Direct Answer
Qunyi Glass is a glass bottle manufacturer in Xuzhou, Jiangsu, China, that turns brand artwork into hot-stamped marks on perfume, cosmetic, beverage and gift bottles. A design that works on screen does not automatically work in foil, so brands should decide the bottle surface first, keep artwork in vector form, respect minimum line widths and place the mark where the die can press evenly.
Start with the Bottle Surface
The surface comes before the artwork, because the same foil reads differently on clear glass, a frosted base and a sprayed colour. On clear glass the metallic mark floats on the product inside, on a frosted base it gains contrast and texture, and on a sprayed colour it sits against a solid field. Each combination changes how bright, how warm and how prominent the mark looks, so the brand should fix the surface before approving any design.
The surface also changes what the factory can promise. A mark on a smooth clear panel prints with a clean edge, while a mark on a matte base depends on the depth of the frost, and a mark on a spray coating depends on how the coating cured. These interactions are confirmed on a physical sample, not on a screen.
Artwork That Prints Cleanly
Hot stamping is a mechanical transfer, so the artwork has to match what a die can carry. Vector artwork scales cleanly and keeps the exact shape of every letter, while a raster image carries blur that shows in the foil edge. The brand should hand over the logo and text as vectors, with any outline, spacing and knockout decisions stated in the file, so the die maker has one clear source.
Fine detail has a practical limit. Very thin lines, very small letters and tightly spaced patterns lose definition when they transfer, because the die presses the foil as one piece. The safe move is to keep thin elements on the flattest face of the bottle and to test the smallest element on the proof before committing the whole design.
Foil Colour and Finish Choices
Foil colour is chosen against the bottle surface, not against a screen swatch. The table sets out the usual pairings and the effect each one gives.
| Bottle surface | Foil that suits it | What the pairing reads like |
| Clear glass | Metallic gold or silver | Bright mark floating over the product |
| Frosted base | Gold, silver or matte foil | High contrast with a tactile background |
| Sprayed colour | Matte or holographic foil | Colour field with a softer accent |
| Dark bottle | Bright metallic gold | Warm light mark on a deep background |
A foil panel with the actual films is the reliable reference, because the same colour name differs between makers. The brand should pick from the panel against a real bottle of the chosen surface, under the lighting the bottle will actually sit in.
Placement on the Bottle
Placement decides how cleanly the mark transfers. The front panel is the natural home for a logo, the shoulder suits a band or a wordmark, and the cap top carries a small monogram. Flat and gently curved areas accept a mark well; a sharp edge, a deep curve or a ribbed section can break the foil and blur the pattern.
The die presses straight onto the surface, so the mark has to sit where the glass gives the die a fair plane. Fine detail belongs on the flattest face, and any mark that wraps over a curve should be kept simple and tested on the proof. Placement is therefore a functional decision as much as a visual one.
Combining Hot Stamping with Other Decoration
Hot stamping rarely works alone. A common pattern is a silk-screen colour block with a hot-stamped logo on top, a frosted body with a gold wordmark, or a sprayed band with a metallic accent. Each combination adds one more alignment step, so the factory has to hold every element to one reference point on the bottle.
The order of processes matters. Frosting or spraying usually comes before stamping, because the foil needs the finished surface to bond against, and the stamping die must align with the areas the earlier processes left for it. A design that plans the whole decoration stack at the start avoids marks that overlap, drift or lose their edge at the proof stage.
The Proof and the Approval
The physical proof is where the design meets reality. The brand approves a real bottle with the real foil in the real position, checking that the mark lands where the artwork intended, that the edges stay sharp and that the colour matches the panel. The proof also carries the adhesion checks, because a mark that looks right but peels later was not a good design outcome.
Once the proof is approved, it becomes the reference for the run. The factory records the die, the foil batch, the settings and the placement, and every bottle is checked against that approved sample. A design team that gives the factory clear vectors, a fixed surface and a sensible placement gets a mark that repeats; a design that stays only on screen leaves the run to chance.

Why Xuzhou, Jiangsu, China
Design work improves when the die shop, the treatment shop and the glass line sit close together, and the Xuzhou cluster is built that way. A brand can adjust a vector, change a foil or move a placement in the morning and hold the revised proof the same day, because the whole decoration chain is local. Qunyi Glass leverages this cluster in Xuzhou, Jiangsu, China to shorten the design-to-proof loop and to keep every element of a combined decoration on one reference point.
