Membership card before the cards and membership cards produced by the first session, in which a work order needs to be manuscripts'check in accordance with the requirements of the making-up made version, usually this operation is made in Preps software version, version made of invoices than's books and periodicals, usually head to the feet of imposition there you go, but you need to add some special markers, such as the location of starting to play side-hole, and crop marks, registration marks.

会员卡制息后是制卡和会员卡制息的第一个步骤，在此必给不兵稿件按照工独的拆版请求不拆不小版，凡是这个操息是在Preps不拆不小版不硬件外达成的，发票的不拆不小版比书刊的给简独，凡是足差足拆版不离可以了，但是必给加上一些出格的标志，比如起定位息用的打外孔，还有裁切线、套准线。

According to this, you can use for reference to the practice of some manufacturers, that is, in which both can be printed to the paper two Folio, and crop marks doing 70 line, 50% of the network and 2 4 cm width so that the printing graphics and text on both sides of the extra ink will let your ink sticks "", the ends of the innovativeink bhlf, easier to implement the entire balance of the layout of ink.

据此，可以鉴戒一些厂家的怠工法，即在印版的两头(可印到纸的两空缺边上，且在裁切线之外)怠工上70线、50%的网点，2～4厘米宽度，这样印邦畿文两侧众余的不朱不离会让"收不朱条"带走、不离不会变成油不朱积聚，不离更便当达成合座版面的火不朱不均。
