This geometry perfectly replicates how the human eye perceives color on flat surfaces, effectively eliminating interference caused by the gloss of the ink layer.<\/li>\n<li><strong>Ultra-Precise Repeatability (Error margin less than or equal to 0.03):<\/strong> A valuable upgrade of the EX Pro version lies in its extreme stability, with a repeatability index of \u0394E*ab less than or equal to 0.03 when measured on a standard white tile. This specification guarantees that the device always delivers absolutely consistent results, even through repeated consecutive measurements.<\/li>\n<li><strong>Comprehensive Color Densitometry System:<\/strong> The EX Pro provides the full range of analytical functions of a dedicated densitometer for printers, including: measuring the color density of CMYK process inks, tone value increase (Dot Gain), dot area percentage verification, print contrast, and ink trapping.<\/li>\n<li><strong>Full Support for Measurement Conditions (M0, M1, M2, M3):<\/strong> The device fully complies with the ISO 13655 standard using smart filters. In particular, the M1 mode enables precise color measurement on modern printing papers containing Optical Brightening Agents (OBA), while the M3 mode (polarization filter) allows stable color control even when the ink layer is still wet right out of the printing press.<\/li>\n<li><strong>High-Definition Camera Positioning:<\/strong> An integrated real-time viewing camera allows operators to easily align the measurement aperture with small color patches on control strips (Color Bars) or micro-text and logo details without worrying about clipping the edges.<\/li>\n<\/ul>\n<p><a href=\"https:\/\/maydomau.vn\/wp-content\/uploads\/2026\/07\/Handheld-Printing-Densitometer-Accurate-Color-Spectrum-Analyzer-for-Offset-Gravure-Printing-Densitometer-EX-SE-EX-PRO-EX-MAX-2.jpg\"><img decoding=\"async\" class=\"wp-image-3460 size-full aligncenter\" src=\"https:\/\/maydomau.vn\/wp-content\/uploads\/2026\/07\/Handheld-Printing-Densitometer-Accurate-Color-Spectrum-Analyzer-for-Offset-Gravure-Printing-Densitometer-EX-SE-EX-PRO-EX-MAX-2.jpg\" alt=\"\" width=\"800\" height=\"514\" title=\"\" srcset=\"https:\/\/maydomau.vn\/wp-content\/uploads\/2026\/07\/Handheld-Printing-Densitometer-Accurate-Color-Spectrum-Analyzer-for-Offset-Gravure-Printing-Densitometer-EX-SE-EX-PRO-EX-MAX-2.jpg 800w, https:\/\/maydomau.vn\/wp-content\/uploads\/2026\/07\/Handheld-Printing-Densitometer-Accurate-Color-Spectrum-Analyzer-for-Offset-Gravure-Printing-Densitometer-EX-SE-EX-PRO-EX-MAX-2-300x193.jpg 300w, https:\/\/maydomau.vn\/wp-content\/uploads\/2026\/07\/Handheld-Printing-Densitometer-Accurate-Color-Spectrum-Analyzer-for-Offset-Gravure-Printing-Densitometer-EX-SE-EX-PRO-EX-MAX-2-768x493.jpg 768w, https:\/\/maydomau.vn\/wp-content\/uploads\/2026\/07\/Handheld-Printing-Densitometer-Accurate-Color-Spectrum-Analyzer-for-Offset-Gravure-Printing-Densitometer-EX-SE-EX-PRO-EX-MAX-2-510x328.jpg 510w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/a><\/p>\n<h2><strong>Technical Specifications:<\/strong><\/h2>\n<p>Measurement\/illumination aperture: \u03a62mm\/5mm\uff0c\u03a61.5mm\/3mm<\/p>\n<p>Battery capacity: One single charge can continuously measure 8,000 times, 7.2V\/3000mAh<\/p>\n<p>Density range: 0.0 D\u20133.0 D<\/p>\n<p>Density standards: Status A, E, I, T, M<\/p>\n<p>Standards compliance: ISO 5-4:2009(E), ISO 13655:2017, CIE No. 15<\/p>\n<p>Device display: 3.5-inch full-color screen<\/p>\n<p>Supported languages: Simplified Chinese, English<\/p>\n<p>Light source: Balanced full-band LED light source + UV<\/p>\n<p>Measurement modes: M0, M1, M2, M3<\/p>\n<p>Measurement geometry*: 45\/0<\/p>\n<p>Measurement time: Approx. 1.5 seconds<\/p>\n<p>Measurement repeatability: Density value: \u22640.001D, chromaticity value: dE*ab\u22640.03<\/p>\n<p>Wavelength interval: 10nm<\/p>\n<p>Wavelength range: 400-700nm<\/p>\n<p>Light source lifespan: 1 million measurements over 10 years<\/p>\n<p>Data storage: 100 master standards, 10,000 test samples;
