柔印油墨成本应该怎么控制?

  采用水性油墨对薄膜材料的附着力,与UV油墨相互叠印附着力。首先,需要选择合适的水性油墨,使其能够附着在薄膜材料的表面;第二,关注水性油墨材料的链接或任何积水是否可以用UV油墨叠印匹配,如果没有重叠或UV油墨叠印后附着力不好,要考虑在打印一个特殊的涂层,以确保质量的叠印,表面或印刷水性油墨、UV油墨签署将经不起3 m胶带测试。

  The adhesion of water-based ink to film materials and the overlapping adhesion with UV ink are adopted. Firstly, we need to choose the appropriate water-based ink to make it adhere to the surface of the film material; secondly, we should pay attention to whether the links of water-based ink material or any accumulated water can be matched by UV ink overlay. If there is no overlap or the adhesion of UV ink after overlay is not good, we should consider printing a special coating to ensure the quality of the overlay. Surface or printing water-based ink, UV ink signature will not withstand 3 M tape test.

  控制油墨压力与印刷压力之间的关系

  Controlling the relationship between ink pressure and printing pressure

  如果使用UV油墨印刷,印刷压力稍高,标签的质量也不会太大。但如果使用水性油墨印刷,印刷压力大,文字边缘容易产生“野墨”、脏、毛刺等问题。如果它导致不必要的浪费,所得到的就不值得失去。

  If printing with UV ink, the printing pressure is slightly higher, and the quality of the label will not be too large. However, if water-based ink is used for printing, the printing pressure is high, and the edge of the text is prone to "wild ink", "dirty" and "burr" problems. If it leads to unnecessary waste, the gains are not worth losing.

  考虑产品过程的成本

  注意两层印刷和一层印刷的区别

  Note the difference between two-layer printing and one-layer printing

  通常,在大田印刷中,大多数标签印刷公司都会使用双层油墨,这样可以避免产生脏点。其实这样做还有另一个原因:在同样的色彩密度下,使用两种薄墨比一种厚墨好。

  Typically, in field printing, most label printing companies use double-layer ink to avoid dirty spots. In fact, there is another reason for this: under the same color density, using two kinds of thin ink is better than one kind of thick ink.

  需要注意的印刷油墨较厚,油墨平整度通常不佳,易花、假花,看上去颜色较浅。如果使用铜版纸印刷,油墨渗透会加剧这种现象;但是当两层油墨印刷,不是这种情况,个印刷油墨通常是更薄,除了可以带走基质上的脏点,也可以填补这个空白基质或不均匀,表面后再第二油墨,印刷领域的印刷效果会更光滑,仪器测量密度值会更高。

  It should be noted that the printing ink is thicker, the smoothness of the ink is usually not good, easy to flower, false flowers, and looks lighter. Ink penetration will aggravate this phenomenon if printed on copperplate paper, but when two layers of ink are printed, it is not the case. The first printing ink is usually thinner. In addition to removing dirty spots on the matrix, it can also fill the blank matrix or uneven surface, and then the second ink, the printing effect in the field of printing will be smoother. The density value measured by the instrument will be higher.

  确定是否需要上釉

  Determine whether glazing is required

  上光有两个目的:一是增加标签的光泽度,二是保护标签不被磨损。如果只是为了增加光泽度,柔印油墨本身就有一定的亮度,所以不需要发光。如果是为了保护标签,有些标签在运输和使用中可能没有磨损,不需要打磨。如果不考虑实际情况,盲目选择上光工艺,则会导致不必要的轻油损耗。虽然油不朱比一般油墨便宜,但油不朱经常被涂满,而且涂膜较厚,所以使用时浪费大量。

  There are two purposes of polishing: one is to increase the gloss of the label, the other is to protect the label from wear and tear. If only to increase gloss, flexographic ink itself has a certain brightness, so there is no need for luminescence. If it is to protect labels, some labels may not wear out during transportation and use, and do not need to be polished. If the actual situation is not considered, blindly selecting the polishing process will lead to unnecessary light oil loss. Although ink is cheaper than ordinary ink, ink is often coated with thick film, so it is wasted a lot in use.

  因此,在工艺设计的初期需要考虑,如是否需要上釉,或者是否需要全板上釉。如果贴标时附在标签上的位置、运输、使用过程中不发生摩擦,那么,对于超透明标签就不能进行抛光。如果是不同的标签,因为它需要模切面积大,那么就不需要整版上光,只需要局部上光。对于需要抛光的零件,还需要考虑轻质油层厚度,满足客户要求。对于标签的耐磨要求,有必要保证足够的轻质油厚度,有时甚至需要在轻质油中添加一些耐磨添加剂。总之,满足客户的需求就足够了,不需要高品质和高成本,不必要的工序反而会造成资源的浪费。

  Therefore, in the early stage of process design, we need to consider whether glazing is necessary, or whether full-board glazing is necessary. If the position attached to the label, transportation and use do not occur friction, then the ultra-transparent label can not be polished. If it's a different label, because it needs a large die-cutting area, then it doesn't need a full-page polishing, only a partial polishing. For the parts that need polishing, we also need to consider the thickness of light oil layer to meet customer requirements. For the wear-resistant requirements of labels, it is necessary to ensure enough light oil thickness, and sometimes even need to add some wear-resistant additives in light oil. In short, it is enough to meet the needs of customers, without high quality and high cost, unnecessary processes will result in waste of resources.
