No.1 Testing Instruments Manufacturers and Suppliers
Colour is the first thing attracts or repel the buyers. Quality managers often use colour measuring devices like portable spectrophotometer to keep the colour consistency throughout the production line. Companies often have strict colour specifications when it comes to branding and no discrepancy is tolerated as it may change the perception of the consumer. Therefore, colour quantification is done at the production level, so that it does not affect the sales and promotions.
On the other hand, the consumables packed inside these attractive packaging should have a consistent colour scheme. Take an example of tomato ketchup of some ABC brand. The same colour is being produced since years. Irrespective of the qualities of tomatoes, they manage to deliver consistent colour. Similarly, juices, cold drinks, candies, chocolates, wafers, etc. unbelievable uniformity you get to see.
Although a visual inspection can be done to evaluate the quality of the raw material or of end products, there are disadvantages associated with it.
Colour measurement instruments like spectrophotometer and colorimeters are largely used to keep the consistency in the production line, be it paper, plastic or medicine itself. These devices are highly capable of highlighting even the tiniest of the difference discrepancy in the packing. It actually quantifies the data and alerts the quality managers whenever there is a colour shift in accordance with the human tolerance to the change. These colour checkers detect any colour defect in the packaging prior to rolling out in the market. They help a lot in managing and maintain the quality of the final product.
Thus, you need a system that can do the colour measurement without any external disturbances. Colorimeters and spectrophotometers are the devices which can do the measurements accurately without getting affected by surroundings. Colorimeters use samples to measure the master colour with the sample colour and quantifies the differences. Testronix offers a wide range of colorimeters to do the task with variable apertures and illumination, depending upon the application.
One defined wavelength is used to measure the colour difference and thus we can say that ideal measurement conditions do not change. The range of the colour spectrum is changed into numeric values that are accepted internationally. Apart from measuring the difference, it can successfully be used for comparing two test samples, the strength of colour, colour sorting and colour fastening.
Apart from this, these range of colorimeters can help in determining the effect of environmental conditions like heat, light and water on the appearance of naturally grown products e.g. spices.
