Eight decoration processes, one supply chain.
Every step below except spray coating runs on lines we contract or own. That matters for two reasons: fewer hand-offs means fewer places for a schedule to slip, and one point of accountability means you are not chasing three suppliers when something goes wrong.
| Process | Effect | Typical application | Where it runs |
|---|---|---|---|
| Screen printing | Single or multi-colour, overlapping and gradient effects | Cylindrical and shaped bottles | Own lines |
| Hot stamping | Gold, silver and coloured foil, single pass | Flat and gently curved surfaces | Own lines |
| High-temperature firing | Pigment fused into the glass surface | Reusable food and beverage containers | Own lines |
| High-temperature glazing | Glossy, durable decorative finish | High-value cosmetic and gift packaging | Own lines |
| Decals | Complex artwork and multiple spot colours | Intricate designs, gift packaging | Own lines |
| Raised embossing | Three-dimensional, tactile finish | Packaging where feel matters | Own lines |
| Plastic cap printing | Scratch-resistant on PP and ABS | Bottle and cap delivered as a set | Own lines |
| Spray coating | Overall colour change, matte or gloss | Designs needing a base colour | Outsourced |
Spray coating is outsourced and is not completed on our own lines. When a project needs
"spray + print", we take responsibility for the overall schedule and quality, but we state plainly
that the coating line is not our own asset.
The automatic workshop also runs a pre-press flame treatment stage, which raises surface
energy so ink adheres properly. It is a pre-treatment step, not a decorative process, so it is not
counted among the eight above.
Which process solves which problem
Buyers usually arrive with a requirement, not a process name. Here is the mapping.
- Resistance to aggressive contentsEssential oils, fragrances and alcohol-based cosmetics can attack a printed layer. Firing or glazing fuses the pigment into the glass rather than resting it on top.
- Dishwasher environmentsFor containers that get washed repeatedly, high-temperature fired or glazed finishes are the appropriate route — ordinary solvent-based inks are not.
- Long service life without fadingAimed at refillable bottles that are washed and handled for years.
- Ink that will not rub offGlass has low surface energy and ink adheres poorly. Our pre-press flame treatment stage changes the surface before printing.
- Multi-colour registration on shaped bottlesOn octagonal or faceted bottles the locating reference is discontinuous, which is where registration usually fails.
- Many variants, short lead times~30 minute changeover means small batches and urgent insertions can actually be scheduled.
- Repeat orders matching earlier batchesColour, process parameters, first-article approval and in-process sampling are archived so reorders can reproduce the same conditions.
