The method further includes determining a secondary treatment area through a secondary template including secondary apertures, marking the secondary treatment area along borders of the secondary apertures to outline a grid of secondary tegulae, and delivering a tattoo removal fluid to the secondary tegulae in a second treatment session. ## Claims ### Claim 1 A method for removing a tattoo through patterned trans-epidermal pigment release, the method comprising: determining a first treatment area of skin of a patient through a primary template, the primary template comprising primary apertures, wherein the primary apertures are circular apertures; marking the first treatment area of skin of the patient along borders of the primary apertures to outline a grid of primary tegulae; delivering a tattoo removal fluid to primary tegulae in a first treatment session; determining a secondary treatment area of skin of the patient through a secondary template, the secondary template comprising secondary apertures, wherein the secondary apertures are non-circular and non-polygonal apertures; marking the secondary treatment area along borders of the secondary apertures to outline a grid of secondary tegulae, wherein the secondary tegulae border the primary tegulae; and delivering, in a second treatment session, tattoo removal fluid to the secondary tegulae. ### Claim 2 (depends on 1) The method of claim 1, wherein delivering the tattoo removal fluid to the secondary tegulae isolates a plurality of remaining tattooed areas in a grid of tertiary tegulae, and wherein the method further comprises delivering tattoo removal fluid to the tertiary tegulae in a third treatment session. ### Claim 3 (depends on 1) The method of claim 1, wherein the non-circular and non-polygonal apertures of the secondary template border three primary tegulae. ### Claim 4 (depends on 1) The method of claim 1, wherein the tertiary tegulae are a same shape as the non-circular and non-polygonal apertures of the secondary template. ### Claim 5 (depends on 1) The method of claim 1, wherein the primary template is flexible to conform to a non-flat surface of skin of the patient, and wherein the secondary template is flexible to conform to the non-flat surface of skin of the patient. ### Claim 6 (depends on 5) The method of claim 5, further comprising securing in place the primary template on the non-flat surface of skin of the patient while marking the first treatment area. ### Claim 7 (depends on 1) The method of claim 1, wherein the secondary tegulae and the tertiary tegulae are the same shape, and wherein the primary tegulae are bordered only by the secondary tegulae and the tertiary tegulae. ### Claim 8 (depends on 1) The method of claim 1, wherein to remove the entire tattoo, the tattoo removal fluid is delivered only in a total of three treatment sessions. ### Claim 9 (depends on 1) The method of claim 1, further comprising: placing a photogrid over a tattoo of the patient; photographing the photogrid and tattoo at a plurality of angles to form a plurality of photographs; importing the photographs into a computer and processing the photographs to form a morphed image comprising a flattened tattoo image; outlining tattoo elements in the morphed image for removal; and cutting a custom template based on the outlining of the morphed image, wherein the primary template is the custom template. ### Claim 10 (depends on 1) The method of claim 1, wherein the primary template comprises a linear pattern of elongated apertures. ### Claim 11 (depends on 10) The method of claim 10, wherein the primary template and the secondary template are the same, and wherein the secondary apertures are the elongated apertures. ### Claim 12 A method for removing a tattoo through patterned trans-epidermal pigment release, the method comprising: determining a secondary treatment area of skin of a patient through a primary template, the primary template comprising primary apertures; marking the secondary treatment area of skin of a patient along borders of the primary apertures to outline a grid of secondary tegulae with a primary lattice tegulae between the secondary tegulae; delivering, in a first treatment session, a tattoo removal fluid to the primary lattice tegulae between the secondary tegulae to isolate secondary tegulae; and delivering, in a second treatment session, tattoo removal fluid to the secondary tegulae. ### Claim 13 (depends on 12) The method of claim 12, wherein the primary apertures are octagonal polygons in a rhomboid pattern. ### Claim 14 (depends on 12) The method of claim 12, wherein to remove the entire tattoo, the tattoo removal fluid is delivered only in a total of two treatment sessions. ### Claim 15 (depends on 12) The method of claim 12, further comprising: placing a photogrid over a tattoo of the patient; photographing the photogrid and tattoo at a plurality of angles to form a plurality of photographs; importing the photographs into a computer and processing the photographs to form a morphed image comprising a flattened tattoo image; outlining tattoo elements in the morphed image for removal; and cutting a custom template based on the outlining of the morphed image, wherein the primary template is the custom template.
