Printing Densitometer EX Series EX SE/PRO/MAX
The CHNSpec EX series of handheld printing densitometers are designed specifically for the printing
industry. They can accurately measure the color density of various printing processes such as offset
printing and gravure printing, quickly obtaindata, and help practitioners effectively control color quality
and correct deviations in a timely manner. Its handheld design is lightweight and easy to carry, and can
provide reliable color management support anytime and anywhere to ensure the consistency of printed
colors.
