Machines and consumables for pre-inked stamps

All our machines and consumables for the manufacturing of pre-inked stamps

Advantages of the pre-inked stamp

The pre-inked stamp is an all-in-one, ready-to-use marking tool that integrates ink directly into its structure.

Mounted on a special frame, it allows for pressure adjustment, thereby modulating the intensity of the imprint.

It is less common on the market due to technical manufacturing constraints. However, thanks to the patented flash frame process developed by our company, its production is now simplified: no more tedious cleaning or expensive equipment required.

It stands out due to an innovative design combining ink gel and a felt reservoir, ensuring a crisp, high-quality impression.

This process paves the way for a unique offering in a market that remains largely untapped.

Pre-inked stamps

Pre-inked stamps represent one of the most technically demanding marking processes, requiring great precision at every stage of curing and production.

To make this easier, Thermoflan has developed the “framed matrix board” — an innovative solution that streamlines production while delivering exceptional quality and consistency.

Paired with our high-precision manufacturing equipment, designed and assembled in-house, it enables you to create sharp, long-lasting, and exclusive stamps.

How does the manufacturing of pre-inked stamps work?

Steps for producing a pre-inked stamp:

Creation of the negative film

  • Printing the visual in black on a transparent medium, serving as a mask for exposure.

Photopolymer exposure

  • The photopolymer is exposed to UV light through the film, which hardens the transparent areas and leaves the black areas intact.

Plate development

  • The non-hardened parts are removed by washing, revealing the relief of the imprint.

Complete drying

  • Evaporation of residual moisture to stabilize the plate.

Final hardening – Post-polymerization

  • A new UV exposure to strengthen the resistance and longevity of the photopolymer.

Matrix molding

  • The engraved plate is used as a mold to create a recessed matrix in a flexible material, the flan cadre, in the molding press.

Gelation

  • After removing the flan cadre from the mold, an ink gel is applied into the flan cadre. Covered with a felt pad, it is baked in the molding press.

Cold demolding

  • The felt and gel assembly is removed from the flan cadre. It forms a spongy mass of ink.

Mounting on an adjustable holder

  • The pre-inked gel is cut and attached to a special holder that allows the user to adjust the pressure, influencing the amount of ink released.

Advantages and uses of the pre-inked stamp

ADVANTAGES

Exceptional marking quality: the marking is precise, sharp, and clean, even for very fine details. No smudging or excess ink.

All-in-one technology: the stamp integrates the ink directly into its structure (ink gel + felt reservoir).

Clean and practical use: No direct contact with ink and no risk of staining hands or documents.

No daily maintenance required.

High capacity: can perform up to 50,000 impressions before needing a refill. Easy re-inking possible via a hatch without disassembly.

Advanced customization: various formats (round, rectangular, square…). Insertion of logos, QR codes, custom fonts. Choice of several ink colors (black, blue, red, green…).

Innovative manufacturing process: with the patented flan frame process, production is simplified, fast, and clean.

Market differentiation: high-end, still uncommon. Allows manufacturers or resellers to offer an innovative and original solution.

USES

Businesses and administrations: signing documents, marking dates, addresses, SIRET numbers, legal mentions, etc.

Liberal professions (doctors, lawyers, architects…): for professional information, official seals, validation stamps.

Logistics and industrial sectors: package tracking, numbering, quality control, inventory management.

Accounting and finance: for terms such as “Paid”, “Validated”, “Copy”, “To be archived”, etc.
