Points, abbreviated as pt., find common usage in printing and bookbinding. They correspond to 1/72nd of an inch (equivalent to approximately 0.0139 inches or 0.3527 mm). Regarding digital printing, points are frequently employed for measuring font sizes, line spacing (leading), and various page elements.
One key role of points is ensuring consistent quality throughout a print job. By utilizing points to measure paper thickness, printers can guarantee that every sheet within a project possesses uniformity in thickness. This eliminates issues like printer jams and ink smudges.
Moreover, points also aid in estimating print job costs. As paper gets thicker, more points are amassed—leading to higher expenses due to increased ink usage and printing difficulty.
Though pounds or grams per square meter (GSM) might also be employed for measuring paper thickness by some printers, points remain the predominant unit of choice within the industry—especially for pricing purposes.
In books and printing at large, points hold significant importance. They play a crucial role in aligning text effectively on pages while enabling the creation of decorative borders and design elements. Points help establish consistency and ensure readability across projects while contributing to pleasing aesthetics that captivate readers’ or viewers’ attention.
