Why do markers bleed through coloring book pages?

Most coloring books use standard paper, which is porous. Alcohol-based and heavy water-based markers contain solvents that easily soak through this porous paper to the other side.

What does 'single-sided with a black backing' mean?

It means the design is only printed on the front of the page, and the back of that same page is printed entirely black. This dark layer hides any ink that bleeds through, protecting the next design in the book.

Can I use watercolors in single-sided books?

While single-sided pages protect the next design, standard book paper will still warp or pill if you apply heavy water. We recommend markers, colored pencils, or gel pens instead.

Single-Sided vs Double-Sided Coloring Books: Why Bleed-Through Matters

Single-sided coloring books feature artwork printed on only one side of the page, ensuring that heavy marker ink does not bleed through and ruin another design on the back.

If you have ever spent hours carefully selecting the perfect colors and meticulously filling in a beautiful coloring book page, only to turn it over and discover that your ink ruined the design on the back, you know the heartbreak of double-sided pages.

The Problem with Double-Sided Coloring Books

Historically, publishers printed adult coloring books like standard novels: double-sided. This saves paper and makes the book feel thicker. However, this format was designed with colored pencils in mind. As the popularity of vibrant alcohol markers and gel pens skyrocketed, a major flaw in double-sided printing emerged: bleed-through.

Alcohol markers lay down heavy, vivid color. The solvents in these markers easily soak through standard book paper. If there is a design on the back of the page you are coloring, it will be completely ruined by ink splotches.

The Single-Sided Solution

The solution is simple but essential: single-sided printing. In a single-sided coloring book, every design is printed on the right-hand page (the recto), leaving the left-hand page (the verso) blank.

At The Paper Riot Store, we take this a step further. We don’t just leave the back of the page blank; we print it with a solid black backing. This dark layer acts as a visual shield. Even if your juiciest alcohol marker bleeds through the paper, the black backing hides the stain, keeping the book looking neat and protecting the next coloring page in the sequence.

More Than Just Bleed Protection

While preventing bleed-through is the primary benefit, single-sided pages offer another massive advantage: you can display your artwork!

When you finish a masterpiece in Modern Botanicals or complete a hilarious scene in Veggies Gone Wild, you shouldn’t have to choose between keeping it in the book or tearing it out and sacrificing the artwork on the reverse side. With single-sided pages, you can easily remove your finished piece, frame it, put it on the fridge, or give it to a friend without losing any other designs.

How to Protect Your Pages Further

Even with single-sided, black-backed pages, we always recommend practicing the “cardboard trick.” Simply take a scrap piece of heavy cardstock, cardboard, or even a few sheets of printer paper, and slide it directly behind the page you are currently coloring. This provides a 100% foolproof barrier against even the heaviest, wettest markers.

Conclusion

When shopping for a coloring book, always check the description for “single-sided pages.” It is the hallmark of a publisher who understands the practical realities of adult coloring. By choosing single-sided, bold and easy books, you guarantee a relaxing, frustration-free experience every time you uncap a marker.
