Abstract
Systems and methods relating to improved printable magnetic sheet materials compatible with high-volume roll-to-roll printing processes using roll-fed presses. When implemented, the system permits existing roll-to-roll printer to generate sheet-magnet promotional materials that are adherable to various material substrates, such as, for example, mailers, phone books, etc.

- a low-tack adhesive layer applied to an upper side of the carrier layer;
- and
- a high-tack adhesive layer applied to a lower side of the carrier layer,
- wherein the printed magnet label is configured so that the printed magnet label can be adhered to a surface of an object and then the printed magnet can be releasably separated from the printed magnet label while the multi-layer adhesive backing multi-layer sheet remains attached to the surface of the object or item, and
- wherein the low-tack adhesive layer remains attached to a lower side of the protective layer after the printed magnet is releasably separated from the multi-layer adhesive backing portion assisting attachment of each printed magnet to the surface of the object or item.
A method of converting a continuous printable magnetizable multi-layer sheet into printed magnet labels, said printable magnetizable multi-layer sheet being compatible with a continuous roll-to-roll printing process, the method comprising the steps of:
- providing a roll of the continuous printable magnetizable multi-layer sheet having a first side and a second side, said first side having a printable surface configured to be receptive to applications of printed indicia and said second side having a protective coating, said continuous printable magnetizable multi-layer sheet comprising:
- a continuous printable magnetic portion, comprising:
- a magnet layer;
- a printed layer applied to an upper side of the magnet layer;
