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, unsuitable 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 are checked together.
Before die production, print allowances and critical tolerance zones are discussed.
- Print and cut references are matched.
- Sheet size consistency is checked.
- Critical visual areas are 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 are 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.
Quote details we clarify together
When the file, material, quantity and deadline are clear, the quote conversation moves faster and with less back-and-forth.
- Current revision file
- Material and quantity details
- Critical dimensions or production notes
- Deadline expectation and delivery preference
