Listings show 2-inch cores for many plotter and wide-format rolls and 3-inch cores for larger-format rolls.
The listings use both US pound-weight and metric units — for example, 20 lb and 22 lb, and metric values such as 80 g/m².
Some wide-format bond rolls list a paper brightness of 94 and opacity values reported up to 94% to help reduce bleed-through or show-through.
