How We Print Your Design on a Tumbler

Your design is printed onto a curved stainless steel surface. Two things follow from that: the print area is fixed for each cup model, and artwork that looks flat on screen can behave differently once it wraps around a curve.

This guide covers what to prepare before uploading, and what to check before you approve the layout.

What file format should I upload?

Upload a JPG, PNG or WebP file. The maximum file size is 5 MB.

Higher resolution is always better, because a print is larger than a phone screen. A good working target is 1500 pixels on the longest side, or higher if your original file supports it.

How large should my image be?

Keep the most important part of your design inside the center of the image. The middle of a tumbler faces the viewer most directly, and the edges wrap around the curve where they are hardest to judge.

A practical approach:

• Square or portrait images work best for most cup models.
• Leave a small margin around your subject rather than filling the frame edge to edge.
• Avoid placing text right at the edge of the image.

Will my photo print the same colors I see on screen?

Close enough for most images, but not pixel-identical. The print process reproduces your file's colors on a physical surface, so very bright neon tones and very dark shadows can shift slightly.

Two habits help:

1. Export as sRGB, which is the standard for web images and what our printing pipeline expects.
2. Avoid images that rely on very subtle color differences to read correctly, such as a pale beige subject against a pale grey background.

How do I avoid a print that looks stretched or cut off?

Because the surface is curved, we scale your image to fit a fixed print area and keep the proportions you supplied. The most common problems are not stretching — they are cropping and detail loss.

What to avoid:

• Very wide panoramic images (they must be reduced a lot to fit, which softens fine detail)
• Screenshots of photos taken on another device (they compress and lose quality)
• Long thin text banners running edge to edge

What works well: a single clear subject, centered, with space around it.

Can I adjust the size and position of my design?

Yes. The personalization studio gives you controls for image size and horizontal position. Use them to place the design where you want it on the cup before you approve.

We recommend adjusting until the subject sits centered and the print area looks balanced from the front view.

What happens before production?

You approve the layout first. Nothing enters production on a guess. Once you approve, the design and your chosen options are handed to the nearer factory for printing and packing.

What if my design has a problem after it prints?

If the finished item arrives with a clear production defect — for example, a visible print failure or a damaged item — we will replace it or refund it. See our returns and replacements policy for the full list of covered situations and how to start a request.

Who fixes an incomplete design across the seam?

Our production team prepares the production artwork so the wrap seam and print position stay consistent. If your design does not cover the full printable area, the team handles the seam transition so the result looks intentional rather than cut off.
