Claim Text:
1. An apparatus for distributing a hydrophobic material in a substrate comprising: a first roller; a second roller configured to engage the first roller to form a nip; a first heater operatively connected to the first roller and configured to heat the first roller to a first temperature that is greater than a second temperature of the second roller; a printhead having a plurality of inkjets configured to eject drops of hydrophobic material in a predetermined pattern on the second roller; and a substrate transport configured to move a substrate through the nip at least twice at a predetermined linear velocity of approximately 5 inches per second to enable the first roller to engage a first side of the substrate and the second roller to engage a second side of the substrate to melt the two predetermined patterns of hydrophobic material to and enable the two predetermined patterns of hydrophobic material to penetrate into the second side of the substrate in response to a temperature gradient in the nip between the first roller and the second roller.
