The media could not be loaded.This is a sturdy, heavy paper stock and has a brightness rating of 96. I had previously purchased a 90 lb paper stock but it was no where near heavy enough for my projects. I searched again and I found this. It’s 100lb paper stock, but it’s much heavier than the 90lb. I think the industry makes it confusing because I think there is “Cover Weight” versus “Text Weight” and that’s where the confusion creeps in. It’s not always clear which is which. This time, I looked at the GSM weight metric. The 90lb stock I purchased first was 163 gsm. This paper stock is 271 gsm. That number is where I think you can probably find the differences if you need to find heavier stock.For Example—while all paper stocks are different—here is a random example of one paper stock to show how different a Cover versus Text weight can be:100lb Book/Text/Offset 150 gsm100lb Cover 270 gsmBig difference.I was worried that this paper might be too heavy to go through my printer, but it works just fine! I highly recommend it.
