Dye in the context of "Textile arts"

Batik is a dyeing technique using wax resist. The term is also used to describe patterned textiles created with that technique. Batik is made by drawing or stamping wax on a cloth to prevent colour absorption during the dyeing process. This creates a patterned negative when the wax is removed from the dyed cloth. Artisans may create intricate coloured patterns with multiple cycles of wax application and dyeing. Patterns and motifs vary widely even within countries. Some patterns hold symbolic significance and are used only in certain occasions, while others were created to satisfy market demand and fashion trends.

Resist dyeing using wax has been practised since ancient times, and it is attested in several world cultures, such as Egypt, southern China (especially among hilltribes like the Miao, Bouyei, and Gejia peoples), India, Indonesia, Malaysia, Nigeria, and Sri Lanka. The technique developed in Indonesia (especially in Java) is among the most sophisticated, although its antiquity is difficult to determine. It first became widely known outside of Southeast Asia when it was described in the 1817 History of Java, leading to significant collecting efforts and scholarly studies of the tradition and crafts. Javanese batik was subject to several innovations in the 19th to early-20th centuries, such as the use of stamp printing of wax to increase productivity. Many workshops and artisans are active today, creating a wide range of products and influencing other textile traditions and artists.

Ink is a gel, sol, or solution that contains at least one colorant, such as a dye or pigment, and is used to color a surface to produce an image, text, or design. Ink is used for drawing or writing with a pen, brush, reed pen, or quill. Thicker inks, in paste form, are used extensively in letterpress and lithographic printing.

Ink can be a complex medium, composed of solvents, pigments, dyes, resins, lubricants, solubilizers, surfactants, particulate matter, fluorescents, and other materials. The components of inks serve multiple purposes; the ink's carrier, colorants, and other additives affect the flow and thickness of the ink and its dry appearance.

A pigment is a chemical compound that gives a substance or organism color, or is used by humans to add or alter color or change visual appearance. Pigments are completely or nearly insoluble and chemically unreactive in water or another medium; in contrast, dyes are colored substances which are soluble or go into solution at some stage in their use. Dyes are often organic compounds whereas pigments are often inorganic. Pigments of prehistoric and historic value include ochre, charcoal, and lapis lazuli. Biological pigments are compounds produced by living organisms that provide coloration.

An airbrush is a small, air-operated tool that atomizes and sprays various media, most often paint, but also ink, dye, and make-up. Spray painting developed from the airbrush and is considered to employ a type of airbrush.

Screen printing is a printing technique where a mesh is used to transfer ink (or dye) onto a substrate, except in areas made impermeable to the ink by a blocking stencil. A blade or squeegee is moved across the screen in a "flood stroke" to fill the open mesh apertures with ink, and a reverse stroke then causes the screen to touch the substrate momentarily along a line of contact. This causes the ink to wet the substrate and be pulled out of the mesh apertures as the screen springs back after the blade has passed. One colour is printed at a time, so several screens can be used to produce a multi-coloured image or design.

Traditionally, silk was used in the process. Currently, synthetic threads are commonly used. The most popular mesh in general use is made of polyester. There are special-use mesh materials of nylon and stainless steel available to the screen-printer. There are also different types of mesh size which will determine the outcome and look of the finished design on the material.

Hand-colouring (or hand-coloring) refers to any method of manually adding colour to a monochrome photograph, generally either to heighten the realism of the image or for artistic purposes. Hand-colouring is also known as hand painting or overpainting.

Typically, watercolours, oils, crayons or pastels, and other paints or dyes are applied to the image surface using brushes, fingers, cotton swabs or airbrushes. Hand-coloured photographs were most popular in the mid- to late-19th century before the invention of colour photography, and some firms specialized in producing hand-coloured photographs.

A colourant/colour additive (British spelling) or colorant/color additive (American spelling) is a substance that is added or applied in order to change the colour of a material or surface. Colourants can be used for many purposes including printing, painting, and for colouring many types of materials such as foods and plastics. Colourants work by absorbing varying amounts of light at different wavelengths (or frequencies) of its spectrum, transmitting (if translucent) or reflecting the remaining light in straight lines or scattered.

Most colourants can be classified as dyes or pigments, or containing some combination of these. Typical dyes are formulated as solutions, while pigments are made up of solid particles suspended and are generally suspended in a vehicle (e.g., linseed oil). The colour a colourant imparts to a substance is mediated by other ingredients it is mixed with such as binders and fillers are added, for example in paints and inks. In addition, some colourants impart colour through reactions with other substances.
