The prior art of the primary color printing color control comparison is to use the image on the product as a direct comparison between the sample and the printed image, but the image interpretation is a full color gamut. The result is that there is no original specification of the original color. Value, without systematic ordering, the controller can only directly compare the content chromatic aberration of each image, relying on subjective evaluation to increase or decrease the primary color value of each ink zone, there is no uniform way to determine the color value correction of each ink key zone. Program.

Some people in the printing color management tool use solid color blocks to become functional color blocks, which are printed on the product as test targets, which can be used for visual comparison, but each function single primary color block is independently set, and the primary colors are cyclically sorted, and the primary colors are There is no related communication between the color block and the same color block of another cycle, then each independent color block is a fixed distance segment setting, so the visual comparison is not technically supported and cannot be implemented.

The invention provides a method for using a printing color and latitude visual inspection system device, the steps are as follows: printing the monitoring color strip of the system on a printed product, and using the electronic image data (software) to print the color value of each color Reflected in the image information function area of the monitoring color strip in the form of an image, The main body of the placement system device and the functional areas on the monitoring color strip correspond to each other, and the image tones are simultaneously exposed through the control holes on the main body, and each functional area can be visually compared with the color patches.

Using the neutral gray color area of the system body, the gray color shift state of each color block is detected, and the system main body is overlaid on the monitoring color bar, and the "point-to-point" type matching contrasts the neutral gray block.

Use each of the primary colors and black solid color patches to find out if the hue and gamut of each detection area change.

Using the primary color and the black intermediate halftone color block, the color value increase result transferred to the carrier after the pressure printing of the dot printing is detected, and the physical production state of the mechanical and the carrier are monitored.

The invention uses the gray balance technology to synthesize the production information of each primary color value, and the image surfacing result becomes the monitoring target, and the real-time production state can be continuously provided during the printing construction, so that the device can make an effective real-time, fast, point-to-point direct visual comparison. To set the color value correction scheme, it can also provide mechanical physical information to understand the physical changes of production. More innovative is that the color monitoring visual information area on the hardware of the same device body is designed to visually compare the upper and lower limits, which can effectively provide the tone latitude information directly, and the control operation is often operated in the narrowest error rate production environment. The external hardware of the main unit of the device plus the supporting color control strip is a complete continuous production system and device. It is the ultimate goal of standardized production using visually intuitive methods.

CIE L* a* b* color 3D metric unit is the amount of visually visible color of the data metric. The data "scale" is a combination of 3D coordinates. L* is the standard brightness, L*=0 is black and 100 is white; a*, b* is deductive color data, +a* stands for red zone gamut and -a* stands for green; +b* stands for To yellow and -b* represent blue. The hue "message" described in the present invention is the L* a* b* data value referred to in the color space. Each primary color, black and neutral gray has its standard data of L* a* b*.

The main body of the system and the color of each of the color blocks of the present invention are extracted from the standardized database by the L* a* b* value, and the color image is stored as a standard data "message" in the printing process.

The invention adopts a multi-function device, an external hardware, cooperates with a dedicated image color control detection medium, and prepares standardized primary color specifications according to standardized data; and prepares a neutral gray balance gray value data specification according to the gray balance physical property, Graphical production of various primary, black and gray color matching platforms. The present invention also provides upper and lower latitude monitoring zones for the tone quality control standard to set the contrast specification patches for the darkest and lightest primary, black and gray gradations. This tolerance is the acceptable tolerance for quality tolerance in print standardization. The invention refers to the edge visual theory to visually match the reference method, and also designs the position of the control hole for performing the visual operation, and provides an effective point-to-point reference environment to the special monitoring color strip of the invention, and uses the image method as a matching contrast to realize fast real-time. Visual comparison of standardized quality color value control operations eliminates the need for training professionals to use measurement instruments, eliminates the need for metering instruments to delay color control and eliminates the possibility of instrument error in instrument reading.

The technical solution of the present invention is different from the prior art method, and has major technical breakthroughs and creativity: the main body of the device of the invention stores the standardized data into a functional area of the planar information, and the main body is a simplified gray-scale color balance area without segmentation. Sufficient primary color gradation, clear design, no repetition and simple visual inspection.

The main body of the device of the invention is external hardware, and is provided with standardized setting data, and is manufactured as a visual measuring device, which is used as a special design monitoring color control strip placed close to the present invention, and the points are matched and matched with each other, and the overall length of the operation can be selected. It can also be made into a retractable tape, which is easy to make a comparison, easy to carry and store.

The main body of the device of the invention is provided with a control hole, and the monitoring function area is independently compared with the cells to reduce visual confusion. The functional color gradations of the primary colors and blacks on the main body of the apparatus of the present invention can be made into the optional color block contrast color patches according to the selected national standardized data. The color gradation on the main body of the device can be replaced with a suitable solid color and halftone reference sample gradation for matching, or can be replaced when the gradation is aged or damaged.

The invention standardizes the color management data, and deduces the image design into data visualization, and forms the main body of the device, and outputs the numerical information of each functional component for visual matching.

The present invention is provided with a color quality management upper and lower latitude specification functional area.

The special design of the present invention monitors that each functional area on the color control strip is an overprinted image in which a series of geometric shapes are closely connected. If the contact position of each functional area fails to register the printing successfully, it can visually reveal overlapping or separate mechanical physical adjustment problems.

The present invention differs from the prior art color bars:

The main body of the device is externally set hardware, which sets and stores standardized color value data, and uses color images to interpret the primary colors, black and gray balance messages, and uses edge visual instinct to compare and visually visualize millisecond visual responses to provide matching. The function is used for monitoring the color strip matching for the special design of the present invention.

Provide visual and visual comparison information, without the need to use instrumentation to measure production results to obtain analytical data.

The main body of the device is designed with no segment and reduced gray value environment, and with the state of each primary color and black in production, deductively imaged, providing industrial standard color value results, which effectively reflects the product monitoring area. The color cast image, clear and accurate, provides accurate color value correction information. This hardware is mobile and reproducible for multiple comparisons.

This color visual comparison system has a qualifier specification image with upper and lower limits of quality control to become functional area information, visual color difference, and no need to use detection instruments.

The design of the invention is in line with the standardization of the printing industry:

Lithography is a mechanical printing technique. On the printing plate, the image is accurately separated into the distribution positions of the primary colors and the black dots. The appropriate pigment film is applied to the dots and transferred onto the carrier by a soft blanket. A full color image.

Industrial standard production, monitoring the color value and color gamut of the primary color state can obtain data from (100%) solid color gradation; monitoring dot gain rate is the use of halftone gradation and solid color gradation calculation results, the purpose is to verify materials and printing equipment Pressure physical state; Neutral gray balance can be used as an effective guide to analyze the average amount of ink after each primary color is overprinted.

The design of the present invention also fully considers that the quality control latitude is a key monitoring item in the continuous production process, and the upper and lower limit controllable operations are often operated in the production environment with the narrowest error rate to ensure the best quality of the product. result.

The gray balance formula technology is provided in the invention: the gray value of the neutral gray is a predetermined combination of the dot points in the gray balance production technology, and the dot is in the printing process, and the paint is applied by using the required dot size and quantity. The dots are the main primary colors cyan "C", magenta "M", yellow "Y" and the percentages suitable for the secondary colors, and accurately interpret each other into a neutral gray image.

The invention fully utilizes the operation theory of the gray balance color control system: The gray balance color control system is a relationship between the neutral gray and the black halftone including the balance of the primary color value. The combined information of the neutral gray is directly extracted from the construction image, and the quality control bar is monitored by performing the imaged detection area at the designated position. The use of the black hue is a non-color cast characteristic and the near neutral gray halftone color gradation produced by the desired primary color is closely arranged to reflect the gamut balance information of each primary color. The neutral gray color tone will be exposed to the lack of color or super color of a primary color by the black halftone without the color cast property. This is the "self-style" visual contrast method that can effectively practice neutral gray balance. Quality control production.

The main function image of the apparatus of the present invention and its use: The main body of the apparatus for visually measuring the color of the system needs to design a plurality of color plane information function areas to be "function images" as the main body of the apparatus. The industrial standardization data is interpreted in the form of images, as the main body of the device, for the special quality control monitoring color bar contrast printed on the product, reflecting the color tone change of the color pattern on the product. The external hardware design of the device is equipped with the color balance data of various primary colors of the industry color standard and the physical production status of the mechanical and carrier materials, and the continuous monitoring function of quality tolerance. The production and use of each functional area are as follows:

The neutral gray tone of the main body area of the device is the neutral gray color grading domain data extracted from the database of the primary color balance color value overprinting in the printing industry color standardization, and the neutral gray tone function area on the cost device , covering The area of the subject.

The primaries and black (100%) solid color independent gradation ribbons are used to provide standard ink gamut and density comparison information.

The halftone gradation ribbon for each of the primary and black independent halftones is an image tone that provides a standard dot gain rate. Mechanical and carrier physical change comparison functions are also available.

The upper and lower error rate functional areas of the quality control standard method are deep and light color steps, which are the reference parts of the quality control deviation tolerance. Neutral gray tone gray scale and black monochrome gray scale should be in deep and shallow specifications. The depth and lightness of the real and intermediate halftone values of each primary color should also be between the specifications of the error rate.

In the present invention, the monitoring color strip function image and its use: The function area of the monitoring color strip is produced according to the positioning of each functional element set on the main body of the device, and the sequence and interval are the same, and the functional areas are as follows:

The main body design of the device is based on the neutral gray balance technique, which sets the relationship between neutral gray and black halftone. The use of black tones is a non-color-shifting feature that is interlocked with the neutral gray halftones produced by the desired primary colors to reflect the color gamut balance messages. It is the ultimate goal to monitor the matching of the double ash on the color strip and to match the visual hue matching conditions. The neutral gray and black gray areas are geometrical coherence, close to the setting, juxtaposition and sorting, and also have the positioning registration function.

The primary color and black (100%) solid color independent color scale function area is used to provide standard ink color gamut comparison information and density measurement environment as the calculation network value-added rate.

The halftone gradation ribbon for each of the primary and black independent halftones is matched to the image tone by the contrast dot gain rate. It also provides visual inspection of mechanical and physical changes in the carrier. It is a dual function message effect.

The invention is composed of a hardware main body and a monitoring color strip, each of which has a standardized printing process standardization information, and is made into a functional area, which are respectively as follows:

Matching hardware body: The hardware body provides matching guidance purposes. The main body of the device records the production standard data of each primary color value in the standardization project, and replaces the "scale" reading with a visual color image. Each function provides a visual reference sample for comparison purposes. The upper and lower latitudes in the quality control project are also set to pass the allowable error specification in color images. It is a donation data operation and a standard data message transmission function.

Monitoring color bars: Using software to record the monitoring items required for standardized production, designed into electronic digital image files, which can be distributed to the production unit by digital Internet. The functional images in the digital archive are the items of the monitoring tone plane information required for standardized production. The color bar is equipped with the monitoring target of the color standard project, and the monitoring color bar is formed by image. The color attached to the image of the monitoring item is the same color component of each functional area on the device. Then the color strip is combined with the normal printing construction operation, and is imaged in the color strip monitoring area on the printed matter. The monitoring item functional area is a neutral gray area, and the primary colors and black (100%) solid colors and intermediate halftone areas. Monitoring color bars can directly reflect printed products Hue and gamut results to be monitored. Emphasis is placed on the physical state of production of the primary colors, blacks, machines and carriers, providing a comparison platform for matching hardware practices and performing point-to-point, edge-visual comparisons. The monitoring color strip is a special design, matching matching hardware, and the monitoring position of each functional area is matched with the sorting and spacing of the functional areas on the main body of the device, so as to achieve 100% point-to-point comparison accuracy. It is also possible to use cell-to-point comparisons, but the required comparison time is increased. This is the acceptance of the message operation, receiving the standard data message color value correction.

According to the main body of the device, the length design can refer to the monitoring width on the comparison operation, according to the production requirements of the primary colors in the printing industry standardization, and the contrast monitoring function image is produced, and the point-to-point matching device and the monitoring color strip are practiced. The color deviation message is a color value correction scheme.

The invention can also be made into a telescopic reel which is made of an external flexible rewindable material; the telescopic tape length design includes equal monitoring widths on the contrasting operation. The manufacturing method may be that a printing method is used to print each functional image on a rewindable carrier. The monitoring color strip surface is provided with a plurality of detection functional areas, and the memory visual color contrast information; according to the production of the primary colors in the printing industry standardization required to monitor the project, printed as a comparison device function image. The control hole in the main body of the device of the present invention can provide sufficient space to expose the monitoring target to the device for edge visual comparison, and the distribution plan according to the number of samples covers the entire device length. The method of using the device is to "point to point" The placement, overlying the test target, the control hole on the device reveals the test target. The gray scale and the primary color, the black solid color and the halftone color gradation on the device surround the detection target, and then start to detect the gray tone value, the gray domain of each monitoring function area by using the edge visual method and the cell form. The dot gain rate, the color value of each primary color, and the color gamut change, so that the color value correction project can be performed in real time. The inner side of the hole edge reveals the thickness of the material as the color of the material. When the matching hardware is placed on the comparison target for visual comparison, the contrast hole material color will visually affect the color discrimination error, so the hardware material may be the same color as the color block of the functional area, or may be processed to be the same color. The control hole is visually contrasted because of the thickness of the material, and is placed on the contrast target. The color of the functional area of the hardware surface and the monitoring target may have the thickness of the material, and the vertical inner side of the control hole may form a shadow on the target of the light projection. In order to make the visual color discrimination error in comparison, the inner side of the comparison hole of the present invention is designed as a slope type, and the upper aperture is wider than the lower aperture, and the elimination of the shadow improves the accuracy of the visual comparison.

The matching hardware color tone information of the apparatus body of the present invention is a comparison function area sample, and can provide a color tone and a dot gain rate specified by the comparison platform to the standard color of the printing color management standardization body to refer to the production sample.

According to the invention, the real color and the halftone color gradation of each primary color can be used to calculate the color gamut and the data required for the value-added measurement of the primary colors set by the industrial standards of different countries, and then the solid colors and intermediate colors of the primary colors on the main body of the device. Halftone gradations are used to match and match with industry standards. In the main body of the device of the present invention, the color block can use the micro-track of the device, the sliding slot or directly embedded in the main body of the device, and the functional areas can be taken out to replace the position; or the functional color gradation of the primary color set by another color management standardization can be replaced; In addition, due to the standard color aging and environmental damage of the functional color blocks, replacement is required to ensure that the hardware quality of the main body of the device is often operated under the optimal and stable contrast state.

The device of the present invention is provided with different printing carrier materials specified in color management to determine the required color value and color tone of each primary color and black, and becomes a functional color gradation accessory, which can be selected according to the selected construction. Replace the material to match the production.

The panel operation of the main body of the device can be manually and automatically placed:

Manual placement is performed at each inspection. The functional areas of the panel and the monitoring color strip require manual point-to-point placement. The control holes on the panel need to reveal the contrast monitoring functional area for visual comparison. When the test is completed, it needs to be taken away from the test target, cycled, or placed side by side for visual comparison.

The automatic placement is designed with automated placement equipment that uses pneumatic, electronic, and mechanical mixing devices to accurately position the matching hardware at the designated position of the monitor color strip for visual comparison. The device panel needs to be pre-aligned with each other in point-to-point alignment. The control holes on the panel need to reveal the same functional area on the contrasting color strip for visual comparison. During operation, use the button or auto sensor to activate the system to accurately place the device for color control operation, detect color value and color tone change, color cast, and make real-time correction if necessary; after the test is completed, the device can be automatically released and returned. Wait until the next standby command in the system standby position, and cycle.

The apparatus body and the replaceable color block of the present invention may be a hard material such as paper (board), metal, wood, plastic, glass, synthetic thick material, ceramics, etc.; or may be a soft rewindable material such as paper, Cloth, silk, plastic film, synthetic thin material, etc., and painted on the carrier by printing, painting, dyeing, primary color casting, electroplating and ceramics.

The invention also designs an independent latitude neutral gray, each primary color and black visual device, which will monitor the upper and lower limits of gray, primary colors and black color values, solid colors and intermediate halftone color blocks, and adopt printing, painting and dyeing. Construction of primary color casting, electroplating and ceramics is carried out on the carrier.

The monitoring color strip design is a series of geometric images that are placed in close series and are used to monitor the accurate overprint indication function.

Each image provides dual functional use. Each image is equipped with a monitoring item that acts as a detection function. Each function image can contain a tonal plane message and a geometric shape design, and the geometric shape is a mechanical physical contact result of the connected image, and the images are seamlessly arranged.

The functional images described above can respectively perform tone plane information and geometric design:

The color flat message content is that each function image has a set printing item, that is, the neutral gray of each primary color overprint, Solid colors and black halftone patches for each primary color and black.

The geometric shape is the result of the mechanophysical contact of the connected image, and the design focus is that there is no microscopic gap between the images.

The relationship between the hue and geometric design of each function and the method of use are as follows:

Monitoring tone results: According to the neutral gray balance technique, the neutral gray is produced by the primary colors and black overprints. The neutral and black gray images have the same color gamut and color gamut, plus seamless contact and accurate overprint results. The double-gray image is a "one-piece" gray level with no segmentation, which is the most perfect color value, color gamut and overprinting result. If the two gray-field color casts are inconsistent, then the gray-scale visual difference is closely followed, and it is obvious that the primary color needs to be corrected.

Monitoring mechanical physical contact results: The double-gray image is a seamless, close-fitting design with consistent visual gamut. Once a certain primary color or black is not accurately printed, although the visual color tone of the functional color tone plane information is consistent, the functional geometric image and the close-fitting image are physically deviated from the edge contact position, and the contact positions may overlap. It can also be separated by contacts. The overlap is that the number of dots added to the interface at the interface position is dark, depending on the number of overlapping dots; the separation is that the contact positions are separated from each other, and there is a lack of separate color dots and obvious light color and color cast. It can also be a comprehensive separation process carrier. Color.

The overall monitoring color strip design, the same function image is equipped with double visual inspection results, without the use of a magnifying glass, while visually revealing the color tone and overprint production problems, other market color bars do not have visual monitoring overprinting function, and no same functional area is available. Design for dual practical use.

The invention is a contrasting instinct with creative use and raw oysters, visually matching the matching system, novelly designing the color image as a visual color image instead of the "scale" reading function area, and incorporating the tolerance of quality control. Degree specification technology, practical design of special monitoring color strips to match the quality control system of the present invention for continuous qualified tolerance production.

The present invention is also capable of effective forward-looking operation: The present invention is a forward-looking method for pre-determining standardized color values and overtone color data of each primary color determined by the printing industry as a reference for monitoring the color tone functional area. The printing process is constructed on the carrier material and co-produced with the special quality control monitoring color strip.
