Decision framework

Classify the requirement before changing the process

This route covers cylindrical and tapered containers, but those shapes must not be treated as one setup. Selection begins with wall geometry, supported print height, decoration coverage and the way each part is loaded and located.

Classify the side wall

Record the upper and lower diameters at the print band. Equal diameters describe a cylindrical route; different diameters require tapered-fixture and artwork-development checks.

Define the supported print band

Product height is not the same as printable height. Rims, handles, ribs, draft changes and soft wall sections may interrupt support or the roller path.

Choose panel or circumference decoration

A local panel needs a repeatable start datum. A full or near-full wrap also needs seam geometry, artwork pitch and circumferential motion to agree.

Set the loading and output route

Large pails, light cups and containers with handles require different feeding and orientation methods. Automation is chosen after proving that the part can be presented to the fixture consistently.

Field diagnosis

A check sequence from symptom to proof

Observed symptom	Priority judgement	Check first	How to confirm
Seam opens at one end or forms an hourglass	Taper, artwork development, fixture angle or contact-path mismatch	Compare the seam at the top, centre and bottom; confirm both diameters and the supported print height.	Make one geometry correction only and use the direction of seam change to choose the next step.
A band repeats light or dark each revolution	Part roundness, fixture concentricity, wall support or periodic speed variation	Mark the angular position of the defect and see whether it follows the part, fixture or machine.	Reload or rotate the part datum and repeat without changing process energy.
Artwork length or seam position drifts	Surface-speed mismatch, slip, changing film tension or unstable product location	Separate a constant offset from an error that accumulates over consecutive parts.	Observe the same datum for several cycles and identify which motion changes first.
Wrinkle begins near one film edge	Roller-axis alignment, unequal edge tension or an angled entry path	Trace both film edges before, through and after the contact zone.	Correct geometry before changing heat; the wrinkle origin should disappear during dry motion.

Release criteria

What a stable result looks like

The upper, centre and lower portions of the decoration meet the agreed seam and position standard.
The container remains round and undamaged, with no unacceptable rim, handle or rib interference.
Film tracking, peel and rewinding remain stable through consecutive cycles.
The approved result repeats after normal reloading, not only on one carefully positioned sample.
