How to print a zine double-sided
double-sided printing simply means printing on both sides of the same sheet. For zines, the key extra step is telling the printer which edge to turn the paper around before it prints the back.
KUMIZINE · DUPLEX TEST SHEET
One sheet, two sides
Print both pages double-sided at 100% scale, then compare them after flipping left to right along the long edge. That is the whole idea to learn first.

How it should read after the flip
TOP EDGE stays on top
Both sides must show TOP EDGE at the top when the sheet is held the same way up.
Corners mirror across the fold
TOP LEFT on the front sits directly behind TOP RIGHT on the back.
Upside down? Wrong flip edge
Switch the duplex setting and print the test again.
In plain English
If the back of your zine prints upside down, your pages may be completely fine. Try changing Long-edge to Short-edge, or vice versa, and print one test sheet.

What is double-sided printing?
double-sided simply means printing on both sides of the same sheet.
For a zine, we also need to tell the printer which edge to turn the paper around before it prints the back side. That is the whole concept to understand first.
How does the paper actually flip?
Think of the sheet turning around one edge, like a hinge.
Printers usually call those two choices long-edge and short-edge flipping. Once you picture the paper turning physically, the setting becomes much easier to reason about.
Long-edge or short-edge?
Long-edge is like turning a page in a book.
Short-edge is more like flipping a notepad upward.
Which one is right depends on the way the sheet is oriented and how you expect the finished pages to read after printing and folding.
Try a one-sheet test
Print one double-sided Test Sheet before the full run.
Choose either long-edge or short-edge, print the front and back, and look at the result. If the back is upside down, switch to the other option and print the test again.
You now know the correct setting for this printer and this sheet orientation.
What if the result looks wrong?
If the back is upside down, try the other flip setting first.
If the front and back are upright but the pages themselves are paired differently from expected, check the page arrangement instead.
Kumizine calls that page arrangement on the sheet imposition. You do not need to arrange those pages manually when Kumizine has already created the file for you.
Why portrait and landscape can behave differently
When you rotate the sheet from portrait to landscape, its long and short edges swap position relative to the artwork.
That can change which printer setting gives you the result you expect. So a setting that worked in one orientation may need a fresh one-sheet test in the other.
You’re ready to print your zine
Once the double-sided Test Sheet looks right, you can move into the real print with much more confidence.
That small experiment separates a printing-direction question from a page-arrangement question, which makes the rest of the steps feel much simpler.

Test your printer before the full run
Use the Duplex Test Sheet to confirm long-edge vs short-edge flipping before you print the real zine.
What do you see?
Use this quick check to understand what the result is showing you before you change anything bigger.
| What you see | What it usually means | Try this |
|---|---|---|
Back is upside down | The paper flipped around the other edge | Try the other flip setting |
Front and back are upright, but pages don’t match | Page arrangement needs checking | Check the imposed layout |
It worked in portrait but not landscape | The sheet direction changed | Run the test again |
The goal is not to guess perfectly from memory. The goal is to learn what your printer is doing with one easy test.
This table shows a worked example of how the concept affects real sheet order, page order, or production decisions.
Common mistakes
Start with one sheet, not the whole zine
A tiny test is easier to understand than a full print run, and it tells you what the printer is doing immediately.
Use the result to guide the next step
If the back is upside down, switch the flip setting. If the pages themselves are paired differently, look at the layout logic next.
Re-test when the sheet orientation changes
Portrait and landscape can behave differently because the long and short edges shift relative to the artwork.
Run one quick double-sided check, then print with confidence
Kumizine includes a free double-sided Test Sheet so you can learn the right setting for this printer and orientation before you print the full zine.

What we check before we publish or update technical guidance
- •We compare the explanation against the same production rules Kumizine uses for page order, signatures, and print-planning where those rules apply.
- •We keep practical guidance tied to supported workflows rather than describing imaginary bindings, printer behaviour, or export features.
- •When a guide needs a worked example, we prefer first-party booklet, template, or layout examples taken from Kumizine’s own workflows.
