12、om IHS -,-,- ANSI/AIIM MS62-1999 RECOMMENDED PRACTICE FOR COM RECORDING SYSTEMS HAVING AN INTERNAL ELECTRONIC FORMS GENERATING SYSTEM OPERATIONAL PRACTICES FOR INSPECTION AND QUALITY CONTROL ASSOCIATION FOR INFORMATION AND IMAGE MANAGEMENT INTERNATIONALiv Foreword (This Foreword is not part of ANSI/
13、AIIM MS62-1999 Recommended Practice for COM Recording Systems Having an Internal Electronic Forms Generating System Operational Practices for Inspection and Quality Control.) As Computer Output Microfilm (COM) recording systems have evolved from the 1960s, they have gone through the exclusive use of
14、 hard (optical) forms initially to systems today that have either only software forms capability or an option of hard forms or software forms. Where systems only have software forms capability, there is a need to develop a standard for the components of a form that will test the image quality output
15、 of such systems. The software form will provide the same kind of image quality tests as the hard forms have, as specified in ANSI/AIIM MS1-1988 and ANSI/AIIM MS28-1983. The software forms may also complement the testing of systems that have both hard forms capability and soft forms capabil- ity. Th
16、e software test form exists as a bit map within the electronics of the page formatting section of the COM recorder systems, whereas the hard form is an actual picture on a substrate such as glass or paper. The other primary difference between the soft form and the hard form is in the fineness of det
17、ail that may be designed into the form. For example, in the case of the hard form, a resolution chart can be presented having any desired resolution pattern that is limited only by the photographic or fabrication methods used to create the forms patterns. The software form is limited by the smallest
18、 dot, or pixel, size that the re- corder is capable of producing. All images on the form are built from these basic dots so that the smallest imaging unit possible is a single dot. The thinnest line or space must be a single dot wide. The dot itself is generally larger than the allowable dot-to-dot
19、center spacing so that consecutive dots are smoothed to- gether, giving the appearance of a line segment (see Figure 1). Consequently, it may not always be possi- ble, in using a resolution test pattern, to resolve the finest element of the pattern that is made of single dot lines and spaces. The si
20、ngle dot space between a pair of lines will be partially filled in as a result of the dot-size-to-dot-separation ratio. It also puts limitations on the construction of some characters such as Japanese Kanji characters where lines and spaces are frequently only a dot wide. The test form described her
21、e is designed to test for this characteristic limitation and other quality requirements. This American National Standard consists of two parts. Part 1 describes the location and design of all the components (legibility fonts, resolution test patterns, density areas, etc.) of a software form for use
22、in testing the image quality output of COM recorder systems. Two test forms are described for COM sys- tems generating images on microforms by dot addressing methods. One of the software test forms is for systems having limited memory capability and is identified as Form 1 in this American National
23、Standard. The other form is for systems having greater memory capability and is identified as Form 2. Form 1 and Form 2 are shown in Part 1 of this American National Standard in Figures 3 and 4. The test forms have been designed so that they can be used to evaluate recorded images from any type of m
24、icrofilm recorder, such as cathode ray tube (CRT), laser scanner, light emitting diode (LED), etc. Part 2 of this document describes the preferred method for using the test form described in Part 1. The primary uses of the forms are to establish a baseline for image quality for a new COM recorder sy
