April 15, 2026
Mississauga, Ontario, Canada – Digital Sign Technologies Inc., a global leader in printhead recovery and testing solutions, is pleased to announce the launch of its new Modular Multi-Head Print Head Tester & Ink Tester (PHT-M).

Designed for companies that use multiple printhead models, the PHT-M combines advanced printhead testing and ink validation in one compact, modular platform. By simply changing the printhead module, users can quickly test a wide range of printhead types without the need for multiple dedicated testing devices—saving time, reducing equipment costs, and simplifying workflow.
​
The PHT-M quickly and accurately evaluates the condition of inkjet printheads after cleaning, storage, or when new. In just three minutes, it provides a clear visual assessment of nozzle performance, eliminating guesswork and helping ensure consistent print quality while reducing costly production downtime.
​
Using standard photo paper and the customer's preferred ink, the PHT-M offers a flexible and cost-effective solution for validating printhead performance across multiple printer platforms.
In addition to printhead testing, the integrated Ink Tester enables users to evaluate printing inks in minutes before they are introduced into production. This helps identify suboptimal or incompatible inks that could negatively affect print quality or damage printheads, reducing costly downtime while protecting valuable printing equipment.
​
Ideal for manufacturers, print shops, print service providers, printhead dealers, ink manufacturers, service technicians, and printhead refurbishers, the PHT-M enables users to verify both printhead performance and ink quality before production begins, ensuring optimal print quality and greater process reliability.
​
When paired with the Print Head Doctor (PHD), the PHT-M forms a complete printhead lifecycle solution—allowing users to recover, validate, and certify printheads before they ever return to production. Together, these technologies maximize print quality, minimize downtime, extend printhead life, and reduce operating costs.
