要实现这种标签印刷技术的突破，在不增加主要印刷设备进行重新投资的情况下，市场对新的标签印刷工艺高精度的要求，主要通过两种标签印刷途径
In order to achieve this breakthrough in label printing technology, we need to solve the market's demand for high accuracy of new label printing process without reinvesting the main printing equipment, mainly through two ways of label printing.
随着人们对产品标签的要求越来越多，标签印刷行业也发展的越来越成熟，标签行业正在迎来的发展机遇，同时传统的标签印刷行业也正在向更高层次发展，订单的交货周期要求越来越短的同时，标签印刷工艺的要求却越来越高。标签印刷工艺的要求提高主要体现在多种组合印刷方式的多项要求上。以单一的凸版印刷为主要印刷形式的年代已经一去不复返了。标签印刷制作工艺上要表现的效果除了凸版效果，更需要柔版效果、胶印效果、烫金效果、丝网印刷、凹版印刷效果，的红酒标签甚还需要压凹凸效果，冷烫工艺，局部UV过油等等。
With the increasing demand for product labels, the label printing industry is becoming more and more mature. The label industry is facing unprecedented opportunities for development. At the same time, the traditional label printing industry is also developing to a higher level. The order delivery cycle is becoming shorter and shorter. At the same time, the label printing process is required. But higher and higher. The improvement of label printing technology is mainly reflected in the requirements of various combinatorial printing methods. The era of single relief printing as the main form of printing has gone forever. In addition to the relief effect, the effect of flexographic effect, offset printing effect, bronzing effect, screen printing, gravure printing effect, and even the effect of indentation and convexity, cold pressing process, partial UV oil, etc. are needed for the production of high-grade red wine labels.
对于印刷精度方面要求的提高，主要体现在多种印刷工艺组合方式在实现的同时，还要有非常高的套印精度。但是往往由于现有设备的条件所限制，不能实现这一要求。我们无法回避目前国内标签印刷仍然是以凸版，或者单一柔版、树脂版印刷为主的实际现状，要增加多种标签印刷方式才可以。
For the improvement of printing accuracy, it is mainly embodied in the realization of various printing process combinations, but also has a very high overprint accuracy. However, due to the limitations of existing equipment, this requirement can not be achieved. We can not avoid the fact that the current domestic label printing is still based on relief printing, or single flexographic printing, resin printing as the main current situation, we need to add a variety of label printing methods.
要实现这种标签印刷技术的突破，在不增加主要印刷设备进行重新投资的情况下，市场对新的标签印刷工艺高精度的要求，主要通过两种标签印刷途径：
In order to achieve this breakthrough in label printing technology, we need to solve the market's demand for high accuracy of new label printing process without increasing the reinvestment of major printing equipment. We mainly solve the problem through two ways of label printing:
1.在现有的设备上增加补充功能，比如增加拉杆，过纸方面增加一些，并且不能影响印刷精度。
1. Adding supplementary functions to existing equipment, such as adding pull rods and paper passing, can not affect the printing accuracy.
2.离线实现所有的新的印刷工艺补充。
2. Off-line realization of all new printing process supplement.
国内目前主要是以凸版、树脂版或者单一柔版为主的标签印刷方式。一般而言，对于精密标签印刷，这两种方式基本上都是能够满足，但需要的特殊印刷效果，例如：立体感效果、强烈的金属感效果、柔软的浮雕效果、局部UV印刷等，却是无法满足的。这就需要在设备能够延伸或者有足够的工位的情况下，考虑加装补充工艺。
At present, the main label printing methods in China are relief printing, resin printing or single flexographic printing. Generally speaking, for precision label printing, these two methods are basically able to meet the needs of special printing effects, such as: stereo effect, strong metal effect, soft relief effect, local UV printing, etc., but can not be satisfied. This requires that additional processes be considered when the equipment can be extended or there are enough workstations.
在所有的加装工艺中，凹版印刷方式的加装是困难的，因为凹版所需要的印刷压力与张力都是非常大的。这样一来，在整体的控制中，如果控制不当，非常容易对原有的印刷方式及张力产生影响，从而影响套印，影响终的印品。所示的凹版印刷单元，通过独立的全伺服系统，提供二次套印的控制指令，并通过系统中浮动辊执行补偿实现精准套印。无论材料或者原有的印刷设备如何调整，升速降速控制，无论原有设备是主轴驱动还是伺服驱动，这套凹版系统都可以实现与原有系统的无速差同步状态，完全不改变原有的张力，因此可以完全跟踪原有的套印，从而实现工艺补充与升级。
In all the installation processes, gravure printing is difficult to install, because the printing pressure and tension required for gravure are very large. In this way, in the overall control, if not properly controlled, it is very easy to have an impact on the original printing methods and tension, thus affecting the overprint, affecting the final print. The gravure printing unit shown in this paper provides control instructions for secondary overprinting through an independent full servo system, and realizes accurate overprinting by compensating the floating roll in the system. No matter how to adjust the material or the original printing equipment, speed-up and speed-down control, whether the original equipment is spindle drive or servo drive, this gravure system can achieve synchronization with the original system without speed difference, without changing the original tension, so it can track the original overprint completely, thus realizing the process. Supplement and upgrading.
