At FESPA 2025, Digital Sign Technologies introduced a groundbreaking method for assessing nozzle performance on inkjet printheads during the cleaning process – directly on the Print Head Doctor (PHD) machine. This new technique, known as drop watching , offers a faster and more accurate alternative to traditional test prints and the widely used “curtain” method. A Smarter Way to Test Nozzles Traditionally, checking nozzle function involved printing a pattern or observing a f

Jetting Print Heads During Cleaning Helps Increase Recovery Rate The unified system* comprising the Print Head Doctor (PHD) and the Print Head Tester (PHT) now intelligently actuates piezo crystals inside a print head during cleaning cycles. This innovative approach reduces overall cleaning time and increases the percentage of successful cleaning outcomes (also known as the recovery rate). Piezo actuation, precisely controlled by the unified system, is now embedded into the c
