Abstract
An artificial fingerprinting solution that includes a heated blend of glyceryl trioleate and artificial sebum configured to approximate the fingerprint oil of a human. The artificial fingerprinting solution may also be included in a kit that also includes an artificial fingerprint stamp that has an artificial fingerprint transfer member that imitates a human fingerprint and is capable of receiving and holding at least a portion of the artificial fingerprint solution when the artificial fingerprinting transfer member contacts the artificial fingerprint solution.
Claims20
A process comprising the steps of:
- preparing an artificial fingerprint forming material by combining at least glyceryl trioleate and an artificial sebum and heating the artificial fingerprint forming material to form the artificial fingerprint forming material, wherein the artificial fingerprint forming material is configured to approximate the natural fingerprint oil of a human;
- contacting the artificial fingerprint forming material with an absorbent material to form an artificial fingerprint contacting surface on at least one surface of the absorbent material;
- pressing an artificial fingerprinting transfer member of a stamping device into contact with the artificial fingerprint contacting surface of the absorbent material;
- and
- applying the artificial fingerprint transfer member to a surface of an appliance by pressing the artificial fingerprint transfer member of the stamping device into contact with the surface of the appliance to transfer at least a portion of the artificial fingerprint forming material in an artificial fingerprinting pattern to the surface of the appliance.

A process comprising the steps of:
- preparing an artificial fingerprint forming material comprising glyceryl trioleate and an artificial sebum wherein the artificial sebum comprises glycerol monostearate by heating the artificial fingerprint forming solution to form the artificial fingerprint forming material, wherein the artificial fingerprint forming solution is configured to approximate the natural fingerprint oil of a human;
- contacting the artificial fingerprint forming solution with an absorbent material to form an artificial fingerprint contacting surface on at least one surface of the absorbent material;
- pressing the artificial fingerprinting transfer member of a stamping device into contact with the artificial fingerprint contacting surface of the absorbent material;
- and
- applying an artificial fingerprint transfer member to a surface of an appliance by pressing the artificial fingerprint transfer member of the stamping device into contact with the surface of the appliance to transfer at least a portion of the artificial fingerprint forming solution in an artificial fingerprinting pattern to the surface of the appliance.

A process comprising the steps of:
- preparing a liquid artificial fingerprint forming material comprising glyceryl trioleate and a solid artificial sebum by combining the glyceryl trioleate and the solid artificial sebum and heating the glyceryl trioleate and the solid artificial sebum to dissolve the solid artificial sebum and form the liquid artificial fingerprint forming material, wherein the liquid artificial fingerprint forming material is configured to approximate the natural fingerprint oil of a human;
- contacting the artificial fingerprint forming material with an absorbent material to form an artificial fingerprint contacting surface on at least one surface of the absorbent material;
- pressing an artificial fingerprinting transfer member of a stamping device into contact with the liquid artificial fingerprint contacting surface of the absorbent material;
- and
- applying the artificial fingerprint transfer member to a surface of an appliance by pressing the artificial fingerprint transfer member of the stamping device into contact with the surface of the appliance to transfer at least a portion of the artificial fingerprint forming material in an artificial fingerprinting pattern to the surface of the appliance.
