As such, the paper explored the correlation between microstructure and color reproduction, then an assessment and prediction method of color optimization based on microscopic image analysis was proposed. The experimental models were divided into 24-color plates and 4-color cubes printed by ProJet 860 3D printer, then impregnated according to preset parameters, at last measured by a spectrophotometer and observed using both a digital microscope and a scanning electron microscope. The results revealed that the samples manifested higher saturation and smaller chromatic aberration ([Formula: see text]) after postprocessing. Moreover, the brightness of the same color surface increased with the increasing soaked surface roughness. Further, reduction in surface roughness, impregnation into surface pores, and enhancement of coating transparency effectively improved the accuracy of color reproduction, which could be verified by the measured values. Finally, the chromatic aberration caused by positioning errors on different faces of the samples was optimized, and the value of [Formula: see text] for a black cube was reduced from 8.12 to 0.82, which is undetectable to human eyes. <\/jats:p>","DOI":"10.1142\/s021800142054004x","type":"journal-article","created":{"date-parts":[[2019,3,20]],"date-time":"2019-03-20T04:25:55Z","timestamp":1553055955000},"page":"2054004","source":"Crossref","is-referenced-by-count":14,"title":["Color Reproduction Accuracy Promotion of 3D-Printed Surfaces Based on Microscopic Image Analysis"],"prefix":"10.1142","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7924-7759","authenticated-orcid":false,"given":"Xiaochun","family":"Wang","sequence":"first","affiliation":[{"name":"State Key Laboratory of Pulp and Paper Engineering, South China University of Technology, Guangzhou, P.
