Fine, repeatable print for demanding graphics.
Process, selection & quality control
Process selection starts with the product, artwork, film, packing equipment and real run length. Final specifications follow sampling and line trials.
- Define color, seal and appearance criteria
- Control artwork version and structure
- Trial with the real product and machine

Doctor blade
The blade removes surface ink so transfer comes from the cells; setup and maintenance affect consistency.
Practical comparison
| Criterion | Flexo | Rotogravure |
|---|---|---|
| Ink transfer | Photopolymer plate & anilox | Engraved cylinder cells |
| Preparation | Plate and impression setup | Cylinder preparation per design |
| Economic fit | Depends on artwork, run and repeats | Depends on run, repeats and cylinder cost |
Advantages
Manufacturability, quality and cost improve when the process matches the real brief.
Limitations
No process or structure is best for every product; machine, material, run and market limits must be documented.
