a complete non-contact color measurement and imaging

solution.

The DigiEye System

The challenge faced by sweet manufacturers

Sweets tend to have irregular or curved surface

Can have either glossy or matte appearance

They have varying degrees of opacity

They can be very small and difficult to measure

Not always a solid colour, may be multiple colours

Use of natural colourants – Stability issues

Colour Management Of Sweets

The traditional method of Quality Control has been either:Visual Assessment with uncontrolled or inconsistent viewing methods in terms of :

The Observer - subjectivity

Light Source

Angle of Observation

OR

Instrumental Measurement (Spectrophotometer / Colorimeter)with restrictions and limitation. . . .

Works well on flat, opaque objects – Very limited on curved or irregular surfaces.

Limited by aperture size, averaging the colour of the selected area.

Cannot differentiate between different colours in the selected area.

The xenon flash can be too powerful for translucent sweets. It will illuminate the sweet internally, influencing the colour measurement

The product can be distorted by the aperture

Colour Management Of Sweets

The Solution:

Digitally capturing and measuring …..

- Texture, Colour & Appearance

High Resolution - Great Precision.

Consistent and Repeatable results.

Calibrated images – Colour visualisation.

Measures colour in context not in isolation.

Colour as seen by the consumer.

DigiEye – Measuring Colour in ContextThe DigiEye System from VeriVide is different.

Colour Management Of Sweets

DigiEye is a digital colour imaging system with many proven applications in the food & confectionary sector.

Offers the ability to consistently and reliably measure colour & appearance using a non-contact method.

Characterized SLR Camera.- Recording colour data at millions of points

Calibrated Monitor & Printer.- Accurate on-screen product representation.- Colour accurate photographic images.

Enclosed ‘DigiEye Cube.- Eliminating all ambient light.- Product capture in Consistent lighting- Both Angled and Diffuse lighting.

What is DigiEye?

Measuring Sweets Using DigiEye

DigiEye does not have the aperture restrictions of a spectrophotometer

Measuring Sweets Using DigiEye

Having an image allows you to be very selective of what you measureUsing sophisticated selection tools we can measure accurate non-solid colourWe can compare colour difference between standard and batch or batch to batchMuch more representative of how the consumer will view the colour

Colour Comparison Using DigiEye – An Example

Translucent products are very difficult to assess instrumentally

The background influences the colour

Using DigiEye we can select the whole object

Software correction limits the effect of the background

This allows us to give sensible colour difference values unlike traditional instrumental assessment

Colour Comparison Using DigiEye – An Example

DigiEye software correction offers benefits for opaque samples too

Note that the sample in the top right has a texture difference

This can influences the colour

We select the standard or recall it from a database

DigiEye then compensates for the structure and return accurate difference information

Measuring Surface Distribution Characteristics Using DigiEye

DigiEye can be used to assess the percentage distribution the ‘sour sugar’ coating

This information can be used to detect any deficiencies in the coating process

We can visualise using ‘false colour’ the coverage of the sugar crystals

We can see both visually and numerically that the sample on left has insufficient coating

Measuring Surface Distribution Characteristics Using DigiEye

DigiEye can also be used to assess other surface characteristics

Here we are assessing the area that the jelly ‘yolk’ has bled in to the ‘egg white’

Again this information could tell us about production deficiencies

It was found that the coverage of the jelly ‘yolk’ was very consistent

The bleed however varied by almost 15% between maximum and minimum coverage
