The current intaglio printing press mainly adopts a printing roller with a negative engraving pattern, and the printing roller is dipped with ink to print the pattern on a printing stock. After the intaglio printing press is used for a long time, the inventor finds that the current intaglio printing press mainly has the following defects:

1. the thickness requirement of the printing stock is fixed, and mainly the clearance between the conveying rollers at two sides of the printed matter is fixed, so when the printing stock faces different thicknesses, the printing is required to be carried out by different printing machines. On the one hand, the purchase, management and maintenance cost of the enterprise is increased, and the complex selection is brought to the operation of workers.

2. In order to avoid influence such as dust, granule on the stock to print the effect, need clear up the stock surface before the stock gets into the printing roller, the mode that adopts at present is sticky, just also adopts the glutinous rubber roller that has the stickness to roll on the stock surface to utilize the stickness on the stock to get rid of large granule impurity such as dust on the stock. However, this method is not suitable for some printing materials which are easy to remove hair and delaminate, and in addition, frequent overhaul and replacement of the glue roller are required, which causes the cost of later maintenance to rise greatly.

3. Need carry out timely stoving to the stock after the printing is accomplished, the cooling of drying the back needs of blowing, in order to avoid the granule in the air current to cause the influence to the printing face (because the printing ink is not always dry thoroughly after the stoving, in case solid particles such as dust fall on the printing face and will cause the printing face to be polluted this moment, seriously influence the printing effect), generally need carry out filtration treatment to the air current, mainly adopt air filter to filter at present.
