纸箱印刷的常见问题
Common problems in carton printing
东莞纸箱厂制作过程中,经常能改遇到版面图文出现脏、糊版或局部图文印迹不清的质量问题,下面就来说说遇到这些问题需要怎么解决。
In the production process of Dongguan carton factory, we often encounter the quality problems of dirty layout, paste version or unclear local graphic imprint. Here's how to solve these problems.
1、颜色顺序不当造成的质量缺陷
1. Quality defects caused by improper color sequence
如果印刷版面是全文字排列在同一组,当瓦楞纸板在同一组印刷过程中,组印制板图文着墨不良,干燥缓慢,易被弄脏转移造成的版面由脏。
When the same group of words and texts are transferred slowly in the printing process, it is easy to dirty the same group of words and texts.
为了防止这种病的产生,有必要在组彩色印刷中安排小面积的布局,并将大面积的版面安排在下面的彩色组印刷中,以避免由于转印造成的脏印刷。
In order to prevent the occurrence of this disease, it is necessary to arrange the layout of small area in group color printing, and arrange the layout of large area in the following color group printing, so as to avoid dirty printing caused by transfer printing.
2、相关部件造成的机器印质量故障
2. Machine print quality failure caused by relevant components
当印版辊轴、压花辊轴、传动轴、齿轮和压花与重要部件的磨损、松动、跳动或滑动造成压印过程中辊或压花辊现象,由于压力不稳定,
When the plate roller shaft, embossing roller shaft, transmission shaft, gear, embossing and important parts are worn, loose, jumping or sliding, resulting in the phenomenon of roller or embossing roller in the embossing process, due to unstable pressure,
导致打印布局和板接触不正常、糊版或局部原因图文印迹不清晰的问题,纸板印刷表面。通过仔细细致的观察和分析,
Lead to abnormal contact between printing layout and board, paste plate or unclear graphic imprint for local reasons, and the printing surface of paperboard. Through careful observation and analysis,
找出故障的确切位置,采取相应的措施加以处理,对磨损和松动部位进行修补,故障现象。
Find out the exact location of the fault, take corresponding measures to deal with it, repair the worn and loose parts and eliminate the fault phenomenon.
3、压力辊调整不当引起的质量故障
3. Quality failure caused by improper adjustment of pressure roller
如果压力辊太高或太,以致与瓦楞纸板接触过紧或过松,也会出现脏版、糊版或局部图文印迹不清晰,压辊应调整到适当的位置,
If the pressure roller is too high or too low to make contact with the corrugated board too tight or too loose, there will also be dirty version, paste version or unclear local graphic imprint. The pressure roller shall be adjusted to the appropriate position,
使压辊与辊之间的间隙和板的合适厚度,确保印刷品生产零部件,避免故障现象。
Make the gap between the press roll and the roll and the appropriate thickness of the plate to ensure the production of printed parts and avoid failure.
4、印版厚薄不均造成的质量不合格。
4. Unqualified quality caused by uneven thickness of printing plate.
当橡胶板厚度不均匀时,板的布局会出现高。版面高的地方容易糊版,版面的地方容易出现的不足,造成印迹不清晰,为了避免不利的情况下,
When the thickness of the rubber plate is uneven, the layout of the plate will appear high and low. In order to avoid adverse situations, it is easy to paste the plate where the layout is high, and it is easy to have deficiencies where the layout is low, resulting in unclear marks,
散板,由多个小的板(为了节省橡胶板与板芯板技术),应该产生相同的块板,这样它的厚度差异比较小。
Loose plate, composed of multiple small plates (in order to save rubber plate and plate core technology), should produce the same block plate, so that its thickness difference is relatively small.
如果已经准备好橡胶板,存在厚度差,可以弥补局部在薄板背面胶层较多,使印版厚度基本保持一致,保证印刷压力和油墨均匀布局。
If the rubber plate has been prepared and there is a thickness difference, it can make up for the large number of adhesive layers on the back of the thin plate, so as to keep the thickness of the printing plate basically consistent and ensure the uniform layout of printing pressure and ink.
5、滚子质量不良造成的故障
5. Failure caused by poor roller quality
当辊轴松动、上墨辊弯曲、变形或表面损坏时,也可造成页面脏、粘贴版或局部图文不清晰。我们应找出原因,
When the roller shaft is loose, the inking roller is bent, deformed or the surface is damaged, it can also cause dirty pages, pasted plates or unclear local pictures and texts. We should find out why,
采取相应的措施加以处理,使滚筒与印版之间保持接触条件的统一和适当,更换损坏的滚筒,故障现象。
Take corresponding measures to deal with it, keep the contact conditions between the drum and the printing plate uniform and appropriate, and replace the damaged drum to avoid failure.
6、瓦楞纸板厚度不均引起的6大质量问题
6. Six quality problems caused by uneven thickness of corrugated board
如果空心痕迹形成的波纹表面有人为破坏,凹陷部分的纸张会出现质量缺陷,不清楚,如果采取了增加印刷压力补偿,
If the corrugated surface formed by the hollow trace is artificially damaged, the paper in the concave part will have quality defects, which is unclear. If the printing pressure is increased for compensation,
容易使文字线,页面质量的粘贴。为了避免糊的布局,瓦楞纸板在堆放、搬运过程中,应注意轻、轻、轻(要控制堆放高度),不得使用抛掷、粉碎、压力等不良生产习惯进行处理。
Easy to make text lines, page quality paste. In order to avoid the layout of paste, during the stacking and handling of corrugated board, pay attention to light, light and light (the stacking height shall be controlled), and do not use bad production habits such as throwing, crushing and pressure.
