What is Wrapsmith?

Wrapsmith is a sublimation design and mockup app built around one promise: the print comes out the right size. Every template canvas matches the real physical wrap area of the blank — mugs, skinny tumblers, larger tumblers, and shirt fronts — with bleed and safe-zone guides drawn in, plus custom dimension entry for anything else on your shelf.

Import a photo, fit it to the safe zone, add a caption, and see the design genuinely wrapped around the product before you commit ink. The mockup uses a real cylindrical projection with curvature shading, so what curves on screen is what curves on the tumbler.

When the design fits, export a press-ready PNG or PDF at true print size and DPI, with a mirror toggle for sublimation transfer. Projects are saved locally and the whole app works offline — designed for the crafter at a kitchen heat press, not a render lab.

Features

True-size templates

Preset canvases match the real wrap area of common blanks — 11 oz and 15 oz mugs, 20 oz skinny and 30 oz tumblers, and shirt fronts — or enter custom dimensions.

Bleed and safe-zone guides

Guides show exactly where the design must sit, and a clear confirmation appears when everything stays inside the safe zone.

On-product mockup

Your artwork is wrapped onto the tumbler or mug with a real cylindrical projection, so you see the curved result before pressing.

Photo import and layout

Bring in a photo from your library, then place, scale, and fit it to the wrap. Add a text caption and manage layers with a tap.

Press-ready export

Export PNG or PDF at true print size and DPI, with a mirror-for-sublimation toggle, ready to send to your printer.

Offline projects

Designs are stored on your device and every feature works without a connection — no account needed to open the editor.

How it works

Pick your blank

Choose a preset — mug, skinny tumbler, 30 oz, shirt front — or enter custom wrap dimensions.

Place your artwork

Import a photo, scale and position it inside the bleed and safe-zone guides, and add a caption if you want one.

Check the mockup

See the design wrapped around the product with real curvature before you commit transfer paper.

Export press-ready

Save a PNG or PDF at exact print size and DPI, mirrored for sublimation if your workflow needs it.

Frequently Asked Questions

Why does my sublimation print come out the wrong size?

Usually the design file was not created at the blank's true physical dimensions, or the print dialog rescaled it to fit the page. The fix is to design on a canvas that matches the real wrap area and export at exact size and DPI with scaling turned off when printing. Wrapsmith's templates are dimension-true and its exports carry the correct physical size, so the file that leaves the app is the size that prints.

What size is a 20 oz skinny tumbler wrap?

Most straight-walled 20 oz skinny tumblers take a full wrap of roughly 9.5 inches around by a little over 8 inches tall, but blanks vary by supplier, so it pays to measure yours. Wrapsmith ships a 20 oz skinny preset with bleed and safe-zone guides, and custom dimension entry covers any blank that differs.

Is there an app to design sublimation prints on iPhone?

Yes. Wrapsmith runs the whole flow on iPhone and iPad: pick a blank preset, import your artwork, fit it inside the guides, preview it wrapped on the product, and export a press-ready file. No desktop software is required, and the app works offline.

Do you have to mirror an image for sublimation?

In most workflows, yes — sublimation transfers face-down onto the blank, so the print must be a mirror image to read correctly on the finished product. Some printer drivers mirror automatically, so you should flip in exactly one place. Wrapsmith has a mirror-for-sublimation toggle on export, so you control whether the file is flipped.

What DPI should sublimation designs be?

300 DPI at the final physical print size is the usual standard — it keeps text and edges crisp on mugs and tumblers without inflating file sizes. Wrapsmith exports at true print size with the DPI stated, so a wrap that should be 9.5 inches wide leaves the app as exactly that.

What are bleed and safe zones in a tumbler wrap design?

Bleed is extra artwork beyond the trim edge, so slight misalignment on the press never leaves a bare stripe; the safe zone is the inner region where important elements like text must stay. Wrapsmith draws both guides on every template and confirms visually when your design sits correctly inside them.

Can I preview my design on a tumbler before printing?

Yes. Wrapsmith wraps your actual artwork around the product using a per-column cylindrical projection with curvature shading — not a flat sticker overlay. Seeing the curved result first catches placement and scale problems before they cost you a blank and transfer paper.

How do I fit a photo to a tumbler wrap without stretching it?

Scale the photo proportionally until it covers the wrap area, position the subject inside the safe zone, and let the excess run into the bleed rather than squashing the image. Wrapsmith's fit-to-safe-zone control does this in one tap, and the mockup shows how the photo lands once curved around the tumbler.

What file format should I use for sublimation printing?

PNG is the common choice for artwork sent to a sublimation printer, and PDF is useful when a print service expects a fixed-size document. Wrapsmith exports both, at true physical dimensions and stated DPI, with optional mirroring.

Can I make mug wrap templates for 11 oz and 15 oz mugs?

Yes. Wrapsmith includes dimension-true presets for 11 oz and 15 oz mugs alongside the tumbler and shirt-front canvases. Each preset carries the standard wrap area for that blank plus bleed and safe-zone guides.

Do I need an internet connection or account to design?

No. The editor opens without an account, projects are stored on your device, and layout, mockup, and export all work offline — a craft room with weak wifi is not a problem.

Can I design wraps for blanks that aren't in the presets?

Yes. Enter the wrap width and height for any blank and Wrapsmith builds a dimension-true canvas with the same bleed and safe-zone guides, mockup preview, and true-size export as the built-in presets.
