Embodiment Construction

[0017] For a general understanding of the context of, and details of, the systems and methods disclosed herein, reference is made to the accompanying drawings. In the drawings, like reference numerals are used to refer to like elements throughout. As used herein, the term "printer" includes any device that produces an image on a medium with resin or colorant, such as a digital copier, book-finishing machine, facsimile machine, multifunction machine, and the like. In the description below, the printer is also configured to deposit molten wax, phase change ink, or other hydrophobic material onto a porous substrate such as paper. Although the printers described below are inkjet printers and in some embodiments the hydrophobic phase change material may be phase change ink, in some configurations the hydrophobic material is an optically clear wax or other material that does not have a particular color. The visual representation of the hydrophobic material provided below is for exe...

Abstract

The invention provides a method of forming hydrophobic structures in a hydrophilic print medium, the method including operating a plurality of inkjets to form an arrangement of hydrophobic material on first side of a print medium that moves in a process direction at a predetermined velocity. The method further includes moving the print medium through a convection heater at the predetermined velocity to enable the hydrophobic material to penetrate the print medium to form hydrophobic structures within the print medium.

Description

technical field [0001] The present disclosure relates generally to systems and methods for controlling the deposition of hydrophobic materials in porous substrates, and more particularly, to systems and methods for forming hydrophobic structures in hydrophilic print media in inkjet printing systems . Background technique [0002] A paper-based chemical assay device includes a paper substrate, waxes that form fluidic channels and other fluidic structures in the paper, and one or more reagents. Common examples of paper-based chemical assay devices include biomedical test devices that are fabricated from paper and perform biochemical assays and diagnostics in test fluids such as blood, urine, and saliva. The device is small, lightweight and low cost, and has potential applications in healthcare, military and homeland security, for example as a diagnostic device. Prior art paper-based diagnostic devices are limited in fluid feature resolution and manufacturing compatibility du...
