The requirements provide criteria to guarantee the image quality of print scanners and printers that input print images or generate print images. According to the International Standard Organization, the minimal requirements that a print scanner must meet are: image resolution, size, gray level color range, sample rate, light intensity and signal to noise ratio. The images must be true representations of the input prints, without creating any significant artifacts, anomalies, false detail, or cosmetic image restoration effects. The print scanner must produce images that exhibit good geometric fidelity, sharpness, detail rendition, gray-level uniformity and gray-scale dynamic range, with low noise characteristics.

The biometric technologies designers have the need to work with biometric standards that define the characteristics and minimum requirements to develop devices and appropriate models for the biometric data management for public and private entities, law enforcement and government areas. Biometric sensors are devices that are located within a biometric system, which have the function of acquire data or images for biometric feature extraction. Biometric systems are used to provide greater security for systems that are used as mechanisms for identifying and verifying people. INTRODUCTION A biometric system is an automated system to capture biometric sensor data from a user, extract feature data from that processed acquired data, compare the processed feature data with that contained in one or more biometric templates, decide how well they match and indicate whether or not an identification or verification of identity has been achieved. Keywords - print scanners Biometric Standards physical characteristics. As a result of this devices classification, 73% of them with at least one biometric standard or and 27% of them do not specify if they meet some kind of standard however, they have the requirements to be considered for the acquisition of a print image. A print device classification was performed based on the number of prints that each device can capture, for example devices or a single print capture and type of biometric standard compliant. Because there is a huge print scanners variety, this paper studies only 3 devices from 13 different vendors using the characteristics obtained from the specification sheets for each device. This paper discuses an analysis of the characteristics of print biometric scanners based on biometric standards compliance, taking into account of the features provided by manufacturers to conduct a comparative analysis of their physical characteristics, its s and standards supported. 1 Fingerprint Scanners Comparative Analysis Based on International Biometric Standards Compliance María del Carmen Prudente-Tixteco Linda Karina Toscano-Medina Gualberto Aguilar-Torres Gabriel Sánchez-Pérez Abstract.
