摘要:
This invention provides a method for forming a catalyst layer for carbon nanostructure growth, which can eliminate the influence of water in a liquid for catalyst layer formation, can grow homogeneous and highly oriented carbon nanostructures over the whole area of a substrate and can realize mass production of the carbon nanostructures, and a liquid for catalyst layer formation for use in the method, and a process for producing carbon nanostructures using the catalyst layer formed by the method. The catalyst layer for use in the production of CNTs is formed by preparing a catalyst metal salt solution of a catalyst metal-containing metal compound (a catalyst metal salt) dispersed or dissolved in a solvent having an ample wettability towards the substrate and coating the catalyst metal salt solution onto the substrate to a form a thin film. The thin film is then heat treated to form a catalyst layer. The substrate with the dried catalyst layer formed thereon is introduced into a carbon nanostructure synthetic device, and CNTs are grown by a thermal CVD method.

A printing unit prints an image based on print data. The printing unit has characteristics. An input-color-data storing portion stores input color data indicative of colors of inputted image data. The input color data have color component values of a first color group. A print-data generating portion converts the color component values of the first color group stored in the input-color-data storing portion into color component values of a second color group, thereby generating pre-correction print data having a predetermined bit width. A correcting portion converts the pre-correction print data into post-correction print data that is adapted to the characteristics of the printing unit. The correcting portion includes a bit-width correcting portion that generates the post-correction print data having a bit width greater than the predetermined bit width. The bit-width correcting portion selectively increases the bit width based on predetermined criteria.

An image processing apparatus for color image information inputs a combination of component values of reference colors that constitute a processing color, and converts the combination of component values into a lightness value, saturation value, and hue value. The first correction factor, the second correction factor, and the third correction factor each has a value of 1.0 for a lightness value, saturation value and hue value converted from a specified color respectively, and monotonically decreases toward 0.0. The modulation amount storage means stores a modulation amount of the lightness value, saturation value, and hue value respectively.The lightness correction means computes a corrected lightness value from the converted lightness value, the saturation correction means computes a corrected saturation value from the converted saturation value, and the hue correction means computes a corrected hue value from the converted hue value by using the first, second, and third correction factors, and the modulation amount. The inverse conversion means inversely converts the corrected lightness value, corrected saturation value, and corrected hue value into a combination of component values of reference colors.
