Before engraving a customer card batch, compare several hatch directions on sacrificial positions of the exact identified coating. Keep geometry, size, focus method and inspection light fixed. The goal is not to discover a universal preset; it is to choose the direction that gives the most acceptable physical fill for that one card lot.
Material-test arrays are a current support pattern for replacing guessed presets with controlled physical evidence. Current demand source. Use the linked discussion or support page as evidence of the buyer problem, while treating the live TYVOK page as the separate source for machine facts.
Create a direction-only test strip
Use the same small filled shape several times and change only hatch direction. Label every swatch in the artwork and on the physical card. Do not change speed, power, line interval and direction together, because the winning swatch would no longer reveal which variable mattered.
Inspect fill and edge behavior separately
Judge center uniformity, edge sharpness and any visible directional texture under fixed lighting. A darker center can still be rejected if the edge grows beyond the approved logo. Photograph the cooled card at one camera angle and retain a reference swatch for the lot.
Transfer cautiously to finished artwork
Run one final-size logo on a disposable or approved sample before using sellable stock. Thin counters, letters and borders can react differently from the solid test square. Release the batch only when the complex proof matches the written acceptance rule, not merely the best-looking isolated swatch.
Evidence table for coated-card hatch direction
| Controlled item | Keep fixed | Reject when |
|---|---|---|
| Card | supplier SKU and lot | identity is missing |
| Test geometry | size and position | swatches differ structurally |
| Inspection | light and camera angle | comparisons use mixed conditions |
| Final proof | released customer artwork | edges or counters fail |
Release rule for coated-card hatch direction
Record the selected hatch direction beside the card lot and final proof. A new coating, supplier, lot, artwork scale or head configuration reopens qualification; do not silently reuse the old choice.
TYVOK P2 boundary for coated-card hatch direction
P2 uses a blue semiconductor source, so the observed response may come from a compatible coating rather than the underlying metal. Keep the operation attended, use current ventilation and fire precautions, and stop for unexpected flame, persistent smoke, abnormal odor or machine behavior. The test does not promise permanence or suitability for every card. Review the current TYVOK P2 page before purchase or use.

Buyer questions about coated-card hatch direction
Should I test on the center of a finished card?
Prefer a sacrificial location or sample so the qualification does not consume the sellable center.
Can hatch direction fix weak source artwork?
No. Confirm that the vector paths and final-size geometry are valid first.
May I reuse the result on another black card?
Only after the new card identity and coating are requalified.
