Kits and methods of treating a substrate prior to formation of an image thereon

摘要

Methods and kits for treating a fibrous substrate prior to forming an image thereon are provided. The method can include positioning a treatment sheet adjacent to the fibrous substrate, transferring a salt (e.g., calcium chloride, magnesium chloride, or a mixture thereof) from the treatment sheet to the fibrous substrate using a wetting solution (e.g., an aqueous solution, such as water) to carry the salt from the treatment sheet into the fibrous substrate, and drying the fibrous substrate such that the salt remains in the substrate. For example, the transfer of the salt from the treatment sheet into the fibrous substrate can be accomplished via pressing the backside of the treatment sheet such that the wetting solution flows from the treatment sheet into the fibrous substrate while carrying the salt.

1. A method of treating a fibrous substrate prior to forming an image thereon, the method comprising:
positioning a treatment sheet adjacent to the fibrous substrate, wherein the treatment sheet comprises a base sheet saturated with a salt, the salt comprising calcium chloride, magnesium chloride, or a mixture thereof, wherein the treatment sheet is free from any liquid when positioned adjacent to the fibrous substrate; thereafter, adding a wetting solution to a backside of the treatment sheet, wherein adding the wetting solution to a backside of the treatment sheet comprises: spraying the backside of the treatment sheet with the wetting solution; or positioning a wet sheet adjacent to the backside of the treatment sheet, wherein the wet sheet is saturated with the wetting solution, and pressing the wet sheet to pass the wetting solution from the wet sheet through the transfer sheet and into the fibrous substrate; transferring the salt from the treatment sheet to the fibrous substrate using the wetting solution to carry the salt from the treatment sheet into the fibrous substrate; and drying the fibrous substrate such that the salt remains in the substrate.
