Resist printing, any of various methods of colouring cloth in a pattern by pretreating designed areas to resist penetration by the dye. To obtain a two-colour pattern on goods already dyed in one colour, a dye paste is applied in the desired design; the paste contains a substance resistant to a second dye, which is then applied to the cloth, developing colour only in the areas not covered by the paste. Batik and tie-dyeing are examples of resist printing. In stencil printing, the design parts not intended to take colour are covered with paper, woven fabric, or metal while the dye is passed over the surface.
In resist printing, the fabric is first printed in a design with a chemical that resists dye. The fabric is then dyed. The resist chemistry will leave the fabric white or a lighter version of the base color in the printed areas. One of the advantages of this method is that dyes with very high colorfastness can be used. Resist printing can be performed on cotton fabrics that will subsequently be dyed with reactive, vat or naphthol dyes. This combination of printing and dyeing is back to the ancient method of batik.
