High-quality colour reproduction on silk textile was achieved from digital colour images by a precise colour-matching technique between original images on the monitor display and woven fabrics. More than a thousand various colours have been reproduced correctly with the use of only eight kinds of dyed wefts. Silk fabrics with a complex colour pattern in a width of 50 cm and a height of 75cm can be woven by an electronic Jacquard loom in just a few hours. The method of the colour reproduction on the silk textile bears a certain resemblance to ordinary painting. First, we prepare a 'colour textile block' database, that is, a kind of colour lookup table which plays the role of the palette in painting. A colour textile block is a woven silk sample textile of small size that shows various colours on a silk textile by a combination of textile structures and a few selected colour wefts among eight wefts. Colour attributes such as brightness, hue and chroma in the uniform colour space (CIEL*a*b*) of the colour textile blocks are measured by a colorimeter and stored in the colour textile block database. Second, we convert the pixels of original digital colour images into colour data of colour textile blocks, so as to minimise the colour differences between the colour attributes of the pixels in the original digital colour images and those of the colour textile blocks corresponding to the pixels. Third, on the monitor display we simulate the colour attributes of the textile to be woven from the assembled sets of colour textile blocks. Finally, we can produce fabrics on which the original colour digital image is reproduced in a manner resembling a colour photo. The estimation of the quality for the woven fabrics was carried out by several methods that exploit a colorimeter, a flatbed scanner and/or a digital still camera.
