The minimum and maximum thickness that can be processed refer to materials having standard characteristics. That can be found on the market. However, it is very important to underline that every material listed above can be processed in tension range mentioned in Section-1.9 & 1.10.
It has to accept reels already finished by other. For this reasons, machine’s each function-speed, tension, pneumatic pressure, aligner, mechanical sensibility- is finely adjustable in the available range.
As a consequence the operator’s experience and ability that will be needed to choose, among the different possible combinations (as explained above), the adjustment of parameters, which will achieve the optimum Printing results & speed.
