Overview
A designer printing proposals, postcards or direct mail can use this thick Hammermill sheet, built for color copiers and color laser printers. The surface is very smooth to help toner stick, and the sheets are white and acid-free. A guarantee against jams applies on high-speed digital printers.
Cover weight lets this stock handle thick toner coverage and two-sided prints. That weight limits some printers, and the listing points only to copiers and laser machines.
Who it's for
Print shops, offices and schools that run high-volume color jobs on thick paper get a smooth, bright sheet. Owners of inkjet or light-duty printers should confirm paper limits first.
Pros and cons
- Thick cover weight
- Smooth surface for toner adhesion
- Acid-free white sheets
- Jam-free guarantee stated
- Described for copiers and laser printers
- Weight may exceed some printer limits
- Brightness conflicts across the listing
Performance notes
A very smooth face gives toner a stable base, which matters for heavy coverage and photographic prints. Thick sheets resist showing through on double-sided prints, but each printer has a weight limit for its feed path. The maker backs the stock with a jam guarantee.
