Focus 1Preserve editable geometry
Provide vector source when available, with text outlined or fonts supplied under a usable license. Keep layers named for color, cut edge, and any raised or recessed zones. Also include a simple PDF or image preview so the intended appearance is visible without editing software.
Focus 2State scale and tolerances
Specify finished width and height in physical units, plus placement and viewing distance. Mark details that are essential to recognition. Ask the supplier to flag any feature that may need simplification rather than silently changing it.
Focus 3Track approvals
Give every file a revision identifier and one contact who can approve changes. Record the approved proof beside the actual sample and quotation. When color or size changes, treat the result as a new variant instead of assuming the old approval applies.
