Product Overview

The KR‑512 color‑assessment light booth is multi‑source standard‑lighting cabinet for visual colour‑evaluation work. It integrates six internationally‑recognised light‑source groups: D65, TL84, UV, F, CWF and U30. Users can switch among individual light sources to inspect metamerism, colour‑shade deviation and colour‑fastness of test samples. It delivers stable, flicker‑free illumination environment regardless of workshop ambient lighting, cloudy weather or dim indoor surroundings.

Compliant with JIS‑Z8724 and CIE‑30 requirements, this unit is widely adopted across textile‑dyeing, leather, plastic‑parts, paint‑ink, printing‑packaging, ceramic and cosmetic sectors. It supports incoming‑material colour‑check, batch‑production QC, colour‑proof confirmation and finished‑goods acceptance procedures.

Core Product Competitive Advantages

1. Six‑complete‑set international‑standard light‑source configuration Covers mainstream lighting conditions for global colour‑verification: D65 simulates northern‑sky daylight; TL84 matches European‑Japanese retail‑store lighting; CWF / U30 reproduce US commercial‑scene illumination; F simulates domestic warm‑yellow ambient light; UV source detects fluorescent‑whitening‑agent migration. Multiple‑light‑source combination effectively identifies metameric colour‑mismatch risk for export‑oriented goods.
2. Integrated flicker‑free drive circuit, low‑heat‑emission design Adopts integrated electronic control module. Lamps produce minimal heat output during long‑time running; no visible light‑flicker which avoids visual‑judgement drift caused by stroboscopic effect. Each light‑source channel can be individually switched on / off for flexible testing workflow.
3. Neutral‑grey inner‑chamber & light‑shielding cabinet structure Inner cavity uses neutral‑grey anti‑reflective coating, eliminating stray‑light reflection interference. Enclosed light‑tight housing prevents outside ambient‑light from disturbing visual‑comparison results, securing repeatable colour‑judgement outcomes.
4. Compact folding‑type cabinet layout, easy‑maintenance setup Fold‑back housing structure saves storage footprint. Lamp replacement and diffuser‑panel maintenance can be finished without complicated disassembly. Overall cabinet appearance is neat, well‑suited for lab‑bench or production‑quality‑control‑station deployment.
5. Global‑voltage‑adaptable power‑input Supports 110 V / 220 V dual‑voltage input to fit factory power‑grid conditions in different regions. Optional accessories include replacement lamps, light diffuser sheets and 45‑degree observation bracket to satisfy diverse test‑operation needs.

Standard Complete Test Operating Workflow

1. Pre‑Test Preparation Position light booth on stable horizontal work‑bench, keep surrounding area away from strong coloured‑reflective objects. Connect power‑supply. Confirm all lamp‑channels respond normally when switched. Prepare reference‑standard sample and production‑test‑sample.
2. Sample Placement Open booth cover, lay reference‑sample and test‑specimen side‑by‑side onto inner neutral‑grey base‑plane. Keep samples flat without curling. For formal evaluation, use optional 45‑degree viewing‑stand to maintain standard observer viewing‑angle.
3. Light‑Source Switch‑Over & Visual Comparison Turn‑on target light‑source channel one‑by‑one. Carry‑out colour‑shade, hue and metamerism comparison under each lighting condition. For UV channel: check fluorescence effect brought by optical‑brightener inside materials. Record colour‑difference performance under every light‑source condition.
4. Result Judgement & Documentation Compare test‑sample against master‑reference. Document colour‑deviation level, metamerism risk and fluorescence‑phenomenon. Generate QC‑inspection record for incoming‑check or batch‑release‑files.
5. Post‑Test Tidying Switch‑off all lamp channels before cutting main power. Close booth cover to prevent dust contamination on diffuser‑panels and lamp‑tubes. Periodically check lamp‑ageing condition; replace ageing lamps to guarantee illumination‑quality for accurate colour‑assessment.
