| Résumé : |
In the previous chapter the manual standardisation methods were described in detail. Now let us see how the standardisations are carried out using a spectrophotometer. This is the most scientific and an accurate way to standardise the bases. A spectrophotometer certainly costs more, but it helps with its accuracy of matching the bases to get them ready for tinting data preparation. Those who can afford to buy it can certainly look forward to producing good bases that also help the quality control of the white bases when they have produced. Database preparation involves accurate preparation and then application of various paint drawdown obtained by mixing of standardised Base Paints and individual standardised colorant and in combination at various percentages on Black and White Paper. Now some insights about spectrophotometer and its usage. Spectrophotometry is a tool that hinges on the quantitative analysis of molecules depending on how much light is absorbed by coloured compounds. Spectrophotometry uses photometers, known as spectrophotometers that can measure a light beam's intensity as a function of its colour (wavelength). Important features of spectrophotometers are spectral bandwidth (the range of colours it can transmit through the test sample), the percentage of sample-transmission, the logarithmic range of sample-absorption, and sometimes a percentage of reflectance measurement. |
