Printing is only a test of plate-making quality. However, on the premise of stable plate quality, because the printers are not careful, they can not get the ideal printed matter, on the contrary, it will lead to greater waste and produce inferior or waste products.

在批量印刷前，應(yīng)先固定好印刷網(wǎng)版倒入油墨試印，檢查版面圖文復(fù)制的層次、墨色、墨層厚薄、規(guī)格、套準(zhǔn)精度等。若套準(zhǔn)精度較差，可以根據(jù)框架前面的微調(diào)旋鈕進行調(diào)整；若油墨的色相不對，檢查是否用錯油墨，并立即更換；若著墨不良，可用溶劑擦拭印版圖文部分，使油墨的透過性能及對承印物的潤濕性得到一定的改善；若圖文的階調(diào)和層次有較大差異，則應(yīng)立即更換印刷網(wǎng)版。在印刷過程中必須注意如下幾點。

Before batch printing, the printing screen should be fixed and put in the ink for trial printing, and the levels of layout, ink color, ink thickness, specifications, registration accuracy and so on should be checked. If the alignment accuracy is poor, adjustments can be made according to the fine-tuning knob in front of the frame; if the color of the ink is not correct, check whether the wrong ink is used and replace it immediately; if the ink is not good, the solvent can be used to wipe the printing plate and text parts, so that the ink permeability and the wettability of the substrate can be improved to a certain extent; if the ink color is not correct, check whether the wrong ink is used and replace it immediately. If there are great differences in the level of reconciliation, the printing screen should be replaced immediately. In the process of printing, the following points must be paid attention to.

（1）勤看規(guī)矩。由于版框在印刷時來回不停地運動，使印版與框架在往返運行中受到碰撞及震動，二者間發(fā)生小小的位移，就出現(xiàn)套印不準(zhǔn)確的現(xiàn)象，影響產(chǎn)品的外觀質(zhì)量。因此要勤看規(guī)矩，及時發(fā)現(xiàn)，及時調(diào)整。

(1) Watch the rules diligently. Because the plate frame keeps moving back and forth during printing, the plate and the frame are collided and vibrated in the round trip operation. A small displacement occurs between the plate and the frame, which results in imprecise overprinting and affects the appearance quality of the product. Therefore, we should be diligent in observing the rules, discovering them in time and adjusting them in time.

（2）常檢查樣張。發(fā)現(xiàn)印刷品印跡缺墨，應(yīng)立即用干凈的棉布擦拭網(wǎng)版。這種情況多數(shù)是由于印版上粘有碎塑料膜或油墨結(jié)皮干燥堵塞網(wǎng)版所致。若發(fā)現(xiàn)墨色不勻或變得淺淡，可能是油墨粘度過大，應(yīng)立即停機用溶劑稀釋油墨的粘度，同時用汽油擦拭版面的圖文部分，防止?jié)B墨或堵網(wǎng)，以便于連續(xù)工作。

(2) Examine samples frequently. If ink deficiency is found in printed matter, the screen plate should be wiped with clean cotton cloth immediately. This situation is mostly due to the sticking of crushed plastic film or ink crust on the printing plate to dry and clog the screen plate. If the ink color is uneven or light, it may be that the ink viscosity is too high. Solvent should be stopped immediately to dilute the ink viscosity. At the same time, gasoline should be used to wipe the graphic and textual parts of the layout to prevent ink penetration or blocking, so as to facilitate continuous work.

（3）半成品的堆放要整齊。在半成品的堆放過程中，一定要使紙的兩邊下垂疊放。否則紙張由于本身的重力作用而形成上弓形，紙的兩邊上翹而不平坦，印刷時造成紙張傳遞困難，常會出現(xiàn)斷張現(xiàn)象。紙垛不平時，可用硬紙板墊平，同時紙垛的高度要經(jīng)常用分紙機構(gòu)的調(diào)節(jié)旋鈕進行調(diào)整，以便紙張傳遞順暢，印刷過程順利進行。

(3) The stockpiling of semi-finished products should be neat. In the process of stacking semi-finished products, the two sides of paper must be sagged and stacked. Otherwise, due to the gravity of the paper itself, it will form an upward bow, and the two sides of the paper will be warped and uneven, which will make the paper difficult to transfer and often lead to tension breakage. When the stack is uneven, it can be padded with cardboard. At the same time, the height of the stack should be adjusted by the adjusting knob of the paper splitting mechanism so that the paper can be transferred smoothly and the printing process can be carried out smoothly.
