全面剖析平版印刷的原理及特点
作者:admin 来源:http://www.sdhzyw.com 发布时间:2018-7-16 15:25:54 浏览次数:764
印刷厂的平版印刷是利用油水不相溶的自然现象,印版图文部分能亲油疏水、空白部分能亲水疏油的选择吸附性而达到的。
The lithography of the printing plant is a natural phenomenon that is insoluble in oil and water.
由于在印刷过程中印版表面既要接受油墨又要接纳润版水分,因此,使纸张吸到更小的水分,为了提高印刷厂的印刷速度和印版的耐印率,平版印刷采用了与凸版、凹版不同的滚压方法--间接印刷方法。
In order to improve the printing speed and the printing rate of the printing plate, in order to improve the printing speed of the printing plant and the printing rate of the printing plate, the offset printing method, which is different from the convex plate and the gravure plate, is used in the printing process.

为了使平版印刷能进行彩色复制,并且用更少的颜色再现出原稿千变万化的颜色,平版印刷又采用了网点成色的方法。

In order to make color copy of the lithography, and to reproduce the original manuscript with the variable color with the least color, the plate printing adopts the method of dot color.
因此人们把油水不相溶、印版选择吸附性、间接印刷和网点呈色作为平版印刷更基本的原理。
Therefore, the basic principle of lithography is that oil and water do not dissolve, printing plates choose adsorption, indirect printing and dot coloring.
在平版印刷中,由于橡皮布具有较高弹性,使弹性衬垫材料产生压缩形变,于是油墨在印版滚筒、橡皮滚筒、压印滚筒之间,可以在较小的印刷压力下进行转移。印刷厂使得印刷品具有色调柔和、层次丰富的特点,是复制彩色印刷品十分理想的印刷方法。
In lithography, due to the high elasticity of the rubber cloth, the elastic cushion material produces compression deformation, so the ink can be transferred between the plate roller, the rubber roller and the press drum, and can be transferred under the smaller press pressure. The printing press makes the printed products have the characteristics of tonal, soft and rich layers. It is an ideal printing method for copying color printed matter.
平版印刷的板材,通常采用铝板和锌版,这种印版轻而薄、制版成本低、操作也很方便。
Planographic printing plates usually use aluminum and zinc plates, which are light and thin, low cost and easy to operate.
平版印刷机是圆压圆的轮转印刷机,又都附设先进的输墨、定位、套准等控制印刷质量的装置,有的还利用热风、红外线、高频红外等装置来加速油墨的干燥,这就使得印刷厂的印刷速度和印刷质量都有了显著的提高。
The lithography machine is a round press, and it is also equipped with advanced ink transmission, positioning, set and other devices to control the quality of printing. Some also use hot air, infrared, high frequency infrared and other devices to accelerate the drying of ink, which makes the printing speed and printing quality of the printing plant have been significantly improved.
和凸印、凹印相比,平版印刷还具有生产周期短、材料消耗少、印刷成本低的特点,不但幅面的色彩印刷品用于平版印刷,甚至以前只采用凸版印刷的书刊、报纸,也随着电子照排和激光照排版的普遍应用,逐渐采用平版印刷。
Compared with the bump and intaglio printing, the lithography has the characteristics of short production cycle, less material consumption and low printing cost. Not only the color printing products of the amplitude are used for the lithography, but even the books and newspapers, as well as the printed printed books and newspapers, have been used gradually with the universal application of the electronic and laser typesetting.
平版印刷是利用橡皮布来转移印版上的图文油墨的,印版的空白部分必须用润版液来润湿,在工作中我们不仅要掌握橡皮布的弹性压缩变形、尺寸稳定性等因素。另外,平版印刷主要是用来复制色彩印刷品,所以操作人员除了要掌握一般操作技术,而且要有一定的物理、化学、色彩、机电等方面的知识,才能印出较为理想的印刷品。总之和凹印、凸印的印刷工艺相比较,在平版印刷过程中,影响印刷品质量的因素较多,技术操作难度较高,所以对廊坊印刷厂从业人员的素质相应也有较高要求。
Lithography is the use of rubber cloth to transfer the printing ink on the plate, the blank part of the plate must be moistened with the moistening plate. In the work, we should not only grasp the elastic compression deformation, size stability and other factors. In addition, the lithography is mainly used to copy the color printing, so the operator, in addition to mastering the general operation technology, and has some knowledge of physics, chemistry, color, mechanical and electrical and so on, can print more ideal print. In a word, compared with the printing process of gravure and bump, in the process of lithography, there are many factors affecting the quality of printing products, and the difficulty of technical operation is high. Therefore, the quality of the employees in Langfang printing plant is also higher.
