History of tattoo technology

In a March 1999 interview, Sāmoan master tattooist Su‘a Sulu‘ape Paulo II recalled making a set of tools and showing them to his father. One of the men his father was tattooing asked Paulo to work on his legs. His father had begun the back; Paulo worked on a leg and left the gap between them for his father to finish. Toolmaking, a family practice and the wearer's invitation came together in his account. Paulo's interview with Sean Mallon

Tattoo technologies change both the movements artists make and how work is shared. A comb, a motor, a stencil and a body scan each organize part of that work. Their histories overlap, joining changes in materials with changes in how artists learn, share designs and work with a wearer.

01What the oldest evidence can tell us

Tattooing has no known inventor or securely dated beginning. Skin usually disappears, taking its marks with it.

Ötzi, whose body survived in Alpine ice, lived in the late fourth millennium BCE. A 2016 review of radiocarbon evidence identified his tattoos as the oldest preserved examples then known, correcting a competing claim about a Chinchorro mummy from South America. Deter-Wolf and colleagues

In 2018, researchers reported tattoos on two naturally mummified people from Gebelein in Egypt, also from the late fourth millennium BCE. Infrared imaging made indistinct marks legible, including two horned animals on a man's upper arm. Friedman and colleagues

Surviving marks can also suggest which tools made them. A study published in 2022 compared eight versions of one design on tattooist Danny Riday's leg. Riday and tattooist Mokonuiarangi Smith applied them with different tools and techniques. Co-author Maya Sialuk Jacobsen guided the making of skin-stitching tools. The team documented the marks over six months to build a reference for comparison. Experimental study

In 2025, researchers applied that reference to near-infrared images of a woman's tattoos from the Iron Age Pazyryk culture in the Altai Mountains. Dense, even outlines lacked the small edge marks the authors expected from building broad lines with one point. They inferred a multiple-point tool for those outlines and a finer, likely single-point tool for narrow details. They attributed some irregular edges to changes during preservation. The authors knew of no corresponding multiple-point implement in the region's archaeological record. Caspari and colleagues

An implement presents the reverse problem: identifying what it was used for. A sharp point could have served many purposes. In a 2019 account of their research, Andrew Gillreath-Brown and Aaron Deter-Wolf described an implement from deposits around 2,000 years old at Utah's Turkey Pen site: cactus spines bound to a wooden handle with yucca strips. They made replicas and used them on pig skin. Microscopy showed rounded tips and pigment deposits comparable to those on the archaeological object. The researchers' account

02Hand tools have their own histories

Hand tattooing includes different ways of making and organizing marks. Directly pushing a point, striking a tool with a mallet and drawing a pigmented thread through skin involve different tools and learned movements. Specific traditions give those movements their purposes.

In Sāmoan tatau, a tufuga ta tatau works with an ‘au, a toothed comb attached to a handle, and a sausau, the striking rod. Te Papa's collection record describes combs of different widths for fine lines, dots and larger dark areas. The shape of the working edge helps determine the mark, much as the arrangement of needles matters in an electric machine. Te Papa's ‘au record

The tools also change. Te Papa's record describes how nylon fishing line can replace coconut-fibre bindings, while plastic or metal can replace the turtle-shell plate that holds the comb. Changes in tool materials. In a 2016 interview, curator Sean Mallon described leading tufuga constructing tools with metal needles. He connected material changes to international conventions, diaspora clients and requirements for equipment that could be sterilized. The family practice Paulo recalled belongs to this continuing history of making and adapting tools. Mallon on changing tatau

Japanese tebori offers another example. A 2012 studio visit with Horimyo documented an artist whose design, ink mixing and application with a bamboo hand tool formed one practice. In the accompanying interview, he recalled using an imported machine before becoming an apprentice to an artist who worked entirely by hand. Continuing tebori, he explained, was a way to pass the technique on. He considered machines better suited to some designs and valued handwork as a discipline. Studio visit; Horimyo's interview

In a 2016 profile, Iñupiaq artist Holly Mititquq Nordlum described her work with Greenlandic Inuit artist Maya Sialuk Jacobsen as a way to bring women together. Their work included skin stitching, which uses a needle and pigmented thread, and training other Inuit women in Anchorage. The profile described colonial pressures that had disrupted the practice. Nordlum's 2016 profile

A May 2017 profile of Iñupiaq artist Sarah Whalen-Lunn, who trained with them, described her decision to reserve skin stitching and traditional patterns for Alaska Native recipients. The training was part of her effort to reconnect with her heritage. Whalen-Lunn's account

03Electric pens and tattooing machines

In 1876, Thomas Edison patented an office copying system built around a powered needle that perforated paper. A person guided the pen to write or draw while the motor drove the needle. Ink could then pass through the perforations to print copies. Edison's patent

A company booklet from that year described the rest of the work: writing over blotting paper, clamping the perforated sheet into a press and rolling ink across it. Electricity powered one step in a sequence the operator carried out. Company booklet, 1876

Samuel F. O'Reilly's tattooing-machine patent was granted on December 8, 1891. Its drawings show a motor above a tubular handle driving needles through an ink reservoir. A guide on the movable reservoir regulated how far the points projected. The motor supplied repetition, while the artist guided the tool. Five needles appear in the example, but O'Reilly explicitly allowed other numbers. O'Reilly's patent

The work behind a machine is harder to recover than its patent date. On January 16, 1898, The Sun credited Clarence Smith of Newark with adapting an electric pen for tattooing. A week later it reported O'Reilly's competing claim. The second article described O'Reilly trying a dental plugger and an Edison pen before making his own model and having a skilled mechanic build the machine. The competing claims leave priority unresolved. January 16 report; January 23 account

A contemporary profile shows how selectively artists could use electricity. In 1897, Gambier Bolton described Sutherland Macdonald doing outlines electrically while retaining Japanese hand tools for shading and heavier work. Bolton's 1897 profile

04Coil, rotary and pen describe different things

Charles Wagner's 1904 patent compared its electrical operation to an ordinary vibrating bell. Wagner's patent

In the familiar coil arrangement, energized electromagnets pull a metal bar, the armature, toward them. That movement opens an electrical contact. The magnetic pull stops, a spring returns the bar, and the contact closes again. Repeated rapidly, the cycle moves the attached needle bar. Percy Waters's 1929 patent describes this interaction of magnets, spring and adjustable contact. A separate finger switch on the grip let the artist control when the circuit was energized. Coil mechanism

O'Reilly's 1891 drawing shows a connecting rod running from the motor to a lever inside the handle. The lever rocks on a fixed pivot, moving the needle rod at its other end. Early motor-driven design

A rotary machine uses a rotating motor and a linkage to produce the needle's back-and-forth movement. Cheyenne identifies its HAWK Pen as a rotary machine with a DC motor. HAWK Pen drive

Pen refers to a machine's shape and how it is held. In Macdonald's 1894 specification, an electromagnet and spring moved a needle spindle back and forth inside an instrument handled like a writing pen. Shape and drive are separate choices in a tool's design. Macdonald's specification

05Buying tools and seeking guidance

A surviving kit in The Henry Ford's collection, dated around 1910, brings several technologies together. Its photograph shows electric machines, a row of colored vials and a printed instruction booklet. Tattoo kit, circa 1910

Suppliers offered guidance as well as tools. A Smith & Howard price list, dated around 1910 by Historic New England, advertised electric outlining and shading machines, hand needles, colors, design books and matching stencils. An advertised amateur outfit included hand needles, designs, stencils and directions. The company promised shipping by registered mail. Original price list and exhibit

In a letter that Potter & Potter dates around 1910–11, Jack O'Neil asked a correspondent to teach Frank tattooing. The request puts personal guidance alongside the suppliers' printed instructions. Photographed correspondence

06Replaceable parts and portable power

In a patent granted in 1989, Richard A. Piperato described a holder that served as a grip and part of a sealed container for the needle bar. He proposed plastic for the main body and caps and intended both the holder and needle assembly for disposal after one use. Breakaway fastenings were intended to make prior opening apparent. The assembly was designed to fit an existing electric tattoo machine. Piperato's patent

In the HAWK Pen, a replaceable needle cartridge fits inside a separate grip attached to the drive unit. The cartridge holds the needles within its own housing, and the manufacturer specifies it for a single use. The artist's equipment choices include both the machine and a continuing supply of compatible modules. HAWK Pen manual; Cartridge diagram

Power choices also rearrange the workbench. Brooklyn's 1903 report describes a small battery among Riley's equipment. Waters's 1929 patent allowed power from either a dry-cell battery or a transformer connected to a house circuit. On compatible FK Irons machines, the detachable PowerBolt II battery travels with the handpiece and displays voltage or frequency. These arrangements shift weight, cables and adjustment around the work area. Riley's equipment; Waters's power options; Battery controls and compatibility

07Color has a material history

Te Papa's record of a Sāmoan ‘au describes candlenut soot as an earlier pigment and commercial inks as the more common choice. Pigment and tool record

Smith & Howard offered colors by the jar and black ink in sticks. A separate directions sheet assigned the mixing to its reader. Buying commercial materials could still leave preparation to the artist. Price list; Directions sheet

Identifying a pigment calls for another set of tools. In a 2017 study, Betsy Jean Yakes and colleagues used Raman spectroscopy to measure characteristic responses to laser light. Their reference pigments, mostly powders, included carbon blacks, titanium dioxide whites and copper-based blues and greens. They organized the measurements into searchable libraries for comparison with other samples. Closely related compounds could give similar results, especially at low concentrations. The authors stressed that unknown compositions need other methods to confirm an identification. Yakes and colleagues

08A design needs a route to the body

A design can reach the body through drawing or transfer. In a 1903 report on Tom Riley's practice, Pat Brooklyn described designs drawn directly on skin with a brush or transferred from a drawing on tissue paper. The transferred drawing left a guide on the skin for Riley to follow with his needles. Brooklyn's report

Tattooist and archivist C. W. Eldridge remembers cutting acetate stencils in the 1970s, work that left a callus on his left hand. He describes scratching the design into the plastic, then making pencil rubbings that could be mailed to other artists. A guide for the tattooist could also carry an image between shops. Eldridge on stencils

ReproFX describes dyes held in wax in its freehand transfer paper, which responds to tracing pressure. Its thermal paper is made for stencil printers. Transfer papers

In a 2017 Brother profile, artist Paul Talbot described printing computer designs as paper stencils for transfer to skin. He wanted a portable printer of his own at conventions, where he had queued for shared equipment. Talbot's account

Digital design also changes the conversation with a client. Darwin Enriquez describes combining body scans with Procreate's 3D painting to study placement and preview designs. He also uses the app for stencil preparation and explores lighting digitally to plan a piece's appearance. Enriquez interview

A preview still requires interpretation. Tattoo artist Brad Wooten describes composition for a body as different from composition for a flat picture: the body has volume and moves. His custom brushes combine repeating geometric motifs with effects he would otherwise build on separate layers. He turns part of his own design process into a reusable tool. Wooten interview

09Robots are one branch of the story

A maker post by Appropriate Audiences, published in 2014, describes fitting a tattoo machine to a desktop 3D printer. Makers' account. The team's 2016 account of its later industrial-arm experiment describes turning a body scan into an editable digital model and using visual programming to project the design onto its surface. Industrial-arm account. Autodesk's account from that year describes exporting the pattern as commands for the robot. The designers still chose the pattern and where it would sit on the body. Autodesk's contemporary account

Blackdot's October 2023 launch announcement presented an automated tattooing platform with designs from artists including Tyler Hobbs and Omer Tunca. The company said artists could offer one-off designs or limited editions and earn a royalty each time a design was used. Blackdot launch announcement. In an interview that month, Hobbs described drawing birds by hand, digitizing them and altering their curves and lines in code. He saw the project as a way for digital artists to participate in tattooing. Hobbs's interview

tatbot, the open-source tattoo robot, belongs in this field of experiments. A public livestream from 2025 records its creator tattooing his own leg with the robot. 2025 livestream. Its robotic arm positions and orients a tattoo pen to follow curved surfaces. Project demonstrations. Its tattoo artwork is generated entirely with AI. Project; Public code

Paulo's recollection ties a set of tools to his father's work and a wearer's invitation. Elsewhere in this history, a motor repeats a movement, a design travels by mail or an artist writes code. The accounts also turn on who teaches a practice, how work is shared and who may receive a particular kind of tattoo.
