The PDC-SII Print Density Control-Spectrophotometer scans and measures the color bar on printed sheets, converting the results to numeric data for display and providing feedback to the press-side as necessary. Compared to the conventional PDC-S, several functions have been enhanced and ease of use during printing is significantly improved through faster measurement and display.

Color adjustments that once depended on the operator’s visual check are controlled by numeric data obtained by measuring and analyzing color evaluation indices such as solid densities, dot gain, trapping, contrast, L*a*b, ?E, hue error, and grayness. This approach vastly increases color consistency and operating efficiency.

PDC-SII incorporates a feedback control function that automatically calculates the appropriate ink key openings when color variation occurs, feeding this data to the press so that densities approach target values. The handheld scanning instrument enables spot assessments anywhere in the image, data registration of special inks, and color management based on spectral reflectance.

High-level color management, reduced operator workload, and higher operating efficiency. PDC-SII: The essential system for printing standardization.
