印版要选用耐磨、弹性适中、质量上乘的材料，同一块版面的版材厚薄要一致，树脂版厚度不于4mm，橡皮版以6-7mm为佳。无论是用阴片菲林晒版，还是手工刀刻，版面一定要平整，字迹图案线条深度不于3mm，文字图案的排列不可过分拥挤，弧线要圆滑，粗细均匀，直线要直且流畅。印刷时油墨要适当调淡，涂墨辊的墨层不宜过厚，且辊筒的压力适中，以印刷着墨均匀，箱面印迹无明显凹痕为佳。
First of all, the plate to choose wear-resistant, moderate elasticity, high-quality materials, the same plate thickness to be consistent, resin plate thickness is not less than 4mm, rubber plate to 6-7mm. Whether it is to print with negative film or hand knife, the layout must be smooth, the depth of the lines of the handwriting pattern should not be less than 3mm, the arrangement of the text pattern should not be too crowded, the arc should be smooth, the thickness should be uniform, and the straight line should be straight and smooth. When printing, the ink should be properly diluted, the ink layer of the inking roller should not be too thick, and the pressure of the roller should be moderate, so that the printing inking is uniform and there is no obvious dent on the box surface.
切忌用增加油墨浓度，加大涂墨辊压力改善印刷效果，如此非但达不到理想的目的，反而导致版面糊墨，印刷质量更差，尤其文字较小、图案复杂、线条细腻、套印要求精度高的版面，其劣势更加明显;印刷机车速不能于800转/min，速度太慢箱面着墨不均匀，且有露现象。太快墨迹过浓，版面易糊，同时还要防止纸毛、纸屑等进入印刷机粘到印版上，如发现有纸屑粘版，要立即停机，用抹布蘸酒精擦拭干净。
It is forbidden to increase the ink concentration and increase the pressure of the inking roller to improve the printing effect. This will not only fail to achieve the desired purpose, but also lead to ink paste and poor printing quality. Especially for the page with small text, complex pattern, fine lines and high overprint accuracy, its disadvantages are more obvious; The printing locomotive speed should not be lower than 800 rpm, the speed is too slow, the ink on the box surface is uneven, and the bottom is exposed. If the ink is too fast and the ink is too thick, the page is easy to paste. At the same time, it is also necessary to prevent the paper wool and paper scraps from entering the printing machine and sticking to the plate. If any paper scraps are found sticking to the plate, stop the machine immediately and wipe it with a cloth dipped in alcohol.
印刷颜色要纯正，批量无色差
Printing color should be pure, no color difference in batch
水性油墨的优劣是关系到纸箱印刷颜色纯正、鲜亮的关键，因此在选用时要十分注意。的油墨与色标无明显差异，手感细腻、粘稠、浓度适宜加水或醇类溶剂稀释无沉淀、结块现象，用木棒搅拌无泡沫产生，与其他油墨混合配色，亲和力好，无不相溶现象，所配出的墨色纯正，无异常反映，反之不可使用。
The quality of water-based ink is related to the carton printing color pure, bright key, so we should pay attention to when selecting. There is no obvious difference between the quality ink and the color label. The handle is fine, sticky, suitable for adding water or alcohol solvent to precipitate and caking. It is produced by mixing wood without foam and mixing with other ink. The compatibility is good and the phenomenon is not soluble.
印刷时好批量一次印完，不然，即使使用的是同一桶油墨，也会出现色差。原因是原墨加水或醇类溶剂稀释后，不密封，长时间暴露在空气中，油墨中的化学成分与空气中的氧发生反应，即降了色素，同时强光对油墨也有分解作用。
When printing, it is best to print in batches, otherwise, even if the same barrel of ink is used, there will be color difference. The reason is that the original ink diluted with water or alcohol solvent is not sealed and exposed to the air for a long time. The chemical composition in the ink reacts with the oxygen in the air, which reduces the pigment. At the same time, the strong light can also decompose the ink.
防止涂布白板纸箱印刷时叠印、重影涂布
Prevent overprint and double coating when printing white board carton
白板纸在制造时，用于涂布白板的涂布液中含胶，高档白板表面还要涂少量的光蜡，所以用白板做面纸的纸箱在印刷时，印版与白板纸接触的瞬间有打滑现象。加之印版压力过重，水性油墨不易渗透，印刷后的纸箱油墨干燥慢，印刷时连续作业，印品重叠堆放，箱面即出现擦痕形成的叠印重影。
During the manufacture of white board paper, the coating solution used for coating white board contains glue, and the surface of high-grade white board needs to be coated with a small amount of polish wax. Therefore, when the cardboard box is made of white board, the printing plate and the whiteboard paper will slip at the moment of contact. In addition, the pressure of the printing plate is too heavy, the water-based ink is not easy to penetrate, the ink drying of the carton after printing is slow, the printing process is continuous, and the printed matter is overlapped and stacked, resulting in the overprint of scratch marks on the surface of the box.
要解决这一问题，油墨要用乙醇调淡，不要用水，因其不易挥发，不利油墨的干燥;印刷压力要适当减小，印刷速度不宜太快，不超过600转/min为宜。印刷机堆码前加装排风扇或通热风干燥箱面墨迹。
To solve this problem, the ink should be diluted with ethanol instead of water, because it is not easy to volatilize, which is unfavorable to the drying of ink; the printing pressure should be appropriately reduced, and the printing speed should not be too fast, and should not exceed 600 rpm. The printing machine is equipped with exhaust fan or hot air drying box surface ink before stacking.
确保套印精度
Ensure overprint accuracy
套印精度取决于设备的精密度和送纸部推纸板的调节是否平行，再者就是版面制作、装配、校正。下面就版面拼贴方面浅谈套印精度。
The overprint accuracy first depends on the precision of the equipment and the adjustment of the push board in the paper feeding section, and then the layout production, assembly and correction. Below on the layout collage on the accuracy of overprint.
印版做好后，取0.5mm厚透明聚丙烯版基一张，在其长度画一垂线，然后按待印纸箱规格，用小笔画出长宽高边线，再依样稿或样箱按生产通知单规定拼版。版面位置定位后，用水笔依印版边缘画线，之后将事先准备好的同样大小版基覆盖在画好线的版基上，精确描出所有边线(如套印三色可再画一块版基)，后按套印色别，把相应的印版用氯丁胶牢牢粘在画好的位置。然后用双面胶将印版贴到印刷机的辊筒上，版基中线与印刷机装版辊筒中线对正重合即可，只要拼版位置准确，其他客观条件满足，套印就准确无误。
After the printing plate is finished, take a piece of transparent polypropylene plate base with a thickness of 0.5mm, draw a vertical line in its length center, and then draw the long, wide and high side lines with a small pen according to the specifications of the carton to be printed, and then assemble the plate according to the sample draft or sample box according to the production notice. After the layout position is positioned, the ink brush is used to draw lines according to the edge of the printing plate. After that, the prepared version base of the same size is covered on the printed plate base, and all the edge lines are accurately drawn (for example, another plate base can be drawn for three colors overprint). Finally, according to the overprint color, the corresponding printing plate is firmly glued to the drawing position with chloroprene glue. Then the printing plate is pasted on the roller of the printing machine with double-sided adhesive tape, and the center line of the plate base is aligned with the center line of the plate loading roller of the printing machine. As long as the position of the plate is accurate and other objective conditions are met, the overprint is accurate.
