What it does
Packwire's browser configurator combines box dimensions, material choices and artwork with open and closed 3D views. Text, panel colours and uploaded files can be arranged while the production estimate changes. Physical orders go through a separate proof review.
Set the mailer's interior length, width and depth in inches, then choose its material and quantity. Upload JPG, PNG, WebP or PDF artwork up to 10 MB, add text and choose panel colours. Open and closed views reveal the lid and interior as well as the outside.
Ink coverage affects the price. Any artwork inside the mailer makes it a two-sided print job, even if the inside design is small. Save a named design to a free account to return to it later.
Packwire recommends CMYK print colours, raster images at least 300 dots per inch and a quarter-inch bleed beyond each artwork edge. Packwire sends a 2D production proof before manufacturing, and proof revisions are free. The proof is where the final layout and orientation are approved.
The visual drag-and-drop configurator may not be fully accessible, so Packwire offers design assistance. Its terms leave customer artwork with the customer and permit showcasing completed work unless the customer opts out. A designer submitting a client's artwork needs the owner's permission.
