Abstract
Disclosed herein is a printing system is described having a first printer including a fuser employing fuser oil, and a coater disposed upstream or downstream from the first printer and being configured to deposit a wax coating on a portion of the substrate. A corresponding method and a substrate also are described. The system, method and substrate are useful for preparing MICR encoded documents such as checks.
Claims22
A printing system comprising:
- a first printer configured to print a first set of data on a substrate, the first printer including a fuser employing fuser oil, and
- a coater disposed upstream or downstream from the first printer, the coater being configured to deposit a fuser oil-mitigating wax coating on a portion of the substrate.
A method comprising:
- coating a portion of a document surface with a fuser oil-mitigating wax to form a coated portion,
- performing a printing process on the document to produce a pre-printed document, the printing process resulting in the presence of fuser oil on the surface of the document, and
- applying a magnetic image to the coated portion using a magnetic ink character recognition encoding process.
A substrate comprising a first surface having fuser oil thereon, a portion of the first surface including a wax coating having a plurality of cracks therein through which a portion of the fuser oil is absorbed, and a magnetic ink image having a magnetic signal strength of at least 80% formed over the wax coating.
