摘要： Predetermined print control signals are provided to a digital printing mechanism that responds to the print control signals to print an image on a substrate. A reference signal is derived from said print control signals. The image is scanned to generate a post-print signal. The reference signal is compared with said post-print signal. If the reference signal and the post-print signal do not compare within predetermined standards, an output signal indicative of poor print quality is generated. The print mechanism can be incorporated into a postage metering system and the image can be a postal indicia. The postage meter is responsive to a signal generated as a function of the output signal to inhibit further printing of postal indicia. Prior to printing the image, a substrate upon which the image is to be printed is scanned to generate a reflectance signal, the reflectance signal being used to correct the post-print signal. The post-print signal can represent integration of reflectance over segments of the image, or can represent summation of scanned pixels over segments of the image.

摘要翻译： 预定的打印控制信号被提供给数字打印机构，其响应于打印控制信号以在基板上打印图像。 从所述打印控制信号导出参考信号。 扫描图像以产生后打印信号。 将参考信号与所述后打印信号进行比较。 如果参考信号和后打印信号在预定标准内不进行比较，则产生指示打印质量差的输出信号。 打印机构可以并入邮资计费系统中，图像可以是邮戳。 邮资计对响应于作为输出信号的函数产生的信号以阻止邮戳的进一步打印。 在打印图像之前，扫描要打印图像的基板以产生反射信号，反射信号用于校正后打印信号。 后印刷信号可以表示图像的片段上的反射率的积分，或者可以表示图像的片段上的扫描像素的和。
