Block printing is a form of dying and coloring a fabric using wooden blocks. India is one of the largest manufacturers and exporters of block printed fabric in the world. Block printing craftsmen use wooden or metal blocks to create beautiful designs; sometimes, blocks are also used.
Techniques of Block Printing in India
Direct Printing : In this technique, the cotton or silk cloth is first bleached. Then the fabric is dyed, unless a light background is desired. Thereafter, the fabric is printed using carved blocks, first the outline blocks, then the ones to fill color.
Resist Printing : In the resist technique, areas that are to be protected from the dye are covered with a mixture of clay and resin. The dyed fabric is then washed. The dye spreads into the protected areas through cracks, producing a rippled effect. Block prints are then used to create further designs.
Discharge Printing : In this technique, the fabric is dyed. Then, a chemical is used to remove the dye from the portions that are to have designs in a different color. These portions are then treated, so they may be re-colored. A Close Look at the Process of Block Printing in India
The fabric to be printed is first washed free of starch.
If tie-dyeing is required, this is done before the printing process. Incase fabric is dyed, it is washed thereafter, to remove excess color. It is dried in the sun.
The fabric is then stretched over the printing table and secured with pins.
Color is mixed separately and kept ready. So are the blocks. The blocks are made of teak wood and hand-carved. They are soaked in oil for 10-15 days to soften the timber.
The color is kept in a tray which rests on another tray that contains a liquid made of glue and pigment binder. This gives the color a soft base and permits even spreading of color on the block.
When printing begins, the color is first evened out in the tray. Then the block is dipped in the outline color.
The block is pressed down hard on the fabric, to make a clear impression. Thereafter, other blocks are used to fill in color.
Once the fabric is printed, it is dried in the sun. It is then rolled in newspaper to prevent the fabric layers from sticking to each other.
The fabric is then steamed.
Thereafter, it is washed in water and dried in the sun.
Ironing is the last stage.
