introduction：Print creases are distributed according to state，Can be divided into large fold、Small discount、Straight break and branch break and other types，Mainly caused by machinery and paper itself，Especially when printing on thinner paper，More prone to creases。 1．The surface of the paper is uneven If the water content in the air is less than the water content of the paper，The water at the edge of the paper evaporates，Will appear”Tight selvedge”phenomenon(As shown at right)，The center of the paper will crease when printing；When the water content in the air is greater than the water content of the paper，The edge of the paper absorbs water，There is little water content in the middle of the paper，Marginal moisture content，Then appear“flounce”phenomenon，At this time printing is the paper drag tip
