Cost effective processing of plastic plates and film sheets is very important in manufacturing print products. Quality requirements for high gloss products are very demanding. Even the smallest scratch on the surface or manufacturing steps that are not completely clean can result in waste.
Plastic plates and film sheets are separated from a stack into individual units for further processing. Before the individual plastic plates or film sheets are cut to size, a check must determine that only one plate or sheet has been supplied. If not, the equipment can be damaged and the material will be unusable.
Double sheet detection increases equipment life and minimizes material waste.
