Titre : Computer color match prediction, or predicament ? Type de document : texte imprimé Auteurs : J. C. Crowther, Auteur Année de publication : 1989 Article en page(s) : p. 184-199 Note générale : Appendix Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Computer color match prediction (C.C.M.P.) systems predict accurate recipes provided that all preconditions are met. The major constraint limiting wider application of C.C.M.P. is inconsistency in the substrate itself. If substrate variability is so great that each leather must be individually calibrated, the work involved in calibration dyeings outweighs the benefits of rapid recipe-formulation.
Towards limiting the variable dyebility of different substrates, the ionic-charge on three leather types was investigated by an indicator method. This permitted Iso Electric Point (I.E.P.) to be estimated. Subsequent evaluation of dyeing correlated well with the I.E.P. When the I.E.P. of the three substrates differences in build-up was greatly reduced. It is believed that this work points towards methods of standardising the dyeability of substrates and hence wider application of C.C.M.P.En ligne : https://drive.google.com/file/d/1PtrRWl6PkOwNnyuOtV3gk5IUc4DIMP8z/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=17303
