Test on a sheet you trust to find the culprit, and put a guard sheet behind thin pages. Paper weight helps, but sizing matters more. - URL: https://stationerytimes.com/guides/how-to-stop-fountain-pen-ink-bleeding/ - Category: How To - Author: Ellis Penhale - Published: 2026-10-31 - Updated: 2026-10-31 ![Five notebooks drawn to scale, labelled by paper: Midori MD, Hobonichi Techo on Tomoe River, Rhodia No. 16 80 g/m², Clairefontaine 90 g/m² and Moleskine 70 g/m²](https://stationerytimes.com/images/raster/how-to-stop-fountain-pen-ink-bleeding-illustration-16x9.png?v=b39bad10) *Five notebooks and their paper, drawn to scale at 1 mm = 1.24 px from each guide.* Original illustration made for this guide. © Stationery Times.

Midori's Japanese MD PRODUCT store gives 原産国 (country of origin) Made in Japan for the A5, as did the older Midori online store listing for the lined A5 (15294006).

Hobonichi's Japanese store listing for the 2027 English Original gives size, weight, pages and paper but no country of manufacture (it names one only for a free charm, made in China), and we found no retailer spec sheet that states it for the Original Book. Hunter Paper Co. says its Original Avec book is made in Japan by Hobonichi, but that is a different product.

Rhodia says all its notepads are manufactured at its plant near Mulhouse, Alsace; its 2024 French press kit places the plant at Illzach, on the edge of Mulhouse, since 1997. Retailers The Journal Shop, Dromgooles, Bruneau and Wonderpens also list the No. 16 as made in France.

It names three causes that work together, nib, ink and paper, and adds heavy pressure as a fourth. ## What do feathering, bleed-through and ghosting look like? **Feathering is fuzzy edges on the front, bleed-through is ink on the back, and ghosting is only a shadow of the writing.** Ferris Wheel Press describes feathering as soft, spidery edges and less definition, as if the line were smudged even when dry, because ink spreads along the paper fibres. Bleed-through leaves actual ink marks on the reverse, and in bad cases transfers to the next page. Ghosting means you can see the writing through the sheet without any ink reaching the back. A little ghosting is normal on thin paper such as Tomoe River, and it is a trade-off for low weight rather than a fault. Name the problem first, because the fixes differ: feathering points at absorbent paper, a broad nib or a wet ink, while bleed-through also points at thin paper. ## How do you stop fountain pen ink bleeding? **Change one thing at a time, starting with the paper, and test against a sheet you trust.** Ferris Wheel Press suggests keeping a reliable notebook as a control: if the problem disappears there, the paper is the culprit. 1. **Test the same pen on a sheet you trust.** Write a few lines in a notebook that has never given you trouble. If the lines stay crisp there, the paper you were using is the problem, so start with step 2. ![The same blue writing feathering on plain white paper but staying crisp on a cream fountain pen notebook page](https://stationerytimes.com/images/how-to-stop-fountain-pen-ink-bleeding-test-on-a-trusted-sheet.svg?v=078fbadc) *The control test: if a trusted sheet stays crisp, change the paper first.

The section below compares them. ![A hand writing crisp blue lines on a cream pad of fountain pen paper](https://stationerytimes.com/images/how-to-stop-fountain-pen-ink-bleeding-use-fountain-pen-paper.svg?v=8046380f) *Paper made for fountain pens keeps ink on the surface. Original illustration made for this guide. © Stationery Times.* 3. **Use a finer or drier nib.** A broad nib or a wet feed lays down more ink than weak paper can hold. ![A broad nib drawing a thick blue line, crossed out, beside a fine nib drawing a thin line, ticked](https://stationerytimes.com/images/how-to-stop-fountain-pen-ink-bleeding-use-a-finer-nib.svg?v=7ead8775) *A finer nib puts less ink on the page. Original illustration made for this guide. © Stationery Times.* 4. **Try a drier, less saturated ink.** Wet, heavily saturated inks show up weak paper first. Change the ink only after the paper and nib, so you know which change worked. ![A dark saturated ink bottle with a feathered line, crossed out, beside a lighter ink with a crisp line, ticked](https://stationerytimes.com/images/how-to-stop-fountain-pen-ink-bleeding-try-a-drier-ink.svg?v=f3c1c9ca) *A drier, lighter ink spreads less on absorbent paper. Original illustration made for this guide. © Stationery Times.* 5. **Write lightly.** Pressing down pushes out more ink and opens the nib. Pilot says a fountain pen needs almost no pressure, so let the pen rest on the page under its own weight. ![A hand writing a thin blue line with a fountain pen resting lightly, a downward pressing arrow crossed out](https://stationerytimes.com/images/how-to-stop-fountain-pen-ink-bleeding-write-lightly.svg?v=e0a5ee60) *Let the pen glide: pressing pushes out more ink. Original illustration made for this guide. © Stationery Times.* 6. **Slide a guard sheet behind thin pages.** A spare sheet behind the page you are writing on catches any ink that comes through. It protects the next page but does not stop the bleed itself. ![A spare white sheet slid behind a cream page with blue writing](https://stationerytimes.com/images/how-to-stop-fountain-pen-ink-bleeding-add-a-guard-sheet.svg?v=b025f311) *A guard sheet saves the next page, not the one you write on. Original illustration made for this guide. © Stationery Times.* **Avoid coated office paper such as fax, thermal and inkjet paper.** Pilot warns that its coating can clog the nib, which is a different problem from bleeding. Ferris Wheel Press is the source for steps 1 to 4 and 6, and Pilot for step 5. ## Which paper stops fountain pen ink bleeding? **Paper made and sized for fountain pens, whatever its weight.** Midori says its MD Paper resists feathering and bleed-through, and the Rhodia No. 16 and MD Paper pads are both 80 g/m². Clairefontaine's staplebound notebooks use 90 g/m² paper. Tomoe River S is only 52 g/m² yet resists bleed-through because the sheet is coated and sized, though writing shows through and dries slowly. Galen Leather says the 68 g/m² version shows bleed-through and ghosting less, while the 52 g/m² shows sheen better. The Moleskine Classic Large uses 70 g/m² paper, the lightest common hardcover paper in our [best notebooks for fountain pens](https://stationerytimes.com/guides/best-notebooks-for-fountain-pens/) guide, and reviewers report feathering and bleed with wet inks. For the weights themselves, see [paper weight explained](https://stationerytimes.com/guides/paper-weight-gsm-explained/). The guides for each notebook are the [Midori MD Notebook A5](https://stationerytimes.com/guides/midori-md-notebook-a5/), [Hobonichi Techo Original](https://stationerytimes.com/guides/hobonichi-techo-original/), [Rhodia No. 16](https://stationerytimes.com/guides/rhodia-no-16-dot-pad/), [Clairefontaine 1951](https://stationerytimes.com/guides/clairefontaine-1951-staplebound-notebook/) and [Moleskine Classic](https://stationerytimes.com/guides/moleskine-classic-notebook/). ## Which nib and ink bleed least? **A fine nib with a drier, less saturated ink.** Ferris Wheel Press says broader nibs and wetter feeds lay down more ink, and that a wet or heavily saturated ink is less forgiving on everyday paper, so a different ink can fix the same pen and paper. Our [nib sizes explained](https://stationerytimes.com/guides/fountain-pen-nib-sizes-explained/) and [fountain pen ink properties explained](https://stationerytimes.com/guides/fountain-pen-ink-properties-explained/) guides cover both. If a pen skips after writing on coated paper, see [how to fix a fountain pen that won't write](https://stationerytimes.com/guides/how-to-fix-a-fountain-pen-that-wont-write/). ## Frequently asked questions ### What is the difference between feathering, bleed-through and ghosting? Feathering is ink spreading sideways along the fibres into fuzzy lines. Bleed-through is ink reaching the back of the sheet. Ghosting is only seeing the writing through the page, which Ferris Wheel Press calls normal in small amounts. ### Does heavier paper always stop bleeding? No. Tomoe River at 52 g/m² resists bleed-through because it is coated and sized, while some 70 g/m² papers bleed. Sizing, which keeps ink on the surface, matters as much as weight. ### Is Moleskine paper good for fountain pens? Usually not. Its 70 g/m² paper often feathers and bleeds with fountain pen ink in published reviewer tests, especially with wet inks and broad nibs. ### Will a guard sheet stop bleed-through? No. Ferris Wheel Press says a guard sheet behind the page won't stop ink bleeding through, but it keeps the next page from being marked. ### Why does my fountain pen feather on copy paper but not in my notebook? Copy paper is usually more absorbent and less sized than fountain-pen paper, so ink wicks into the fibres. Try a finer nib or a drier ink, or keep a notebook made for fountain pens. ### Can I write with a fountain pen on receipts or inkjet photo paper? Pilot advises against it: fax, thermal and inkjet-coated papers can scrape coating into the nib and clog it, so flush the pen if it starts to skip. ## Sources - [Ferris Wheel Press: Paper Matters, Bleedthrough & Feathering (causes, nib, ink, pressure, control sheet, guard sheet; read October 31, 2026)](https://ferriswheelpress.com/blogs/ferris-wheel-press-blog/paper-matters-bleedthrough-feathering) - [Pilot Japan FAQ: ink breaks up on fax, thermal and inkjet paper (read October 31, 2026)](https://www.pilot.co.jp/support/fountain/post_29.html) - [Pilot Japan FAQ: precautions when using a fountain pen (little pressure needed; read October 31, 2026)](https://www.pilot.co.jp/support/fountain/1120630708373.html) - [Galen Leather: Why Tomoe River paper is the number one fountain pen paper (52 and 68 gsm, coated; read October 31, 2026)](https://galenleather.com/blogs/news/tomoe-river-paper) - [JetPens: MD Notebook A5 Dot Grid (Midori's fountain-pen friendly claim)](https://www.jetpens.com/MD-Notebook-A5-Dot-Grid/pd/26421) - [MD PRODUCT (Midori, Japan): MD Paper Pad A5 (80 g/m²)](https://md-product.com/products/md-paper-pad-a5) - [Rhodia: dotPad No. 16 (80 g/m² paper)](https://www.bloc-rhodia.com/fr/basics/37-137-dotpad-bloc-notes-agrafe.html) - [JetPens: Tomoe River S 52 gsm loose-leaf paper, A5](https://www.jetpens.com/Tomoe-River-S-52-gsm-Loose-Leaf-Paper-A5-Blank-White-100-Sheets/pd/34674) - [Goulet Pens: Clairefontaine Classic Staplebound A5 Notebook, Graph (48 sheets, 90 g)](https://gouletpens.com/products/clairefontaine-classic-staplebound-a5-notebook-graph) - [BIC Graphic: Moleskine Classic Notebook Large (13 × 21 cm, 240 pages, 70 g/m²)](https://web.archive.org/web/20251206063026/https://www.bicgraphic.com/ee/moleskine-large-classic-notebook-ruled-paper-3460015056.html) - [stefanv.com: A Comparison of Fountain Pens, Inks, and Papers (Moleskine test)](https://www.stefanv.com/pens/paper_tests.html)
