How Hand Block-Print Fabric Is Made, Step by Step
Hand block printing is a slow process, and that slowness is built into the cloth. Each colour requires its own carved block and its own pass across the fabric. A piece with three colours gets stamped three times, every repeat aligned by eye. Understanding the steps makes it easier to see what you are actually holding when you pick up a block-printed textile, and why the price of genuine hand-block cloth reflects real labour.
Step 1: Carving the Block
Every hand-block-printed pattern starts with a carved wooden block. In Sanganer, these are typically made from teak or sheesham wood, both hard and stable enough to hold fine detail over thousands of impressions. The wood is seasoned for months before carving to prevent warping.
A master block-carver traces the design onto the wood surface, then uses small steel chisels to cut away the negative space, leaving the pattern as a raised surface. Fine florals and intricate line work require chisels as narrow as a few millimetres. A detailed block can take two to four days to carve. Simpler, bolder designs take less time.
For patterns with very fine lines, the raised surface is sometimes faced with a thin layer of felt or foam, which helps the block pick up dye evenly and deposit it cleanly without bleeding.
A single pattern usually requires multiple blocks, one for each colour in the design. A printer working with a three-colour pattern might use three separate blocks, each carved to align precisely with the others.
Step 2: Preparing the Cloth
The cloth, usually unbleached or lightly bleached cotton, goes through several preparation steps before any printing begins.
First, it is washed to remove sizing (the starch applied during weaving) and any surface oils. Then it may be treated with a mordant, a chemical that helps the dye bond permanently to the fibre. In traditional natural-dye printing, mordanting is essential. Alum is the most common mordant for vegetable dyes, giving the cloth an ability to fix reds and pinks. Iron mordant gives greens and blacks.
After mordanting, the cloth is dried and stretched flat on the printing table. The table is long, usually several metres, padded with layers of jute and cloth to give a slight give underfoot for the block. A taut, even surface is essential for consistent stamping.
Step 3: Mixing the Colour
The dye paste is mixed to a thick, even consistency. In Sanganer, both natural and synthetic dyes are used depending on the workshop and the product. Natural dyes from sources like indigo, madder, pomegranate rind, and iron require more preparation but produce colours with a distinctive depth that synthetic dyes do not fully replicate.
The mixed colour is spread onto a flat tray lined with felt or thick cloth. The printer presses the block face onto this tray before each stamp to load the colour evenly across the raised surface.
Step 4: Printing
The printer stands at one end of the table and begins stamping. The block is loaded with colour, placed on the cloth at the starting point, and pressed down firmly and evenly with both hands or a rubber mallet. The block is lifted cleanly, without sliding, to avoid smearing.
Each impression is positioned using the small pin marks left at the corner of the previous stamp. These registration marks, applied with a thin metal pin set into the block edge, allow the printer to align the repeat consistently without mechanical guides. It is a skill built over years, and the slight variations in alignment from one impression to the next are what distinguish hand-block print from machine printing.
When the first colour is complete across the full length of cloth, the cloth is dried. Then the second block and second colour are applied in the same way, aligned with the first. A three-colour piece goes through this process three times.
Step 5: Fixing and Washing
After all colours are printed and dried, the cloth goes through a fixing step. Depending on the dye type, this is either steaming (for reactive dyes) or a chemical fix bath (for vat dyes like indigo) or prolonged sun exposure (for some natural dyes). Fixing bonds the dye permanently to the fibre so that the colour does not wash out in normal use.
The fixed cloth is then washed thoroughly in water to remove excess dye and any remaining mordant. This washing step is why Sanganer's location on the Sahibi River was historically important: soft river water produces cleaner, brighter colours than hard water.
After washing, the cloth is stretched and hung to dry, usually outdoors over bamboo frames or spread on grass. Drying in full sun is part of the process for some natural-dye prints, as UV exposure continues to develop certain colours.
Step 6: Finishing
Dried cloth is inspected for missed areas, smears, or registration errors. Minor imperfections from the printing process are expected and are not the same as defects. Then the cloth is cut, if it will be made into a finished product, or rolled and folded for sale as fabric.
In workshops that produce quilts, this is where the cloth goes to the quilting step: cut panels are layered with filling cotton and backing cloth, then sent for kantha hand-stitching to bind the layers.
What Small-Batch Reality Means
An experienced printer can stamp roughly 8 to 12 metres of cloth per day on a single-colour run. A three-colour pattern takes three times as long. This is not a process that scales the way machine printing does. Small workshops in Sanganer produce limited runs of each pattern, which is why you will often see hand-block-printed textiles described as small-batch or limited. That is accurate, not marketing language.
Kari by Kriti's Process
Every Kari by Kriti textile goes through this same process in Sanganer, from block-carved pattern to mordanted cloth to stamped, fixed, and washed fabric. The quilts collection adds kantha hand-stitching after printing, done by women artisans through a Hyderabad NGO. The curtains collection shows the printed cloth in a finished panel, where the repeat and the slight variation of hand work are most visible in natural light.
