A garment measuring device comprises a standard body resembling a human body and a plurality of contact pieces of curved planes provided with a sensor for detecting the contact pressure exerted by the garment and protrusibly disposed at necessary positions of the standard body. With this device, measurement of a given garment is effected by putting the garment on the standard body, allowing the contact pieces to protrude from the standard body until they reach the garment, and calculating the sizes of the garment on the basis of the amounts of protrusion of the contact pieces.

Garment measuring device

A novel method of preparing a recipe for the reproduction of a particular color on a coloring material from a number of coloring agents or dyes, which comprises passing white light rays through a number of optical filtering means, controlling filtration characteristics of the filtering means to correspond to spectral distribution characteristics of the dyes, projecting on the coloring material the light rays which have passed through the filtering means to produce a monitoring color thereon, and modulating wavelength and amplitude outputs of the filtering means until the monitoring color simulates the particular color. The method precludes the complicated task of evaluating color affecting factors such as surface texture of the coloring material and eliminates the need for repeated coloring tests.

Optical color mixing method

In a method of preparing color separation printing patterns from a multi-color original design, the design is irradiated by light and multi-color light components reflected from minute picture elements constituting the design are detected. The detected light components are converted to picture element data representative of the optical energy level of the reflected light corresponding to each picture element. The picture element data are stored and filtered to form quantized picture element data indicative of several series of reflected light components respectively falling within different preselected ranges of color. This is done by comparing successive picture element data to detect significant differences in energy level indicative of color changes. The reason for each substantial difference in output level is determined, e.g., pattern defect or imperfection, and the filtered picture element data are stored along with change codes indicative of the reason for the difference. The color of the filtered picture element data is identified by comparison with predetermined stored sample color data. The picture element data are then modified in accordance with the change codes to comply with particular printing conditions or to correct the determined imperfections or defects arising in the original design before the data are supplied to a photomodulator which modulates a laser beam impinging on a photosensitive film for black-and-white reproduction of a predetermined identified color of the original design.

Method for preparing color separation printing patterns

The colors of individual picture elements in a fabric pattern design are encoded by comparing the level of transmittance or reflectance of the picture element at preselected wavelengths with stored values representing a reference color to generate a multibit code indicative of the color of the picture element. A comparator used for this purpose incorporates an error either proportional to the wavelength or of constant value so that the output of the comparator will indicate identity with the stored value if the input value for the picture element is within a certain range of the stored value.
