When a filled word develops gaps, reduce the problem to one letter and then one path. Compare the source geometry, grouping and physical result in that order. This branch test prevents several unrelated timing or fill changes from hiding an open contour, duplicate object or overlap in the artwork.
Current engraving troubleshooting asks whether missing fill follows geometry, grouping or the physical mark; a one-path control gives the branches different evidence. Current demand source. The external reference establishes a current decision or failure pattern, not a machine specification, compatible-material list or promised result.
Audit the source before touching process values
Duplicate the released file, outline one affected letter and inspect for open paths, doubled contours, self-intersections and hidden objects. Preserve the original for comparison. If the gap is visible in a filled vector preview, it is a geometry issue and should be corrected before any laser test.
Build a one-path control
Export a simple closed shape at the same physical scale and place it near the affected zone on an identified sample. If the control fills but the letter does not, return to the complex path. If both show the same gap, investigate position, coating response and the documented configuration without changing multiple inputs.
Reconstruct the word in stages
Add letters back one at a time, keeping the accepted path intact. Save the first stage at which the gap returns. That file becomes evidence for support or further diagnosis, while a full-word retry would only show that the problem still exists.
Evidence table for multi-path letter fill gaps
| Branch | Control evidence | Next action |
|---|---|---|
| Artwork | gap appears in vector fill | repair geometry |
| Grouping | single path passes, group fails | rebuild combination |
| Position | same path changes by location | hold and inspect setup |
| Surface | lot or coating changes | requalify blank |
Release rule for multi-path letter fill gaps
Release the lettering file after every closed path fills on the final-size physical proof and the saved export matches the approved revision. Keep the failed stage instead of deleting the evidence.
TYVOK P2 boundary for multi-path letter fill gaps
P2 does not automatically repair customer vectors or certify typography. Verify the live software and import path for the current configuration. Use an identified compatible blank, active supervision, effective fume control and a ready stop procedure; unexpected motion or surface behavior ends the test. Review the current TYVOK P2 page before purchase or use.

Buyer questions about multi-path letter fill gaps
Does increasing power close a vector gap?
It may widen a mark but cannot repair an open or malformed source path.
Why test one letter instead of the word?
It reduces the number of contours and makes the first failing combination observable.
Can the corrected file move to another coating?
The geometry can transfer, but the physical result still needs a new material proof.
