LVS® 7000 In-line Print Quality Inspection System

The LVS® 7000 is the only Vision System on the market capable of blemish/defect detection, plus variable data, barcode reading and ISO grading capabilities.

The LVS® 7000 is a vision-based system designed to inspect print quality at line speeds for the following areas:

The LVS® 7000 is a modular system, which means that you can check the print quality for any of the aforementioned areas, or for all of the areas simultaneously depending on which software modules are purchased.

Below is a list of the available software modules:

Barcode Grade

The LVS® 7000 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. This module must be used with a monochrome camera only.

Additional supported symbologies include:

  • Aztec
  • Codabar
  • Code 128
  • Code 39
  • Code 93
  • Data Matrix
  • DataBar expanded
  • EAN-13
  • EAN-13 (2-digit supplemental)
  • EAN-13 (5-digit supplemental)
  • EAN-8
  • GS1-128
  • GS1 Databar Limited
  • GS1 Databar Stacked
  • GS1 Databar-14
  • Interleaved 2 of 5 (ITF)
  • Micro QR Code
  • MicroPDF417
  • Pharmacode - Laetus
  • UPC-A
  • UPC-A (2 digit supplemental)
  • UPC-A (5 digit supplemental)
  • UPC-E
  • UPC-E (2 digit supplemental)
  • UPC-E (5 digit supplemental)
  • All applicable GS1 composite components

Barcode Read

The LVS® 7000 decodes 1D and 2D 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. This module may be used with a monochrome or color camera.

The LVS® 7000 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. This module may be used with a monochrome or color camera.

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.

Bar Code 1D and 2D Health Check

This feature is enabled by an LVS® representative. When requested, the system can be configured for health check instead of grading. If this feature is enabled, the choices are 1D/2D (Read) or (Health check), instead of 1D/2D (Read) or (Grade). The computer reports a percentage instead of a grade. For example, instead of 3.4/06/660 (B), the computer reports 85%. The warning and passing scores are shown as percentages instead of grades. This module may be used with a monochrome or color camera.

Delta E

The Delta E Color Detection module detects color variations by comparing the trained color (also called the Golden color) to the image color currently displayed in the field of view. The Delta E module continuously calculates the average L*a*b* values of all the pixels within a sector according to CIE 2000 specifications. This module must be used with a color camera only.

RIMS

Automated Roll Inspection Mapping System (RIMS)

(designed for post press operation)

RIMS allows operators to produce their entire job including multiple roll run of labels, track every error on the job, determine at the end of the run if the quality labels meet the job expectations and then run the error changes, splicing and roll fixing in an off-line operation (rewind / slitter device).

Operation is simple - the standard LVS® 7000 is mounted to the press for main production and a simple tracking unit is installed on each of the rewind units. Simply set the unique job name for each roll produced and print the labels - the LVS® 7000 will track all of your errors and record them for later review by RIMS.
