Imprint Lite

Imprint Lite - Free Anti-Dupe

Every valuable item gets an invisible serial number. When the same number turns up in two places, the copy is removed.

Paper, Purpur, Spigot, Folia. Minecraft 1.16.5 to 26.x. Java 17+. No other plugin needed.

What it does

A duplication exploit makes a second copy of an item. Imprint does not look for the trick, it

looks for the result:
two items with one serial number.

• Tools, weapons, armour, elytra, shulker boxes and enchanted books get a serial number in their own data. Players cannot see it.
• Imprint remembers where each serial was last seen (inventory, ender chest, container, ground, item frame, a donkey's chest).
• A serial that shows up somewhere new is checked in both places, twice, a little apart. An item that simply moved is cleared on the spot. Only a serial that is still in both places the second time is a duplicate, and the copy found second is removed.
• In doubt, nothing happens: a chest in an unloaded chunk, a player who just left, an item that moved between the two looks.
• Kits and shop entries that hand out copies of a stored item are recognised as templates and left alone.
• Storage windows are closed before a player goes through a portal or teleports far, and a donkey's or minecart's window when it travels or is destroyed.
• duplicates.action: alert only reports: a good way to start.
• Creative players and imprint.exempt are never marked or checked.

Installation

• Drop Imprint-Lite-1.0.0.jar into plugins/ and restart.
• It works with the defaults.

It marks items that do not stack, so a dupe of 64 cobblestone is not found. It does not look

inside shulker boxes or bundles.
