“Substance weight” in the printing and paper industry refers to the physical weight of paper. More specifically, it measures how much paper there is in an area – for instance if 100 sheets of 8.5×11 bond paper are stacked against each other with no gaps between sheets, their combined substance weight would equal 11#.
Substance weight refers to the base weight in pounds of 500 sheets cut to their basic sizes in one ream of paper, cut following standard sizes. When ordering bond paper, it is crucial to be mindful of its substance weight since thickness directly correlates with this measurement. Traditional copy paper typically weighs 20 lb bond paper, which equals 75 grams/m2.
In addition, substance weight provides a standardized method of comparing the physical weight of various paper types. This method is critical as paper’s physical weight impacts its properties such as thickness, stiffness, and durability.
Consideration should be given to substance weight when selecting bond paper, as this determines its thickness and durability. Heavier papers tend to be more resistant to tearing and creasing, making them suitable for documents handled frequently or subjected to rough treatment; lighter papers buckle or warp less when exposed to moisture – perfect for documents exposed to the elements.
