    Abstract: The invention of the Visual Comparator System herein disclosed consists of two axially transparent and/or translucent samples, one of which is usually a reference sample and one a test sample, a sample holder to hold the samples in axial alignment, and a comparator card with a surface colored and/or shaded in a pattern dictated by the comparison being made. The comparator card is moveably held or mounted in such a way that light reflected from separate portions of its surface pass through the two samples to the operator''s eye allowing a comparison based on color and/or optical density to be made.

    Abstract translation: 本文公开的视觉比较器系统的发明由两个轴向透明和/或半透明的样品组成，其中一个通常是参考样品，一个是测试样品，用于保持样品轴向对准的样品架，以及具有 通过进行比较而指定的图案中着色和/或着色的表面。 比较卡被可移动地保持或安装，使得从其表面的分离部分反射的光通过两个样品到达操作者的眼睛，允许基于颜色和/或光密度进行比较。

    Abstract: A color comparator providing, in a single device, an expedient and accurate combination of filter media arranged in a generally planar relationship to provide a three dimensional effect portraying the interrelationship of the filter media. The comparator includes neutral density material for providing substantially uniform white light transmission over the entire comparator area and means to facilitate assembly.

    Abstract: A method and apparatus for formulating an ink capable of reproducing a desired color having an unknown ink formulation. The apparatus includes a viewing area adapted to receive a color sample having a known ink formulation as well as a sample of the color having an unknown ink formulation. A number of filters are mounted above the viewing area such that any number or combination of the filters may be selectively positioned to overlie the known color sample until the unknown color is approximately duplicated by the known color sample and superimposed filters. The color of each filter is reproducible by a known ink formulation, and thus an ink capable of reproducing the unknown color may be prepared by mixing an appropriate amount of the inks indicated by the selected filters with the ink of the known sample.

    Abstract translation: 一种用于配制能够再现具有未知墨水配方的所需颜色的墨的方法和装置。 该装置包括适于接收具有已知油墨配方的颜色样品以及具有未知墨水配方的颜色样品的观察区域。 许多过滤器安装在观察区域上方，使得任何数量或组合的滤光器可以选择性地定位成覆盖已知颜色样品，直到未知颜色被已知颜色样本和叠加的滤光片近似重复。 每个过滤器的颜色可以通过已知的油墨配方重现，因此能够再现未知颜色的油墨可以通过将所选择的过滤器所指示的适量的油墨与已知样品的油墨混合来制备。
