Single-Line Text and Fonts for Pen Plotters

Create stroke-based SVG lettering with Plotter Text, choose a single-line font, and check character coverage, scale, and exported paths before plotting.

Single-line fonts versus outlined text

Most ordinary typefaces describe the filled outline around a letter. Converting them to paths produces that outline, so a pen may draw both sides of each stroke. A single-line font describes strokes for the pen to follow instead.

The letters R and a drawn as plotter paths in Georgia and in Hershey Sans 1-stroke, with every vertex marked
The same two letters as the paths a plotter would follow. Georgia’s outline needs 4 closed contours with 141 anchor points and 160 curve handles, and the pen traces both edges of every stroke. Hershey Sans 1-stroke needs 5 open strokes through 30 vertices. Generated from the real font files. Download SVG.

“Single-line” does not mean every letter is one uninterrupted path. A letter can contain several strokes and pen lifts, and some decorative fonts use multiple strokes deliberately. Choose a font by inspecting its paths and how they suit your pen.

Plotter Text turns bundled stroke fonts into SVG paths. It can place lettering on a blank canvas or over a background SVG. The downloaded SVG is artwork, not machine-specific G-code.

Create and position your lettering

  1. Open Plotter Text. Select a text layer, or add one using the layer controls.
  2. Replace the layer’s text with PLOT 123. Use this short sample first so missing characters and spacing are easy to notice.
  3. Choose Hershey Sans 1-stroke in the Single-line font picker. Wait for the font to finish loading. On a small screen the font picker is a select menu.
  4. Adjust Font size and Character spacing. Use Line height for multiline text and Alignment for its layout.
  5. Move the text on the canvas and use Rotation when needed. Keep the whole word inside the page. If you have several layers, select the one you intend to change.

Use Stroke Font Studio when you want to work on the font itself. Plotter Text is the place to arrange lettering for a drawing.

Export paths and check the result

Turn on Export text only to omit the background artwork, then click Download SVG. Turn it off when the background SVG is part of the drawing you want to keep. Preserve a separate copy of any original artwork.

PLOT 123 drawn with single-line vector lettering
PLOT 123 exported from Plotter Text with the bundled Hershey Sans 1-stroke font. Download SVG.

Open the download in a vector editor or plotting software. Confirm that the letters are paths, that all characters are present, and that the layout fits the intended physical page. Set the final scale in your receiving software and inspect the toolpath before drawing.

Stroke width changes the displayed line thickness. It does not change your physical pen tip or automatically generate parallel passes to fill a thick letter. A plotter normally follows the path centerline. Test a short line of text with your actual pen and paper before a larger job.

Character coverage and font limitations

Character coverage varies by font. Check punctuation, accents, symbols, and every language you need in the preview and the exported file. Do not assume that every bundled font supports the same characters or that unsupported characters will be replaced correctly.

The specimen sheet below shows every bundled Latin font drawing the same pangram, so you can compare weight, width and character before choosing. It was generated from the font files themselves, and the sheet is itself a plottable SVG: the labels are set in Hershey Sans 1-stroke. The symbol, ornament and non-Latin fonts (Hershey Astrology, Cyrillic, Greek, Japanese, Markers, Math, Meteorology, Music and Symbolic, and Relief Ornament) are omitted because the phrase has no meaning in them.

Try another font if a character is missing. Font size and spacing affect legibility, especially for small letters and wider pens. Increasing displayed stroke width is not a substitute for choosing a suitable font.

The tool also offers Import font… for supported custom fonts. Begin with a bundled font for a reproducible result, and follow the import dialog’s supported-format instructions for custom work. Consult About this font, where available, for attribution and licensing information.

Troubleshoot before sending to the machine

  • Letters are drawn twice around their edges: check whether you used an outlined typeface rather than a stroke font.
  • Letters overlap: adjust character spacing and inspect the selected font at the final size.
  • Text is absent from the download: wait for the font to load, check the layer content, and verify that its paths lie on the page.
  • A background is unexpectedly included: enable Export text only and download again.
  • The drawing is too large or small: inspect units and dimensions in your machine software before plotting.

Find other artwork tools in the SVG generators directory and compatible sending software in plotter control tools. If lettering extends outside your composition, follow the SVG cropping guide. The sample here has been checked as a browser export; no physical machine result is claimed.
