平压平型印刷机的结构特点是，装版机构和压印机构均呈平面形。印刷时，压印平版绕主轴进行往复摆动，完成输纸和压印。由于印版图文部分的油墨和压印平版同时全部接触，因而压印时间较长，对承印物所施加的压力较大，故印刷品的墨色浓重，线条、笔画饱满。
The structural feature of the flat press is that both the plate mounting mechanism and the stamping mechanism are in plane shape. During printing, the lithography plate swings back and forth around the main shaft to complete paper feeding and printing. Because the ink of the image and text part of the printing plate and the printing plate are all in contact at the same time, the printing time is long and the pressure on the substrate is large, so the ink color of the printing article is thick and the lines and strokes are full.
