I don’t understand all the annotations on the prepress print you sent me.

Not all of this information will be directly relevant to you (the reference marks for our cutting machines, for example), but you might find some features useful for monitoring production, such as the total quantity (TQ), the dimensions of your components or the quantity indications on the printing plates (indicated by a red “by X”) etc. We therefore suggest that you check your prepress proofs very carefully, as this will be what we will finally print. If there is a mistake (because these can happen!) on the prepress proof and you give us confirmation without having noticed it, Azao Games cannot be held responsible.
