COLOURS & DYES
We primarily use three kinds of colour processes; Pigments, Indigo Sol and Rapid colours.
Pigment dyes are very similar to paint. They need to be mixed with a synthetic binder before using, since these are polymer dyes. The true colour can be seen while printing unlike Sol & Rapid. The printed fabric is then heated in a chamber to make the print colour fast to rubbing, washing and sunlight.
Indigo Sol is derived from an Indigo dye formula are also called Soluble Vat dyes, thats why the term Indigo Sol. These dyes are mixed with an arabic gum before use. This dye does not show its true colour while printing. The printed fabric is then processed in a mild acid bath which helps in fastening the colour.
Rapid dyes are direct dyes which can be mixed with Indigo Sol to achieve desired shades of colour since Indigo Sol dyes are limited in their colour range.
