ExDrive is a track spectrodensitometer launched by CHNSpec, designed specifically for color measurement and quality control requirements in the printing industry.
Adopting automatic track scanning technology, the instrument can continuously measure multiple color patches along the printing control strip, quickly acquiring ink density, spectrum and color data of each ink zone. It provides reliable measurement basis for printing quality judgment and ink adjustment.
Combined with compatible printing quality management software, it further enables color deviation analysis, printing quality evaluation and ink zone adjustment guidance. It helps printing enterprises improve production efficiency, optimize color consistency and reduce printing material waste.
Automatic track scanning at a speed of up to 100 mm/s. It continuously measures multiple color patches on control strips and eliminates manual spot-by-spot testing.
Supports spectrum data, Lab color values, ink density and other parameters. It provides data support for color difference analysis, dot gain (TVI), gray balance and other evaluations.
Compatible with M0, M1, M2 measurement modes, adapting to different printing materials and application scenarios.
Scan control strips to obtain color and density data of each ink zone. The software identifies deviations to offer references for press operators to adjust ink, reducing repeated test printing.
Comes with third-party printing quality management software for data analysis, standard comparison, quality judgment and report generation.
Quickly detect color deviations, shorten make-ready time, reduce paper waste and ink consumption, and improve color consistency and quality stability.
