摘　　要：基于GMG和CGS色彩管理软件对数码打样质量的影响进行研究,比较打样纸张未经过色彩管理和分别经过GMG、CGS色彩管理的质量差别,同时比较两款软件打样性能的优异性.结果表明:经过GMG和CGS色彩管理之后,数码打样纸的色域扩大,色彩再现和阶调复制能力显著提高,印刷相对反差值增大,网点扩大减小,整体打样质量较好;就两款软件的比较而言,CGS比GMG色彩校正过程更简捷和准确,在色彩再现、阶调复制、减少网点扩大方面表现更突出,打样质量更高.The impact of GMG and CGS color management software on the quality of digital proofing was studied and compared.The performance of proofed paper was also compared that without color management.The results indicated that the gamut of digitally proofed paper was expanded,the color reproduction and tone reproduction both significantly improved,the relative contrast value was increased,the dot gain was reduced and the overall proofing quality was better than without GMG and CGS color management.The comparison between the two software shows that CGS is simpler and more accurate than GMG during color correcting process and performs better in color reproduction,tone reproduction and dot gain reduction,and thus can provide better proofing quality for digital proofing.
