Multi-Color Block Print Kit

Multi-block: a separate block per color, each printed in register on the fabric — the colors layer. Reduction: one block, cut for color 1 and printed across the run, then cut further for color 2 and printed again (the block is destroyed). Multi-block is repeatable (you can print more later); reduction is final. Both need precise registration.

Aligning each color's block to the previous print, exactly — a registration jig (a marked corner, a pinned guide) holds the block in the same position relative to the fabric for every print and every color. Misregistration = blurred colors. Registration is the multi-color printer's precision skill; a jig makes it reliable.

For layering colors (a yellow over a blue), the top color must be opaque (cover the one beneath) — transparent inks blend (yellow over blue makes green). Opaque fabric inks (with a white or pigment base) sit on top and stay true to color. Choose opaque for layered multi-color, transparent for blends. The ink opacity is a multi-color design decision.

A slightly yielding surface (a felt pad or a foam-under-cloth table) — it lets the block press the ink into the fabric (a better transfer) where a hard surface would print only the surface fibers. Professional fabric printers print on padded tables for this reason; the home printer adds a felt pad under a cloth cover. The pad improves the print's solidity.
