LVS® 7500 Label Inspection System
The ultra-compact unit is the latest in vision technology offered by Label Vision Systems. This tiny, high resolution camera system mounts to the face of any thermal printer and allows the user to accurately ISO grade any 1D & 2D barcode, perform Optical Character Verification on variable text data and pattern match for blemish or print defects. The LVS® 7500 is the only Vision System on the market capable of blemish/defect detection, plus variable data, barcode reading and ISO grading capabilities. The LVS® 7500 is a vision-based system designed to inspect print quality for the following areas:
- Barcode Read (Barcode Validation) of 1D and 2D codes
- Barcode Grade (Barcode Verification to ISO/IEC Standards) of 1D and 2D Codes
- Optical Character Recognition (OCR)
- Optical Character Verification (OCV)
- Master to Label Comparison (Blemish Detection)
- Fits to any Thermal Transfer Printer
The LVS® 7500 can be installed and calibrated very fast and works with an user-friendly software interface that will allow you to start inspecting your labels from the first day. Below a list of the included capabilities:
Barcode Grading
The LVS® 7500 decodes 1D (linear) and 2D (two-dimensional) codes (including ECC-200 Data Matrix, Composite, QR Code, PDF-417 and Micro PDF) and determines if the code is “readable.” No attempt is made to grade the codes according to any standard.
Barcode Verification
The LVS® 7500 decodes and grades 1D and 2D codes (including ECC-200 Data Matrix, Composite, QR Code, PDF-417 and Micro PDF symbologies) according to the internationally accepted rules of the applicable symbology specifications and ISO 15415 and 15416. See additional supported symbologies in the above section entitled “Barcode Read.” This module must be used with a monochrome camera only. The LVS® 7500 displays a “real-time” graph indicating the overall ISO grade. This allows the operator to see trends in print quality for several hundred labels that were just inspected. When an error is detected, the “real-time” graph will change color. The system can also be programmed to “stop the press” when an error occurs; the appropriate hardware must be purchased for this feature.
Optical Character Recognition (OCR)
Unlike the OCV Module, this module is able to “read” characters and report the data content. This data is typically variable and the content remains unknown until it is read. It is important to note that the system can be trained to know what to expect for every character position. In other words, the software can be instructed what to expect: alpha, numeric, or special characters. This is called “Field masking” and will be explained in detail later. This module may be used with a monochrome or color camera. There are many fonts used in the printing industry. This system is designed to learn new fonts as necessary.
Optical Character Verification (OCV)
The human readable characters are verified at very high press speeds. The OCV module ensures that a string of sequential characters are read and or verified against a known field or database. In other words, you tell the software what should be there and the software will report if it was actually there. It will also return a percentage score as to how well it matched to the trained character.
Blemish Detection
This software module is capable of detecting a multitude of print faults from skewing and smears to missing information. These algorithms also include a “variable image data” function which accounts for variable image data within a pattern-matching zone and does not report them as blemishes. All of this inspecting is completed at press speed. This module may be used with either a monochrome or color camera.
