Offset Paper Weight Comparison: What Should You Know?
What Is Offset Paper Weight and How Is It Measured?
When it comes to choosing the right paper for your printing projects, understanding paper weight is essential. Paper weight refers to the thickness or caliper of a sheet of paper, and it is typically measured in pounds (lb.), grams per square meter (gsm), or points (pt.). In this article, we will explore what offset paper weight is and how it is measured, as well as provide you with some useful comparisons of different paper weights.
What is Offset Paper Weight?
Offset paper weight is a term commonly used in the printing industry to describe the weight or thickness of a specific type of paper known as offset paper. Offset paper is a high-quality, uncoated paper that is commonly used for printing books, brochures, and other promotional materials. It is known for its excellent printability and smooth surface.
How Is Paper Weight Measured?
There are three main ways to measure paper weight: GSM, pounds (lb.), and points (pt.). Let’s take a closer look at each measurement method:
Understanding GSM (Grams per Square Meter)
GSM, or grams per square meter, is a universal measure of paper weight that is used worldwide. It represents the weight of a sheet of paper measuring one square meter. The higher the GSM value, the heavier and thicker the paper. For example, a 120 gsm paper will be thicker and heavier than an 80 gsm paper.
GSM is a reliable measurement method because it allows for easy comparison of different paper types, regardless of their size.
Pounds (lb.): Weight of 500 Parent Sheets
Pound, often abbreviated as lb., is a measurement method commonly used in the United States. It represents the weight of 500 sheets of paper of a specific type and size, known as the parent sheet. For example, if 500 sheets of a specific offset paper weigh 70 pounds, it is referred to as 70 lb. paper.
The pound measurement is often used for text or offset stock, which is the type of paper commonly used for inside pages of books and brochures.
Points (pt.): Thickness Measurement
Points, abbreviated as pt., is a measurement method primarily used for cover, board, and card stock. One point is equal to 1/1000 (.001) inches. For example, a 10 pt. stock is 0.01 inches thick.
Points are used to measure the thickness of thicker and more rigid paper stocks, such as those used for covers and business cards.
How Do Different Paper Weights Compare?
Now that we understand how paper weight is measured, let’s take a look at some common offset paper weights and how they compare:
Common Text (Offset) Stock Weights
| Paper Weight | GSM | LB. |
|---|---|---|
| 70 lb. | 105 | 70 |
| 80 lb. | 118 | 80 |
| 100 lb. | 150 | 100 |
Common Cover Stock Weights
| Paper Weight | PT. | LB. |
|---|---|---|
| 10 pt. | – | 250 |
| 12 pt. | – | 300 |
| 14 pt. | – | 350 |
These are just a few examples of commonly used offset paper weights. It’s important to note that there is no direct conversion between gsm, lb., and pt. measurements, so it’s always a good idea to consult conversion charts or consult with your printer or paper supplier to determine the best option for your specific needs.
In Summary
Understanding offset paper weight and how it is measured can help you make informed decisions when choosing the right paper for your printing projects. Whether you’re looking for lightweight text stock or heavyweight cover stock, considering the weight, thickness, and intended use of the paper can ensure that your prints turn out just the way you envision them.
How Do Different Offset Paper Weights Impact Printing Quality?
When it comes to printing, the paper weight you choose can have a significant impact on the final result.
