| Rollers |
| Metered Ink Film |
| In offset printing, the ink rollers have to apply a thin film of ink in a certain dosage to the printing plate. Therefore, particularly high demands are applied to metering rollers. The Rilsan-Roller by Böttcher meets all these requirements. |
| |
| Excellent Ink Receptiveness |
| Due to their chemical composition, Rilsan-Rollers are characterised by a distinctly favourable behaviour towards ink. This characteristic warrants good ink recipient and ink delivery behaviour and thus a defined transport of ink to the printing plate. These characteristics remain unaltered of course, when UV-inks are used. |

| Precise, Sophisticated Manufacture |
For the purpose of achieving the best possible surface for Rilsan-Rollers, specialised, ultra-modern surface machining equipment is available. This is the only way to achieve particularly high standards with regard to surface roughness, concentricity and cylindricity.
Concentricity: 0.01 mm
Cylindricity: 0.01 mm |

| Profiles for Better Ink Transfer |
| The favourable characteristics of Rilsan-Rollers can be even increased by producing special profiles, such as diamond or line profiles, grooves. Additionally, Rilsan is also suitable for laser and mechanical engraving. It is also possible to manufacture screen rollers for flexographic printing. |
| |
| Long Service Life |
| Due to their high ageing stability and excellent resistance against abrasion, combined with very good adhesion to the metal core, Rilsan-Rollers have a very high service life. |
| |
| Chemical Resistance |
| Rilsan-Rollers excel with outstanding resistance against contact media. This offers considerable advantages as compared to copper rollers: no oxidation when coming into touch with contact media; no change in the roller surface qualities. |
