油印卡片所使用的油墨一般是由颜料微粒均匀地分散在连结料中,再加入适量的填充剂、干燥剂和稀释剂而制成。连结料又是由植物油,矿物油、合成树脂以及溶剂等原料配制而成。由于油墨的这种构成特点,当我们油印卡片时,油墨中微过量的稀释剂、植物油及矿物油等易渗湮的物质,就会沿着卡片的纹理扩散,这就是我们平时所说的油墨渗出。油墨渗出的结果,使得字迹模糊、笔划不规则整齐,甚至污损卡片,破坏卡片的美观性。如果把准备使用油墨先放到一块硬纸板(不必把油墨散开,堆放着即可)——普通纸盒的纸板上,这样由于纸板有很强的吸湿性,油墨中微过量的易渗湮的物
Inks used inks are generally dispersed by the pigment particles evenly in the binder, then add the appropriate amount of filler, desiccant and diluent made. Linking material is made from vegetable oil, mineral oil, synthetic resin and solvent and other raw materials. Due to the composition of the ink, when we seal the card, slight excess ink in the diluent, vegetable oil and mineral oil and other easily infiltrated substances will spread along the texture of the card, which is what we usually say ink Exudation. Ink leakage results, making the handwriting is fuzzy, strokes and irregular irregularities, or even deface the card, destroying the beauty of the card. If you put ready to use the ink first put a piece of cardboard (do not have to spread the ink, piled up) - ordinary cardboard carton, so the cardboard has a strong hygroscopicity, slight ink infiltration Of things
