Advantages

High-precision mark color recognition
In the color mode of GCs111, LEDs of three colors (R, G, B) are used simultaneously to identify
the color of the color code according to the RGB ratio. High-precision
judgment can be achieved.

Color mode high precision discrimination
Using LEDs of three colors (R.G.B) at the same time, the color of the color mark can be determined with high precision based on the R.G.B ratio of the reflected light.

High-speed response to improve production efficiency
1. Color mark mode ultra-fast response
2 . Automatically selects one of three (RGB) LEDs (single color) to achieve a detection mode of
45 ps ultra-fast response.
3 . The optimal LED automatic selection function automatically selects the most suitable LED for
detection. Best suited for high-speed inspection.

Garantta GCS111 Mark Color Sensor Solutions
Success Story 1: Printing Industry - Solving the Color Difference Detection Challenge for Packaging Boxes
Client: Wanchang Printing & Packaging Group
Challenge: The company relied on manual visual inspection of printed colors on packaging boxes on its production line, resulting in low efficiency (inspection speed less than 200 pieces/minute). Fatigue and subjectivity led to a monthly color difference defect rate as high as 2.5%, resulting in high customer complaints and rework costs.
Garantta Solution: We customized and deployed the GCS-111 intelligent color sensor array for them. The sensor, through its "one-click learning" function, quickly inputs the RGB data of standard color samples and utilizes its ultra-high-speed 45-microsecond response time to perform real-time, non-contact color comparison on every packaging box passing through the production line.
Results:
1.300% Increase in Inspection Efficiency: Production line inspection speed was stably increased to 800 pieces/minute.
2.Significantly Reduced Defect Rate: The color-related defect rate was reduced from 2.5% to below 0.1%, reducing waste by more than 500,000 pieces annually.
3.Zero Complaints Achieved: Product color consistency was highly recognized by end-brand customers, achieving zero color complaints for 12 consecutive months.
4.Short Investment Recovery Period: Due to savings in material and labor costs, the equipment investment was recovered within 4 months.



Success Story Two: Textile Industry - Automated Fabric Color Sorting
Client: Jiangsu Shayin Group
Challenges: Dyed fabrics needed to be sorted into different batches based on subtle color differences (difficult to distinguish with the naked eye). Traditional methods relied on experienced workers, resulting in slow sorting speeds, high labor costs, and difficulty meeting the stringent color grading requirements of overseas customers.
Garantta Solution: We installed GCS111 high-precision mark color sensors (color modes) at key nodes of their sorting line. The sensors accurately determine the color category of each piece of fabric based on a set RGB ratio tolerance and trigger pneumatic devices to sort it to the corresponding area. Their IP67 protection rating effectively resisted fiber dust and humidity interference in the workshop.
Results:
1. Sorting Accuracy >99.9%: Fully met the customer's requirements for precise color grading. Labor costs reduced by 70%: 80% of previous manual sorting positions were replaced.
2. Production efficiency increased by 150%: The overall operating speed of the sorting line more than doubled.
3. Winning high-end orders: Successfully becoming a designated supplier for an international fast-fashion brand thanks to stable and reliable color quality control capabilities.
