Knowledge base
Choose support, datum, contact method, film path and station handoff from the real decoration surface instead of relying on a product name alone.
Two products with similar names may need different fixtures and contact paths, while products from different industries may share the same geometric problem. Selection begins by describing the actual print band, part stiffness, accessible support and required decoration coverage.

Overall product dimensions do not define the working surface. Record where the artwork begins and ends, which edges or openings limit access, how the part is supported and whether the decorated surface changes shape under load.
A nominally flat part still needs stable backing, repeatable location and a contact tool aligned to the supported surface. Large, thin or irregular panels can bend locally, so contact evidence is more useful than the product label alone.
A cylindrical print band has the same circumference along its height; a tapered band does not. For tapered work, the useful diameters are measured at the upper and lower boundaries of the actual decoration band, together with the axial distance between them.
Irregular and contour parts should be described by changing curvature, accessible support, local stiffness and the route the contact tool must follow. A product category cannot prove that one contour fixture or motion path will fit another shape.
Long tubes and twin cartridges are not located by one point alone. End position, long-axis direction, rotational facing, cross-section orientation and the target print face may all need to survive feeding, gripping and cross-station transfer.
A thin cup or container may arrive in the correct area but still lack a stable contact surface. An internal mandrel or equivalent support should establish shape, axis, insertion depth and load path before the part enters the process zone.
Questions
No. The print-band geometry, support, stiffness, decoration coverage, seam requirement and loading method determine the mechanism. Products with the same name can differ in all of these conditions.
Use the diameters at the actual upper and lower boundaries of the decoration band. A rim or maximum outside diameter is relevant only when it coincides with that working boundary.
Arrival confirms an area or handoff. The final datum may also require seating depth, axial stop, rotational facing, internal support and stable contact. Verify the whole geometry chain at the process station.
