Mug printing, and why the wrap is not a rectangle you can fill
A mug print curves away from the viewer and stops at the handle. What that means for where your design goes, and why centred art often looks off centre.
A mug is the one product where the shape of the object changes the design more than the design does. It is a cylinder, and a cylinder shows you less than half of itself at once.
You are designing a strip, not a panel
The printable area is a band that wraps around the mug and stops short of the handle on both sides. Anything you place is therefore both wider and shorter than it feels in the editor, and only a portion of it faces the person looking.
The curve eats the edges
- The middle of the design faces the viewer and reads normally
- The outer thirds curve away and compress
- Detail near the left and right edges is hard to read from any single angle
Put the thing that matters in the middle third. Decoration can run to the edges; words should not.
Two sides, one design
A wrap covers both the left and right of the handle, which means a right handed person and a left handed person see different halves. Symmetrical designs solve this. So does repeating a small mark rather than placing one large one.
The dashed rectangle in the editor is the real printable band for that mug, measured from the product rather than estimated, so anything inside it prints.
Colour on ceramic
Ceramic is glossy and white, so colours print brighter and more saturated than the same file on cotton. A design tuned for a garment often looks slightly garish on a mug, and toning it down usually improves it.
Text that wraps out of sight
A long phrase across a mug is only ever half readable, because the far half has curved away. If the words matter, set them in two or three short lines in the middle rather than one long line across the whole band.
What survives a dishwasher
Mug prints are hardest hit at the edges, where the curve is tightest and where a stacked mug rubs against its neighbour. Keeping the design away from the extreme left and right of the band is as much about durability as it is about being seen.
