Understanding the role of calligraphy in the field of technology is crucial. Calligraphy software are considered modern platforms for this field. Since these applications have the capability to cover Nast’aliq and Sols scripts, it is necessary to know the influential styles of calligraphers on their production.
In this research using descriptive (analytical) method we have tried to explore and study the history of extensive calligraphy styles until now with emphasis on Nast’aliq and Sols in the course of letter designing for the software. Therefore after a brief introduction to the technical features of the software, the focus shifts to the origins of writing manners and styles of influential calligraphers on the application. The research aims at identifying the connection between the calligraphers’ writings with the common practices of calligraphy. In the case of Nast’aliq letter designing for the software, the styles of Abbas Akhavein (creator of Kelk software) and Amir Ahmad Falsafi (creator of Miremad and Chalipa softwares) with regard to the styles of Mirza Reza Kalhor's and Miremad Al hosna Ghazvini have been studied and In the case of Sols, styles of Iraqi calligrapher Hashem Baghdadi (creator of Kelk software) and Ali Shiri (creator of Miremad software) respecting the Turkish and Arabic styles of the 13th and 14th centuries. The result of the comparative and pictorial study of the above mentioned styles indicate that A. Akhavein’s calligraphy style is inspired by Miremad’s, And Amir Ahmad Falsafi’s style is close to the Kalhor’s. In the case of Sols script of the software, the way of Hashem Baghdadi is close to the Turkish calligraphers’ styles, such as Mustafa Raghem. It is also noteworthy that the Ali Shiri has followed the style of Hashem Baghdadi in Sols script.
