Introducing the Graphic-Vision GV-Spectro

Introducing the Graphic-Vision GV-Spectro

GV-Spectro- Spectrophotometer and Digital Web Viewer

The Graphic-Vision® GV-Spectro combines the power of absolute color measurement and reporting with the Graphic-Vision® Series Web Viewers’ already extensive list of capabilities. The system allows operators to program the camera’s path across and down the web, points of interest, and time to be spent at each region. This provides operators with an overview of job quality, allowing them to easily inspect the web while the spectrophotometer automatically inspects the color. The system alerts them when a color is trending out-of-spec so they can take corrective action.

Who uses it:

  • Label and packaging printers who are concerned with meeting brand color specifications
  • Printers interested in color quality on artwork without the need to print color bars.
  • Companies that don’t require 100% inspection, but still need to monitor color on line.

When it’s used:

  • To verify the color of logos and other brand assets with stringent color requirements
  • To assist in monitoring the web while it’s running at high speed
  • To monitor for any process errors that cause a job to run out-of-spec, such as mis-registration.

How it works:

The GV-Spectro captures high-resolution images from a web while it’s running, presenting them on a large monitor for the operator. This allows the operator to watch for the process errors and repeating defects that can ruin a job. The camera can be programmed to automatically scan through up to 50 points of interest. To do this, the operator simply positions the camera over the point with the included remote control, then sets that location and time to dwell at that location with only a couple of clicks.  Color measurements can be taken at any or all of these locations, allowing the operator to monitor multiple areas of interest, such as logos, graphics, or copy with ease. Readings from the spectrophotometer are displayed on an easy-to-understand interface called ChromaQA. This presents the delta E, density, and absolute color measurement reports in real time as it is pulled from the web.

System Overview:

The Graphic-Vision® GV-Spectro combines the reliability and industrial capability of the GV500 Series web viewers with the power and accuracy of Techkon’s SpectroEDGE color measurement and reporting system.

The GV-Spectro is designed to address the needs of companies subject to strict color printing requirements. It is perfect for printers who require more than just a simple web viewer but don’t quite need the power of a 100% inspection system.  Customers are increasingly demanding the best possible color accuracy from their printers, and the GV530-Spectro gives printers the tools they need to make sure they can deliver what their customers need.

Integrated flawlessly into one easy-to-use system, the GV-Spectro provides unparalleled accuracy and speed in color measurement, performing up to 3,000 scans per second, and analyzing up to 31 spectral bands (from 400nm to 700nm) of color data. The system provides a real time report of both absolute and relative (∆E) color values. Calibration is automatic, minimizing the possibility of errors during inspection.

The Graphic-Vision GV-Spectro comes standard with long life LED lighting, which provides consistent illumination across the web; advanced positioning options, including programmed positioning and combination positioning; a remote control for easy programming and control of camera positioning and zoom; 1D and 2D bar code decoding; and a 2 year warranty.

PC Industries offers online demonstrations of all their systems, often using customer samples. If you would like to schedule a demonstration to see the GV-Spectro in action, call us at 1 847-336-3300, contact us using this form.

Introducing the Guardian LSI

Introducing the Guardian LSI

LSInew

The Guardian LSI is PC Industries’ entry-level full web inspection solution. Designed for companies that don’t need to worry about tiny defects, this system provides everything needed for typical defect, missing label, and unremoved matrix detection. The system is perfect for growing companies, providing an affordable way to step up from sampling web viewers to full web inspection. If your company grows to have more demanding inspection requirements in the future, trade in the system for credit toward an upgrade.

Who uses it:

  • Printers who are interested in a low cost, full web inspection solution for narrow web applications, but don’t need to detect small defects.
  • Label printers, packaging printers, and converters
  • Any company for whom die-cutting is a part of the production process.
  • Printers who need to ensure that quality is continuous and measurable

When it’s used:

  • On the press to detect or highlight die-cutting errors that leave unremoved matrix.
  • On the press to detect and highlight typical print defects
  • On the press to detect or highlight missing labels
  • On an audit rewinder to automatically present any detected defects (missing labels, unremoved matrix, or other typical defects) for correction

How it works:

The system easily is trained to a master image. Once the image is captured, the operator simply creates an inspection box around the area to be inspected. This includes die-cuts to check for bad cuts or unremoved matrix, individual labels to verify for presence, or images to check for proper color registration.

Once the master is trained, the system automatically inspects each inspection area across the web. Inspection can be done at any speed up to the specified maximum, and during speed changes. When it detects a defect, the defect image is sent to the Defect Queue, and the operator is notified. Additional outputs can be configured to trigger a marking system so the defects can be flagged for correction later, or to control a rewinder.

System Overview:

The Guardian LSI is PC Industries’ full web inspection solution. This system provides everything needed out of the box to provide inspection for missing labels, and unremoved matrix, and other typical defects.

The Guardian LSI installs easily so you get up and running fast. Detailed instructions show how to mount the system to a press or rewinder and calibrate it for use. Both telephone and remote support are available if the installer has any questions, or schedule time for one of our technicians to assist with on-site installation.

The easy-to-use interface was designed to allow operators to set up and control jobs quickly and intuitively. Job set-up requires only a few clicks to train the master image for inspection. While the press or rewinder is running, defects are displayed in real time and are stored temporarily in the Defect Queue. On press, the operator is notified of defects on screen and through the included light stack; a visible and audible alarm that can be programmed to trigger based on specific application needs. Output controls can also be programmed to automatically trigger a marking system to flag defective labels for correction. On a rewinder, the system highlights the defect on screen and can be set up to automatically slow and stop the rewinder to and present defects for correction when they are detected.

The Guardian LSI is perfect for companies who are looking for an efficient and accurate entry-level inspection system. For growing companies, PC Industries’ trade in policy will allow you to trade in the Guardian LSI for credit toward a more advanced system during the first two years. Don’t worry about outgrowing your Guardian Inspection System®- they grow with your needs.

PC Industries offers online demonstrations of all their systems, often using customer samples. If you would like to schedule a demonstration to see the Guardian LSI in action, call us at 1 847-336-3300 or contact us using this form.

Do Not Confuse Video Inspection With CCTV Surveillance

Video inspection is not what the police do when they study the video recordings taken by surveillance cameras. Nor is the term applicable to installing cameras to record the activities of staff in your employ. Video inspection is an industrial inspection system that is used to check items being produced in order to detect flaws at as early a point in the production process as possible.

It can be used in just about any kind of industry but is particularly popular in the printing trade where high speed web offset printing presses are often employed. Other uses include the visual inspection of places where a human inspector cannot go – the inside of pipelines for example.

Why Use A Video Camera?

The aspect of sending a camera where a human could not go is part of the reason. This even accounts for its popularity amongst printers. With web offset printing, the large roll of thin material (not necessarily paper) that is fed into the printing press is known as a web. Feeding in a web, printing on it and then cutting to individual size and shape is a much faster process than feeding sheets or shapes into a press – hence the use of web printing presses when large production runs are involved. However the fast moving web has to be kept in perfect alignment during its progress through the press. It would be difficult for humans to position themselves correctly to visually monitor what is happening to the web inside the press and even if it were possible, would their attention be sharp for hours on end?

A Camera Alone Is Not Full Video Inspection

The pictures coming from the camera need to be monitored in real time so that action can be taken the instant any problem appears. Sending the video to a screen for instant playing still involves the attention span of the human watching the live pictures.

To be really effective, video inspection needs to be a complete system whereby the live feed from the camera is analysed in a linked computer. The software in that computer has been specially programmed to look for certain problems that are known to be possible in the process under video inspection. When a problem is observed, the software has also been programmed to know what precautionary action to instigate. This could range from visible warning lights and audible sirens to automatically shutting down the process – depending on the nature and severity of the problem.
