The method as claimed in claim 1 ,wherein identifying the at least one fibre in the digital image by employing at least one marker comprises identifying an unnatural colour profile within the at least one fibre and/or a characteristic shade on the at least one fibre in the digital image.3. The method as claimed in claim 1 , ...

Method and device for providing ingredient data for a prosthesis

A method is provided for providing a set of ingredients for manufacturing of a dental prosthesis covering. The method comprises receiving a background colour value providing information on a colour of a background substrate on which the prosthesis is to be provided, receiving an appearance colour value providing information on an appearance colour of the prosthesis and receiving a thickness value providing information on a thickness of the dental prosthesis covering. In an electronic memory, a first ingredient record is looked up comprising first ingredient value, based on the measured background value and the measured appearance colour value. The first ingredient values are adjusted in an electronic processor adjusted based on the thickness value and through electronic output means, the adjusted ingredient data is provided. By adjusting ingredients for thickness, a more natural appearance may be achieved.

COLOR CONVERSION PROCESSING APPARATUS, COLOR CONVERSION PROCESSING METHOD, AND NON-TRANSITORY STORAGE MEDIUM

A color conversion processing apparatus acquires spot color information, which is capable of defining a spot color with device-dependent color values. The color conversion processing apparatus further acquires a reference profile and an updated profile, and using the spot color information, converts an image signal of a spot color plate into a first image signal of a process color plate. Then, by having the reference profile and the updated profile act successively thereon, the color conversion processing apparatus converts the first image signal into a second image signal of a process color plate. 1. A color conversion processing apparatus for converting input image signals , which include image signals of process color plates and an image signal of a spot color plate , into output image signals of process color plates , comprising:a spot color information acquirer configured to acquire spot color information, which is capable of defining a spot color with device-dependent color values;a profile acquirer configured to acquire a reference profile representing a device link profile at a reference time at which the spot color is defined, and an updated profile, which is defined by the reference profile updated after the reference time;a first color converter configured to convert the image signal of the spot color plate into a first image signal of a process color plate, using the spot color information acquired by the spot color information acquirer; anda second color converter configured to convert the first image signal, which has been converted by the first color converter, into a second image signal of a process color plate, by having the reference profile and the updated profile, which are acquired by the profile acquirer, act successively thereon.2. The color conversion processing apparatus according to claim 1 , further comprising:a process color converter configured to convert the image signals of the process color plates into third image signals of process ...
