Capsular Ink

Functional printing solution with microencapsulated inks, applicable to multiple substrates and activated by external stimuli.

Capsular Ink is a line of microencapsulated inks developed by IPS for functional printing applications. Unlike traditional inks, whose purpose is exclusively visual, inks with microcapsules incorporate particles containing active substances — fragrances, photochromic pigments, thermochromic pigments, liquid crystals — protected within a polymeric shell.

During the printing process, the microcapsules are deposited onto the substrate together with the ink vehicle. The functional effect is activated only when a specific external stimulus intervenes: heat, UV light, pressure or friction. In response to this stimulus, the microcapsule can break — releasing its contents — or modify its optical properties without breaking, creating dynamic and reversible visual effects.

This mechanism transforms print into an interactive and sensory interface, opening up application possibilities that go far beyond traditional visual communication.

Difference from traditional inks

Unlike traditional inks, Capsular Ink is able to react to external stimuli, adding a functional and interactive dimension to print. The following table illustrates the main differences between the two technologies:
Traditional inks Inks with microcapsules
(Capsular Ink)
Function Visual only Visual + sensory / interactive
User interaction Passive Reactive (light, temperature, contact)
Marketing value Standard High experiential impact

FAQ — Capsular Ink

Frequently asked questions about microencapsulated inks for functional printing

Capsular Ink is a line of inks that incorporate microcapsules containing active substances (fragrances, photochromic pigments, thermochromic pigments, liquid crystals). Unlike a traditional ink, whose purpose is exclusively visual, Capsular Ink also performs an additional function that is activated in response to an external stimulus — heat, UV light, friction or pressure. The result is an interactive and sensory print.

Depending on the chosen variant, Capsular Ink can respond to:

Capsular Ink is compatible with screen printing and flexography.
Screen printing is the preferred technique as it allows thicker layers to be deposited, reduces mechanical stress on the microcapsules and ensures optimal functional performance.
Flexography is compatible for high-volume production, but requires careful control of pressure and speed to preserve the integrity of the capsules.

Capsular Ink can be applied to:

  • Paper and cardboard (including coated)
  • Plastic materials (PET, PP, PE)
  • Self-adhesive labels
  • Textile materials

Other substrates can be evaluated upon request → Contacts

Capsular Ink is aimed primarily at printers who can offer it to their clients in sectors such as:

The Capsular Ink line includes three families:

No, provided that the compatible printing techniques (screen printing or flexography) are used with the correct parameters. The microcapsules are designed to withstand the mechanical and thermal stress of the printing and drying process, preserving the active ingredient until the moment of activation by the end user.

Yes, Capsular Ink can be used in combination with traditional inks in the same print job. This possibility allows combined visual and functional effects to be created — for example, a traditional graphic enhanced with a scented area or a zone that changes colour with heat or UV light.

Yes, within the available options for each Capsular Ink variant it is possible to choose or customise the fragrance, pigment colour or activation temperature. For specific requirements not covered by the standard offering, IPS provides a dedicated development and prototyping service → Learn more

Yes, microencapsulated thermosensitive or photosensitive inks can be used in security printing applications. The immediate and verifiable visual response with a UV source or exposure to reaction temperature is difficult to replicate without access to the original technology, making them suitable for authenticity labels and guarantee seals.
