- the strength of the surface modification of printed sheets by the plasma on the respective substrate is adjustable. This results in differences between different substrates, as they react differently with the free radicals from the plasma. This reaction may also be variable for inherently similar materials due to variable manufacturing processes, transportation and storage conditions. Therefore, the strength of the surface modification is specifically influenced, with the main influence variable being the strength of the Plasma is. However, the duration of the plasma action, the type of gas used and the pressure of the blast air flow at the nozzles also have an effect.
