一、開印前,要憑經歷做好預調工作:
1. Pre-printing work should be done according to experience:
首先,依據打樣稿或印幅員文面積,粗略調理各色組墨斗的下墨量。在配有墨色遙控系統的機器上,這項工作更易完成。對此應有八成以上的預算,不要在印刷時邊印邊大范圍地調整墨量,以免形成很大的色差。
Firstly, according to the area of proofing manuscript or printing sheet, roughly adjust the ink quantity of each color group ink bucket. On machines equipped with ink remote control system, this work is easier to accomplish. There should be more than 80% of the budget for this. Do not adjust the amount of ink on a large scale when printing, so as to avoid a large color difference.
其次,依照消費工藝單的請求和該產品的特性,預先調理好飛達、收紙、油墨性能、壓力大小等各個環節,防止在正式印刷時手忙腳亂。其中,確保飛達牢靠、連續、穩定地輸紙是最重要的。有經歷的操作人員都是先依據紙張的幅面、厚度,預先調整好吹氣、吸氣、壓腳、壓簧、壓紙輪、側規、前規等,理順各部件之間的運動配合關系,確保飛達流利地輸紙,防止因飛達打頓而形成墨色深淺不一。這里倡議,有經歷的工人師傅能夠對飛達停止預先調整。
Secondly, according to the requirements of the consumption process sheet and the characteristics of the product, we should pre-regulate Feida, paper collection, ink performance, pressure and other links to prevent confusion in formal printing. Among them, it is most important to ensure that Feida feeds paper firmly, continuously and steadily. Experienced operators are based on the size and thickness of the paper, pre-adjusted air blowing, inspiration, foot pressing, spring pressing, paper wheel, side gauge, front gauge, etc., to straighten out the relationship between the movement of various components, to ensure that Feida fluent paper delivery, to prevent the formation of ink shades due to Feida Datong. It is advocated here that experienced workers can stop pre-adjusting Feida.
此外,還要針對該印品的用紙質量好壞、圖文面積大小,事前對油墨的黏度、活動性、枯燥性等恰當調理,以進步其印刷適性,確保印刷正常停止,不能因經常停機清洗橡皮布和印版上的紙毛、墨皮而形成墨色深淺不一。假如到了印刷中途再參加各種撤黏劑、調墨油,呈現顏色偏向是肯定的。
In addition, according to the quality of the paper used, the size of the graphic area, the viscosity, activity and dullness of the ink in advance, proper conditioning should be made to improve the printing suitability and ensure the normal stop of printing. The ink shade can not be different because of frequent shutdown to clean the paper fur and ink on the rubber cloth and the printing plate. If you go to the middle of the printing process to participate in a variety of viscose remover, toner, color bias is affirmative.
總之,將開機前的預調工作做好,就能夠大大降低正式開印后的毛病,機長也才有時間和精神集中看好墨色。

In a word, if we do well the pre-adjustment work before starting, we can greatly reduce the defects after the official printing, and the captain has the time and spirit to concentrate on the ink color.

二、正確調理水、墨輥壓力
2. Correctly adjusting the pressure of water and ink rollers
在印刷過程中,印幅員文局部必需得到時斷時續、平均適量的油墨,才干取得墨色分歧的印品。因而,墨輥與墨輥之間、墨輥與印版之間,必需堅持恰當的接觸和滾動關系,以完成油墨的良好傳送。假如這項工作做得不細致,不正確,墨色就不會堅持分歧。因而,每次裝置水、墨輥時,都堅持采用軋墨杠的辦法來逐一調理它們之間的壓力,而不用塞尺試拉力的傳統辦法,由于后者因各種人為要素招致的實踐誤差較大,在多色、高速機上更要禁用。至于軋墨杠的寬度,普通以4~5mm為宜。先調理傳墨輥與串墨輥之間的壓力,再調理著墨輥與串墨輥、印版滾筒之間的壓力,最后再調理傳水輥、靠版水輥、串水輥、中間輥互相之間的壓力,還有靠版水輥與印版滾筒之間的壓力,這幾個水路之間的墨杠以6mm為宜。
In the process of printing, it is necessary for the part of the printer to get intermittent and average amount of ink in order to obtain the printing with different ink colours. Therefore, the proper contact and rolling relationship between ink rollers and ink rollers and between ink rollers and printing plates must be adhered to in order to complete the good transmission of ink. If this work is not done carefully and correctly, ink will not insist on differences. Therefore, when installing water and ink rollers, we always stick to the method of rolling ink bars to regulate the pressure between them one by one, instead of the traditional method of pulling force test by plug ruler. Because the latter has large practical errors caused by various human factors, it should be banned on multi-color and high-speed machines. As for the width of the ink bar, 4-5mm is usually the best. First adjust the pressure between the ink transfer roll and the ink string roll, then adjust the pressure between the ink roll and the ink string roll, the printing plate roll, and finally adjust the pressure between the water transfer roll, the ink plate roll, the water string roll and the intermediate roll, as well as the pressure between the plate plate plate water roll and the printing plate roll. The ink bar between these water routes should be 6 mm.
