Digital Sign unveils new innovations at Loupe Americas

Digital Sign Technologies, a manufacturing and digital printing expert, will showcase its latest innovations at Loupe Americas 2026. 

This year’s exhibit will feature Print Head Doctor (PHD), AI-enabled models PHD17 and PHD18, its flagship systems for maintaining and recovering printheads.  

Print Head Tester (PHT), a newly launched device that assesses printhead performance after cleaning, storage, or as new. It instantly evaluates nozzle health to ensure consistent print quality. 

The Ink Tester is a compact, AI-powered device that delivers fast, precise ink evaluation with specific printheads. Designed for manufacturers, R&D labs, and demanding users, it eliminates guesswork, reduces inefficiencies, and ensures confidence in results. 

New Modular Multi-Head Print Head Tester (PHT-M) will be launched at Loupe Americas 2026. The company’s new Modular Multi-Head Print Head Tester (PHT-M) allows users to test multiple printheads using the same modular device. It is best suited for companies using more than one printhead type, is easy to use, and allows users to quickly validate different printhead types with one device by changing the printhead modules. 

This end-to-end printhead lifecycle system, Print Head Doctor (PHD), Print Head Tester (PHT), and Ink Tester, forms the industry’s most comprehensive workflow for recovering, validating, and protecting inkjet printheads. 

Print Head Doctor 17 (PHD17) and Print Head Doctor 18 (PHD18) are AI-enabled models and their advanced technology and efficiency maintain and recover print heads. The PHD17 and PHD18 are designed to extend the life to print heads, significantly reducing costs for businesses by avoiding the need for frequent replacements. 

The PHD17 is suitable for regular print head maintenance, unclogging severely blocked heads, and supporting all types of inkjet print heads, including UV, solvent, aqueous and specialty ones. It automatically generates reports with photos of print head nozzle tests taken 'before' and 'after,' allowing for full visibility of the print head recovery process. It is easy to use, fully automated, and remotely controlled. 

The PHD17 is perfect for businesses with moderate maintenance needs, as it can clean one or two print heads at a time. 

For businesses with higher demands, the PHD18 offers a multi-head recovery system. It retains all the features of the PHD17 but extends its capacity to clean up to ten print heads simultaneously.  

The Print Head Tester (PHT) is a compact, easy-to-use device designed to quickly and accurately assess the condition of inkjet printheads. It allows users to validate printheads after cleaning, storage, or new, helping ensure optimal print quality while reducing costly downtime. 

The testing process takes just three minutes and provides a clear visual of nozzle performance, eliminating guesswork from printhead evaluation. The PHT uses standard photo paper and your preferred ink, making printhead testing flexible and cost-effective. 

Ideal for manufacturers, print shops, dealers, ink producers, service technicians, and refurbishers, the Print Head Tester helps determine whether a printhead is ready for use or requires further cleaning.  

It also works in tandem with the Print Head Doctor to provide a complete technology for printhead recovery and maintenance.  

The Ink Tester is a compact, AI-powered device that delivers fast, precise ink evaluation with specific printheads. Designed for manufacturers, R&D labs, and demanding users, it eliminates guesswork, reduces inefficiencies and ensures confidence in results.
