The demand for higher quality printed matter is rising. This has seen an increasing number of instances in which entire print runs have met with complaints or have even been completely rejected due to the fact that an order has been processed with no quality control system in place. Checking printed material manually is by no means a comprehensive solution and in view of the cost considerations certainly does not guarantee a 100 per cent level of quality control.
Each inspection system within the VISION EXPERT 4000 series can be deployed to monitor each of the stages involved in the processing of printed materials and is flexible enough to be adapted to the specific set-up: from sheet-fed printing, to rotary printing presses, rewinders or other types of processing machines . In each individual case the integration of the inspection system will be tended to by our specialists.
VISION EXPERT 4000 captures the printed matter with cutting-edge imaging technology. Irrespective of the printing methods and format, the images seized are always geometrically precise, of the highest quality and are verified for errors in real-time. Even the most minute of errors are reliably identified before they turn into a problem. The printed matter can be examined using a resolution of up to 0.01mm² (depending on the system in situ, machine type and print theme). It is also possible to simultaneously inspect face and reverse printing output.
The following are among the printer errors the VISION EXPERT 4000 recognises:
- Colour changes: subtle colour deviations, colour differences from Delta-E 3, completely or partially missing colour, mistakes in colour gradients, smears, blotches, splatters, bleeding
- Clouding of printed matter
- Stripes, streaks, dirt
- Hickeys, shades, smudges, water drips
- Incorrect text: missing, blurred or incomplete characters, erroneous or missing sections of text (with PDF module), missing symbols, errors in foreign languages (such as Japanese, Arabic), character error
- Incomplete or missing print
- Missing labels
- Register errors or fluctuations
- Lacquer is either wholly or partially missing (with UV brightener and UV inspection module)
- Punching errors: punching remnants, kiss-cut text
- Inaccurate barcodes
- Mistaken printing
- Flaws in foil finishing
- Registration deviation
