Tumbler engraving is steady work for many laser shops, but wrapping flat artwork around a cylinder trips up beginners every time. Most failed wraps trace back to one of three causes: a wrong circumference, a seam in the wrong place, or artwork prepared for a screen instead of a coating. Work through the steps below in order.
Step 1: Measure the blank, not the catalog
Measure the diameter where the artwork will sit and calculate the circumference (π × diameter) so your wrap fits. A 76 mm diameter gives 3.14159 × 76 ≈ 238.8 mm of wrap width. Then measure the engravable height in mm, between the lid line, any handle and the point where the base starts to taper. Measure the cup in your hand rather than trusting the published size: a 1–2 mm difference is common, and on a full wrap that error appears as a gap or an overlap at the seam. On a tapered cup, measure the top and bottom diameter of the engraving zone separately.
Step 2: Lay out the wrap in Wrap Studio
Open the Reticle Red Wrap Studio tool and pick a YETI, Stanley or generic preset, or enter your own diameter and height. Tapered items take a top and a bottom diameter. It calculates the circumference, lays the artwork out as a flat wrap and shows a seam preview of where the two edges meet. Export SVG or PNG and import it into your control software's rotary mode, such as LightBurn. Wrap Studio is free, needs no account, and the same measurements work for bottles, candle jars, pipes and other cylinders.
Step 3: Put the seam and the handle somewhere quiet
Decide where the seam will sit before you place any artwork. On a handled tumbler, keep the seam and every important element out of the zone the handle blocks. For an all-over pattern, check in the seam preview that the left and right edges continue into each other; for a single logo or name, center it on the face opposite the seam. The free rotary centerline template helps you check orientation and placement before export.
Step 4: Prepare the artwork for the coating
Common mistake: Applying your image at 72 DPI then wondering why it looks pixelated. Always export at 300+ DPI or use Image Lab → Vectorize for professional SVG vector paths.
Pro tip: Use Image Lab → the Prep tab → the "Anodized Aluminum" material preset before sending to your laser to boost contrast and remove grey midtones that won't engrave cleanly. The preset targets 300 DPI and inverts the image, which suits a dark coating where the laser exposes brighter metal; check the preview before using it on a light-colored coating.
Step 5: Prove the burn on the rotary
Configure your roller or chuck rotary in the control software, frame a small design, and confirm the imported width matches the measured circumference before committing to a full wrap. These bundled starting points come from the Parameters Library:
| Surface | Laser | Power | Speed | Line interval |
|---|---|---|---|---|
| Powder-coated tumbler | 50W fiber | 80% | 1500 mm/s | 0.025 mm |
| Stainless bottle or tumbler | 30W fiber | 80% | 1000 mm/s | 0.025 mm |
| Bare stainless (anneal mark) | 20W diode | 45% | 80 mm/s | 0.08 mm |
| Glass tumbler | 60W CO2 | 18% | 200 mm/s | 0.1 mm |
Treat each row as the center of a test grid, not a recipe: none has been independently verified, and the coating, blank supplier, lens and rotary all move the result. The diode record notes that annealing stainless with a diode is less consistent than a MOPA fiber and recommends CerMark for reliable marks, and the glass record uses masking tape to reduce chipping. Start a small test patch at the base of the tumbler where it won't show, or on a matching blank. Inspect contrast, coating removal, the first and last columns and the join, then save the artwork dimensions with the rotary and laser settings that produced the accepted piece. More material records are grouped under laser settings by material.
Frequently asked questions: Image Processing
What laser settings should I use to engrave a stainless steel tumbler?
It depends on the laser and the surface, so treat any published number as the center of a test grid. The Parameters Library's bundled baselines start a 30W fiber on stainless bottles and tumblers at 80% power and 1000 mm/s, a 50W fiber on powder-coated tumblers at 80% and 1500 mm/s, and a 20W diode anneal mark on bare stainless at 45% and 80 mm/s; the diode record notes that result is less consistent than a MOPA fiber and recommends CerMark for reliable marks. Use the rotary attachment and run a small test patch at the base of the tumbler before committing to the full wrap. Always export your artwork at 300+ DPI to avoid pixelation — use an SVG from Image Lab → Vectorize for the sharpest result.
How do I calculate the correct wrap dimensions for tumbler engraving?
Measure your tumbler's diameter and calculate the circumference using the formula: circumference = π × diameter (approximately 3.14159 × diameter in mm). That gives you the horizontal wrap width. Measure the engravable height of the tumbler for the vertical dimension. Enter both values into the Reticle Red Wrap Studio tool and your artwork will auto-fit to a perfectly sized rectangular wrap.
Why does my tumbler engraving look pixelated or blurry?
Pixelated tumbler engravings are almost always caused by low-resolution artwork. Common causes: exporting the design at 72 DPI (screen resolution) instead of 300+ DPI, or using a JPEG or compressed PNG with compression artifacts. Fix this by using vector artwork (SVG) from Image Lab → Vectorize, or by re-exporting your design at 300 DPI minimum before sending to your laser.
