Inkmap Deep Dive: Accurate, Scaled Map Printing on the Web

Reading time: ~6 min

High-quality, to-scale print layouts are traditionally a desktop GIS task. Inkmap brings that capability to the browser by rendering vector tiles and layers into print-ready canvases. TrueGIS leans on the same ideas to give you Scaled Print with predictable output.

What “to scale” means on the web

• Consistent ground resolution for a given scale (e.g., 1:10,000).
• Paper size & orientation determine the map frame.
• DPI affects print sharpness; browsers map CSS pixels to device pixels.

Why this matters

When you’re producing planning maps, route sheets, or field sketches, a printed 1:5,000 has to match reality. Inkmap’s rendering pipeline keeps the math straight so features aren’t stretched or blurry.

How TrueGIS applies these concepts

1. Choose a scale (e.g., 1:5,000, 1:10,000).
2. Pick orientation (Landscape/Portrait).
3. Toggle “Show Print Area” to preview the exact frame.
4. Export via Scaled Print for predictable output.

Best practices

• Prefer vector overlays for crisp lines at any scale.
• Use high-contrast styles; thin strokes often look best in print.
• Preview at the final paper orientation before exporting.
