防伪印刷是印刷工业中的一个领域，它涉及的项目包括纸币、护照、防揭标签、证券、邮票和身份证。防伪印刷的主要目的是防止伪造文书、涂改以及假币制造。

有许多技术被应用于防伪印刷工业

大多数纸币都使用加厚纸张来制作，几乎总是使用棉纤维来增强其强度和耐久性，在某些情况下，也会加入亚麻或者特种彩色纤维来增加纸张的特性，防止伪造。诸如罗马尼亚、墨西哥、新西兰、以色列、新加坡和澳大利亚等国还使用塑料来制作钞票来提高抗磨损能力，并且在钞票上面增加了一个可透光的窗口作为防伪措施，而这是一般的伪造设备所难以复制的。

Security printing is the field of the printing industry that deals with the printing of items such as banknotes, cheques, passports, tamper-evident labels, product authentication, stock certificates, postage stamps and identity cards. The main goal of security printing is to prevent forgery, tampering, or counterfeiting. More recently many of the techniques used to protect these high-value documents have become more available to commercial printers whether they are using the more traditional offset and flexographic presses or the newer digital platforms. Businesses are protecting their lesser-value documents such as transcripts, coupons and prescription pads by incorporating some of the features listed below to ensure that they cannot be forged or that alteration of the data cannot occur undetected.
