油墨在传输的过程中，预置数据与实际生产所需数据之间会存在一定偏差，不能满足生产的需要，为解决数据的偏差问题，从墨量反馈技术方面出发，介绍了现阶段常用的墨量反馈技术原理及印刷机墨量预置后墨量偏差的修正方法。以系统性地了解该技术的原理及发展进程，并根据生产实践选用适宜的方法进行数据偏差修正。

In the ink transmission process, there is a certain deviation between the preset data and the required data, which can not meet the requirement of production. Principles of common used ink quantity feedback technologies and correction methods of ink quantity deviation after printer ink quantity presetting were introduced. The purpose was to provide reference in selection of suitable correction method according toe actual production practices.
