The Mechanics of a
Successful Flexographic Print Run.
In the Long Run,
the Difference is the Cushion.
Speed, quality and price – you know that’s what your customers look for from a flexographic print run. And one of the most important factors in delivering all three is often overlooked: the cushion mounting tape.
A Unique Open-Cell Urethane Cushion
The key is our unique open-cell urethane technology.
Our urethane cells “bounce back” to their original state instead of breaking down under the constant pounding of your presses. So the tape you remove in demount has the same qualities as the tape you mounted in set up. The result is millions of high- quality impressions.
The Value of Consistency – Over Millions of Impressions
The consistent performance of R/bak SA 2000 means you can make millions of impressions at faster speeds without making adjustments.
You save time, money and aggravation.

The Right Cushion for Each Job – from Solids to Screens
R/bak SA 2000 tapes deliver award-winning quality for all your flexographic print jobs.
With three levels of compressibility, R/bak SA 2000 offers the right cushion for precise results across the board, from line to process.
Better Print Quality from Start to Finish
With R/bak SA 2000 cushion mounting tapes you can run even the largest jobs, knowing the results will be there. Because only the compress- ibility of R/bak open-cell urethane holds up to the rigors of flexographic printing.
Stop wasting time and money making on-press adjustments to achieve the results your customers demand. Instead, make a single business adjustment: change your tape to R/bak SA 2000. And deliver quality time and time again.
As Run-time Increases, the Superior Quality of R/bak SA 2000 Remains Consistent.

The Mechanics of a
Successful Flexographic Print Run.
Nel lungo periodo,
la differenza è il Cushion.
Velocità, qualità e prezzo sono le richieste che provengono dai clienti della stampa flexo. Ma uno dei fattori spesso trascurato è l'ammortizzante.
Un esclusivo Cushion in uretano a cellule aperte Le nostre cellule in uretano sono “bounce back”, si mantengono cioè nel suo stato originale nonostaste i numerosi passaggi e pressioni in fase di stampa, garantendo qualità e lunga durata.
Il valore della consistenza – Oltre a milioni di soggetti stampati Le prestazioni costanti di R/bak SA2000 consentono di ottenere milioni di soggetti stampati alle velocità più elevate senza
modificare le proprie dimensioni e consistenza, che si traduce in risparmio di tempo e di denaro.
Qualità di stampa dopo 1 ora e 45 minuti con medium PE tape, senza regolazioni aggiuntive.

Il Cushion giusto per ogni lavoro – dal fondo pieno al retino
L'ammortizzante R/bak SA 2000 offre una qualità riconosciuta per tutti i lavori di stampa flexo. Sviluppato con tre livelli di compressione, R/bak SA 2000 è il giusto Cushion per risultati di qualità
Smetti di sprecare denaro e tempo per eseguire regolazioni di compensazione sul processo di stampa. Per ottenere ciò che chiede il cliente è sufficiente una sola operazione: cambia il tuo ammortizzante con R/bak SA 2000.
In questo modo fornirai sempre qualità.
Con l'aumento del tempo, la qualità superiore di R/bak SA 2000 rimane costante

The Science Behind the Art of Better Flexographic Results.
The big quality difference between R/bak SA 2000 and other tapes can best be seen by taking a microscopic look inside the foam.
Open-cell urethane bounces back over and over again so that the tape provides the same level of cushioning no matter how many times it is compressed. Closed-cell polyethylene breaks down in use, not bouncing back and resulting in loss of ink density.
