Custom Printed PE Bags: What to Approve on an Artwork Proof

Review print orientation, placement, colour and artwork revision on a finished-size drawing before approving a custom printed PE bag.

Gravure printing at Hengyi. Review critical colour and readability on the intended film.

Mark the finished edges

Label the front and back faces, opening, seals, folds and any punched areas. Dimension the artwork from an agreed finished edge. Keep critical copy clear of folds, seals and areas covered during packing. Send the latest bag drawing with the art.

Check how the artwork reads on clear film

View the print against the actual contents or the typical background. Dark products can make dark print difficult to read, and printing on the other face can show through. If a white underprint is proposed, mark its boundaries and review the effect on a physical sample.

Check colour and scanning separately

Supply colour references and identify the elements that matter most. For small text and barcodes, inspect at actual size. If scan performance matters, test with the bag filled and in its normal scanning orientation. A digital proof helps check layout and copy. A physical print check addresses appearance on the intended film.

Lock the artwork version

Approve one dated revision and keep a copy of the matching proof. On repeat orders, identify the previous reference and list changes. Ask whether changes in size, print repeat or colour require revised plates.

What files should I send?

Send the finished drawing, front and back artwork, film finish, colour references, placement dimensions and quantity. Flag any elements that need physical approval.
