Abstract:
A test sample color comparison device is disclosed which has a casing unit with an insertion slot for inserting a color test sample therein, and a display section for displaying the color test sample adjacent at least one of a plurality of reference color shades, as the reference color shades are successively moved into position adjacent the color test sample by a manipulation wheel. When an operator determines that a reference color shade adjacent the test sample corresponds in color to the color of the test sample, he pushes a switch to cause a readout of stored information corresponding to the reference color shade then adjacent the test sample. Readout of the stored information is based on a bit pattern set by a plurality of converter switches which are turned on and off in different patterns which correspond to the different color shades as the reference color shades are moved into position by the manipulation wheel. An uneven pattern code section moves in association with the manipulatable wheel and actuates the converter switches. A preferred uneven pattern code section is arranged so that all of the converter switches are actuated roughly equally during a full rotation of the manipulatable wheel, and so that only one of the converter switches is switched on or off during incremental movement of the manipulable wheel.
Abstract:
A color grading scale comprises a plurality of individual cast resin chips, each representative of a single color, with the chips attached one to another to form continuous array of color chips. In a preferred form, the chips are incorporated into a linear slide which fits within a groove formed in a surface of a frame. The frame is formed of a plastic material having a bright white color for maximum white light reflection. Formed in the frame adjacent to and spaced from the groove is at least one shallow pocket having a depth substantially the same as the groove for receiving a gemstone to be color graded by comparison to the color chips of the slide. Plural pockets of different sizes may be provided to accommodate different size stones.
Abstract:
Colored yarn poms are color coded according to a six digit coding and are arranged in a particular manner to enable color selection for carpets to be performed by designers, architects and the like without actually examining a sample carpet or a portion of carpet. The color poms are arranged in groups of which one pom defines the base color, and the remaining poms in that group are shaded poms, tint poms and tone poms. The triangular layout provides that the base color bunch is at the apex of a right angled triangle with the shades extending down one of the smaller sides of the triangle and the tints extending down the other side with the tones lying between the shades and the tints. The triangle is an isosceles triangle. Each pom preferably comprises a plurality of appropriately colored yarns held by a sleeve so that the yarn ends spread mushroom fashion from one end of the sleeve and a second sleeve can be slid over the first sleeve to compress the spread ends into a flat surface which can be presented to a spectrophotometer for identifying the color density in the said flat face.
Abstract:
A hue compass has triplet numerical values assigned to colors so that every possible color is identified with a unique triplet color identification number which represents the percentages of each primary color component present. Triplet values 100/0/0, 0/100/0, and 0/0/100 can be assigned to additive primaries blue-violet, green, and red, respectively. Their complementary colors yellow, magenta, and cyan can be assigned triplets 0/100/100, 100/0/100, and 100/100/0. Likewise, triplet values 100/0/0, 0/100/0 and 0/0/100 can be assigned to subtractive primaries yellow, magenta, and cyan, respectively. Their complementary colors, blueviolet, green, and red can be assigned 0/100/100, 100/0/100, and 100/100/0. A color robot can be employed to assign a triplet value for a given colored test object, whose color can be matched, e.g. by blending appropriate amounts of respective primary color pigments or dyes whose triplet color identification numbers are known.
Abstract:
A colorimeter comprises a case, a liquid crystal display (LCD) mounted on the case, a color chart provided on the case to permit holding of a specimen to be compared in close proximity to the color chart, and switches for indicating which color on the color chart the color of the specimen most closely approximates. Each switch is located adjacent a color on the color chart, and the states of the switches drive the LCD to display a reading corresponding to the color on the color chart which most closely approximates the color of the specimen.
Abstract:
A process for forming paint panel color standards in which a multiplicity of panels are painted and marked with a man/machine readable ID number; the improvement used with this process is as follows:(1) electronically determining the ID number of each panel and measuring each panel color coordinate values and feeding this information to a computer which establishes a criteria for various panel quality standards;(2) sorting the panels by electronically determining panel ID number and feeding the number to the computer which signals a robot to place the panel with a group of panels having the same quality standard.
Abstract:
A display rack and color selector assembly adapted to present to a homeowner a group of sample boards carrying actual roof shingles in a variety of colors and to afford a visual picture of a typical home whose architectural style is similar to that of the homeowner, the roof of the pictured home being selectively covered by a shingled surface in any one of the sample colors. The color selector includes a front panel on whose face is a radial array of pictures of typical homes in different architectural style, the roof in each picture being notched out to define a window whose geometry matches that of the roof. Mounted behind the panel is a rotatable color wheel which is divided into segments each having a shingled surface whose color corresponds to that of a respective sample in the group. The homeowner, while inspecting a pictured home on the panel face which is similar in style to that of his own, can then turn the color wheel to dial the segments thereof into registration with the roof window and thereby see how the pictured home looks when its roof is covered with shingles in any one of the sample colors. In this way the homeowner can decide which of these colored shingles is suitable to replace the worn shingles on the roof of his home.
Abstract:
A reflected color simulator is disclosed which utilizes a plurality of color discs positioned adjacent to one another wherein each disc includes several individual sections which are interleaved with respect to the other color discs such that rotational movement of the discs with respect to one another will vary the percentage of color from each disc which contributes to the color displayed when the discs are spun together. The entire group of discs, which could be of any number but preferably 6 or 7, are rotated by a main drive device to mix the colors so exposed to form the desired color by reflected simulation. An observer when viewing the spinning group of color discs will see a reflected color which is determined by the exposed percentages of each color disc. Each of the color discs preferably is of a different color and individual control of rotation of each disc is achieved in a remote fashion in order to allow independent rotation of the discs even during simultaneous rotation of all the discs to simulate the reflected colors. This remote control is achieved by including a plurality of drums oriented concentrically about the main drive shaft wherein each drum is fixedly secured at the forward end to one of the color discs such that rotation of one of the drums causes a relative rotation of one of the color discs with respect to the others.
Abstract:
A color control system for color separation, developing and printing fields including a plurality of strips of film with each strip containing color information and combining to form a color proof. A proof can be analyzed by eye or compared with a control wedge with conforming color information. The proof includes grey balance material visible from highlight through shadow to render grey when all colors are trapping correctly and show color differences on the proof when the colors are not trapping correctly. Color change indicators are on the proof to indicate unacceptable two color combination or an excess of a percentage of a contaminating color in a three color arrangement. Slur controls are on the proof to determine color slurring and permit the analysis of the percentage of color slurring when the proof is compared with later proofs or a control wedge. Highlight and shadow dots are provided to be viewed at chosen times to assure that the dots remain equal to each other with respect to each color in highlight and shadow at all times. Thus the color characteristics and color changes can be monitored at all times to enable the operator to make appropriate mechanical adjustments so that color control is maintained at a high quality level. Also, solid color patches of various colors can be provided to permit direct densitometer readings for comparison with recommended readings as a further color analysis check.
