The work
9、of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-government
10、al, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The mai
11、n task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Att
12、ention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

13、 SC 2, Application issues. This first edition cancels and replaces ISO/TS 12029:2007, which has been technically revised. ISO 12029:2010(E) ISO 2010 All rights reserved vIntroduction This International Standard discusses issues and provides guidance for the design of forms that are used for electron
14、ic capture of handwriting information. Features include colour dropouts, type fonts, printing screen tints, line width, data storage and other interrelated issues. It is necessary to balance conflicting requirements of user-friendliness and electronic capture. Making a form appealing by use of colou
15、r or graphics could assist users when they complete the form but could also decrease the forms scannability or other automated, related functions. This conflict might require compromise in the design of a form. While this International Standard focuses on the design and structure of paper-based form
16、s, it is worth noting that the design and structure of electronic based forms can have different characteristics, ensuring usability and readability. The user is advised that use of these specifications when developing paper-based forms while keeping in mind that electronic forms can be easily repli
17、cated in an electronic format (with the same content as in the paper-based form), but with differing fonts and spacing.

18、 management systems (EDMS) 1 Scope This International Standard specifies requirements concerning the design of forms for user friendliness, with optimal machine readability for processing by electronic document management systems (EDMS). These requirements are limited to forms using roman characters

26、nflict with the most machine-readable form. For example, in a user-friendly layout, the following items, all interspersed with printed instructions next to specific areas, might be desirable: large print, colour-coded areas, and areas to be completed with both alphabetic and numeric information. How
27、ever, in a form designed for an electronic image management system (EIM), strict segregation of spaces for numeric and alphabetic information and instructional text within dropout colour areas can all be essential features. Optimum design can require a compromise between ideal user and scanner requi
28、rements. All logically connected information should be placed on the same page. 4.2 Data storage requirement The designer should be aware of the impact on data storage requirements of line borders, screened tints and logos or other design elements with large areas of reversed print. Reversed print w
29、ill make heavy demands on data storage. For all designs, particularly those having large areas of reversed print, the amount of data storage required should be determined and compared to the amount of data storage available within the system. ISO 12029:2010(E) ISO 2010 All rights reserved 34.3 Page
30、format On each page of a form, the margin all around should not be less than 10 mm. If the document is bound, padded or has punched holes or die cuts, the margin at that edge should be not less than 25 mm, and holes and die cuts should be restricted to that margin. Text and entry fields should not b
31、e within 6,5 mm of any crease or perforation. 4.4 Typeface and font 4.4.1 Typeface There are two styles of typeface commonly used on forms, serif and sanserif, as illustrated in Figure 1. E E a) Serif b) Sanserif Figure 1 Comparison of serif and sanserif typefaces Serif style is designed for ease of
32、 legibility, has variable line width within a character and a cross-line finishing a stroke of a letter. Sanserif has uniform line width within a character and no cross-lines. It is the style used in ISO standards. Serif type will inherently take more data storage capacity in a compressed image than
33、 sanserif type because more information has to be recorded for each character. With the most commonly used compression techniques, approximately 10 % more storage is required for a page printed in serif, as compared with one printed in sanserif type. Sanserif generally requires less horizontal line
34、space and more vertical height than the same point size serif type. Because of its uniform line width, it is preferred for photocopying, microfilming and scanning. For forms which might be used in optical character recognition (OCR) applications, sanserif typefaces should be used. For information on
35、 a form that is not required to be captured by scanning, the style of typeface used is not important. 4.4.2 Symbols An OCR program can use a particular symbol to prompt an action. The form designer should be aware of any such symbols and avoid their use other than as a prompt. 4.4.3 Spacing In types
36、etting, character spacing can be either fixed or proportional. In fixed typesetting, each character takes up equal horizontal space. Proportional typesetting allows for characters of different width, such as that of “i” compared with “w” and automatically adjusts space between the individual charact
37、ers to give a more natural appearance. There should be a clear gap between characters. The recommended minimum gap is not less than the width of the vertical stroke of characters of the font. ISO 12029:2010(E) 4 ISO 2010 All rights reservedThe designer should also be concerned with vertical spacing
38、requirements of an OCR system. Although 4,2 mm vertical spacing is usually sufficient for typewritten entries, at least twice that amount of space is necessary for hand-printed entries and for separating entries for OCR. 4.4.4 Character pitch Form design should allow no more than 0,4 characters per
39、millimetre for character pitch. 4.4.5 Character size In the printing industry, type size is usually specified in millimetres. In a computer or typewriter, type size is usually indicated in points. Fortunately, the printing industry is familiar with both systems and can easily translate requirements.
40、 The point (0,35 mm) is a unit derived from the height of metal slugs, once commonly but now rarely, used to set type. The size of character is not directly related to point size. For a given point size, the actual heights of the same upper-case character can be different for various typefaces. Ther
41、e is also variation in the ratio of heights of lower-case “e” to upper-case characters. This means that for a given point size, even if upper-case characters of two different typefaces have the same height, there is a possibility that this may not be so for lower-case characters. Since it is the siz
42、e of the lower-case characters that will limit scannability, minimum acceptable point size should be determined by the height of the lower-case “e”. The recommended minimum height of the lower-case “e” is 1,4 mm. If the EIM system is used as a transfer medium as part of overall processing of the inf
43、ormation extracted from a form, the minimum type size used shall allow for any degradation of image quality resulting from subsequent parts of the process. 4.4.6 Weight The weight of a type font is its relative line thickness, ranging from light to extra bold. Font weight directly affects the number
44、 of dots or pixels used to display a character of an electronic image. Different weights can also be used to emphasize or reduce significance of text blocks or captions for the user. 4.4.7 Type family Design variations on a basic typeface can include italic, condensed, expanded and others. Form desi
45、gners should try to keep the number of type families used within a form to a minimum to project an uncomplicated appearance that is pleasing to the eye. EIM systems and particularly OCR software can also benefit from limited use of type families. 4.5 Machine-printed stylized information 4.5.1 Genera
46、l Information may be presented on a form as a bar code or in OCR or MICR characters. These bar codes and stylized character sets are especially designed for automated processing and are machine readable with high accuracy. Machine reading is not always wholly accurate. The degree of accuracy achieva
47、ble can be improved if forms have error-checking features built into their design. Whenever possible, forms should be designed to use a second source of information for cross checking. When calculation is involved, both subtotal and entry figures should appear on forms so the processing system can r
48、ecalculate the subtotal to compare it with the amount read. Other examples of information for cross checking are account number/customer name, version number/issue date.
