一、印前预备
I. Pre-press preparation
预备作业包含:纸张的调湿处理、油墨的调制、潮湿液的制造、印版的查看、印刷压力的调试等。纸张调湿处理主要是防止环境气候形成纸张的含水量不均匀而引起纸张变形以及产生静电现象,这种现象在印刷中是肯定制止呈现的。
Preparatory work includes: paper humidity control, ink adjustment, wet liquid manufacturing, printing plate inspection, printing pressure debugging and so on. Paper humidification treatment is mainly to prevent the uneven moisture content of paper caused by environmental climate, paper deformation and electrostatic phenomenon, which is definitely prevented in printing.
二、装版试印
II. Binding and Trial Printing
印前预备作业做好之后,就可装纸、装版、开机调试。开机工作中,要对输纸机构、收纸机构、输墨设备、输水设备、印刷压力等方面对行调节,以确保走纸顺畅,供水量、给墨量适中,以印刷压力适合,印出高质量的印品。作业预备好后,将机器打开,使给墨量、供水量适中且均匀,之后在给纸台上加一些过版纸进行试印。套准作业完成后,开端试印,印出几张样品,进行质量查看。
After the pre-press preparatory work is done, paper loading, plate loading and startup debugging can be carried out. In order to ensure smooth running of paper, moderate water supply and ink supply, suitable printing pressure should be used to print high quality printing products. After the operation is ready, the machine is opened to make the ink supply and water supply moderate and uniform, and then some plate paper is added to the paper table for trial printing. After the alignment work is completed, the test printing is started and several samples are printed for quality inspection.
油墨调制作业包含专用油墨的制造、对常规油墨增加一些助剂等。如油墨黏度不适宜,应增加提高或下降黏度的调墨油;油墨干澡性欠好,可增加干澡剂。

Ink modulation operations include the manufacture of special inks and the addition of some additives to conventional inks. If the ink viscosity is not suitable, increase or decrease the viscosity of toner ink; ink dry bath is not good, can increase the dry bath agent.

印版的查看包含:印版类别、色别的查看,印版的厚度的检测,印版叨口大小的查看,规矩线的查看,印版深浅的查看,以及版面图文质量,有无污损、划伤等方面的查看。

The view of plate includes: the view of plate type and color, the detection of plate thickness, the view of plate tap size, the view of rule lines, the view of plate depth, and the view of layout quality, whether there are any stains, scratches and so on.

印刷压力的调试:依据印版厚度、纸张标准,橡皮布的厚度、包衬资料厚度、印刷工艺的要求等许多因素,挑选适宜的滚筒包衬,使得印刷压力契合印品工艺与质量要求。
Adjustment of printing pressure: According to plate thickness, paper standard, thickness of rubber cloth, thickness of lining materials, printing process requirements and many other factors, select the appropriate cylinder lining, so that printing pressure meets the printing process and quality requirements.
三、正式印刷
III. Formal Printing
正式印刷前,再加一些过版纸,过版纸印完后使计数器归零。印刷中要经常进行抽样查看,注意水上水的改变、油墨的改变、印版耐印力、橡皮布的清洁情况,以及印刷机供油、供气状况和工作是否正常等。
Before the official printing, add some offset paper, after the offset paper is printed, the counter will return to zero. Sampling inspection should be carried out regularly in printing. Attention should be paid to the changes of water, ink, printing plate endurance, rubber cloth cleaning, as well as the oil supply, gas supply and working condition of the printing press.
四、印后处理
IV. Post-printing
每天印刷完毕后,或每一批印件完成时,都要进行印刷后的处理操作,其内容包含:墨斗、墨辊、水辊、橡皮布、压印滚筒的清洁,印版、印张的处理和印刷机的保养等。
Every day after printing, or when each batch of printing is completed, the post-printing processing operation should be carried out, which includes: ink bucket, ink roll, water roll, rubber cloth, printing cylinder cleaning, plate, sheet processing and printing machine maintenance, etc.
