Curl prevention using a transverse slit on tray-loaded film for printers

A sheet of media suitable both for manual feeding as well as automatic tray-loaded feeding into inkjet printers comprising:

• an elongated film sheet having a finished film portion having a length and a leader portion, said leader portion being separatable from said finished film portion after a printing operation is completed;
• a backing sheet having a thickness and width underlying said elongated film sheet for providing the sole connection for holding together said finished film portion and said leader portion during the feeding of said film sheet as well as during the printing operation, said backing sheet underlying the entire leader portion and joined together therewith along a first junction by an adhesive layer completely covering said junction, said backing sheet also underlying a forwardmost lateral strip of said finished film portion and jointed together therewith along a second junction by an adhesive layer completely covering said junction, said backing sheet being separatable from said finished film portion after a printing operation is completed;
• a lateral slit in said backing sheet in an intermediate location in said first junction, said lateral slit extending completely through said thickness of said backing of said lacking sheet and continuously across the entire width of said backing sheet to provide an expansion and contraction joint during any time period when multiple sheets of media are stacked in a tray-loaded printer, and
• wherein a composite laminant is formed by said backing sheet, said adhesive layer along said first and second junctions, said film leader, and said forwardmost lateral strip of said finished film portion in order to facilitate the manual feeding and the tray-loaded feeding media into the printer.
