Envelope Manufacturing Tolerances

Normal machinery variances in the envelope manufacturing industry are +/- 2mm. This occurs because as machinery runs, it heats up, and metal expands.

In addition, normal wear in cylinders and bearings can cause subtle variations in cutting location and folding scores. As a result, your envelope may be ever so slightly larger or slightly smaller than you ordered.
