中文摘要:
      目的 研究不同参数下珠光颜料在水性光油中的显色效果。方法 将珠光颜料均匀分散加入到水性光油中,在胶印色样表面进行上光涂布,测量上光前后色样的色度值,计算色差,研究珠光颜料质量分数和印版加网线数对其呈色效果的影响。结果 黄绿、蓝色、金色这3种珠光颜料的主密度和色差都随着质量分数的增加而增大;相同质量分数下,5~25,10~60,40~100 μm 3种粒径大小的青色颜料分别对应凹印版辊70,60,50 lpi/cm加网线数时,颜色的主密度和色差值最大。结论 研究表明质量分数是影响珠光颜料显色效果的最主要因素,颜料的粒径大小和凹印版辊的加网线数相匹配时珠光颜料的显色效果最好。
英文摘要:
      The work aims to study the color rendering effect of pearly pigment in the water-soluble varnish under different parameters. The pearly pigments were uniformly dispersed into water-based varnish, and printed on the offset color sample. The chromatic values of color sample before and after printing were measured to calculate the color difference. The effects of pearly pigment mass fraction and plate screen lines on its color rending effect were studied. The main density and color difference of three kinds of pearly pigments (in yellowish green, blue and gold) increased with the increase of mass fraction. Under the same mass fraction, when the indigo pigments of three particle sizes (5~25, 10~60 and 40~100 µm) respectively responded to the gravure rollers with 70, 60 and 50 lpi/cm screen lines, the main density of the color and the color difference were the largest. The study indicates that, the mass fraction is the most important factor that affects the color rendering effect of pearly pigment. When the particle size of the pigment and the screen lines of the gravure roller are matched, the color rendering effect of the pearly pigment is the best.
