I publish a monthly Christian magazine and I use a different color each month. It helps to keep the months separate from the previous month. It is great quality and a great price especially when it is on sale or when it has a rebate offer with it. I like the selection of colors and I try to coordinate the holiday months with paper that goes with that holiday like I use green for Christmas and red for February and Lavender for Easter. It is also easy to staple the pages together which is a great plus.
We use Staples pastel copy paper weekly for church bulletin announcements. We print on both sides without any bleed-through and it feeds equally well through a Xerox laser printer and a Riso inking system. It also feeds perfectly through the Pitney Bowes folding machine without a hiccup. I watch for it to go on sale and buy it in bulk.
I like to use different colors for different print jobs. It also makes it easier to designate a certain color for projects that you can find instantly.
