Final answer:
To add 'studios' with the specified formatting in graphic design software, select the text tool, set the font family to Arial Regular and the font size to 125, type in all caps, and position the text below the horizontal guide and between the vertical guides.
Step-by-step explanation:
To add the word studios below the horizontal guide and between the vertical guides in a graphic design software with the specified formatting, you would select the text tool and click on the desired position to begin typing. Make sure the font family is set to Arial Regular and the font size to 125. Transform the text to all caps either before typing, by enabling the caps lock, or after typing, by selecting the text and using the Type > All Caps option, depending on your software's capabilities. After typing 'studios' in all capital letters, you could then position it precisely below the horizontal guide and align it between the vertical guides as needed. If you need the text to conform to a specific path, such as a curve, Adobe Illustrator's Type > Type on a Path > Type on a Path Options could be utilized. Finally, if the project requires converting the text to vector outlines—for example, for printing or to prevent font substitution—you would use the Type > Create Outlines feature. Note that the Type > Area Type Options command is generally used for controlling the behavior of text within a predefined area, which might not be necessary unless the word 'studios' must be constrained within a particular space.
