Why Registration Decides the Quality of Your Edition

Every multi-colour lino print lives or dies by registration. You can carve beautifully, mix gorgeous inks, and still end up with a run of prints that look muddled because the yellow sits half a millimetre to the left of where it should. The good news is that registration is a craft skill like any other, and a few sensible habits will carry you through an entire edition with crisp, consistent alignment.

The principle is simple: each layer must land on the paper in exactly the same position, every single time. The challenge is that paper shifts, blocks slide, and your hands are never quite as steady as you would like. So rather than trusting your eye, you build physical constraints that make misalignment difficult.

Start With a Registration Jig You Trust

The most reliable setup for relief printing is a flat board with stops that hold both the block and the paper. Cut a piece of 6mm MDF or birch ply slightly larger than your block. Glue two straight strips of the same board along two adjacent edges to form an L-shaped corner — one stop for the block, one for the paper. If you place the block against the corner and the paper against the same corner, every impression sits in the same relationship.

For this to work properly you need your paper cut to a consistent size, with square corners. Trim your whole edition to size before you print anything, using a sharp blade and a metal straight edge. A stack of paper that varies by two millimetres at the edge will produce registration drift you cannot diagnose by looking at the print alone.

If you prefer to print off the block rather than in the jig, fix the block to the board with double-sided tape or a couple of small strips of masking tape on the reverse, and mark the paper position with pencil lines. The pencil lines wear away, though, so a physical stop is worth the extra ten minutes of making.

Marking Systems: Tabs, Crosses and Pin Bars

When you cannot corner a block — for instance with a large or irregular shape — you need a marking system that transfers from layer to layer.

• Kentō tabs: the traditional Japanese method. Carve a small right-angle notch into the same corner of every block before you begin cutting your image. Lay the paper in the notch and you have a self-aligning corner that costs you nothing but a few minutes of carving.
• Registration crosses: carve a fine cross or corner mark in the margin of each block. Print the first layer, then align each subsequent block by matching the marks on the block to the marks showing through from the layer beneath.
• Pin registration: tape a sheet of acetate to the press bed or board, punch two holes in the acetate and in every sheet of paper, and thread a pin bar through both. This is the most accurate system available and is ideal if your edition is large or your layers are numerous.

Whichever you choose, apply it to every block at the same stage of carving. Adding a tab to a finished block is fiddly and easy to get wrong.

Paper Handling and the Things That Mimic Misregistration

Not every alignment problem is a registration problem. Before you adjust your jig, check these common culprits:

• Paper stretch: damp or heavily inked paper expands between layers. Print your layers in quick succession, or let the paper dry fully and flatten it under weight before the next run.
• Slip sheets: a clean sheet of newsprint between the print and the press blanket stops ink transfer and helps the paper stay put.
• Uneven pressure: if your press or baren is heavier on one side, the paper can drag. Check by printing a single layer and looking for a ghosted double edge.
• Thick ink: over-inked blocks squidge outward under pressure, pushing the image slightly wider than the block itself. Aim for a thin, tacky layer that sounds like a quiet kiss when you roll it.

Printing Order and Registration Discipline

Print your lightest colours first. Pale yellows and greys are far more forgiving of a half-millimetre drift than a dense black, and printing them first means subsequent layers cover any minor edge softness. If you are using a key block — the dark outline layer — decide whether it goes first or last and stay consistent for the whole edition.

Work in small batches and pull a proof every ten or so prints. Number them lightly in pencil in the margin, or keep a tally on a scrap of paper. If registration starts to drift, you will spot it on the proof rather than on print forty-seven.

Finally, keep your hands and the jig clean. A smear of ink on the stop, a grain of dried lino under the paper, or a slightly bent corner will all nudge your alignment. Wipe down the board between colours, and store your blocks flat with the carved face up. Do these small things consistently and multi-colour printing stops feeling like a gamble and starts feeling like a craft you can repeat — edition after edition.
