Choosing Inks and Papers for Relief Printing

Why Ink and Paper Must Be Chosen Together

Relief printing asks a lot of two materials at once. You carve a block, roll ink across the surface, lay down a sheet of paper, and then press or burnish. The ink has to sit evenly on the raised areas, release cleanly when the paper touches it, and stay where it lands. The paper has to accept that ink without buckling, cockling, or drinking too much of it. Choose a mismatched pair — a stiff, slow-drying ink with a thin, unsized paper, say — and you'll spend the afternoon wondering why your lovely carving has come out patchy and grey.

The good news is that the choices are not complicated once you understand what each ink and paper actually does. What follows walks through the main families of ink and the paper qualities that matter, with a nod to what tends to work best in a British home studio where a kitchen table doubles as a press bed.

Water-Based Inks: Fast, Clean and Easy to Live With

Water-based relief inks are the default starting point for most home printers, and with good reason. They clean up with warm water and a little soap, they have almost no smell, and they dry within minutes on the paper. If you're printing in a spare room or at the kitchen table and you don't want solvent fumes drifting through the house, they are the sensible choice.

Their speed is both the strength and the difficulty. Because they dry quickly, you can layer colours almost immediately — useful for reduction prints or for overprinting. But that same quickness means the ink can start to set on your brayer and block while you're still working. On a warm day, or in a centrally heated room, you may get only a few minutes of open time before the surface turns tacky and begins to skip.

To get the best from them:

• Roll out small amounts at a time rather than a big pool of ink.
• Work briskly, and re-roll the block between every pull.
• Keep a spray bottle of water handy to mist the ink if it starts to skin over.
• Accept that very fine detail may need two or three passes to build up an even tone.

Water-based inks often look slightly translucent straight from the tube. That is not a fault — it just means the final colour depends on the paper beneath it. On cream or off-white stock, a blue may read greener than you expect.

Oil-Based Inks: Slower, Denser and Deeper in Colour

Oil-based relief inks are the traditional choice for anyone chasing rich, opaque, velvety blacks and saturated colour. They stay open far longer, so you can take your time rolling out, registering the paper, and burnishing. Their pigment load is usually higher, which means fewer passes for a solid, even coverage, and fine lines hold their crispness far better.

The trade-offs are practical. Cleaning up needs vegetable oil or a dedicated solvent, followed by soap and water; ventilation matters; and prints can take anywhere from a day to a week to dry properly, depending on humidity. In a small flat, that means finding somewhere flat and dust-free for the prints to sit — a spare bed covered in newspaper works well.

There is a middle path worth knowing about: water-miscible oil-based inks. These behave like oil inks on the block — long open time, dense colour — but clean up with soap and water. They are a genuinely useful compromise for the home studio, though they still need a little more drying time than pure water-based products.

Paper Weight: How Heavy Is Heavy Enough

Paper weight, given in grams per square metre (gsm), tells you how substantial the sheet is. For relief printing, the rough guide is:

• 80–100 gsm: fine for test pulls and proofs, but too flimsy for finished prints — it cockles and tears under burnishing.
• 120–160 gsm: a good proofing weight and usable for simple cards and small editions.
• 200–300 gsm: the sweet spot for most finished relief prints. Substantial enough to hold an even impression, still flexible enough to press into the block's recesses.
• 300 gsm and above: wonderful for a weighty, gallery feel, but heavy stock can resist hand burnishing and may need a proper press.

What matters most is not the number alone but how the sheet behaves under pressure. A 250 gsm paper with a soft, absorbent surface may print better by hand than a 300 gsm paper that is hard and glossy.

Texture, Sizing and the Surface That Meets Your Ink

The surface of the paper decides how much detail survives. Smooth, hot-pressed sheets give the sharpest transfer — every thin line and delicate mark arrives intact. Textured, cold-pressed or laid papers add character and a lovely tooth, but they can break up very fine lines and leave a slightly speckled look in flat areas. Neither is better; it depends on whether your image wants precision or texture.

Sizing is the other quiet variable. Sized papers resist ink absorption, so the ink sits on the surface and dries to a brighter, more saturated finish. Unsized or lightly sized papers drink ink readily, which can dull the colour and make even coverage harder to achieve. Japanese papers — thin, strong and often lightly sized — are excellent for hand burnishing and for chine collé work, where you glue a lighter sheet onto a heavier backing.

Testing Before You Commit

Before you print a whole edition, pull two or three proofs on different papers with the same ink. Compare how the ink sits, how the fine lines read, and how the sheet feels once dry. Note the pressure you used and the number of passes. A simple greaseproof-paper registration sheet, a clean brayer and a wooden spoon for burnishing are all you really need to make the test worthwhile.

Once you've found a combination that gives you clean edges and even, rich coverage, write it down. Ink, paper weight, pressure, passes — that small record will save you hours the next time you settle down to print.
