Block Printing — India's Living Craft Tradition.

Making a block-printed cushion cover involves six stages. (1) Fabric preparation: cotton is washed, de-sized, and dried to remove factory finish. (2) Block preparation: teak or sheesham wood blocks are soaked in mustard oil for 2–3 days before printing to prevent dye absorption into the wood. (3) Colour mixing: reactive dyes are mixed with sodium alginate (a natural thickener from seaweed) to the correct viscosity for clean block registration. (4) Printing: the block is pressed firmly and evenly onto the dye pad, then positioned on the fabric and pressed by hand or with a hammer. Each colour requires a separate block and a drying interval. (5) Fixation: printed fabric is steamed or cured to bond the dye to the fibre. (6) Washing: excess dye is washed out in cold water, dried in shade, then cut and stitched into covers.

The quality indicators for block-printed textiles, in order of importance: (1) Registration accuracy — the gap between adjacent block stamps should be minimal and consistent; a premium print shows <1mm registration error; (2) Colour saturation — dye should penetrate the full fabric depth, not sit only on the surface (pull a thread: the core should be coloured, not white); (3) Crispness of edge detail — fine lines in the pattern should be sharp, not blurred by over-inking the block; (4) Pattern repeat consistency — the repeat should align across the full fabric length within ±3mm; (5) Dye fixation — a quality reactive-dye print loses <10% colour on first cold wash; a poorly fixed print bleeds significantly. SOISU block-print covers are inspected against these criteria at the Sanganer workshop before dispatch.

Variation in hand-block printing is an inherent characteristic of the handmade process and is universally recognised as a quality indicator of genuine craft — not a defect. The variation arises from natural differences in hand pressure, ink viscosity as the print session progresses, and wood grain variation between blocks. In fine block printing, two adjacent repeat stamps on the same fabric will never be pixel-perfect — this is what distinguishes hand-printed work from screen printing or digital printing. International luxury brands (Liberty London, Hermès toile) command premium prices precisely because of this 'human hand' quality. SOISU's product pages explicitly disclose that each block-print cover is hand-printed and that slight registration variation is a feature. The QC photograph before dispatch shows the actual unit being shipped.

Natural dye block printing uses pigments extracted from plant, mineral, or insect sources — indigo (from Indigofera tinctoria), madder root (red/terracotta), pomegranate rind (yellow-gold), iron mordant (black), and resist-paste from black mud (dabu printing) are the classic Rajasthani palette. Natural dyes produce muted, earthy, historically authentic tones that fade gradually and gracefully with washing — developing what collectors call 'patina.' Chemical (reactive) dye printing uses synthesised compounds that bond permanently to fibre, producing more intense, saturated colours that are more stable under UV light and repeated washing. For decorative home textiles in Indian conditions, reactive dye is the practical choice; for collectors and heritage-textile enthusiasts, natural dye block prints are the premium option. SOISU currently uses reactive dyes; a natural dye collection is under development.

Hand-block printed cushion covers require specific care to maintain colour and print quality. Always cold wash (30°C maximum) — hot water loosens the dye-fibre bond and causes colour bleeding, particularly in deep tones like indigo and madder. Wash dark or saturated colour prints separately for the first 3 washes. Use a mild pH-neutral detergent — avoid biological detergents (enzyme-based) that strip dye. Do not use chlorine bleach on natural- or reactive-dye prints. Dry in indirect shade — direct Indian sunlight causes accelerated fading, particularly in the yellow and green components of multi-colour prints. Iron at medium heat (cotton setting, 160–180°C) while slightly damp for best results. SOISU block-print covers are pre-washed before sale; the colour on delivery is the stable post-wash colour.
