Print Quality

Inkjet print quality. Historically, accurate prediction of inkjet printer or printhead performance has been impossible until the printed output was produced. But reliable data is needed much earlier in the process. For this reason, major inkjet head manufacturers rely on QEA’s IAS products to measure jetting straightness, drop position, drop size, satellite dots, missing dots and many other critical quality measures. Our systems measure print quality not only on paper, but also on many other substrates including textiles, glass, and ceramics. Our IAS systems evaluate overall printer performance with measures such as banding, jitter and coalescence. For fast, reliable performance monitoring, whether for R&D, production QC or competitive benchmarking, our IAS products are the tools you need.
