Most of the fabrics, both natural and synthetic, are not ready to receive and retain the colorants properly, especially when the item of clothing or the finished product must then be worn or has to find a practical use in home decoration. Applying a specific pre-treatment for each individual ink chemistry is the pre-condition for optimal printing performance, ensuring optimum fastness and brighter colours. The post-treatment of a fabric may also include the further application of post-printing functional fluids, such as anti-mold and sealing treatments.
