Pattern and Print.

Textile printing is the process of applying colour to fabric to definite patterns or designs. In properly printed fabrics the colour is bonded with the fibre, so as to resist washing and friction. Textile printing is related to dyeing but, whereas in dyeing proper the whole fabric is uniformly covered with one colour, in printing one or more colours are applied to it in certain parts only, and in sharply defined patterns.
In printing wooden blocks, stencils, engraved plates, rollers or silk screens can be used to place colours on the fabric. Colorants used in printing contain dyes thickened to prevent colour from spreading by capillary attraction beyond the limits of the pattern or design
Traditional textile printing techniques may be broadly categorised into four styles:
- Direct printing, in which colorants contains dyes, thickeners and the mordants or substances necessary for fixing the colour on the cloth are printed in the desired pattern.
- The printing of a mordant in the desired pattern prior to dyeing cloth; the colour adheres only where the mordant was printed.
- Resist dyeing, in which a wax or other substance is printed onto fabric which is subsequently dyed. The waxed areas do not accept the dye, leaving uncoloured patterns against a coloured ground.
- Discharge printing, in which a bleaching agent is printed onto previously dyed fabrics to remove some or all of the colour.

Resist and discharge techniques were particularly fashionable in the 19th century, as we're combination techniques in which indigo resist was used to create blue backgrounds prior to block-printing of other colours. Most modern industrialised printing uses direct printing techniques.
