Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a print density sample sheet and a sample book used for trying out and viewing print density.

[0002]

[Prior art]

 In letterpress printing and offset printing, a large number of dots are arranged vertically and horizontally to represent characters and figures. The size of these dots corresponds to the density of printing, and the dots are large in the dark areas and small in the light areas. Therefore, if the dot size is made clear, the print density will be determined.

In order to determine the density of this printing, conventionally, a craftsman skilled in printing has been used to obtain a desired density while performing proof printing and test printing.

[0004]

[Problems to be solved by the device]

 However, not only relying on a professional craftsman, even if you are an amateur, if you can specify the dot size that corresponds to the density of printing, it will be easier to perform the final printing and the desired color may be expressed. Will also be higher.

On the other hand, although various color charts showing changes in color and changes in density are provided, these color charts only show changes in density for a limited number of colors. , Does not correspond to various colors. Also, it is impractical to create a color chart every time a new color is used.

Therefore, an object of the present invention is to provide a print density sample sheet and a sample book that anyone can easily try and see the print density of various colors.

[0007]

Means for Solving the Problems In order to solve the above problems, a printed density sample sheet according to claim 1 of the utility model registration claim has a plurality of light-transmitting dots mixed in an opaque region. , These dots are regularly arranged in the opaque area according to their size.

Further, the print density sample book according to claim 2 of the scope of utility model registration claims includes the print density sample sheet according to claim 1 and a plurality of colored sheets colored in mutually different colors. It is provided with a piece and a holding means for detachably holding these colored pieces.

[0009]

[Action]

 The print density sample sheet according to claim 1 has a plurality of light-transmitting dots mixed in an opaque region. By overlaying this sample sheet on the solid color, you can see this color through each dot. Since these dots are regularly arranged according to their respective sizes, the density when the dots are made larger and the density when the dots are made smaller can be identified.

Further, according to the print density sample book of the second aspect, the holding means detachably holds a plurality of colored pieces colored in mutually different colors. If you select one of these colored strips and overlay the selected colored strip on the print density sample sheet, you can see the density when the dot is enlarged or the dot is reduced for this color. The concentration of can be identified.

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows an embodiment of a print density sample sheet according to the present invention. The print density sample sheet 10 of this embodiment is made of a transparent synthetic resin sheet as a base material, and is coated with an opaque white paint except for a large number of dots. Therefore, in this print density sample sheet 10, light is transmitted only through each dot portion.

The print density sample sheet 10 is divided into a first density area 11 to a fifth density area 15, and a dot size is determined for each of these density areas. However, the number of dots per unit area is constant in any of these density regions.

FIG. 2A shows the first concentration region 11 in an enlarged manner. The smallest dots 11a are arranged in the first density region 11. The area occupied by these dots 11a corresponds to 10% of the total area of the first concentration region 11.

As is apparent from FIG. 2A, an opaque white paint 17 is applied to the transparent synthetic resin sheet 16 except for the dots 11a.

In addition, in the second density region 12, small dots 12 a are arranged as shown in FIG. 2B, and the area occupied by these dots 12 a is the entire area of the second density region 12. Is 30% of the area.

Similarly, in the third density region 13, dots of average size are arrayed, and the area occupied by these dots is 50% of the total area of the third density region 13. Is. In the fourth density region 14, large dots are arranged, and the area occupied by these dots is 70% of the total area of the fourth density region 14.

Further, in the fifth density region, as shown in FIG. 2C, the largest dots 15a are arranged so as to overlap each other. The area occupied by these dots 15a is the fifth density region. 90% of the total area of 15.

The ratios of these occupied areas of 10% to 90% are written in the first concentration region 11 to the fifth concentration region 15 as shown in FIG.

Now, when this print density sample sheet 10 is overlaid on an arbitrary solid color and viewed through the print density sample sheet 10, this color is seen through each dot on a white background. The color density corresponds to the area occupied by the dots.

For example, in the first density region 11, the color is seen through each dot 11a, but since the area occupied by these dots 11a is only 10% of the entire area, a light color is seen. Further, in the second density region 12, the area occupied by each dot 12a is 30% of the entire area, so that a darker color than the first density region 11 can be seen. Similarly, in the third density region 13, the fourth density region 14, and the fifth density region 15, the area occupied by dots increases to 50%, 70%, and 90%, so that the colors become darker one after another. Go.

Therefore, if an arbitrary solid color is prepared, the print density sample sheet 10 is simply overlaid on this color to test the respective conditions when printing this color at five different densities. You can

In this embodiment, the opaque white paint is applied to the print density sample sheet 10. However, since this is printed on white paper, the color of each dot is represented on a white background, This is to show the concentration accurately. Therefore, when printing on a paper of another color, it is preferable to use a print density sample sheet obtained by applying a paint of another color except for the dot portions.

Further, as the color to be superimposed on the print density sample sheet, it is preferable to use a printing ink coated with printing ink.

Further, although the dot size is determined for each of the five density regions, various modifications can be made to the number and shape of these regions, or the arrangement method. Further, the size of each dot may be gradually changed from one end to the other end of the print density sample sheet without clearly defining these areas.

Further, the transparent minute portion is called a “dot”, but the shape of this dot is not specified. In other words, this dot corresponds to the minimum unit (pixel) of an image that represents a figure or character, and if this pixel is a circle or a square, or if it is a straight line or a curve, then the dot must also have those shapes. For example, in printing using special screens such as vertical lines or horizontal lines only, concentric circles, and sand, each pixel has its own shape, so it is necessary to match the dots to those shapes.

FIG. 3 shows an embodiment of a print density sample book according to the present invention.

As shown in this figure, the sample book body 31 is substantially flat and has a slot 32. A print density sample sheet 33 is bonded to the sample book body 31, and the print density sample sheet 33 serves as one wall of the slot 32.

The print density sample sheet 33 is almost the same as the print density sample sheet 10 shown in FIG. 1, and is composed of a transparent synthetic resin sheet as a base material and an opaque white paint applied thereto. The print density sample sheet 33 is divided into four density areas 34-1 to 34-4 and one solid area 35. In each of the concentration regions 34-1 to 34-4, the ratio of the area occupied by the dots is set to 20%, 40%, 60%, 80%. Further, the solid area 35 is not coated with white paint, and is formed of only a transparent synthetic resin sheet.

On the other hand, the sample book body 31 has a color chip holding area 36. An adhesive is applied to the color chip holding area 36, and the color chips 37-1 to 37-5 are attached thereto. These color chips 37-1 to 37-5 are solid-painted with different colors.

Here, for example, the color chip 37-5 is peeled from the color chip holding area 36, the color chip 37-5 is inserted into the slot 32 of the main body 31 of the book, and the color chip 37-5 is printed. View through sample sheet 33. As a result, in each of the density regions 34-1 to 34-4, the density of the color of the color chip 37-5 is increased at the respective densities corresponding to 20%, 40%, 60%, and 80% of the area occupied by the dots. You can see the condition. Further, in the solid area 35, the color of the solid paint can be seen.

Similarly, if each of the other color chips 37-1 to 37-4 is inserted into the slot 32 of the main body 31 of the book, the color of these color chips is also solid at each density. The paints can be compared.

As described above, by simply inserting one of the color chips into the slot 22 of the main body 31 of the book, it is possible to test the print density for each color. This color tip is easy to make as it only needs a solid color. Therefore, it is extremely easy to test the print density for various colors or new colors.

Although the color chip is held by the adhesive here, the color chip may be detachably held by another method. For example, a plurality of color chips are arranged on a mount, and a transparent sheet having an adhesive applied only on the periphery is covered on the mount to hold each color chip between the mount and the transparent sheet. In this state, the color of each color chip can be identified, and each color chip can be attached and detached by flipping the transparent sheet.

Further, instead of the structure in which the color chip is inserted into the slot 32 of the sample book body 31, one side of the print density sample sheet is fixed, and the print density sample sheet is unfolded to open the print density sample sheet. The color chip may be pulled down. Of course, the color chip may be modified.
