20 lb Bond Plotter is great for everyday use. And you can use it for large format printing. Always store inkjet media in a cool dry place. If the storage environment is different from printing conditions, permit the product to adjust before starting to print. Manage print media by the edges to prevent dirt and oils from contaminating the print area. Great results are achieved when operating at 65-85 degrees F and 25-70% Humidity. When printing with Bond Plotter Paper, always print on the preferred side of the media. The preferred side is always on the outside of the roll, unless otherwise noted. Inkjet Bond 20 lb is a wood pulp product and is not suitable for long-lasting archival purposes.Specification:Properties: 20 lb / 75gsmOpacity: 85%Brightness: 92
