對制作PS版的鋁板基較基本的技術要求是表面光滑平整，無擦劃傷、坑包、印痕、非金履壓入、氣孔、軋制條紋等表觀缺陷，厚薄一致，波浪度控制在1mm內，平直度小于2I；組織細密均勻，無偏析、夾渣，內應力分由對稱、均勻；粗糙度Ra值小于0.28，以保證電解砂目細密均勻。目前我國大量使用的板基材料為1050A、1060等。
The basic technical requirement for making PS plate is smooth and flat surface, no scratches, pits, imprints, non-gold crawler indentation, porosity, rolling stripes and other apparent defects, uniform thickness, waviness within 1 mm, flatness less than 2 I; fine and uniform microstructure, no segregation, slag inclusion, internal stress from symmetrical and uniform The roughness Ra value is less than 0.28, so as to ensure that the electrolytic sand mesh is fine and uniform. At present, 1050A, 1060 and so on are widely used in China.
B堿洗
B alkali washing
通常，由鋁加工廠提供的鋁板，其表面都帶有一定量的油，油和氧化膜對砂目處理有影響，在PS版生產中常用熱堿沖洗鋁板進行表面處理。
Usually, the surface of aluminium sheet provided by aluminum processing plant contains a certain amount of oil. Oil and oxide film have an impact on sand treatment. In PS plate production, hot-alkali washing aluminium sheet is often used for surface treatment.
通常用堿液來去除氧化膜和油。常用除油液的配比為：NaOH的質量鈉等緩蝕劑及葡萄糖酸鈉、脂肪酸聚氧乙烯醚類增溶、絡合等表面活性劑。
Usually alkali solution is used to remove oxide film and oil. The common proportion of degreasing solution is NaOH mass sodium and other corrosion inhibitors, sodium gluconate, fatty acid polyoxyethylene ether solubilization, complexation and other surfactants.
除油液的溫度通?？刂圃?5～60℃左右，除油的效果與溶液的溫度有關。若溫度太高，則造民對鋁板基嚴重腐蝕，因而必須控制溫度。

The temperature of the degreasing fluid is usually controlled at about 55~60 degrees. The effect of oil removal is related to the temperature of the solution. If the temperature is too high, the generator will seriously corrode the aluminum plate foundation, so the temperature must be controlled.
除油的時間必須經過認真對比較后確定。因為，它與各種不同生產線有關。卷筒生產線則與生產線的速度有關，以4m/min為例，除油時間必須這到20s，其效果才能給以保證。
The time of oil removal must be carefully contrasted and finalized. Because it is related to various production lines. The drum production line is related to the speed of the production line. Take 4m/min as an example, the oil removal time must reach 20s, and the effect can be guaranteed.
除油液必須注意及時更新，因為在除油過程中會生成大量的皂化物、乳化物和鋁鹽，它們的存在影響除油效果，并阻礙對鋁板表面油污的皂化和乳化，當發(fā)現除油效果不強時，必須及時更新。通常若通過堿泵進行循環(huán)時，除油液能保持較長時間，若不循環(huán)則更新時間縮短。
Oil removal liquid must be updated in time, because a large number of saponifiers, emulsifiers and aluminum salts will be generated in the process of oil removal. Their existence affects the effect of oil removal, and hinders the saponification and emulsification of oil stains on the surface of aluminum plate. When it is found that the effect of oil removal is not strong, it must be updated in time. Usually, when circulating through the alkali pump, the oil removal liquid can be maintained for a long time, if not, the renewal time will be shortened.
檢查除油效果較簡單的辦法是用水。除油效果好的鋁板表面水能均勻地附著分散，若水倒上后，在鋁板表面呈水珠狀，則說明除油效果不好。除油的溫度要經常注意，除油液的溫度過低，則可能造成除油不徹底。
The easiest way to check the degreasing effect is to use water. The water on the surface of aluminum plate with good degreasing effect can be uniformly adhered and dispersed. If the water is poured on the surface of aluminum plate, the degreasing effect is not good. The temperature of the oil should be paid attention to frequently. Besides the low temperature of the oil, it may cause oil removal.
C酸洗
C pickling
在生產工藝中，堿洗之后有一硝酸酸洗過程，其目的是去除堿洗后的殘留物質，中和殘余的堿液。硝酸溶液的質量濃度為5％～10％。配制時注意將硝酸小心地倒入水中，充分混合。在酸洗過程中應經常注意溶液的濃度分析，及時補充。
In the production process, there is a nitric acid pickling process after alkali washing. The purpose is to remove the residual substances after alkali washing and neutralize the residual lye. The mass concentration of nitric acid is 5% to 10%. When preparing, carefully pour nitric acid into the water and mix it well. In the pickling process, we should pay attention to the concentration analysis of the solution and replenish it in time.
D粗化
D coarsening
粗化是為了形成具有要求粗糙度的砂目結構。粗化既可提高鋁板基表面對水的親和力，提高板基表面濕潤量，防止版面上臟；同時粗化后的表面還可提高版同與感光劑的附著力，進而提高印版的耐印力。
The coarsening is to form the sand mesh structure with required roughness. Coarsening can not only improve the affinity of water on the surface of aluminum plate, improve the wettability of the surface of aluminum plate and prevent the plate from dirty, but also improve the adhesion of the plate with the photosensitizer, thereby improving the printing endurance of the plate.
粗化后的砂目是由無數的凸峰和凹谷組成，不同的砂目結構，對保水性感光層的附著力影響較大，并對PS版的使用帶來較大影響。生產中用表面粗糙度測試儀繪制的砂目粗糙斷面輪廓曲線的特征參數來表征。
Coarsened sand mesh is composed of numerous peaks and valleys. Different sand mesh structures have great influence on the adhesion of water-holding photosensitive layer and the use of PS plate. Characteristic parameters of rough section contour curve of sand mesh drawn by surface roughness tester are used to characterize the curve.
