紙張的平滑度是非常重要的印刷適宜性，它是影響油墨轉移、圖文清晰的重要因素。平滑度高的紙張，在油墨厚度稍有變化時，仍能保持較高、較穩定的油墨轉移率，并能迅速在紙張上形成均勻光滑的油墨膜，具有良好的光澤度，色彩層次豐富、明亮、亮麗;另一方面,平滑度低,由于粗糙表面,毛孔,墨水滲透更重要的是,墨膜光澤度差,小分枝落入凹和印刷,紙張印刷質量標準不清楚,嚴重的會導致印刷,印刷顏色偏差等,直接影響到印刷印刷效果,特別是對于更高的香煙標簽印刷要求,應選擇高平滑度的紙印刷生產。
The smoothness of paper is a very important printing suitability, which is an important factor to affect the overall ink transfer and clear graphics and text. The paper with high smoothness can maintain a relatively high and stable ink transfer rate when the ink thickness slightly changes, and can quickly form a uniform and smooth ink film on the paper, with good glossiness, rich color layers, bright and bright; on the other hand, the smoothness is low, because of rough surface, pores, ink penetration, more importantly, the glossiness of the ink film is poor, Small branches fall into concave and printing, the quality standard of paper printing is not clear, which will lead to printing, printing color deviation and so on, directly affect the printing effect, especially for the higher requirements of cigarette label printing, the paper printing production with high smoothness should be selected.
造成雙重陰影的原因有很多，但更直接的原因是字跡精細的表面筆畫不光滑或不均勻，或者是印刷壓力造成的。為了達到印版轉印不暢等因素，才有可能給印版帶來效果，技藝設備對人員、印版、紙板、油墨、輔料配合得當。
There are many reasons for double shadow, but the most direct reason is that the fine surface strokes are not smooth or even, or the printing pressure. In order to achieve the factors such as plate transfer is not smooth, it is possible to bring effect to the plate. The technical equipment is suitable for personnel, plate, cardboard, ink and auxiliary materials.
這里的壓力分為上壓和下壓，上壓是指網紋輥與印刷輪之間的間隙。低壓是指印刷輪與印刷輪之間的間隙。壓力大間隙小，壓力小間隙大。超壓和超壓的效果是不同的。出現雙將仔細觀察印刷效果,如果雙出現在筆跡中風,是由于太多的壓力,適當的減少壓力,即網紋輥和印刷輪間隙擴大一些適當的,將受到飼料的方向,如果雙出現低于飼料方向,是由于太多的新聞。減少下壓力，即增加印刷輪間間隙，效果會得到改善。
Here the pressure is divided into up pressure and down pressure, up pressure refers to the gap between anilox roll and printing wheel. Low pressure refers to the gap between printing wheel and printing wheel. Large pressure clearance is small, small pressure clearance is large. The effect of overpressure is different from that of overpressure. The appearance of double will carefully observe the printing effect. If double appears in the stroke of handwriting, it is due to too much pressure, and the pressure is properly reduced, that is, the gap between anilox roll and printing wheel is enlarged by some appropriate ones, which will be affected by the direction of feed. If double appears lower than the direction of feed, it is due to too much news. Reducing down pressure, that is, increasing the gap between printing wheels, the effect will be improved.
