Setting up the inspection environment

A reliable Manual Visual Inspection process starts with a suitable inspection environment. The room and equipment should allow operators to inspect products under consistent and controlled conditions.

Important elements include:

  • Suitable light intensity
  • Black and white inspection backgrounds
  • Controlled ambient conditions
  • Non-reflective surfaces
  • Practical room layout
  • Limited distractions for the operator

These elements help create repeatable inspection conditions and support consistent operator performance.

Developing inspection procedures

Clear procedures are needed to define how Manual Visual Inspection should be performed. These procedures may include inspection criteria, inspection timing, defect classification and the handling of specific defect types.

A well-defined procedure helps operators apply the inspection method consistently and gives the organisation a clear reference for training, qualification and routine inspection.

Our services include:

  1. Setting up inspection facilities:

  • We ensure your inspection rooms are compliant with Good Manufacturing Practice (GMP) requirements. This includes optimal lighting (minimum 2000 lux), controlled ambient conditions (temperature below 25°C, humidity, and noise level under 55dB) and non-reflective surfaces.

  1. Developing inspection procedures:

  • eyetec can assist in writing detailed, customised procedures for Manual Visual Inspection. These procedures may include inspection criteria, inspection timing, defect classification and guidance for handling specific defect types.

  1. Operator qualification and training:

  • eyetec provides a thorough qualification program for operators, including initial training, ongoing education and requalification. Our training kits are constantly updated with new defects to ensure operators can identify all possible issues.

  1. Experience in establishing Manual Visual Inspection departments:

  • From zero experience to a fully functional Manual Visual Inspection department, eyetec has successfully launched Manual Visual Inspection departments such as Ardena's and implemented improvement projects to enhance inspection efficiency and accuracy.

  1. Process improvement projects:

  • eyetec also supports improvement projects for existing Manual Visual Inspection processes.

    These projects may include reviewing inspection conditions, assessing operator performance, supporting PoD studies, reducing variability or adapting the inspection method to a specific product or container format.

Whether you are setting up a new Manual Visual Inspection department or reviewing an existing process, eyetec can provide practical support tailored to your situation.

eyetec test sets

To support Manual Visual Inspection training and operator qualification, realistic test sets are essential. eyetec develops Visual Inspection test sets with standardised samples that simulate relevant defects, such as foreign matter particulates.

The sets can be tailored to the container format, product characteristics and defect profile used in the inspection process. They may also include customised placebos with predefined characteristics, such as colour, viscosity, turbidity or surface tension.

These test sets can support operator training, qualification, method evaluation and PoD studies by helping operators practise and assess defect detection under defined MVI conditions.

Custom Visual Inspection Booths

Manual Visual Inspection requires consistent inspection conditions. eyetec develops Visual Inspection booths to support controlled, repeatable inspection set-ups.

The ET Inspira Visual Inspection booth is developed to provide consistent inspection conditions with attention to traceability and operator comfort. It includes a vertically adjustable black-and-white inspection panel and non-flickering LED illumination to support consistent particle inspection.

The booth is operated through a touchscreen interface and includes predefined LOW and HIGH light intensities. Built-in calibration functionality allows the light intensity to be adjusted, with settings logged to an SD card for traceability.

The vertically adjustable inspection panel helps operators position the inspection zone at a suitable ergonomic height. Enclosed side walls reduce distractions and limit lateral light ingress during inspection.

A reliable Manual Visual Inspection process depends on a suitable inspection environment, clear procedures, trained operators, representative test sets and consistent inspection conditions.

eyetec supports pharmaceutical companies and CDMOs with Manual Visual Inspection training, test sets, inspection booth solutions and process support.
