Abstract

Abstract A process for running width adjustment of adjacently positioned characters reduces the spacing of certain characters to enhance the visual impression of composed text. The process classifies the letter and symbols of the font into a plurality of groups according to their suitability for running width adjustment. The amount of running width adjustment to be provided for each pair of adjacent characters is established in accordance with their grouping. During composing, the running width of each character is determined. The characters are classified into the groups. The amount of adjustment to be provided is ascertained by reference to the group of the first character and the group of the second character of each adjacent pair and applied to the running width of one of the characters to reduce the spacing.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 137 words
A process for running width adjustment of adjacently positioned characters in a photocomposing machine to enhance the visual impression of the composed material, said process comprising the steps of: assigning the characters of a font into a plurality of groups in accordance with their suitability for running width adjustment; establishing the possibility and amount of running width adjustment to be provided for each combination of adjacently positioned character groups; determining the running width of each character to be photocomposed, subjecting the characters to be photocomposed to classification into the aforesaid groups; ascertaining, by reference to the group of the first character and the group of the second character of an adjacently positioned pair, the amount of running width adjustment to be provided; and applying the adjustment to the running width of one of the adjacently positioned characters.
Claim 2
Dependent Claim 137 words
A process for running width adjustment of adjacently positioned characters in a photocomposing machine to enhance the visual impression of the composed material, said process comprising the steps of: assigning the characters of a font into a plurality of groups in accordance with their suitability for running width adjustment; establishing the possibility and amount of running width adjustment to be provided for each combination of adjacently positioned character groups; determining the running width of each character to be photocomposed, subjecting the characters to be photocomposed to classification into the aforesaid groups; ascertaining, by reference to the group of the first character and the group of the second character of an adjacently positioned pair, the amount of running width adjustment to be provided; and applying the adjustment to the running width of one of the adjacently positioned characters.
Claim 3
Dependent Claim 40 words
The process according to claim 1 wherein the determination of the running width of each character is further defined as determining the running width of each character responsive to thickness of the character, the type face, and the type size.
Claim 4
Dependent Claim 30 words
The process according to claim 1 wherein the application of the running width adjustment is further defined as applying the adjustment to the first character of the adjacently positioned pair.
Claim 5
Dependent Claim 31 words
The process according to claim 1 wherein the application of the running width adjustment is further defined as reducing the running width of the first character of the adjacently positioned pair.
Claim 6
Dependent Claim 47 words
The process according to claim 1 wherein the assignment of the characters is further defined as assigning the characters into seventeen groups, sixteen of which contain characters that participate in running width adjustment and one of which contains characters that do not participate in running width adjustment.
Claim 7
Dependent Claim 32 words
The process according to claim 5 wherein the character assignment is further defined as assigning the characters participating in running width adjustment into sixteen groups each identified by a binary encoded number.
Claim 8
Dependent Claim 29 words
The process according to claim 6 wherein the character assignment is further defined as assigning the characters into sixteen groups each identified by a four bit binary encoded number.
Claim 9
Dependent Claim 37 words
The process according to claim 7 wherein the running width adjustment ascertainment is further defined as ascertaining the amount of running width adjustment by means of the binary encoded numbers of the first and second character groups.
Claim 10
Dependent Claim 47 words
The process according to claim 8 wherein the running width adjustment ascertainment is further defined as ascertaining the amount of running width adjustment by means of an 8 bit binary encoded number formed of the 4 bit binary encoded numbers of the first and second character groups.
Claim 11
Dependent Claim 47 words
The process according to claim 9 wherein 256 possible combinations of running width adjustment are established, wherein the combinations are stored in 128 bytes each identifying two running width adjustment amounts and wherein one bit of the 8 bit binary encoded number selects the proper adjustment amount.
