摘要： A cleaning apparatus designed for use in conjunction with a lithographic printing member associated with a rotary cylinder comprises an elastomeric (preferably foam) roller for making rotating contact with the printing member; a fixed screen; and a brush in rotating contact with the roller and with the screen. The roller may extend axially at least across the imaging region of the printing member (i.e., that portion of the imaging member that actually receives the image to be printed). The elastomeric roller removes imaging debris from the cylinder, while the brush removes from the roller debris that would otherwise accumulate therein. As the brush rotates past the screen, it sheds debris withdrawn from the roller; debris passing through the screen may be collected, for example, in a container or removed from the system by vacuum. The system may also include one or more doctor blades in contact with the roller for removing debris remaining on the roller following its contact with the brush.

摘要： Printing plates are mounted onto a cylinder by first establishing a temperature difference between the plate and the cylinder; in particular, the temperature of the plate exceeds the temperature of the cylinder. The plate is then wrapped around the plate cylinder, and the temperature difference causes the plate to shrink against the cylinder.
摘要翻译：首先在印版和圆筒之间建立温度差，将印版安装在圆筒上; 特别地，板的温度超过气缸的温度。然后将板卷绕在印版滚筒上，并且温度差导致印版相对于圆柱体收缩。

摘要： A magnetic plate retention system especially suitable for use in retaining a lithographic plate material to a conventional plate cylinder utilizes one or more magnetic retention devices each having a curved surface complementary to the cylinder. When disposed on the plate, the retention devices magnetically adhere the plate to the underlying cylinder.
摘要翻译：特别适用于将平版印刷版材料保持在常规印版滚筒上的磁性板固定系统利用一个或多个磁性保持装置，每个磁性保持装置具有与圆柱体互补的曲面。当设置在板上时，保持装置将板粘附到下面的圆筒上。
