ABSTRACT

For high quality DTP products, it is important to optimize the parameters of media, pre- and after-treatment, ink,printer, etc. This study investigated the effect of types of fabrics(media) as a DTP parameters. Especially, the effects of media properties such as yarn twist and knitted fabric structure, on printability and color difference were examined. Two types of cotton yarn twist(830 and 1630 twist/meter) and five knitted structures of media were prepared with a single circular knitting machine. The K/S values of hard-twist samples were higher than those of normal-twist samples in every media structures. It is more effective to use the knitted fabrics of a hard-twist yarn to obtain dark color in the printing above input level value 60 where the printability improvement was most pronounced in case of plain structure. Among the five media structures a plain structure was the highest and that of corduroy was the lowest in terms of K/S values. Also ΔE values and lightness of the hard-twist yarn samples were smaller than that of normal-twist yarn samples when ΔE values were tested by using a standard of a normal twist yarn sample with a plain structure, which was increased in the case of corduroy structure.
