processing steps may include printing imaging folding sealing separating cutting perforating scoring adhering and the like typically a product such as with the present invention is provided in an intermediate condition so that a customer can add or manipulate the intermediate to create the final or desired end product such as a sealed self mailer or a sealed communication piece for business or personal use 0039 fig1 illustrates the windowed mailer intermediate of the present invention the mailer intermediate includes a substrate depicted by reference to numeral 10 the substrate 10 may be of any suitable material that is capable of receiving imaging and or printed indicia such as bond stock paper 20 or 24 pound stock plastic films such as polyethylene based materials tag or card stock generally composed of cellulosic material and the like the substrate 10 as depicted in fig1 may be divided into a plurality of panels through the use of lines of weakness such as score lines or perforations by dividing the substrate 10 into one or more panels the substrate 10 may be folded upon itself to create an assembly that can be used for mailing or delivery once folded if a single fold line is provided for example medially of the cut sheet the sheet would be folded onto itself to create a u201c v u201d fold mailer if two fold or score lines are provided the mailer could be folded into a u201c c u201d or u201c z u201d folded mailer the score lines dividing the panels need not be equal in dimension in order that u201c eccentric.
