ABSTRACT:
The present invention relates to the field of typography. In this field, it is desirable to quickly and efficiently determine certain key ratios between cap height and type size of a letter in a particular typeface, in order to create various aesthetic results. In situations where variations in typeface height normally cause problems, such as: matching specimens of typeface; filling vertical spaces; and dropping caps, among others, the task of determining this ratio is complicated by the fact that typefaces with the same point size may actually differ in height, and typefaces of the same name may vary in size according to the typesetting system which produces them. In such situations, the instant invention is particularly useful. In use, the present invention allows the typesetter, by aligning the device with the cap in accordance with the method of the present invention, and knowing two out of the following three measurements (index number, point size, and cap height) to correlate them so that the third measurement will be instantly available. Once the degrees of the index number is known, various functions such as sizing type, filling a vertical space etc., can be performed using the method of the present invention. The sequence of steps of the present invention may change, depending on the measurement that needs to be determined. However, the individual steps remain the same, whether the index number, cap height or point size is the measurement that needs to be determined.
