CNC routing starts with geometry the machine can trust. A good production file identifies the actual outline, lettering, scale, depths, layers and finish direction instead of leaving the shop to guess from a small screen image.
Vector artwork is preferred for routed geometry
AI, EPS, SVG and print-ready PDF files can contain true vector paths that scale without changing the shape. That gives us clean geometry for outside profiles, letters, borders and pockets.
A JPG or PNG can still be useful as a reference, but it may need to be redrawn before it becomes production artwork. A photograph alone does not establish exact dimensions or toolpaths.
Convert fonts to outlines before sending final art
Outlined type turns each letter into fixed vector geometry, preventing font substitutions when the file moves between computers. This is especially important for routed copy because a substitute font changes stroke width and spacing.
If editable type is intentionally required, provide the font file only when licensing allows it and identify the exact typeface in the project notes.
Give the drawing at least one reliable dimension
A vector file can be mathematically scalable and still have the wrong intended size. State the finished overall width and height or another dimension that lets us verify scale.
For replacement faces, also include the opening, frame or retainer dimensions that the new piece must physically fit.
Separate routing depths, layers and materials
Show which geometry is through-cut, V-carved, pocketed, raised or applied as a separate component. Color alone is not a reliable routing instruction unless a written legend explains what each color means.
When acrylic, HDU letters, backers or hardware are separate parts, identify those materials and their finished thicknesses on the drawing.
Use controlled color and finish instructions
Screen colors are useful for layout but not for close color matching. Provide a paint manufacturer code, approved swatch or physical reference when the finish has to match a brand standard.
Also identify sheen, metallic effects, distressing or special texture so the quote includes the actual finish process rather than assuming a basic solid color.
Proofing is the last inexpensive place to catch an error
The approval drawing should be checked for spelling, dimensions, proportions, colors, layer locations and mounting details before CNC work begins. Once material is routed, changes usually mean remaking a part.
We build from the approved production information. A clean approval trail protects both the buyer and the shop from changes that were discussed but never incorporated into the final drawing.
Once the proof is approved, that drawing—not an email thread or reference photo—becomes the production reference for machining and finishing.
Frequently asked questions
Can you work from a JPG or PNG logo?
Often, yes, but raster art may require vector redraw before it can be routed accurately.
What vector formats do you prefer?
AI, EPS, SVG and vector PDF are common choices. Clean paths matter more than the file extension alone.
Should fonts be outlined?
Yes for final production artwork. Outlining prevents substitutions and locks the letter geometry.
How do I show routing depths?
Use dimension notes, layer names or a clear written legend that identifies each pocket, V-groove, through-cut and raised component.
Can you match colors from a screen image?
We can approximate them, but a controlled manufacturer color reference is better when matching matters.
Do you send an approval drawing before production?
Yes when the project requires artwork approval. The approved drawing becomes the manufacturing reference.
