer more ink than the nylon flock roll
- Suitable for proof prints and printing earth tones
- In the offset-industry these rolls are used to keep the offset rollers damp
- These rollers can also be used to absorb the excess moisture from etching paper
- Similar as the structured rollers from Graphic Chemical and Takash (rough surface and moisture absorbing)
