Our CAD ink jet media, paper supply is custom-designed to meet the needs of architects, engineers, designers, artists, and blueprinters who use Computer-Aided-Design (CAD) applications and large-format ink jet printers, especially those manufactured by Hewlett-Packard. This 20 lb Inkjet Paper provides a uniquely high level of quality and consistency, with no variation in specification from roll to roll or order to order. All products are also backed by a comprehensive performance guarantee – and over 100 years of service to our industry. Rolls and sheets are bagged to protect against light, heat and moisture, then packed in rugged cartons designed to protect against the rigors of next-day and small-parcel shipments.
