Comparing Internal and Surface Sizing: What’s the Difference?

Have you ever wondered why some paper behaves differently when it comes to water and ink? The differences between internal and surface sizing are key in understanding how paper performance works.

Internal sizing involves mixing agents like alkyl ketene dimer (AKD) or alkenyl succinic anhydride (ASA) right into the pulp during the paper-making process. This method ensures that the entire sheet has consistent water resistance, which can really boost its stability and ability to resist moisture. It’s like prepping your paper to handle the real world.

On the flip side, surface sizing happens after the paper is formed. It’s a thin film that’s applied over the top, providing a nice boost for printability and keeping liquid from soaking in too fast. Want your paper to resist ink feathering? Internally sized paper definitely has the advantage. This means it’s stronger when moisture comes into play.

Here’s the key takeaway: internal sizing is better for overall resistance, while surface sizing is great for enhancing surface strength and lowering absorbency. If you’re into high-performance printing, surface sizing is your friend. But keep in mind—cost is a factor, too. Generally, internal sizing can hit your wallet harder with chemical costs, while surface sizing often uses more budget-friendly renewable starches.

In printing and artistic applications, choosing the right sizing method can affect paper performance and usability in significant ways.

Criteria for Selecting Your Ideal Paper Sizing Method

When it comes to picking the right paper sizing method, it’s important to really think about what you’re using the paper for. If you’re dealing with high-performance applications, you might want to lean towards surface sizing. It really boosts printability and makes the paper more resistant to liquids, which is super helpful for things like offset and security papers.

But if you’re working with more general types, like newsprint, internal sizing can be a better fit. It helps make the entire sheet resistant to moisture, which can be a lifesaver for everyday uses.

Cost is another factor to consider. Surface sizing often comes with a higher price tag thanks to the complex equipment needed, while internal sizing might rack up costs from the chemicals used. It’s a balancing act between what you need and what you can afford.
