济南印刷厂纸张的平滑度重要吗?

来源:http://www.jnurs.com   日期:2020-09-17

  纸张的平滑度是非常重要的印刷适宜性,它是影响油墨转移全面、图文清晰的重要因素。平滑度高的纸张,在油墨厚度稍有变化时,仍能保持较高、较稳定的油墨转移率,并能迅速在纸张上形成均匀光滑的油墨膜,具有良好的光泽度,色彩层次丰富、明亮、亮丽;另一方面,平滑度低,由于粗糙表面,毛孔,墨水渗透更重要的是,墨膜光泽度差,小分枝落入凹和印刷,纸张印刷质量标准不清楚,严重的会导致印刷,印刷颜色偏差等,直接影响到印刷印刷效果,特别是对于更高的香烟标签印刷要求,应选择高平滑度的纸印刷生产。

  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.
  造成双重阴影的原因有很多,但更直接的原因是字迹精细的表面笔画不光滑或不均匀,或者是印刷压力造成的。为了达到印版转印不畅等因素,才有可能给印版带来效果,技艺设备对人员、印版、纸板、油墨、辅料配合得当。
  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.
  这里的压力分为上压和下压,上压是指网纹辊与印刷轮之间的间隙。低压是指印刷轮与印刷轮之间的间隙。压力大间隙小,压力小间隙大。超压和超压的效果是不同的。出现双将仔细观察印刷效果,如果双出现在笔迹中风,是由于太多的压力,适当的减少压力,即网纹辊和印刷轮间隙扩大一些适当的,将受到饲料的方向,如果双出现低于饲料方向,是由于太多的新闻。减少下压力,即增加印刷轮间间隙,效果会得到改善。
  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.
