Thank you for your question about Hammermill Color Copy Paper. This paper is ideal for double side color printing.
Hammermill Color Copy Paper is a 28 lb. paper, so it's little heavier than standard office paper. This is so the page is opaque when viewed from either side, and to prevent ink bleed through. Not all inkjet printers can accommodate heavier paper without jamming. If your printer can handle 28 lb. paper, Hammermill provides excellent results at an economical price.
If your printer can't accommodate 28 lb. paper, I recommend Polaris Premium Multipurpose Paper or Navigator Platinum Paper. These papers are lighter than the Hammermill paper, but still produce excellent double sided prints.
Hope this answers your question!
