What is a proof?

A proof is an agreement between you and Lumi confirming the design and specifications of your item before it enters production. If anything is missing or not correctly represented on the proof, let us know, otherwise you may not be eligible for a refund/remake if the product does not meet your expectations.

Proofs at Lumi are always provided digitally. The digital proof looks similar to a dieline, but is formatted for manufacturing. Manufacturing will not begin until you approve your proof. All lead times on the Lumi website account for a 24-hour approval process. If it takes longer than 24 hours to approve your proof, your estimated delivery date may be delayed.
