Roller Coverings - OFFSET

Sheet-fed offset: inking rollers

In the modern offset and web-offset systems the rollers’ covering plays an important role in the qualitative output and makes the system more economical to run. TecnoRulli® has prepared and tested ideal coverings for the most demanding printers according to the most severe conditions. The formulation of the compounds has allowed us to obtain a product which has a high resistance to heat, to solvents and to abrasion. The product has a dimensional stability, a superficial elasticity and softness together with a guarantee of optimal qualitative and long lasting performance.

SAK S

The new compounds of the SAK S based on top quality acrylo-nitric polymers offer excellent features of chemical resistance and duration in the most demanding working conditions also with HYBRID INKS use. The latest original formulas, prepared by the technical staff in the chemical and physics laboratory, were created by using an advanced study technology allowing excellent characteristics to be obtained: excellent resistance to abrasion; low heat development; excellent surface softness; ease of cleaning; excellent elasticity; good resistance to cracks and age. The new SAK S has been tested over a long period with the products of the new ecological series: inks, additives and solventless cleaning products (V.C.A.), guaranteeing the Customer the purchase of a state-of-the-art covering which is ready for the future.

Main compounds available:
SAK S30 for inking and dampening machines with sleeve, grey
SAK S40 for distributor roller, grey

The SAK S series has been designed to obtain:
- Excellent resistance to abrasion
- Low heat build up
- Hardness stability
- Good resistance to cracks and aging
- Easy cleaning<
- Excellent elasticity

Main compounds are:
S 30 for inking rollers and dampening with sleeve
S 40 for distributor and ink vibrator rollers


SAK M

SAK M compounds have been formulated for alternative use of both conventional oil inksand UV drying inks. High level of print performance, along with excellent chemical resistance to the aggressive effects of UV products.
The duration and the printing quality of the SAK M rollers is the same as that obtained with the specific compounds for conventional or U.V. inks.
The new SAK M series does not limit the use of U.V. inks.
Main compounds are:
M 31 for inking and dampening rollers
M 41 for Inking and Distributor rollers


Offset with both conventional and U.V.-cured inks: SAK M also for HYBRID INKS

SAK M compounds satisfy the demands of printers also using U.V. inks in plants normally used for offset printing with conventional inks. The duration and the quality yield of rollers covered in SAK M is comparable with that obtained with specific compounds for conventional inks alone or U.V. inks alone. The new SAK M series does not limit the use of U.V. inks.
Main compounds available:
SAK M31 inkers, black
SAK M41 distributors, black


U.V. Offset Tecnolast V

For printing with U.V. drying inks, Tecnorulli has reworked the TECNOLAST V compounds, increasing their resistance to all aggressive products used in the lines that include U.V. drying plants and improving dynamic yield, distribution capacity, inking properties and dimensional stability. All the coverings of the series are highly sensitive to conventional inks and their solvents to such an extent that they may not be used even for a short period.
The mainly key points of those compounds are:

  • Improved chemical resistance
  • Increased service time
  • Better Distribution and Inking features
  • Excellent dimensional stability

Rollers covered with new Tecnolast V series, are more resistant to all kinds of UV inks and UV cleaners.
Main compounds are:
V 11: for inking rollers (new! Special soft compound)
V 13: for inking and dampening rollers
V 14: for inking and distributor rollers
