你知道在印刷中托墨是怎么回事吗?

今日咱们就来讲讲印刷中,拖墨是怎样回事,再解说那个之前,咱们先来讲讲什么是印刷,印刷就是把文字、图画、照片等原稿经制版、施墨、加压等工序,使油墨搬运到纸张、织品、皮革等材料外表上,批量仿制原稿内容的技术。
Today, let's talk about what is ink-dragging in printing. Before explaining that, let's talk about printing. Printing is to transfer ink to the surface of paper, textiles, leather and other materials through plate-making, ink-applying and pressure-pressing processes, and to copy the content of the original manuscript in batches. Technology.
简略含义上说,印刷是运用印版或其他方法将原稿上的图文信息搬运到承印物上的工艺技术,也可以理解为运用模拟或数字的图画载体将呈色剂/色料(如油墨)搬运到承印物上的仿制过程。这就是对印刷的解说,但在印刷过程中可能会有拖墨的现象,那么拖墨又是怎样回事呢?下面咱们来介绍一下拖墨是怎样回
Simply speaking, printing is a process of transferring graphic information from the original manuscript to the printer by plate printing or other methods. It can also be understood as the imitation process of transferring the colorant/color (such as ink) to the printer by analog or digital picture carriers. This is the interpretation of printing, but there may be ink-dragging phenomenon in the printing process, so what about ink-dragging? Now let's introduce how to return the mop ink.
印刷过程中会出现许多的问题,例如:堆墨:油墨或其他物质沉积在墨辊或橡皮布上,构成浮雕状的沉积物,影响油墨和印迹搬运。脱墨:金属墨辊受湿润液侵蚀发作氧化而排斥油墨的现象。重影:在印刷品上同一色网点、线条或文字出现的两层概括。反面粘脏:印在承印物上的印刷油墨,粘在另一印张的反面,造成蹭脏。

There are many problems in the printing process, such as: ink stacking: ink or other substances deposited on ink rollers or rubber cloth, forming relief deposits, affecting ink and print handling. Deinking: The phenomenon that metal ink rollers are oxidized by wetting solution and repel ink. Duplicate: A two-tier summary of dots, lines, or words of the same color on printed matter. Reverse stickiness: Printing ink printed on the substrate sticks to the opposite side of another sheet, causing dirty rubbing.

透印:印在纸张上的图文在反面可见等等。这些都是一些简单出现的问题,那么,印刷中拖墨又是怎样一回事呢?
X-ray printing: The pictures and texts printed on paper can be seen on the reverse side, etc. These are some simple problems, then, what is the matter of ink-dragging in printing?
当咱们选用乙酸乙酯作为胶黏剂的稀释剂时,乙酸乙酯对于常用的氯化聚丙烯油墨、聚酯油墨都是良好的溶剂,油墨部分在涂胶过程中可能发作类似于印刷中“咬色“毛病当胶液工作浓度过低(亿酸乙酯比例大),则在涂胶时乙酸乙酯对油墨的溶解就越凶猛。
When we choose ethyl acetate as the diluent of adhesives, ethyl acetate is a good solvent for common chlorinated polypropylene ink and polyester ink. In the process of gluing, the ink part may suffer from a "biting" problem similar to that in printing. When the working concentration of the glue is too low (the proportion of ethyl billionate is too large), it will be used in gluing. Ethyl acetate dissolves ink more fiercely.
别的,拖墨与胶液分裂搬运时的黏性有关,胶液的黏性越大,越简单出现拖墨现象。速度慢,则胶液滋润墨层的时间长,简单导致拖墨现象。

In addition, the dragging ink is related to the viscous property of the splitting and transporting of the glue. The greater the viscous property of the glue, the simpler the dragging ink phenomenon appears. Slow speed, then the glue moistens the ink layer for a long time, which simply leads to the phenomenon of ink dragging.
