Title:
【発明の名称】真空ドラム上に印刷プレートを保持する装置及び方法
Document Type and Number:
Japanese Patent JP3370962
Kind Code:
B2
Abstract:
A retainer for holding a printing plate to the cylindrical surface of a vacuum drum has a curved surface which conforms to and seals against the cylindrical surface of the drum. The retainer is held in place by pressure differential. An edge portion of a printing plate is received below a lip which extends along the retainer. The retainer is light in weight and therefore does not significantly unbalance the drum even if it is not always in the same position on the drum. The retainer is also inexpensive to manufacture and less likely than prior art clamps to cause damage if it fails.
