How do you inspect packaging of bottles, cans and cylinders

Cans and bottles

Packaging and labelling are driven by a number of factors. First, you have the ergonomics of the package, ensuring that the object is packaged properly ensuring protection, convenience, and the proper message is communicated.

Another key factor is its market appeal, the artwork, the colors, fonts that companies use directly influence sales. There is truly a science behind it. However, it is important to ensure that there are no errors, because no matter how pretty the package is, consumers will not buy any goods that are mislabeled.

An error in labelling is the number one reason why products are recalled. Companies have paid millions of dollars in fines and penalties to recall products for simple product mislabeling; in fact, the average cost of a product recall is between 5 – 10 million dollars. Finally, the damage to a company’s reputation can be immeasurable and could amount to a company failing.

How do you inspect a label printed directly onto the can, tube, etc.?

To ensure the package is error free, progressive companies now use automated proofreading solutions throughout the design and printing of the package and label. In fact, for every phase of the packaging workflow, a different proofreading solution can be used for inspection purposes anywhere from text and artwork inspection through to barcode and braille verification.

To inspect a printer proof versus the approved artwork is a relatively straight forward job and done by most printers before completing the entire press- run. A sample of the printed piece is first scanned with a Roll or Flatbed scanner then uploaded into a print inspection solution like ScanProof by GlobalVision, where it can then be inspected. Packaging that can be laid flat, such as labels and folding cartons, pose little problem. However, until recently, packaging that is cylindrical poses a unique challenge to printers and their customers.

In the past what companies would do is cut cylindrical containers such as cans and tubes, try to get it flat as possible lay it on a flatbed scanner. This posed a few problems, the first being that you can never really get the sample container flat enough, secondly, it is very time-consuming and can be a little dangerous. Also, you can severely damage or at a minimum shorten the scanners life.

Scan360 further enables users to scan and inspect with great accuracy:

  • Large heavy-gauge metal cans

  • Embossed text
  • Rough textured plastic finishes
  • Shrink wrapped cylindrical items
  • Aluminum cans
  • Glass jars
  • Plastic bottles
  • Soft metallic containers
  • Polymer tubes

With so many regulations affecting pharmaceutical and CPG companies, the need to ensure packaging accuracy has never been greater. With Scan360, even printed cylindrical items can be effectively and rapidly inspected, safeguarding against errors, reprints product recalls and the accompanying financial loss.
