【摘要】：目的研究超四色打印機中常見的Lc與C,Lm與M,Lk與K原色和淺色雙濃度墨水映射問題。方法采用色度中明度匹配的方法,通過多項式擬合建立淺色墨與原色墨之間的映射關系,并根據不同擬合次數和不同打印分辨率進行精度對比。結果低分辨率打印(720 dpi)二次擬合后匹配點的最大色差為14.33,四次擬合后匹配點的最大色差為4.59;高分辨率打印(1440 dpi)二次擬合后匹配點的最大色差為21.60,四次擬合后匹配點的最大色差為8.72。結論四次擬合二次擬比二次擬合能夠取得更高的精度,并且低分辨率打印(720 dpi)比高分辨率打印(1440 dpi)的映射精度更高。研究包含基色和淺色的兩級顏色通道的多色分色具有重要意義。
[Abstract]:Aim to study the problem of double concentration ink mapping between LC and C / L _ m and M _ L _ k and K and light color in ultra-four-color printers. Methods the mapping relationship between light color ink and primary color ink was established by polynomial fitting, and the accuracy was compared according to different fitting times and different printing resolution. Results the maximum color difference of the matching points after quadratic fitting was 14.33, the maximum color difference of the matching points after four times fitting was 4.59, the maximum color difference of the matching points after quadratic fitting was 21.60, and the matching point after four times fitting was 21.60. The maximum chromatic aberration of the dot is 8.72. Conclusion Quadratic fitting can obtain higher precision than quadratic fitting, and the mapping accuracy of low resolution print 720dpiis is higher than that of high-resolution printing 1440dpi. It is of great significance to study the multicolor separation of two-stage color channels including primary and light colors.
