Defect Detection
Benefits
- Continuous in-line automatic detection of all typical print defects saves money, reduces waste and contributes to improved customer satisfaction
- High resolution 3 chip digital camera readily identifies defects and troublesome print flaws that competitive systems miss
- Separate sensitivity settings for each type of defect allows you to effectively target, identify and eliminate the kinds of defects that are most troublesome for you
- Defect detection can be started on a new job in seconds
- Adjustable warning and alarm thresholds
- Our unique “Learn Print Variation“ function allows adaptation of the system to your kind of printing and process management needs
An Effective Tool To Manage Print Quality And Reduce Waste
PREMIUS digital 3Chip utilizes powerful algorithms which allow it to automatically detect all typical print defects such as streaks, hickeys, splash, voids, mis-register, missing type, fill-in, etc. Print quality can be effectively managed throughout the run, resulting in reduced waste and happier customers. The overall impact can often generate payback in months.
- Identifies ink splashes, missing print, voids or other color var-
iations within a homoge-
neously printed area.
- Detects even the finest or low contrast doctor blade streaks.
- Detects misregister, missing print or additional print lo-
cated within structured print areas.
- Detects fine deviations of color in both print and non print areas.
User Defined Warning And Alarm Thresholds
Adjustable warning and alarm thresholds let you decide when a defect is a defect and when it is not. As soon as the detected difference of one type of defect exceeds the preset threshold, the system displays a warning or alarm message and triggers an alarm.
Defect Detection That Is More Accurate And More Reliable
Advanced process control features combined with the superior resolution of our 3 chip digital camera mean more accurate and reliable defect detection, done automatically over the entire area. Highly sophisticated algorithms compensate for web stretch, movement, tension variations and snap-back common with extensible films providing effective defect detection on a wide variety of substrates, even 1⁄2 mil PE. Advanced Image-Lock with Global Positioning guarantees a steady image, automatically stabilizes possible image-offset and deploys a Trigger-Tracking facility to automatically correct image drifting caused by web tension variation.
Separate Sensitivity Settings For Each Type Of Defect
Unique software features allow you to determine if and when a particular defect should be flagged or defined as acceptable; or to select certain areas of the job for more or less compre-
hensive inspection. Separate sensitivity settings for each type of defect allow you to effectively target, identify and eliminate the kinds of defects that are most troublesome for you.
Defect sensivity is adjustable over a range of 0 to 100, en-
abling the system to readily adapt to different user, substrate and process control needs. Defects identified are highlighted along with their degree of severity, helping operators prioritize corrective action.
4 Times Faster Defect Detection
By using the XL field of view (XL-FOV) defect detection on the entire repeat can now be performed 4 times faster than be-
fore. The amount of material inspected is also 4 times greater. Defects are found and corrected far more quickly, resulting in less waste and greater productivity from the press. Even the smallest print defects hardly noticeable to the naked eye can be recognized with ease.
