Before approving acrylic laser-cutting artwork, confirm the real size, cutting contours, engraved areas, hole positions, quantity and revision. For interlocking or fitted parts, ask the fabricator to confirm how the cutting width and actual sheet thickness will be handled, then approve a test piece where fit matters.
This is a final design checklist for physical cut parts. For a general explanation of vector and image formats, use the existing laser artwork file-format guide.
Key Takeaways
- A file that opens correctly can still contain the wrong dimensions or cutting paths.
- Identify cutting, marking and engraving separately in a written legend.
- Approve critical fits using the proposed material and process.
1. Confirm scale with a dimension you can check
Include the intended finished width and height in the message as well as in a dimensioned preview. Ask the fabricator to confirm those measurements after importing the production file.
A hypothetical desk sign might be 180 mm wide and 75 mm high. Put those dimensions beside the preview rather than relying on the file name “small sign.” If the sign fits an existing base, provide the base opening dimensions and explain whether the part should slide freely or lock into place.
Keep the dimensioned preview separate from the cutting geometry unless the supplier asks for a different arrangement. Labels, page borders and dimension arrows are useful for humans but should not accidentally become machine paths. The laser-cutting service page is the starting point for confirming the accepted submission method.
2. Separate cut edges from surface decoration
Provide a clear legend identifying what is cut through and what remains on the surface. Do not assume that a particular line colour or stroke width has the same meaning for every supplier.
For each part, distinguish its outside shape, through-holes, engraved text and any printed artwork. Send a preview showing the expected finished appearance. If the item has a front and back, label both views and identify the viewing side.
Check that the chosen letters are still correct after converting text for production. Pay particular attention to punctuation, accents, business names and characters from different writing systems. Keep an editable original for future revisions, but approve the exact version that will be produced. The artwork preparation guide explains the broader file considerations.
3. Inspect contours, overlaps and loose centres

Check each intended perimeter as geometry, not just as a filled picture. A visually complete shape may contain an open path, duplicated edge or tiny unwanted segment.
The equipment manufacturer's vector-processing documentation describes path editing, contour offsets and cutting inner shapes before outside contours. These are preparation functions, not a promise that every supplied file will be corrected automatically.
Ask whether overlapping paths need removal before submission. The manufacturer's common-line cutting guidance treats overlapping lines explicitly through a software rule. Leave sheet nesting and shared-edge decisions to the fabricator unless they give you a template.
For stencil-style letters, confirm what happens to the centres of letters such as A, B, O and R. If the sign needs those centres to stay connected, the design needs an agreed way to retain them. If the letters mount separately to a backing, confirm the placement method instead. Compare the intended look with the signage catalogue.
4. Agree how holes and slots must fit
Describe the required fit rather than applying a correction borrowed from another job. A loose cable opening, a screw hole and an interlocking slot perform different jobs.
Laser cutting removes material along the cutting path. The equipment documentation includes kerf correction, which compensates for this cutting width. The appropriate adjustment depends on the actual production setup; there is no single correction in this checklist that applies to every thickness and machine.
- State the object, fixing or tab that must pass through each opening.
- Explain whether movement or a tight connection is intended.
- Ask who will apply the final dimensional correction.
- Identify which dimensions need inspection on a test piece.
- Approve a sample before committing to a fitted batch when practical.
If the design will later be bent or bonded, discuss the whole assembly through the acrylic fabrication service, since a correct flat cut is only one stage.
5. Approve one named production revision
Package the production file, preview and written specification together. Use the same revision name across all three, and withdraw superseded versions clearly.
For example, a hypothetical approval message could read: “Approve revision C: 20 clear acrylic panels, finished size 180 × 75 mm, four holes as shown, front engraving only. Material thickness and hole fit as agreed in the quotation. Do not use revision B.” Replace every example detail with the actual order.
Check the quantity per design, not just the total number of pieces. A set of ten different labels is not the same file preparation task as ten identical labels. Confirm protective packing and whether small loose parts will be grouped by set.
Save the approved files for repeat orders. For a new fabrication project, the laser-cutting page gives the relevant service context before you send the final pack.
Frequently asked questions
Is a PDF automatically ready for acrylic laser cutting?
No. A PDF can contain vectors, images or both. Confirm that the actual cutting paths, dimensions and intended operations survive import into the supplier’s production software.
Should I add my own kerf correction?
Only if the fabricator requests it and provides the relevant value and method. Otherwise, give the desired finished dimensions and agree who applies the production correction.
Do I need a sample for every order?
A sample is particularly useful for interlocking parts, unfamiliar artwork or a new assembly. For simple repeat work, ask whether the previously approved specification and process remain unchanged.
