济南彩色设计印刷公司一直钻研于如何提高印刷品质量的问题上,经过不断的摸索,终于得到了一些结论,下面我们把这些方法分享给大家,希望对大家有所帮助。
Jinan color design and printing company has been studying how to improve the quality of printing, after constant exploration, finally got some conclusions, we will share these methods to everyone, I hope to help you.
首先,掌握和控制水墨平衡,是稳定提高印刷质量的关键。水墨平衡是印刷的基础,只有水墨控制恰到好处,才能使印出的报纸图文清晰、墨色深浅一致,套印才能准确。掌握好水墨平衡关键在于水。在保证不上脏的前提下,把水控制在更小范围内,并使水量和油墨量处在比较稳定的状态。水太少,不仅上脏,而且版面字迹无光泽,浅淡发灰,印迹不实,有时还会出现雪花点:水太大,又会出现印迹不饱满,图文变淡,字迹发虚,无层次等。水墨的绝对平衡是没有的,只有相对平衡。为了稳定墨色均衡,北京印刷厂就要求在实际工作中,做到以下几点:
First of all, mastering and controlling the balance of ink and wash is the key to stabilizing and improving printing quality. The balance of ink and water is the basis of printing. Only when the ink and water control is proper, can the printed newspapers have clear pictures and texts, the ink color is consistent, and the overprint can be accurate. The key to mastering the balance of water and ink is water. On the premise of not being dirty, the water should be controlled within the minimum range, and the amount of water and ink should be in a stable state. Too little water, not only dirty, but also glossy, light gray, imprinted, and sometimes there will be snowflakes: water is too big, and will appear imprint is not full, the picture and text will become light, the writing is empty, no hierarchy, etc. The absolute balance of ink and wash is not, only relative balance. In order to stabilize the ink balance, Beijing printing factory requires the following points in practical work:
控制车间的环境和温湿度,有利于提高印刷质量。由于版面水分是以直接和间接的形式散发的,版面水分在满足印刷时水墨平衡需要时,大部分是向空间散发的。一般情况下,环境温度越高散发的越快。
Controlling the environment and temperature and humidity of the workshop is conducive to improving the printing quality. Because the moisture of the page is diffused directly and indirectly, the moisture of the page is mostly diffused to the space when it meets the needs of ink balance in printing. In general, the higher the ambient temperature is, the faster the emission.

购进辅助材料时,因尽量满足水墨平衡的需求。油墨、版材、气垫橡皮布、纸张等方面与墨色大有关系。纸张用量比重大,其质量差是考虑其经济方面,但版材、油墨等主面还要把住选材关,应尽量选用好的材料,一般情况下不要经常更换品牌。让车间使用有规律,原则上是应该用什么买什么,而不应该是买什么用什么。

When purchasing auxiliary materials, try to meet the needs of ink balance. Ink, plate, air cushion rubber, paper and so on are related to ink color. Paper consumption ratio is significant, its poor quality is to consider its economic aspects, but the plate, ink and other main aspects of material selection should also be checked, should try to choose good materials, in general, do not often replace the brand. Let the workshop use regularly, in principle, what should be used to buy what, not what should be used to buy what.
加强印刷设备的维护和检查,是提高印刷质量的手段。印刷设备的先进与否,维护与保养是否跟上,对提高印刷质量至关重要。因此在实际工作中,要想提高印品的质量,就必须加强对印刷设备的维护和保养。经常清洗墨辊、墨槽、水箱、水辊和水槽。印刷厂这种清洗包括每天印刷结束后的清洗,每次换色前的清洗和定期的彻底清洗,不让油墨残留在橡皮布表面的毛孔内。否则日久氧化结膜,降低油墨的吸附能力,使油墨转移降低。经常清除墨槽内的残墨,以及墨键周围的杂质,使墨键收放自如。特别是现在的遥控校墨装置,更应该保证其墨键周围的清洁。要经常清洗水箱、水槽和水辊,保证水路的循环畅通,换水时注意润版水的配备比例,使水的pH值处在正常状态。
Strengthening the maintenance and inspection of printing equipment is a means to improve the quality of printing. Whether printing equipment is advanced or not, whether maintenance and maintenance are kept up is very important for improving printing quality. Therefore, in practical work, in order to improve the quality of printing, we must strengthen the maintenance and maintenance of printing equipment. Wash the ink roller, ink tank, water tank, water roller and sink regularly. This cleaning includes cleaning after the end of each day's printing, cleaning before each color change and regular thorough cleaning, so that ink does not remain in the surface of the rubber cloth pores. Otherwise, it will oxidize the conjunctiva for a long time, reduce the adsorption capacity of ink and reduce the ink transfer. Often remove the residual ink in the ink tank, and the impurities around the ink key, so that the ink keys can be retractable freely. In particular, the current remote control ink unit should ensure the cleanliness of the ink keys around it. The tank, sink and rollers should be cleaned frequently to ensure the smooth circulation of the water path, and the proportion of the plate water should be paid attention to when changing the water, so that the pH value of the water is in a normal state.
注意润版液的配备的比例。DSC润版液和润版液,配备的比例一般是2%~2.5%,控制其水温在16℃左右,pH值在5.5~6.5左右,电导值在1600左右,盐度在0.50左右。
Pay attention to the proportion of the fountain solution. The ratio of DSC plate wetting solution and plate wetting solution is generally 2%~2.5%. The water temperature is controlled at about 16 C, the pH value is about 5.5~6.5, the conductivity is about 1600, and the salinity is about 0.50.
根据纸的质量不同,及时调整水墨的供给量。由于纸张产地不同,纸张的光滑度也不同。季节不同,纸张的含水量大小也不同。所以在印不同的纸张时,应及时调整水墨平衡。一般光滑和纸屑较少的新闻纸水量稍小些,粗糙的和纸屑多的新闻纸,水量要稍大一些;机器高速运转时,由于速度快水量相对要小一些,低速运转时可稍大一些。这主要根据设备、纸张、油墨的一般性能和室内外的不同情况来调整水墨供给量。
According to the quality of paper, adjust the supply of ink in time. Because of the different origin of paper, the smoothness of paper is also different. The moisture content of paper varies from season to season. Therefore, when printing different paper, we should adjust the balance of ink and wash in time. Newsprint, which is generally smooth and has less scraps of paper, has a slightly smaller amount of water. Rough and more scraps of paper have a slightly larger amount of water. When the machine is running at high speed, the amount of water at high speed is relatively small, so it can be running at low speed. This is mainly based on equipment, paper, ink general performance and indoor and outdoor conditions to adjust the ink supply.
