F. Support tools and measurementsThere are two separate functions of form creation: forms designand forms description. Any form can be converted to anelectronic form stored on the system by describing it in FormsDescription Language (FDL).Forms design involves laying out and measuring a form and isonly a peripheral concern of this guide. A forms design ruler isprovided for the forms designer.Forms design rulerThe forms design ruler is used for the following:• Measuring character and line spacings• Converting forms from one type of paper to another.The ruler has eight scales, four on the front and four on theback, as shown in table F-1.Table F-1. Standard formats and spacingsSide 1 Formats/spacingScale 1–10/inch Standard computer output character spacing; can also be usedfor measuring inches, graduated in tenths.Scale 2–6/inch Standard computer output line spacing (6 lpi).Scale 3–8/inch Standard computer output line spacing (8 lpi).Scale 4–12/inch Can be used for 12 cpi or 12 lpi.Side 2 Formats/spacingScale 5–13.6/inch Default character spacing on Xerox laser printing systems.Scale 6–8.1/inch Default line spacing on Xerox laser printing systems (66 linesper landscape page).Scale 7–10.7/inch Line spacing on Xerox laser printing systems (88 lines perlandscape page).Scale 8–15/inch Can be used for 15 cpi or 15 lpi.The scales can be used for either character spacing or linespacing. For example, scale 1 can be used for either 10characters per inch (cpi) or 10 lines per inch (lpi).XEROX 4050/4090/4450/4650 LPS FORMS CREATION GUIDE F-1
