Whats the difference between Cover and Book ?

The terms “Cover” and “Book” refer to different types of paper stock commonly used in printing, and they have distinct characteristics:

  1. Cover Stock:
    • Thickness: Cover stock is thicker and heavier than book stock. It’s often referred to as cardstock.
    • Usage: It is primarily used for things that need sturdiness, such as business cards, postcards, flyers, and covers for books or catalogs. The extra weight makes it more durable and gives a premium feel.
    • Weight: Cover stock is typically measured in pounds (lb), and weights commonly range from 80lb to 120lb. For example, 100lb Cover is thick and stiff.
  2. Book Stock:
    • Thickness: Book stock is lighter and thinner than cover stock. It’s more like the paper you find in the pages of a book or magazine.
    • Usage: It is typically used for interior pages of books, brochures, newsletters, or catalogs. It’s designed for easy page-turning and reading.
    • Weight: Book stock is also measured in pounds but is much lighter, typically ranging from 50lb to 100lb. For example, 100lb Book is significantly thinner than 100lb Cover.

Key Difference:

Can you write on 100lb Gloss Cover or Book ?

Yes, you can write on 100lb Gloss Cover or Book paper, but it may not be as easy as writing on uncoated paper. The gloss coating can make it more difficult for certain pens or pencils to leave a mark. For best results, use a permanent marker or a pen with quick-drying ink (such as a ballpoint or gel pen). Standard pencils and some inks might smudge or not adhere well to the glossy surface.

I’m confused because I see 100lb Gloss Cover and 100lb Gloss Book.. I thought 100lb was the thickness

I can see why that would be confusing! The 100lb weight on both Gloss Cover and Gloss Book refers to the basis weight of the paper, but these two types of paper have different thicknesses and purposes despite both being labeled “100lb.”

Key Points:

Why They’re Different in Thickness:

In Summary:

Even though both say “100lb,” 100lb Gloss Cover is much thicker and stiffer than 100lb Gloss Book, because cover stock is measured using a smaller sheet size, making it denser. Think of 100lb Cover as being for sturdier projects like postcards or business cards, while 100lb Book is more for magazine pages or brochures where you want flexibility.

Which one can be used in a mailing service?

Both 100lb Gloss Cover and 100lb Gloss Book can be used in a mailing service, but they serve different purposes depending on the type of mailing piece you are creating:

100lb Gloss Cover:

100lb Gloss Book:

When to Use Each for Mailing:

For a self-mailer, where the piece isn’t enclosed in an envelope, 100lb Gloss Cover would be a better option due to its durability in the postal system. If you’re mailing something in an envelope, 100lb Gloss Book might be preferable because it’s thinner and lighter, which can help reduce mailing costs.
