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
