Start with one version of the facts
The handoff should identify the product, pack dimensions, intended material and revision of the structure. If a value is provisional, say so. A supplier should not have to infer which of several similar files contains the current dimensions.
Keep artwork and specifications connected
Use matching revision references for the flat artwork, visual proof and material notes. Explain any special finishes or separate components. If a render is only illustrative, keep that distinction clear in the project record so it is not mistaken for a technical drawing.
Ask for a defined next step
A quotation, a blank sample, a printed proof and a production approval are different requests. Name the one you need. Include the quantity and delivery assumptions relevant to that request, and ask the supplier which missing details would change the result.
Close the feedback loop
Keep comments beside the relevant panel or specification, then issue a revised version with the resolved changes listed. Avoid silently overwriting the file that the supplier has already reviewed. A short change log makes it easier for everyone to see what needs another check.
Use the checklist below
Mark off the items as a local review aid. The checklist does not send data anywhere and it does not replace your supplier’s proofing process. Its job is to make the next conversation more complete.
