A stencil that prints at the wrong size is worse than no stencil. In HectoInk you set one number, the design width in inches, and every download is built to that size: the tiled print PDF, the 300 DPI PNG, and the SVG. This guide covers how to choose a width and how to confirm your printer is not quietly rescaling it.
Free preview. No account. Your image is converted, not stored.
Starting presets, not lab calibrations: they nudge line density and weight for common printer and paper combos. We tune them with working artists' feedback.
Every pack: true-size tiled print PDF, exact-size PNG at 300 DPI, SVG, and a run sheet with print instructions.
Measure the body area with a tape or a paper template, then set the design width a little inside that measurement so the stencil sits flat without wrapping over a curve. The preview shows the width you set, and the download matches it exactly.
Print the PDF at 100 percent scale with fit to page turned off, then measure the 1-inch calibration square in the corner. If it measures one inch, the stencil is exact. If it does not, your printer driver is scaling, which is the most common cause of wrong size stencils.
The PNG is rendered at 300 dots per inch at the exact width you set. A 4-inch wide design downloads as a 1200 pixel wide PNG, so it prints sharp at 4 inches and carries the size in the file itself.
