The computer measured match colors system to had received the application of certain level in home, however, the configuration technology level that inchoate computer measures match colors system is low, traversal speed is slow, the theory that absorbing the linear relation between coefficient K and scattering coefficient S and chromatic chroma to undertake assumes, with the difference with have actually certain, add manufacturing process automation to control capacity low and cause semi-manufactured goods difference to wait for an element greatly, the applied effect that makes the computer surveys match colors system is not ideal. And 3D computer measures match colors system to be able to offer reasonable prescription quickly, reduce cost of printing and dyeing; Can calculate the color change rate below different illuminant, the product that different illuminant changes and creates in order to avoid is unqualified problem; Can quick consideration gives correction recipe, improve pair of lubricious efficiency; The recipe that can undertake science is changed files management.
