The first step of the printing process was to print the days of each month. In this case, being a variable content from month to month, we opted to do the printing with a Xerox Versant 180 digital dry toner press.
The month numbers appear with the Parnaso Mono font created by Feliciano Type [unpublished at the time of printing]. It is a monospaced serif font, which allowed us to have a controlled structure of the space that days within weeks will occupy on each calendar page.
