Prepress control
Four checks before releasing artwork
Dieline geometry
Verify cut, crease, glue, bleed, safe area, window and finishing layers against the approved physical structure.
Finished dimensions
Record internal and external size, measuring method and acceptable tolerance instead of relying on a photo or nominal size alone.
Artwork ownership
Freeze approved copy, logos, legal marks, languages and version responsibility before output; production checks do not replace content approval.
Proof purpose
State whether the proof approves structure, layout, colour direction, material or finished process because one proof rarely confirms everything.
Execution method
Four actions from RFQ to production
Use the production dieline
Place artwork only after the final structure and dimensions are confirmed.
Create a preflight report
Flag missing fonts, low-resolution images, colour spaces, overprint and finishing layers.
Approve the right proof
Match proof type to the question being approved: content, structure, colour or finish.
Archive the released package
Keep the final PDF, source assets, version record and approval together.
FAQ
Questions buyers often ask
How should a packaging dieline be checked before printing?
Check scale, panels, cut and crease rules, glue zones, grain direction, bleed, safe areas and process layers against a physical structural sample.
What should be written in the specification?
At minimum, define Dieline geometry, Finished dimensions, Artwork ownership, Proof purpose, then link quantity, sample, timing, inspection and the approved revision.
Is a physical sample needed?
A decision involving structure, material, colour, finish, assembly or use performance normally needs a physical sample matched to that question; a screen proof cannot approve everything.
Can the previous standard be reused for a repeat order?
Reuse a controlled standard only when files, material, structure, supply chain and use conditions remain unchanged. Record every change and decide whether resampling or reapproval is required.
