A graph of the key parameters of color components for 10 examples of normal pallets and one defective one is also presented; it is clearly seen that the spread of parameters obeys a statistical pattern.RGB Reference Color Total Coverage, %Reference Mean Zone Coverage, %Reference Mean Zone Size, %Color Total Coverage, %Mean Zone Coverage, %Mean Zone Size, %A 248,254,250 26.02 11.03 8 7.56 0.21B 66,72,74 45 30.05 16.96 72 43.70 33.04C 238,153,90 19 15.74 3.66 20 15.64 4.56than in the case of a monocolor. For such products it is more important to control proportions of color components and characteristic sizes of zones.Color control on wet and dry sidesIt is important to consider that color standards are usually established for finished products (dry side), while operational color control is preferably carried out immediately after molding (wet side). This allows you to timely adjust the recipe if deviations occur. To do this, the system must perform a twoway conversion of color parameters between wet-side and dry-side states. It should be noted that this transformation affects the shades and has almost no effect on the proportions of colors. Thus, we can conclude that shade control, which is more important for mono colors, is more susceptible to inaccuracies in the wet-to-dry conversion. At the same time, for determining the proportions and mixtures of color mixes, this factor is less important and can be assessed even without a clear wet-dry color conversion.ConclusionDespite the obvious importance of such a parameter as the color of paving, the procedure for its instrumental control has not yet become a standard in the industry. The main reason is the technical complexity and novelty of methods for continuous monitoring of color parameters. Only in recent years has equipment appeared on the market that allows automatic and systematic recording and analysis of product color directly on the conveyor, such as QuatroPBC from Quatromatic.This article proposes objective parameters for describing both simple and complex (color mix) color solutions. As technology develops and uniform industry traditions and standards emerge, this set of parameters will be refined and supplemented. But now, with their help, it is possible to standardize color parameters both at a single plant and between plants of the same manufacturer. nFURTHER INFORMATIONQuatromatic LTD 4-8 Ludgate Circus London, EC4M 7LF, England info@quatromatic.com www.quatromatic.comCoverage (%)Color coverage (%)Zone size (%)Final statistics (Max Zone): Mean X(Cov, max)*%u00b1NStd %u0438 Coverage chosen_file=11 All files combined: Final Points (Mean Zone)Colors (R, G, B)
