Information about the measurement of colour: Because there are certain problems defining the different colours only with human eyes, the colour meter helps to identify different shades of colours. In our days, it gets more important to have proper colours. The colour meters help to get over the debility of the human eye. From this it follows that quality assurance is improved a lot by colour meters. Different colour spaces are classified by a coordinating system in which all of the different colours are represented by coordinates on an axis. Conditioned by the structure of the human eye and taking into account that it will be a human eye observing the colour, these colours are then placed on an axis. They are used in some 30 systems of colour spaces. The images above show the most important colour spaces. A fundamental problem of adjusting colours, in developing colour meters, is the sensitivity of the human eye. The problem is that the colour spaces don't coincide with the perception of the human eye. When colours are mixed, problems exist in the perception of the area for the colour yellow. On the other hand, with a mix of colour dominated by the colour blue, you can simulate a lighter shade of colour to the human eye. To eliminate such problems they are used in conjunction with a colour analysis frequency in such a way as to fabricate different shades. The manufacturer of a product sends a product out to be painted or treated having agreed on using an established colour standard (such as RGB colour space), both possess the same colour meter. The factory, follows the agreement, verifies the test output of the colour of the product and ships it as it meets the standard. They then continue with treating the product then check it against the frequency of its colour when it arrived. In cases where the result is contrary to the agreement, the two departments can communicate exactly about the difference in colours and use the same colour space in corresponding tests. Compared to a densitometer a colour meter / spectral photometer does not only measure the reflection of a colour by using a specific filter which allows to form a conclusion about the thickness of the coating of the object that has been coloured. Actually a colour meter measures the values of remission by illuminating the whole area of measurement with the whole spectrum of visible light which ranges from infrared to ultraviolet. Such spectral photometers divide the whole spectrum of visible light in a number of different ribbons or measurement flumes and delivers for each measurement flume a digitalized value of luminosity. |
