The modular design of printNet system is divided into several application part, such as data processing tools, design tools, products, Business card printing tools, and solutions to technical tools, of which the highest is a design tool over the actions that it printLayout from page formatting and setting variables, but also can be used by an operator in a transform tool programming, so that the contents of the variables in a database in output for operations, now produetion of mostly to one-dimensional bar codes and encrypted bit or anti-false, the party is a method in the bar code by addition, subtraction, multiplication, Division, opinins Mo, and so after the results or the results of data, or the result is converted to the data that corresponds to a location in one of the ntehs detection accuracy is valid, just make a bit of the inverse operation, the operation that results in comparison with the original data, such as the same as the data is valid, such as different then the data is not valid, this scenario is the most simple and most primitive anti-counterfeit. PrintNet software to complex product environment " interpuntion and output the integration of integrated management " solution possible.

printNet系统的模块式设计分为几个应用部分，如数据处理工具、设计工具、产品制卡工具以及方案解决工具，其中技术含量最高的是对设计工具printLayout的操作，它除了设计页面格式和设置变量外，还可由操作员在转换工具中编程，以便对数据库中的变量内容在输出时进行运算操作，现在生产中应用的大多是给一维条码加校验位或是防伪加密，其方一法是将条码中的数据经过加、减、乘、除、取莫等运算后，将结果或将结果中的几位至于数据后，或将结果转换成对应符号放在数据中的某个位置，如须检测某一数据是否准确有效，只要把校验位上的数进行逆运算，把运算结果与原数据比较，如相同则数据有效，如不同则数据无效，这种方案是最简单最原始的防伪加密的方法。printNet软件系统使得在复杂产品环境下的&排版与输出一体管理&的集成解决方案成为可能。
