plastics container surface fault/failure troubleshooting fault/failure formed and countermeasures printing 图线边缘缺 loss (1) more new rear 未进行处理, due to new surface type property very high, ink very difficult to surface upper. use 汽油清洗胶头, use 浸含汽油 soft pressure semi small 时. as must heavy, need loss bad 胶头. (2) ink viscosity large, make ink from toward 胶头 转移 property can defect. add amount solvent agent, dilute ink. (3) solvent agent drying speed degree fast. add slow dry solvent agent or adjustment upper plant/unit, shrink short ink in in time. (4)胶头 upper rise speed degree slow, make ink property can decline. 应适当 adjustment upper rise speed degree. (5)胶头 端面曲线 于平缓. use 端面曲线 comparison 尖 胶头. (6)凹版 in ink coating 布 不充 separation. 应检查 and adjustment ink coating sheet/plate 安装位置. (7)凹版 deep, ink drying slow. use fast dry solvent agent or use shallow 一 凹版. (8)胶头 surface fatigue hard 化. more 换胶头. in printing in need 卸换胶头时, in solid sheet/plate upper as upper 记号, 否则, 胶头位置 改变, make printing unstable. in addition, machine rear need machine gas pressure drop lower, 否则胶头会 decline, has can can to parts or upper loss 伤胶头, and surface, lower pressure in 空文字 upper ink 渗出(1)胶头端面曲线太尖. use 端面曲线 relatively is 平缓 胶头. (2)胶头太 small, 导致胶头 in upper slip 移. use relatively large specifications 胶头. (3)凹版 use time long, 文字边缘 and ink 刮刀接触 部位 abrasion loss or 凹版边缘尖部 abrasion consumption. use new printing upper ink 渗出(1) ink for ink defect. 应适当 add large pressure. 若刮刀 already abrasion loss to 一定程 degree 时, and more 换. in as process in, for ink use attention/notes below/following 几点: ①若 use new ink 刮刀, can use 150*砂纸 or 油石研 abrasion, make 刀刃端部略 formed 圆弧形; 否则, 刃口锋利, upper 崩落 飞刺会 mixed ink or 侵入凹版 in, generate printing defect. ②施 add in upper pressure amount small is 宜, this can long and lifespan, but also printing 效果也 comparison good. ③ in printing large color block or use ink 刮刀时, use micro 调式刮刀夹持 device, 以便于刮刀 adjustment. ④停 machine rear, ink 洗净, upper coating upper anti 锈油. (2)胶头 separation lower pressure. use 端面曲线平缓 胶头 or soft/flexible printing surface has fine filament ink viscosity high. add solvent agent dilute or use slow dry type solvent agent. in as process in, for/regarding ink use and tube/pipe attention/notes below/following issues: (1) new ink rear, material 呈游离状时, separation 搅拌. ink rear fast use 完. (2)当操 as ring conditions or printing speed degree 改变时, 应适当 adjustment solvent agent add amount, or use drying property can different ink or solvent agent. (3) in printing process in, due to ink in solvent agent 会不断挥发, 应适时停 machine solvent agent, separation uniform. (4) due to gas in and upper 附 杂质会不断 mixed ink in, therefore, ink in ink use rear 应进行 more 换. (5) ink rear, 应存放 in light 通风处
