HectoInk
For working tattoo artists

Photo in. Stencil out.
Exactly the size you set.

Upload a client's photo or your own artwork and get back a clean stencil that prints at true size on your thermal printer: tiled across Letter or A4 sheets with registration marks and a 1-inch calibration square, so what you print is what lands on skin.

The last step is the one that matters: a stencil that comes off the printer at the size you asked for.

Starting presets, not lab calibrations: they nudge line density and weight for common printer and paper combos. We tune them with working artists' feedback.

Four steps, no tracing table

The hour you spend hand-tracing a reference is an hour you are not tattooing. HectoInk does the tracing and the sizing; you keep the judgment calls.

01

Upload

A client photo, a flash scan, a Procreate export, any PNG, JPG or WEBP.

02

Dial the lines

Three modes (Outline, Linework, Bold), a detail slider and a line-weight slider. Preview updates before you commit.

03

Set the size

Tell it the width in inches. The pack is built at that exact size at 300 DPI, tiled if it outgrows one sheet.

04

Print and transfer

Print at 100%, check the calibration square, overlap the tiles on the crosses, run it through your thermal printer.

Built for the printer you already own

Purple tattoo stencil applied on a forearm

True size, verified on paper

Most stencil tools export a picture and leave the sizing to you. HectoInk exports a print: exact inches, 0.5 inch tile overlap, registration crosses, and a 1-inch square on the first tile that exposes any printer rescaling before the stencil touches skin.

Lines that survive transfer

Detail and line weight are separate controls because they fail differently: too much detail clogs on skin, too little loses the design. The run sheet warns you when a design is too fine for the size you picked, before you waste a sheet.

Every format in one pack

Tiled print PDF for the thermal printer, an exact-size PNG for your tablet, and an SVG if you want to push lines around in a vector editor. One upload, one download, no re-exporting.

No iPad app, no desktop install, nothing between you and the chair. It works on the shop computer, your phone, or the front-desk PC, and your images are converted, not stored.

Real output, not a mockup

Questions from the chair

Will it work with my thermal printer?

If your printer takes Letter or A4 stencil paper, yes. The PDF is built at 300 DPI on that exact sheet size. Print at 100% scale with fit-to-page off, then measure the calibration square on tile 1: if it is exactly 1 inch, every line on the sheet is true size.

What photos work best?

Clear, well-lit references with real contrast. Linework mode handles portraits and realism references; Outline is best for artwork and flash; Bold is for simple, graphic designs that need to read from across the room. Flat, even lighting beats a dramatic photo every time.

Can it do realism and portraits?

It extracts the lines a realism stencil actually needs: the map, not the shading. Heavy shading does not transfer as a stencil, so the converter keeps structure and leaves value work to you, and the run sheet flags designs whose detail is too fine for the size you set.

Why not just trace in Procreate?

You can, and many artists do. It costs you the tracing time on every client, plus manual sizing and tiling for anything bigger than one sheet. HectoInk exists for the part of the job that is mechanical; the drawing judgment stays yours.

Do you keep my images?

No. Images are converted in the request and not stored. Client references are your clients' business, not ours.

Can I use stencils for paying client work?

Yes. Anything you make with HectoInk is yours to tattoo, on any plan including Single.
