How block printing on linen actually works

The linen tea towels at Jasper Pinecone are block-printed by hand each season. Customers often ask how the process works, partly out of curiosity and partly because they want to know whether the print will last. Here's an honest account of what's involved.

Carving the block ¶

The printing block is carved from linden wood, which is soft enough to cut cleanly but dense enough to hold fine detail over a long print run. The maker draws the design directly onto the wood surface and cuts away the negative space using a set of gouges. For a botanical motif with fine stems and seed heads, this can take several hours.

Once the block is carved, a test print is pulled on a scrap of linen to check the registration (how cleanly the block transfers to the fabric) and the detail. If a line is too fine, it may not print consistently across a full run. The maker adjusts the carving until the test print is clean.

The printing process ¶

The linen is pinned flat to a padded printing table. The maker applies water-based ink to the block using a roller, positions the block by eye, and presses it firmly and evenly onto the fabric. Each impression is made separately; there's no mechanical registration guide, so slight variations between prints are normal and expected.

After printing, the fabric is left to dry flat before the ink is heat-set using a domestic iron. Heat-setting bonds the ink to the linen fibres rather than leaving it sitting on the surface, which is what gives the print its wash durability. A print that hasn't been properly heat-set will fade significantly after the first wash.

Why the print holds ¶

Water-based textile inks, when properly heat-set, bond at a molecular level with natural fibres like linen and cotton. The result is a print that softens slightly with washing (the ink becomes part of the fabric rather than a coating on top of it) but doesn't fade or crack the way a plastisol or screen-printed design might.

The autumn 2026 print has been tested through ten machine washes at 40°C with no significant colour loss. The maker recommends washing at 30°C to be safe, but the print is enough to handle regular kitchen use.

The autumn 2026 tea towels are on the shelf now, printed in warm charcoal on undyed Irish linen. The run is limited to what the maker produced in a single print session, so once they're gone, the next design won't be ready until spring.
