[0002]

[Prior art]

 Conventional scanner bases are for simply attaching a document or pressing a document.

[0003]

[Problems to be solved by the invention]

 The conventional product has not been devised to improve the color (especially the highlight side), tone, and gradation of the original, nor has it been worked as a tool for managing the original. The present invention is mainly for reflection manuscripts (especially illustrations drawn on drawing paper etc. with paints, crayons, colored pencils, etc. or burnt photographs with many pale colors), but was made to solve this drawback. It is.

[0004]

[Means for solving the problem]

 A white frame 3 and a black frame 4 are provided on a transparent base (thickness is about 0.3 mm), and color patches 5a, 5b, 5c, 5d, 5e, 5f, and 5g (hereinafter referred to as color patches 5a) are provided on the right end thereof. , 5b, 5c, 5d, 5e, 5f, 5g), and gray scales 6a, 6b, 6c, 6d, 6e, 6f, 6g, 6h. 6i (hereinafter referred to as all gray scales 6a, 6b, 6c, 6d, 6e, 6f, 6g, 6h, 6i). Please refer to FIG. (Speaking from both sides, the square frame immediately inside both sides, which is the only one adjacent to the color patch and gray scale [just like a bread mimi remains], is a black frame, and the square frame inside it [this A white frame is the same as that of the bread loaf only, and the rectangle in the center is the transparent part.) The color patches shall be seven colors. 5a is Murasaki (cyan 50% magenta 50%), 5b is red Murasaki (cyan 30% magenta 90%), 5c is green (cyan 70% magenta 20% yellow 70%) 5d is chimaki (cyan 8% Yellow (40% yellow), 5e orange (70% magenta yellow 80%), 5f red (90% yellow magenta 100% cyan 20%), 5g colored navy (95% cyan 85% magenta 85%) I do. On the other hand, the gray scale has nine levels and is colored with one color of black only. 6a is set to 10%, 6b is set to 20%, 6c is set to 30%, 6d is set to 40%, 6e is set to 50%, 6f is set to 60%, 6g is set to 70%, 6h is set to 80%, and 6i is set to 90%. The coloring method shall be printing, and the printing surface shall be the surface. Only white frames use white spot colors, and surprisingly, process inks (cyan, magenta, yellow, black) are used. The white frame and the black frame are both solid (100%), and the black frame may be black. Note that the solid lines shown in the drawings are not printed at all. The present invention is a scanner base having the above configuration. By the way, the reason why the problem is solved can be explained as follows. The flatbed scanner sets the percentage of the highlight side (halftone dot%) and the percentage of the shadow side (halftone dot%) of the document only within the trimming determined by the operator as the set data (eg, “ink painting”). If necessary, read in accordance with the tone curve for "ink painting". Then, it is considered that the halftone dot% of the highlight and the shadow leads to an intermediate ratio (halftone dot%). For example, when scanning (disassembling) an illustration, it is common to trim the illustration itself and the surrounding white paper (whiteness of the paper). Or trim the entire paper. Then, scanning (decomposition) is performed. However, this presents a major problem. Because flat scanners determine highlights only within trimming, the whiteness of the paper with the lowest density (bright) is the highlight point, and the normal percentage is 0 to more than 3% at most. Only the halftone dot is attached. In other words, the part with the lowest density (bright) in the trimmed area is read as the highlight part and the highlight point (minimum point part). I do not specifically consider it. In fact, the next lower density (brighter) part (lighter color) is important. Therefore, if the pale color of the illustration must be represented by, for example, 2% magenta and 3% yellow, it is too often 0% magenta and 1% yellow. In short, there is a weak point in reading the highlight side, especially in pale colors. To solve this, I thought that a new highlight (point) could be provided. The white frame of the scanner base of the present invention is printed solid with white special color ink, but the density of the white frame is lower than the white density of the paper in the illustration. In other words, it is brighter than the white paper in the illustration. (This is not to say that the differences caused by the specialty or composition of the white spot color ink, but rather that the white printed on the polyester base and the paper white have different densities for the same white. Therefore, if the white frame of the scanner base of the present invention is inserted at the time of trimming, it becomes the minimum point (highlight point), and the white dot is the least dot, and the next is the illustration. The paper white of the illustration is not at least 0%, so the highlight side (light color) of the illustration always has a halftone dot. This prevents the so-called “jumping” of halftone dots. Thus, the pale colors of the illustrations are better represented. Second, the density of black in the black frame is higher than the black that can usually be represented by illustrations (black written with paint, crayons, colored pencils, etc.). Therefore, if a black frame can be inserted at the time of trimming, the scanner will not regard the black frame as the point on the shadow side, and the shadow side will be higher (darker) than when the black of the illustration is the point on the shadow side. ) Is set. As described above, if only white and black frames are inserted during scanning (disassembly), the density range (range) will be wider than when only illustrations including paper white are trimmed alone. If you look at the illustrations, the highlights, shadows, and the middle will have an increased density. If you want to examine the appearance of all colors and the appearance of individual colors, use color patches and gray scale. The color patch is used as follows. First, as a guide to see how different colors appear depending on the data (data set in the scanner such as “ink painting”, “photo”, and “print”). Second, for example, after scanning (decomposing) the first illustration, the image is imported to the computer, and only the green part is newly added (on the computer) using a method other than the tone curve. If you forget to save the data and you don't know how much it was upgraded, and you want to increase the density of other similar illustrations as well, this is a kind of indication. If the ratio of the green portion is 75% for cyan, 40% for magenta, and 80% for yellow after the increase in the density, the ratio may be increased from the next time. As for grayscale, as a first step, it is used as a guide to see how the overall appearance differs depending on the data (data that is set in the scanner such as "ink painting" or "prints"). Secondly, the image was imported into the computer and the overall density was increased. However, I forgot to save the data, and I couldn't understand how much it was increased, and wanted to increase the density of other similar illustrations as well. In this case, the concentration should be increased as a guide to the overall concentration, and the ratio should be adjusted from the next time.

[Embodiment of the invention]

 When disassembling a reflection original (illustration) using a flat scanner, first, the scanner base of the present invention is placed on a scanning table with the printing side down. Next, the reflection original (illustration) is placed on the scanner base of the present invention with the design side down. However, the picture part including the paper white of the illustration is arranged so that it fits well in the transparent part 2 (see FIG. 1) of the scanner base. And trimming, but white frame 3 and black frame 4, color patch and gray scale must be included in trimming. And scanning. The result is compared with the result obtained by trimming and scanning only the picture part including the paper white without inserting the white frame 3.

[0006]

【Example】

 (B) Prepare an illustration that contains many pale colors drawn on white paper such as drawing paper with paint or crayon or colored pencils, a flat scanner (connected to a computer), and a scanner base of the present invention. (B) Place the scanner base of the present invention on the scanning table of the flat scanner with the printed side down. Next, arrange the picture part of the prepared illustration (including the white part of the paper) so that it fits well into the transparent part 2 of the scanner base of the present invention. Trim white frame 3, black frame 4, color patches and gray scale. Scan. To compare with (c) and (b), this time trimming only the illustration, including the white part of the paper, without inserting white borders, black borders, color patches, and grayscale, and the same as (b) Scan with data (such as "ink painting", "photographs", "printed materials", etc., which are preset in the scanner) The results of (d) and (b) are compared with the result of (c). The data is changed (for example, the data is changed from “ink painting” to “photo”) by the scanning method (e) or (b). (Pay attention to the color patches and gray scales and see if they can be used as a guide to see the difference in color appearance.) (F) and (b) import the resulting images to a computer, Method of color patches described in “2. Import the images of the results of (g) and (b) into a computer, and perform it as described in Grayscale Usage Part 2 described in “Means for Solving the Problems”.

[0007]

[Effect of the invention]

 (A) In a reflection original, particularly in an illustration having a light color, it is possible to prevent the "jumping" of highlights (the absence of halftone dots) and increase the density. (B) The reflection density, especially in illustrations with light colors, can increase the shadow density. (C) By (a) and (b) above, the intermediate density can be easily increased. (D) Due to the presence of color patches and gray scales, it is easier to grasp the difference in the color appearance of each data based on the data (data set in advance in the scanner such as “ink painting”, “photo”, “print”) it can. (E) After scanning (decomposing) the reflection original (illustration), the image was input to a computer, and only the color gamut was increased (on the computer). Similarly, for the remaining reflection original (illustration), if you want to increase the density of only a certain color gamut (eg, the green part), if you focus on the green in the color patch, follow the same. Only a certain color gamut (green area) can be increased. (F) After scanning (decomposing) the reflection manuscript (illustration), the image was input to the computer, and the entire image was increased (on the computer), but the data was forgotten to be saved, and other similar remaining Similarly, if you want to increase the overall density of a reflection original (illustration), and if you pay attention to the existence of gray scale, you can increase the overall density of the same in the same way.
