Should graphics meant to be wrapped around a cylinder be stretched to compensate?
I am designing a 1:1 height-to-width circular graphic to be printed on a mug. However, when printed on the mug, the graphic looks noticeably squished and oval-shaped as a result of the mug's curvature. This applies to any situation where a graphic is wrapped around part of a cylindrical shape.
Should I squish the design out wider to counter this skinny appearance or should I should leave it as is? Which is good practice? What is usually done in this situation?
For a logo on a cylindrical mug? No you should not distort.
That would only make your circle wobbly from a slightly different angle. In fact, from another angle it would look like a blob. We have no problem accepting this copyright C as a circle. If it was, from this angle, a perfect circle, our minds would be a little confused.
It looks wrong, the circle is kind of "falling out" or "off":
The mug is a 3D object, and will therefore never be 2D. Our brains are masters of navigating 3D space, and if you tinkered with your circle logo, you will only create Dali-ish melting clock.
Consider streetart. They are heavily distorted to compensate for angle. That is why they only work when viewed from one specific angle.
