The article "Grid System as Backbone of Every Good Design. Part One" was written by Vera Fesianava in November 20, 2016. It tells her own experience as an technical editorial designer. She stresses the importance of using modular grid as a "layout to organize elements of a page." She calls it the "law of proportion." Also, alignment should be considered as one of the fundamental design principles that "maintains design integrity and clarity" that helps the reader maintain a visual understanding (order, clarity and rationality) of the text and graphics.

It is by creating a master page, with modular grid, as a template that is applied to all pages, with some modifications in each page according to the editorial requirements that makes the choices of the designer to present an individual or unique work. 

There are some guidelines and concepts (graphic design vocabulary) to learn. It is by the step-by-step process to follow when planning to design a zine. Some of the steps to consider are: paper margin, control margins, size and number of automatic geysers and extra anchor lines using horizontal and vertical guidelines. She explains the 12-column modular grid.
