A good die does not only cut the first piece. It keeps the same result during production, which makes the checklist as important as the die.

Rough or burred edges

Rough edges can come from rule wear, wrong rule choice, material hardness or insufficient pressure. Rule type and pressure balance become especially important with thick or fibrous substrates.

To diagnose the issue, compare different positions on the same sheet. A local issue may point to mounting or pressure distribution; a general issue may point to rule or material compatibility.

  • Check rule tip and pressure.
  • Separate local issues from general issues.
  • Review setup when material changes.

Cut shift and print register problems

If the cut shape shifts against the print, the die is not always the only cause. Print layout, sheet consistency, machine setup and register marks should be checked together.

Before die production, print allowances and critical tolerance zones should be discussed.

  • Print and cut references should match.
  • Sheet size consistency should be checked.
  • Critical visual areas should be marked early.

Difficult label peeling or liner cutting

If labels are hard to peel, cut depth may be insufficient. If the liner is cut, pressure or rule height may be too aggressive. In both cases, peel tests should be done from multiple positions.

A new material batch may not behave the same as the previous one.

  • Test corners, centers and fine details.
  • Hold the liner to light.
  • Note material batch changes.

Carton cracking or poor waste release

Crease cracking can come from board thickness, grain direction, ink coverage or channel choice. Poor waste release can come from stripping, rubbering or detail geometry.

During approval, check several pieces from different positions, not just one sample.

  • Inspect crease lines on the folded product.
  • Consider waste release at machine speed.
  • Check multiple samples.

Short pre-quote check

If these items are clear, quote and production discussion on WhatsApp moves faster.

  • Was the issue photographed?
  • Is it local or general?
  • Did material or print change?
  • Were samples checked from multiple positions?
