At present, in the printing industry, the method to identify the size of the page moisture is generally visual inspection, which is used to determine whether the page moisture is appropriate by visually observing the brightness of the printing plate and the surface of the ink roller and whether the ink color of the printed matter has faded. In addition, Jinan Printing Factory reminds you that the size of page moisture can also be identified from the following aspects in daily production:

1．墨輥表面滯留較多的水量會(huì)有光亮的視覺感，且串墨輥與傳墨輥之間會(huì)有水珠積聚現(xiàn)象；

1. A large amount of water on the surface of the ink roller will have a bright visual sense, and there will be water droplets accumulation between the string ink roller and the ink roller;

2．墨輥上的油墨產(chǎn)生超飽和乳化量時(shí)，用墨刀鏟墨會(huì)有水分滲出。當(dāng)往墨輥上加墨時(shí)，由于墨輥表面有水膜的存在，不易使油墨攪拌均勻，且輸墨輥下擺時(shí)容易出現(xiàn)打滑現(xiàn)象；

2. When the ink on the ink roller generates supersaturated emulsion, water will seep out when the ink is shoveled with the ink knife. When adding ink to the ink roller, due to the existence of water film on the surface of the ink roller, it is not easy to make the ink stir evenly, and the ink roller is prone to slip when swinging down;

3．墨斗中有細(xì)小的水珠滲出，且墨斗中可見到水珠時(shí)，說明水分過大;

3. If there are small water droplets seeping from the ink fountain and water droplets can be seen in the ink fountain, it indicates that the water is too large;

4．印刷過程中停車前后，由于墨輥與印版之間暫時(shí)處于分離狀態(tài)，水膜對(duì)油墨傳遞的阻隔作用變化，過多的水分會(huì)使印品墨色明顯變化；

4. Before and after the printing process stops, due to the temporary separation between the ink roller and the printing plate, the blocking effect of the water film on the ink transmission changes, and too much water will make the ink color of the printed matter change significantly;

5．經(jīng)過壓印后的紙張，若吸收了過多的水量，則顯得軟綿無力，輸送過程中就缺乏清脆的響聲；

5. If the embossed paper absorbs too much water, it will appear soft and weak, and there will be no clear sound during the transportation process;

6．水分過多時(shí)會(huì)阻礙油墨的正常涂布，使油墨積聚在墨輥上，這樣，盡管墨輥上墨層很厚，但印品墨色仍顯得發(fā)淡；

6. Too much water will hinder the normal coating of the ink and make the ink accumulate on the ink roller. In this way, although the ink layer on the ink roller is very thick, the ink color of the printed matter still appears weak;

7．水分過大時(shí)，停機(jī)時(shí)間較長(zhǎng)，版面水分仍不易蒸發(fā)散失；

7. If the moisture is too large, the downtime is long, and the moisture in the page is still not easy to evaporate and lose;

8．版面水分過多時(shí)，印張咬口部位印跡及空白面積大的邊緣印跡，容易呈現(xiàn)波浪型空虛現(xiàn)象；

8. When there is too much moisture in the layout, the impression at the nip of the sheet and the edge impression with large blank area are easy to show wavy emptiness;

9．水分過大時(shí)，橡皮布拖捎部位有水分滯留，過量的水分會(huì)在該處形成水珠。此外，橡皮滾筒、印版滾筒內(nèi)的襯墊物也容易被水分沾濕；

9. When the moisture is too large, there is moisture retention at the rubber blanket dragging part, and excessive water will form water drops there. In addition, the padding in the rubber cylinder and the printing plate cylinder is also easy to be wetted by water;

10．印張若吸收過量的水分，水大時(shí)剝離后出現(xiàn)變形，引起向下曲卷，造成收紙臺(tái)收紙紊亂，以及印張四邊也容易出現(xiàn)卷曲現(xiàn)象導(dǎo)致收紙不齊；

10. If the printed sheet absorbs excessive water, it will deform after peeling when the water is large, causing downward curling, which will lead to disordered paper receiving at the paper receiving table, and the four sides of the printed sheet are also prone to curling, which will lead to uneven paper receiving;

11．水分過大時(shí)，印品網(wǎng)點(diǎn)空虛，叼口部位印跡呈波浪型發(fā)淡，墨色暗淡缺乏光澤感。

11. When the moisture is too large, the print dot is empty, the print on the mouth is wavy and light, and the ink color is dim and lacks luster.
