Rollerball vs Ballpoint Pens: Ink Differences and More

Low viscosity or high? Liquid-based or oil? When it’s all about the ink and explanations are clear as mud, what’s a well-intentioned pen shopper to do?

We have quick and easy answers! Whether you’re looking for a pen for yourself or as a giveaway for customers, wondering what the difference is between ballpoint and rollerball is a common conundrum. Considering we’re pen experts and you’re busy, we’re at the ready with everything you need to know. So what is the difference between a rollerball and ballpoint pen?

Here’s the Quick Answer:

Rollerball pens use water-based inks, and writing is sharper and more vibrant. Ballpoint pens use oil-based ink, and writing is lighter and more deliberate. There are benefits to each and reasons why a rollerball or ballpoint pen may be preferable in certain situations.

Look how nice that rollerball ink looks compared to the ballpoint! So, why are there so many ballpoint pens out there?

Ballpoint pen ink is preferred by so many because the ink:

• Dries fast
• Doesn’t smudge
• Doesn’t bleed through paper
• Comes out slower so the ink cartridge lasts longer
• Is less expensive

On the other hand, those who prefer a rollerball pen have their own strong leg to stand on.

Rollerball ink has its own unique advantages:

• Consistent ink flow, less skipping
• Less pressure needed means less hand fatigue and quicker writing
• Wider range of colours with water-soluble dyes
• Clearer line

And there you have it! No need to understand the mechanics of a pen or delve into history and trivia surrounding writing instruments, folks.

Thanks. Now, What Is Viscosity?

If you want to get into the weeds with us, here’s the “why” behind the difference between rollerball and ballpoint ink. Firstly, viscosity describes the flow rate of a liquid. Rollerball ink is a water-based liquid, where ballpoint ink is an oil-based liquid. Water-based inks are thinner, or lower viscosity. They flow faster. Oil-based inks are thicker, or higher viscosity. They flow slower. This makes rollerball ink vivid (more ink flow means the paper is more saturated) but also slower to dry and easier to smudge.
