Known as the Area Color Inspection System (ACIS), the technology allows users to perform fast, automated measurement of text and symbol shape (inclusions and exclusions), dimensions, color, and contrast.
According to Radiant, many products sold today are required to display markings such as text, logos, symbols, and numbers for identification, traceability, regulatory compliance, user information, and branding.
Typically, the lettering is applied to the surface of product components during the manufacturing and assembly process using laser etching, printing, or similar methods. Product makers must ensure that these markings are legible, correctly formed, and meet color specifications.
“Manufacturers typically use multiple methods to inspect markings,” said Hubert Kostal, vice-president of business development and the leader of Radiant’s Advanced Vision business. “Device makers may use machine vision cameras for text inspection and area measurement. Plus, some combination of spectrometers and human inspectors for color measurements. This creates a lot of inefficiency.”
According to Radiant, ACIS simplifies the process by allowing manufacturers to meet both inspection needs in a single solution.
Radiant said that ACIS helps manufacturers to ensure characters are legible and correctly formed, verify compliance with requirements for CE and other regulatory markings, ensure brand color and quality standards, perform product text validation, and support part traceability (e.g., confirming serial numbers).
The ACIS solution integrates a ProMetric I-series Imaging Colorimeter, a proprietary illumination configuration mounted in a metal framework, and ACIS software, which combines high-resolution imaging colorimetry measurement with sophisticated image analysis.
The company are demonstrating the new technology at the Display Week 2022 event taking place this week at the San Jose McEnery Convention Center in San Jose, California.
