Introduction

The need to establish effective and reliable method of measuring image quality Alphanumeric computer output microforms. To obtain a stable quality fitness With the output of products, development of these methods is necessary. In the production process contains alphanumeric information microform, the most important thing is to be presented Clear and readable information to the user, for microform used both the original film (first generation) or copy sheet should be guided by this principle. GB/T 17294 specifies the method for measuring computer output microform (COM) quality, and the use of standards required by the method used A detailed description of the test slide and test data patterns. It is suitable for inclusion generated by a cathode ray tube, a light emitting diode or laser Variable data and microform format slides contained on fixed data. For the GB/T 18503-2008 consistent, effective Reduced scale range from 1.24 to 1.48. This section only applies to format slides COM recorder. This section describes the different systems and devices, in order to establish testing guidelines. For this reason, users in the use of low-end equipment can still maintain A certain level of operation. The method requires test slide and test data generated from the COM image generator. GB/T 117 294 Part illustrates the characteristics of the test slide and test data, Part 2 describes the use of the test slides and Test data quality Alphanumeric computer output microforms method of controlling. GB/T 17294.2-2008/ISO 8514-2.2000 Micrographics Alphanumeric computer output microform Quality control - Part 2. Method

1 Scope

GB/T 17294 specifies the use of this part of the quality slide format alphanumeric computer output microform (COM) will be The method of measurement. And provides a method to establish the most suitable image generator intensity (exposure) of. This section applies to the use of COM format slide recorder.

4 Overview of Methods

Images This method can be used for debugging COM systems to produce the desired future can be maintained as an everyday kind of device performance and stability method. If you use several sets of COM recorders, which have to ensure that they achieve the same performance COM recorders role. Firstly, the use of this standard in the first part of the testing required in the slide test chart No. 1 and No. 2 test chart to determine the measure Test whether the slide images to achieve the best focus. E-H pattern and density balancing area (see Figure 1) is used to determine the appropriate amount of exposure. Data character generator is used to set and Determination of the accuracy of registration data and test slides. Positioning grid can use to complete this step. Using the character E and H can adjust the picture occur The exposure device. Typically exposure value set by the user according to their needs. GB/T 17294.2-2008/ISO 8514-2.2000 ......
