Incoming Material Print Inspection

It does not matter whether you manufacture or package pharmaceuticals, food and drink, cosmetics & toiletries, cigarettes or other high quality branded goods, ensuring that your packaging has been printed correctly, has no errors in text or graphics, and conforms to your original signed-off artwork is vital for both regulatory compliance and image. You may currently do this manually which is time consuming, may lead to operator fatigue and leaves room for errors; if you use acetate overlays these are expensive to produce. A pharmaceutical company has to archive the tested samples for 10 years which can become a huge expense on storage space. The alternative is to use a comparator such as the EyeC Proofiler print inspection system. It will automatically check all text and graphics barcodes and Braille (if required), save time, improve quality and can significantly reduce costs.


Proofiler A3 Offline Print Inspection System

The EyeC Proofiler is a sample or offline print inspection system, sometimes called a comparator, that checks for quality and accuracy of text and graphics on samples of your printed packaging material against the original proof. The samples can be labels, cartons, foil, film, patient leaflets, tubes or cans . This avoids the need for using acetate overlays a tedious process that leaves defect identification to the human being, which is a significant challenge when faced with large multi-language leaflets. It also eliminates cost of archiving tested materials since you no longer need to keep samples – everything is stored in a PDF report. Instead, the EyeC Proofiler  automatically identifies significant deviations between the signed-off proof and the print sample under test. It improves accuracy and saves a lot of time especially when checking patient information leaflets

We recommend checking a complete repeat to ensure that there are no repetitive defects which don’t show up on a single label or carton. EyeC has patented the method of checking multiple items against a single proof.

And we don’t just stop after offering a qualified product. Instead, we support our clients during that require validation by offering relevant documentation including FRS, IQ, and OQ. The Operational Qualification includes a validation chart which can also be used for ongoing periodic validation checks of the system. All EyeC products are fully compliant with the requirements of GAMP and 21 CFR part 11.

What kinds of defect does it find?

The Proofiler™, ProofBook™ and ProofRoller™ print comparators will catch content errors of any kind, such as:

• Missing or wrong text

• Missing parts of a character

• Filled in letters

• missing accent/wrong font

• Missing accents or symbols

• Missing graphical elements

• Wrong barcodes

• Wrong font

• Wrong colours


How difficult is it to use?

The EyeC Proofiler has been designed with ease-of-use in mind. If you can use a mouse and keyboard you can easily master this system. The entire process consists of three easy steps:

• Acquiring the print sample image(s) and the proof to compare against

• Automatic inspection (“Proofiling”) and grading

• Printing the report

No manual set-up is required. Die Lines are identified automatically, non-printable features (i.e. varnish areas) are disregarded automatically and all items across the repeat are automatically identified and aligned to the customer’s proof for print inspection.

We provide a level of training that ensures everyone who is required to use the system can do so with competence and confidence.

What can be inspected?


Patient information leaflets printed in tiny fonts on both sides of very lightweight stock  material represent the single most difficult challenge even for the most dedicated human proofreader. Any meaningful manual inspection may take hours to complete, especially if a variety of different languages is involved.

The EyeC Proofiler inspects and produces a report on such inserts in just minutes. Fully automatic, no manual overlay, no manual adjustment is needed. Unlike any other print inspection system on the market, it automatically suppresses artefacts resulting from the backside image bleeding through the stock material even for 35 gsm paper so it finds the tiniest deviations without overwhelming the operator with lots of pseudo-defects. Tiny fonts, any language, any alphabet, nothing gets by.

Leaflet Booklets

The Proofiler can check the print on an imposition sheet against a multi-page PDF proof, and the ProofBook can check each page against the customer proof.


Self adhesive labels are used in a host of different industries and applications. Some are very simple and low cost, others may be very intricate and have a higher intrinsic value; in both cases the EyeC Proofiler™ can be a great aid to setting up the press and ensuring stringent quality control. The first impressions are checked against the customer’s signed-off proof. The press can then be run with 100% confidence that the job will be right first time.

Cartons Sleeves

Single cartons or full press sheets can be inspected against a one-up PDF proof, even for press sheets with nested and butted items. Die lines and other non-printable features included in the proof, such as Braille points, markings for (un)varnished areas and manufacturing instructions are detected and separated automatically.




If equipped with the respective options, the EyeC Proofiler™ will automatically identify and verify printed barcodes and embossed Braille against applicable standards, all within the same inspection cycle.




Tubes Cans

The print on a tube or canister is inspected using the ProofRoller. The can is simply placed onto the rollers with no adjustment required for different diameters (EyeC patent). The item is rotated and the print is checked against the customer proof. You can be certain it’s correct. See video of ProofRoller can and aerosol inspection system







Do you just supply software or hardware as well?

Because of the complexity of selecting the scanner, computer and other components EyeC supplies the complete print inspection system not just the software.

Whether your sheet is A3, A2, B2, B1 B0 or larger, EyeC has a Proofiler print inspection system to handle it. We offer desktop scanners in A4, A3 and A2, large format pull-through scanners with 711 and 1064mm scanning widths, and floor standing large format scanners up to 2000 x 1400mm. This is not just a question of the scanner size but the quality of the scanner is extremely important; it has to have a suitable optical resolution, speed and colour reproduction. We use scanners manufactured by well established industry leaders such as Widetek, Colortrac and Cruse and all scanners used in our print inspection systems have been thoroughly tested to pass our demanding qualification regime.

Our print inspection system also has the computing power to carry out the comparison of printed sheet to proof in a reasonable time. EyeC takes great care to specify an appropriate computer to meet these needs. Typically you can expect the comparator to scan and inspect a B1 printed sheet in 2-3 minutes. How does this compare to manual proof reading!

EyeC offers a number of options for its Proofiler system; these include Braille inspection, Barcode verification and testing of other codes such as Data Matrix and Databar (RSS)
