Applying it

Print it, sign it, weave it in

The crystals ride in ordinary ink, thread, film and plastic, so they go on with tools people already use. The newest is the simplest: a handheld printer that puts an invisible code on a card back, a shirt tag or a seal in one pass.

A code in one pass

The crystal ink fits a standard HP45-format thermal cartridge, the kind many handheld coders already use. Pick a surface, print, then change the light.

A trading card back. The code lands in the blank panel, invisible in daylight.

Where a handheld goes

No press, no factory change. The printer goes wherever the piece already is, and every code it prints is logged to the Forever library.

Equipment rooms

Code the inside tag of every jersey as it is issued, and again when it comes back from the game.

Signing tables

Mark the ball, photo or card next to the pen signature, so the piece and the autograph share one record.

Card shops and graders

Code card backs and slabs on intake. The code links the card to its grade and its history.

Fulfillment

Seal hobby boxes, packs and shipping cartons, so a searched or resealed box shows up.

Every way it goes on

Pick the method by where the piece is made. Most programs use two or three together: one in the material, one printed, one in the signature.

Handheld inkjet

Invisible codes, serial numbers and logos printed by hand in one pass. Standard HP45-format cartridge.

Best for card backs, shirt tags, jock tags, balls, seals and boxes

Inkjet on the line

The same ink on a production line: a thermal cartridge, or continuous UV-cured printing that never touches the product. Proven at 800 units a minute on vials.

Best for card print runs, hang tags, tickets and passes

The pen

Two crystal inks and reflective flakes in one tip. The proof is made in the signature itself.

Best for autographs on anything See the pen

Thread and yarn

Fibers spun with crystals, sewn into seams and woven into labels.

Best for jersey seams, jock tags, patches and relic swatches

Heat-transfer film and screen ink

Crystals in the adhesive film behind tackle twill, in heat-press vinyl or in screen-printing ink.

Best for numbers, nameplates and printed fan shirts

Coatings, varnish and foil

A blend in the clear coat, the press varnish or the foil adhesive.

Best for card stock, parallels, guitar finishes and posters

Plastic, compounded

Crystals mixed into the resin before it is molded. The part looks and feels the same.

Best for guitar picks, card slabs and top-loaders

Labels and seals

Crystals in the label stock, the varnish or the seal adhesive, so a peeled seal cannot be reused.

Best for packs, cases, certificates and auction lots

At line speed

For card makers and apparel licensees, the crystal ink runs on the line with everything else. A continuous UV-cured printer puts the code down without touching the product, and a cure lamp sets it before the next item arrives.

  • Invisible in daylight. Nothing changes in the design or the finish.
  • Glows under UV. Anyone with a UV light can see the code.
  • A covert layer. Only the Spark Labs reader can confirm the crystals inside it.
Crystal ink printed at line speed, from the Intelligent Material inkjet program.
