| Container control | Flat, oval, tapered, lightweight or handled packs may need different guide, side-belt, spacing or top hold-down arrangements. More demanding control can add engineering, tooling and trial work. |
| Applicator heads | Front and back labels can have different widths, lengths, roll sizes and positions. Each head must have enough adjustment and capacity for the confirmed format range. |
| Label sensing | Paper, opaque film and clear label constructions can need different sensing methods. The quotation should state the label material and the sample basis used to select the sensor. |
| Coding and inspection | Batch coding, barcode checking, label-presence inspection and reject confirmation add interfaces, mounting, controls and acceptance tests beyond basic label application. |
| Conveyors and controls | Infeed spacing, conveyor height, direction, line speed, upstream and downstream signals, accumulation and emergency-stop integration affect the final line scope. |
| Changeovers | A broad pack range may require format parts, adjustable guides, recipes, setting records or tooling. The quotation should separate included formats from future additions. |
| Trials and acceptance | Representative samples, sustained runs, placement measurements, starts and stops, fault recovery and documentation determine how suitability is demonstrated. |
| Installation and support | Delivery access, positioning, utilities, commissioning, operator handover, spare parts and service support should be compared alongside the machine supply. |
