The first run of hang tags delighted the customer. Three months later comes the repeat, and the feedback is that the colour is off and the board feels soft. The factory checks everything: same plate, same 350 gsm board. The problem is that nobody recorded the conditions of the first run. Repeat-order drift in trims is rarely a technical problem; it is a missing file.
This guide covers five things: the four sources of repeat-order drift, the five records every trim item needs, why the same grammage does not give the same hand, how to write a colour tolerance, and when plates and dies must be remade.
1. Four Sources of Repeat-Order Drift
A second run has more variables than it seems: board from a different mill batch differs in whiteness and bulk; ink from another brand or lot shifts a spot colour by half a shade; foil temperature and pressure depend on the operator, changing brightness and adhesion; a different subcontractor means different die radii. Each difference sits inside tolerance on its own. Stacked together, they read as a different product.
- Board: same grammage, different pulp and coating weight, visibly different hand and whiteness; recycled pulp is the least stable
- Ink: lot-to-lot variation in spot colours and different dot gain in four-colour work; large solids show the shift first
- Finishing: foil temperature, pressure and dwell, emboss depth, lamination type (gloss and matt cannot be mixed)
- Equipment and outsourcing: worn dies, a different press, a changed subcontractor — all alter finished size and edge feel
2. The Repeat-Order File: Five Records You Must Keep
Whether a repeat matches depends on what the first run left behind. Keep one file per trim item, electronic plus physical, with five things that cannot be missing: the customer-approved sample, the board swatch and grammage record, the colour card and measured colour difference, plate and die numbers, and the process parameter sheet. Number the file so it maps to the customer PO and your internal item code — otherwise nobody finds it six months later.
| Record | What it contains | Form |
|---|---|---|
| Signed sample | The signed first article, dated, with the manual version noted | Physical plus scan |
| Board swatch | Mill, grammage, pulp type, coating, whiteness | A4 physical swatch plus parameters |
| Colour card | Spot formula, Pantone number, measured ΔE | Physical card plus data sheet |
| Plates and dies | Plate number, die number, die-line drawing | Number register plus electronic drawing |
| Process parameters | Foil temperature and pressure, lamination, emboss depth | Sheet travels with the order |
3. Board and Film: Same Grammage Is Not the Same Hand
350 gsm is a weight, not a specification. Two 350 gsm boards can differ by several points of whiteness between virgin and recycled pulp, by a couple of grams of coating, and the hand goes from crisp to soft; different bulk means a five percent difference in caliper at the same weight, and a stack of tags looks different in the bag. Write only 350 gsm white board on a repeat and the supplier ships from stock — the difference is guaranteed.
- Be specific: grammage plus pulp type or brand, whiteness, coating, and whether the same mill batch is required
- Films too: OPP and PET differ in stiffness, and matt versus gloss differ in friction, which shows up on automatic packing lines
- On small repeats you can ask for the same batch; on large ones, book the mill slot in advance — especially in peak season
4. Colour: Write the Tolerance as a Number
Do not verify a repeat by saying it looks like last time. Colour difference only means something as ΔE: large solids on hang tags usually accept ΔE up to 2, woven labels relax to 3 because of yarn and weaving limits, and foil and spot colours need an agreed figure because materials move them further. Measure the same point under the same illuminant with a spectrophotometer, or at least compare with a grey scale in a viewing booth, and record the reading — not just the word pass.
- Fix the illuminant and viewing geometry: judge under D65, never under office fluorescents or by a window
- Record the measured ΔE and the grey-scale rating, not a pass or fail
- When the customer has a brand colour card, that card is the reference — not a screen or an inkjet proof
5. Old Plates and Dies: When They Must Be Remade
Plates and dies have a life. Offset plates start deforming dots after a certain number of impressions, die rules round off with use, foil stamps oxidise at temperature. A small repeat can reuse them, but check the first article for burrs on the die line and for filled-in dots; a large repeat or more than a year since the last run justifies remaking. Settle the cost and ownership of remakes when the first order is placed, not when the repeat arrives.
