印刷品墨色不均匀的原因

文章作者:华政印务 发布时间:2022-08-11
随着印刷技术的发展,印刷工艺也变的越来越丰富。但是印刷中会出现印刷品墨色不均匀,是什么原因导致的呢?
With the development of printing technology, printing technology has become more and more abundant. But in printing, the ink color of printed matter is not uniform. What is the reason?
1.有时人为的疏忽可能会导致换橡皮布时衬垫纸压力测量不准确,这种情况对于印刷一般活件影响并不大,但大平网活件很“娇气”,任何一点调节不当都会直接反映在印品上。为此,我们更换新的衬垫纸后重新开机印刷,但印品墨色不匀现象依然存在,故此种原因排除。
1. Sometimes, human negligence may lead to inaccurate measurement of the pressure of the backing paper when changing the blanket. This situation has little impact on the printing of ordinary moving parts, but the large flat screen moving parts are "delicate", and any improper adjustment will be directly reflected on the printed products. For this reason, we started printing again after replacing the new backing paper, but the uneven ink color of printed products still exists, so this reason is eliminated.
2.仔细观察纸张后发现纸张靠身部位的布纹比靠外的粗糙,布纹涂布不匀,当以45°视角侧面观察时,涂布不匀现象十分明显,于是将纸张掉头后印刷,发现墨色不均部位转移到另一侧。由此可以判断产生印品墨色不匀现象的主要原因是纸张布纹涂布不匀,于是联系材料科更换纸张后,墨色不匀现象立即消失。
2. After careful observation of the paper, it was found that the cloth pattern on the side of the paper was coarser than that on the outside, and the cloth pattern was unevenly coated. When viewed from the side of 45 ° angle of view, the unevenness was very obvious, so the paper was turned around and printed, and it was found that the uneven ink color was transferred to the other side. Therefore, it can be judged that the main reason for the uneven ink color of printed products is the uneven coating of the paper fabric. Therefore, after contacting the material department to replace the paper, the uneven ink color immediately disappeared.
3.橡皮布使用时间过长易发生老化现象,或者因一些部位长时间被压致使橡皮布压力不匀,都有可能导致印品出现墨色不匀现象。于是,我们更换了一块新橡皮布后重新开机印刷,但故障仍然存在,故此种原因排除。
3. If the blanket is used for a long time, it is prone to aging, or some parts are pressed for a long time, resulting in uneven blanket pressure, which may lead to uneven ink color of printed products. Therefore, we replaced a new blanket and started printing again, but the fault still existed, so this reason was eliminated.
以上就是印刷品墨色不均匀的原因,另外印前设备大部分是由先进的电气元件和集成电路组成,对温度和湿度特别敏感,过高和过低的温度与湿度都会影响设备的使用寿命。温度太高会影响设备散热,温度太低又有可能造成设备长时间预热,影响使用。
These are the reasons for the uneven ink color of printed products. In addition, most of the prepress equipment is composed of advanced electrical components and integrated circuits, which are particularly sensitive to temperature and humidity. Too high and too low temperature and humidity will affect the service life of the equipment. Too high a temperature will affect the heat dissipation of the equipment, and too low a temperature may cause the equipment to be preheated for a long time and affect the use.
