DigiPix
Can you successfully colour measure all your Samples? DigiEye can!
DigiPix, part of the DigiEye system from VeriVide,successfully captures images and provides non-contact measurement for a wide variety of industries. DigiPix has been successfully used in the following industry sectors: - Food, Cosmetics, Automotive, Construction and many areas of the Textile sector; Apparel, Furnishing and Flooring
The hardware consists of an illumination cabinet, a Nikon camera with a Nikkor lens, Nikon power supply, Camera stand, a Calibration chart and a White uniformity board.
The software includes Camera characterisation, Monitor calibration, a Colour QC package enabling input/export qtx files and shade library storage. DigiPix colour measurement software, Textile profiling, Colour replace software and CIElab, CIE94, CMC and DE2000 Colour difference equations.
DigiPix provides Colour Measurement, Colour Clustering and Colour Replacement.
DigiEye’s ability, using the DigiPix software, to select and retrieve colour data from any pixel in the high-resolution image allows the measurement of very small or irregular shaped samples.
As the sample is imaged without contact any raised pile including knitwear, carpets, towelling and fleece is captured without being flattened against a measuring head.
This is illustrated with the image on the right. The appearance of the raised pile is retained in the image and the individual fibres can be observed in the natural state of the actual product.
Any subsequent colour measurement will include the appearance factors such as the shadows between the individual fibres.
To measure such a product using a spectrophotometer requires the fibres to be compacted; therefore the measurements gained are not representative of the actual appearance of the product as viewed by potential customers
Colour Measurement provides colorimetric data and colour constant spectral reflectance values for the selected areas of the image. Colour difference can be performed to compare colour areas using a choice of standard equations making DigiPix an ideal tool for Quality Control.
The image and its associated colour data can be communicated electronically using standard formats, such as qtx and spectral data, to assist discussions with suppliers and manufacturers around the world.
Once a product is imaged and measured, other functions can be performed; Colour Clustering and Colour Replacement being the most common.
The Colour Clustering technique automatically groups pixels of the same colour together and then calculates the percentage of the total pixels within the image. By measuring the proportion of different colours within an image, this feature is useful in a range of industries from measuring fabrics produced from blended yarns, carpet and carpet tile blends, concrete mixtures and most importantly food.
Leading manufacturers with the biscuit, cereal and dairy dessert industries approached us to develop this valuable feature.

A vital requirement within the food industry is the need to calculate the percentage of the different product within the composition of food, such as these examples of fruit pieces dispersed with a yogurt. |

 |
The 'Colour Clustering' technique has calculated the percentage of visible fruit as viewed, by the customer upon opening. The Plum is showing at 17.1% with the Raspberry on the right reading only 5%. |
Other important uses of the ‘clustering’ technique are to calculate the amount of bran present in a loaf of bread or to calculate the total coverage of a chocolate layer on a partially coated biscuit.
The feature is also an advantage in the meat industry to calculate the percentage of visible fat.
Colour Replacement allows a product to be viewed in different colours and the new colours to be communicated electronically to designers and buyers. Colour Replacement allows the whole of a product or specific parts of it to be changed, together with the excellent quality of image, this can reduce the time of the buying cycle as decisions on the suitability of a colour can be made without waiting for the item to be manufactured.

This has applications in many industries including textile apparel and home ware and ceramics. With the development of the new Large Area Imaging Cabinet this feature is no longer confined to small products as can be seen with the rucksack images above.
An Invaluable Tool
- DigiEye is an invaluable tool for specifiers sourcing coloured components from different suppliers within a global supply chain.
- It provides an accurate, comprehensive specification for both colour and appearance against which suppliers can assess the quality of their production batches prior to dispatch.
- The synthetic colour constant spectral curves generated by DigiEye help to ensure that all product components match in all specified lighting conditions.
