摘　　要：在同一印刷条件下,对不同纸样利用IGT适性仪印刷,通过测量印后主密度及L*a*b值,研究了纸张平滑度、吸墨性对其印后的光密度及色域的影响.结果表明:K&N值越高,D∞越大;平滑度越大,纸张系数m越大,达到饱和密度D∞所需墨量越小;平滑度大,吸墨性好,纸张吸收油墨均匀,色彩呈现效果越稳定,色域较大,但会出现不同程度的色彩缺失.Under the same conditions, samples were printed by IGT appropriate printing instrument, then measured its optical density and L ＊ a ＊ b numbers. Analysis the influences of paper smoothness and ink absorption on optical density and color gamut of paper printed. The results showed that at a higher K＆N number, D∞ will be higher; smoothness degree is higher, then the value of m is higher, ink needed to saturated density was less; higher smoothness and better ink absorption made paper absorb ink more uniformly, more stable color retention but bigger color range. Color missing would occur in some degree.
