Are you really relying on visual colour assessment for your textile business? If yes, then you really need to reconsider your colour quality check process.
Human colour perception varies from person to person. Factors like difference in vision, lights of the surroundings, colour perception, colour blindness are some major and common factors that give birth to controversies and discrepancies. Advance colour laboratories are equipped with high-end instruments that not only give accurate results but put an end to all the colour related debates. There are certain practices that need to be followed while doing a colour assessment.
Requirement of closed cabinet
Textile colour matching is a crucial task, you need to do this in a confined space that assures no light interference from the surroundings. The object has a tendency to absorb the light and some part of the spectrum is reflected back to the human eyes. If too many colours are falling on an object, it would reflect some different colour instead of its original shade. This hugely increases the chances of the discrepancies. It is always advised to perform the colour matching in the confined space.
Colour matching in different lights
Every light has a different effect on the specimen. And the commonest example of this is the appearance of white colour in UV light. It appears neon green. This is experienced by every second person. So, you can clearly imagine how deceptive perception you are making by analysing the colour in just one light. Testronix’s colour matching cabinet offers 5 lights (6 lights in some models) to match the specimen to the highest precision. Two specimens might match in one light, but they may not match in other. So, it is always good to have multiple light testing using an instrument.
Angle of viewing
The placement of sample under the light is very important. The angle of shadow and angle of the incidence is very important for right visual. You must have noticed in general that shadow makes a colour to appear dark than its usual colour. If you are using a closed cabinet like Testronix’s colour viewing booth for visual analysis, keep the specimen at the angle of 30°. This makes sure that specimen reflects its natural shade to the fullest.
We can make a general perception of the colour matching theory. But if studied thoroughly, there are lots of intricacies and complexities involved. At Testronix, we are developing cutting-edge technology to solve the colour matching problems.
