PAS (Printing AI Solution)
It is a web inspection system applicable to roll-to-roll production fields, such as print
ing, paper, film, textile, and printed electronics. It detects defects of the web at high
speeds and performs repair to the defective areas.
The product can largely be categorized into four divisions: transport, tension control,
inspection and repair.
: supports bi-directional transport of web by subdividing into rewinder
and unwinder sections
② Tension Control
: ensures there is consistent control. Tension levels can be set
differently according to material characteristics and web size,
thereby minimizing the strain and damage on webs.
: Customers can select color or gray scale scan camera depending on
their inspection target. The solution is built on SUALAB's machine
vision, machine learning and super computing technology, and can
analyze image data to detect defects at about 2GB/second.
: We develop and provide repair solutions optimized for each customer's
The high-resolution inspection and AI algorithms provided by PAS enables the customer to
actively manage the manufacturing process through increased accuracy in detection and
improved tracking of causes of defects.
Full automatic scanning and two-way traversing capability enable each operator to manage multiple
machines and, as such, increase workforce efficiency.
Compared with existing testers, the PAS offers a variety of functions, thereby maximizing
the efficiency of the inspection system operation.
The camera can be changed depending on customer requirements,
but the 16k line scan camera is typically used for a 300mm web test. The optical resolution is 20㎛ x 20㎛.
Real-time Image Enhancement Algorithm
The solution allows for accuracy and precision in inspection by obtaining high-quality video of the subject even in difficult
environment such as when the subject might be in motion on a conveyor belt.
We develop and provide customized repair solutions to meet each customer’s unique needs.
Edge Position Control
The EPC system is mounted on both the rewinder and unwinder, making it possible to maintain straight Web Edge positioning.
We support multi-touch gestures and have made a concentrated placement of
an intuitive flat-style UI, enhancing the cognitive experience for the user.
User Behavior Learning Engine
Most of the inspection systems in the market are manufactured to custom-fit certain processing environments and require
algorithm adjustments and/or system customizations to accommodate any changes to the processes or product quality standards.
The SUALAB solution aims to reduce the costs related to this issue. The PAS is a next-generation inspection technology that
automatically learns the degrees of defects that need to be detected in various environments, while continuing to
improve its own performance.
GPU-based High Speed Inspection
The solution analyzes image data (2GB/sec) and detects defects in real time through optimized
algorithms and GPU-based computing.
Automatic Defect Classification Engine
The solution is a revolutionary technology that can automatically classify the identified defects,
track the causes of the defects based on relevant statistics, and actively manage the processes,
ultimately enhancing production yield.
The solution supports bi-directional transport, allowing specific repair of the defect following the inspection.
The operational efficiency is maximized when one operator manages a number of inspection systems.
The solution maintains a consistent tension level. It is also possible to set certain tension levels to best accommodate
the characteristics of the inspection subject such as material and size.
Integrated Operation Program
We’ve combined the control program and the inspection program into one,
enhancing the safety and operational efficiency of the systems.
We provide remote support to address customer inquiries and to resolve issues as quickly as possible.
