The Rainbow TamperGuard® Custom Print Tamper Evident Security Label combines TamperGuard's non-residue void-pattern tamper evidence with your choice of custom-printed content — logos, sequential serial numbers, barcodes, QR codes, or any branded design that transforms the tamper seal into a product authentication and inventory management tool. Available in a 250-label starter/evaluation pack, this Rainbow compact rectangle (1" x 0.5" / 25mm x 13mm) format is designed for testing performance, piloting a security program, or deploying targeted tamper evidence on specific high-value items.

The holographic rainbow finish produces a dynamic color-shifting iridescent effect that varies under different viewing angles — simultaneously serving as a premium visual authentication feature and a tamper-evident seal. The rainbow holographic effect is virtually impossible to replicate with standard printing, making these labels both visually striking and inherently anti-counterfeit. The 1" x 0.5" (25mm x 13mm) compact rectangle is one of the most broadly applicable TamperGuard® sizes — wide enough for clear visibility and meaningful tamper evidence, yet compact enough for most standard packaging closures, product boxes, and device interfaces.

TamperGuard®'s defining advantage over standard tamper-evident labels is its non-residue adhesive system: when the label is removed or tampered with, the void pattern activates visibly on the label itself without leaving adhesive residue or ghost marks on the underlying surface. This makes TamperGuard® ideal for sensitive substrates, reusable equipment, high-gloss packaging, and any application where surface integrity must be maintained after a label is assessed or removed.

Custom print options include sequential numbering for item-level asset tracking, integrated barcodes compatible with major inventory management platforms, QR codes for mobile authentication workflows, and full-color logos for branded security programs that reinforce product identity at every consumer touchpoint.
