在制造手提袋前必须要对其印刷知道作必定了解，才能顺畅印刷完究竟。为了将手提纸袋制造得更精巧，印刷生产中应留意以下关键。
before making a handbag, it is necessary to know about its printing knowledge before printing it smoothly. in order to make the paper bag more skillfully, we should pay attention to the following key points in printing production.
1.调理好印刷压力
1. recuperate printing pressure
手提纸袋常常选用定量为250～400g/m2的白板纸制造，纸张比较厚，对于印刷 压力的调理提出了比较严苛的要求。调理时，印版滚筒与橡皮滚筒的中心距不变， 只需调整压印滚筒与橡皮滚筒的中心距。在印刷定量为250～450g/m2白板纸时，可 将滚筒的中心距拉大0.20～0.40mm。别的，因为白板纸外表滑润度较差，其严密程 度也远没有铜版纸好，因而，还要留意将印刷压力相应加大一点。调理印刷压力， 也可选用增减橡皮滚筒包衬厚度的办法。
the paper bag is often made of white paper with a quantity of 250 to 400g/m2. the paper is thicker, which requires more stringent requirements for the printing pressure. when adjusting, the center distance between the plate cylinder and the rubber roller remains unchanged, and only the center distance between the impression roller and the rubber roller is adjusted. when printing is 250 to 450g/m2 whiteboard, the center distance of the drum can be increased by 0.20 to 0.40mm. in addition, because of the poor smoothness of whiteboard, the degree of rigor is far from that of coated paper. therefore, we should pay attention to increasing the printing pressure accordingly. to adjust the printing pressure, you can also choose the thickness of the rubber drum.
2.调整好胶印输纸部分
2. adjust the offset printing part
印刷白板纸、铜版纸、卡纸、牛皮纸时，因为纸张定量较大，因而应将输纸部 分的吸纸嘴、吹纸嘴的风量相应调大一些；分纸吸嘴要替换直径较大、较厚的橡皮 胶圈；拉规的压簧可换成直径较大的类型，以实现进纸不摇摆、走纸平稳的意图。
when printing whiteboard, copperplate, cardboard, kraft paper, because of the larger quantity of paper, the air volume of the paper suction nozzle and the paper nozzle should be adjusted accordingly; the paper suction nozzle should replace the larger and thicker rubber apron; the press spring of the drawing gauge can be changed into a larger diameter type, so that the paper will not swing and walk. the smooth intention of the paper.
印刷白板纸时，胶印机双张操控器的空隙要相应添加，侧规和前规的压纸舌与 输纸板之间的间隔要增大一些。防止多张白板纸堵塞在压印滚筒与橡皮滚筒之间， 形成“闷车”毛病。双张操控轮与进纸辊之间的间隔不行小于2张纸厚，也不行大于 3张纸厚，不然拱曲的纸张经过期就会泊车；或许双张纸已经从操控器外表经过，而 操控器电源触电还没有触摸，起不到操控双张的意图。此外，还应及时整理双张控 制轮、进纸辊外表和电源操控处2个触电外表的尘埃或绝缘物，防止双张操控系统失 灵。
when printing the white board, the gap between the double operator of the offset press should be added correspondingly, and the interval between the press paper tongue and the paper board of the side gauge and the front gauge should be increased. prevents multiple sheets of white paper from blocking between the impression roller and the rubber roller to form a "stuffy car" problem. the interval between the double control wheel and the paper roll can not be less than 2 sheets of paper thickness and not more than 3 sheets of paper, or the arched paper will berth through expired; perhaps double paper has passed through the manipulator, and the controller&＃39;s power touch has not been touched, and the intention of manipulating the double sheets is not available. in addition, the dust or insulation of the 2 electric contact surfaces of the double control wheel, the paper roller surface and the power control place should be arranged in time to prevent the failure of the double control system.
3.防止反面蹭脏
3. prevent the reverse side from rubbing the dirty
手提袋印刷往往会有满版实地，简单形成反面蹭脏。因而，应尽量选用原桶 墨，恰当加一些去黏剂、防粘剂，不加6#调墨油，天气炎热时不要加燥油。
handbag printing tends to have a full version of the field, which makes it easy to form negative sides. therefore, we should try to choose the original barrel ink, properly add some sticky agent, anti sticking agent, do not add 6# to adjust the ink oil, and do not add dry oil when the weather is hot.
此外，还能够选用喷粉的办法来处理。但应留意，喷粉会影响印刷品的外表光 泽度，并污染环境，会把胶印机收纸等部分磨损、粘脏。
in addition, the method of dusting can also be used to deal with. however, it should be noted that dusting will affect the gloss of printed products and pollute the environment, which will cause the parts of the offset printing machine to be worn and sticky.
需求留意的是正确组织印刷色序。为了防止印迹不干时纸张彼此磕碰发生的背 面蹭脏，应首要印刷文字、线条版，再印刷实地版。
the need to be aware of the correct organization of the printed color sequence. in order to prevent the paper from rubbing against each other when it is not dry, the paper should first print the text, line plate, and then print the field version.
4.组织好印刷色序
4. organization good print color sequence
在组织印刷色序时，除要考虑反面蹭脏外，还应留意以下几点。
in order to organize printing order, we should pay attention to the following points in addition to considering the negative side.
(1) 先印网目调，后印线条、实地。当手提袋上既有四色套印的网目调图画，又有 文字、实地图画、线条时，为了保证套印准确，削减纸张弹性的影响，应首要印刷 网目调，再印刷线条、实地，并能够认准主次，先难后易。(2) 先印深色彩，后印浅色彩。因为浅色彩油墨遮盖力弱，放在后边叠印时，略微 套印禁绝，也不简单发觉，套印作用较好。 (3) 若遇到白板纸、卡纸、牛皮纸等含水量不均匀，起皱不平坦，外表强度差等引 起掉粉、掉毛时，可先打空印一道水以处理单色印刷时的质量事故。
(1) the first print of the mesh, after printing lines, on the spot. in order to ensure the accurate printing and reduce the impact of paper elasticity, the first printing of the mesh, the printing lines, the field, and the recognition of the primary and secondary, and the first difficult and easy. (2) first print deep color, then print light color. because the light color ink cover power is weak, when placed behind the overprint, slightly overprint is prohibited, nor is it simply found that overprint is better. (3) if the water content of whiteboard, cardboard, kraft paper and so on is uneven, wrinkling is not flat, and the appearance strength is poor, when the powder and hair fall are caused, a water can be printed in order to deal with the quality accidents of monochrome printing.
