[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this is not to limit the scope of the present invention.

[0019] like Figures 1 to 3As shown in this embodiment, an offset printing control strip includes multiple triangular blocks 1. The size of the triangular blocks 1 can be freely set, and the number of triangular blocks 1 can be freely set according to actual printing requirements. The multiple triangular blocks 1 are sequentially spliced ​​together to form multiple square blocks 2 and multiple parallelogram blocks 3. The multiple square blocks 2 are arranged side by side with shared sides, that is, each square block 2 is arranged side by side in the horizontal direction, and adjacent square blocks 2 share the same side length. The two hypotenuses of each parallelogram block 3 are the diagonals of two adjacent square blocks 2. The hypotenuses of the two triangular blocks 1 spliced ​​together to form the square block 2 share the diagonal of the square block 2. The triangular blocks 1 are equilateral right triangles. The triangular blocks 1 are filled with at least one of printing plates C, M, Y, and K. In this embodiment, preferably, the number of triangular blocks 1 is even, such as eighteen triangular blocks 1, thereby forming nine square blocks 2 and eight parallelogram blocks 3 arranged side by side; the multiple square blocks 2 are arranged side by side in a rectangular strip structure. In this embodiment, the square blocks 2 and parallelogram blocks 3 formed by splicing the triangular blocks 1 are horizontally and vertically aligned and located on the same baseline.

[0020] This embodiment sets up multiple triangular blocks 1 to form multiple square blocks 2 and multiple parallelogram blocks 3 in sequence. Each triangular block 1 is filled with at least one of the printing plate C, M, Y, and K. Different color combinations or overprints can be filled in the triangular or combined shapes to achieve the detection of two-color, three-color, or four-color values, making the structure more flexible. Thus, without increasing additional costs, it can be directly added to the end of the printing plate of the printed material or the corresponding position to be detected to achieve the effect of color measurement and overprinting, so as to obtain the required information from the entire printed image and effectively improve the printing quality.

[0021] During testing, the printing color data can be obtained by directly using a tester to detect the corresponding position of the control bar. The registration accuracy or deviation can be determined by using a magnifying glass with a scale or an infrared detector, which can then guide how to adjust the printing color and registration accuracy.

[0022] In this embodiment of the offset printing control strip, the side length and line width of the triangular block 1 are further set to 0.03mm; with this setting, the lines are thinner, making it easier to control the deviation distance, deviation direction and registration operation.

[0023] In one embodiment of the offset printing control strip, such as... Figure 2 As shown, the printing plates C, M, Y, and K are filled sequentially starting from the second triangular block 1.

[0024] For example, Figure 2 As shown, for the three-color printing of printing plates C1, M1, and Y1, it can be directly determined by checking whether the horizontal, vertical, and diagonal lines of the triangular blocks 1 are all on the same baseline.

[0025] For example, press triangle block 1... Figure 2 The labels are as follows: C1, M1, Y1, K1; C2, M2, Y2, K2; C3, M3, Y3, K3; C4, M4, Y4, K4. These labels are then filled with their corresponding colors to form control strips for color detection. The placement can be freely set according to actual printing requirements. Different color combinations or overprints can be filled into triangles or combined shapes to achieve the detection of two, three, or four color values, offering greater structural flexibility. If the paper is deformed or the ink volume is uneven, the detection results of the corresponding areas can be used to adjust the ink and water status of the printing press in a timely manner, maintaining a balance in the detection values ​​of different areas.

[0026] Furthermore, printing plates Y and M (i.e., Y1 = Y + M) can be filled in triangular block 1Y1. The color value steps of printing plates Y and M can be subdivided into any value from 0 to 100% or specific color values ​​for filling. Printing plates Y or M (i.e., M1 = Y or M) can be filled in triangular block 1M1. The color value steps of printing plates Y or M can be subdivided into any value from 0 to 100% or specific color values ​​for filling. In this way, the density or chromaticity values ​​of mixed colors and monochrome colors can be detected.

[0027] Also, such as Figure 2 As shown, adjacent squares or parallelograms in the triangular block 1, labeled C2, M2, Y2, K2, C3, M3, Y3, K3, and C4, M4, Y4, K4, can be filled with the same or specified single-color or two-color mixture to test color data.

[0028] In another embodiment, such as the offset printing control strip of this example, Figure 3 As shown, the printing plates C, M, Y, and K are filled sequentially from the even-numbered triangle blocks 1 and sequentially from the odd-numbered triangle blocks 1. Specifically, the first group of printing plates C, M, Y, and K are filled sequentially from the even-numbered triangle blocks 1, the second group of printing plates C, M, Y, and K are filled sequentially from the odd-numbered triangle blocks 1, and then the third group of printing plates C, M, Y, and K are filled sequentially from the even-numbered triangle blocks 1 again, and so on.

[0029] For example, triangular block 1 is pressed... Figure 3As shown, the triangular blocks 1 are identified as C1, M1, Y1, and filled with any three-color mixed color, and the color value ladder can be subdivided into 0-100% of any value or filled with specific color values. The triangular blocks 1 are identified as C2, M2, and filled with any single color or two-color mixed color, and the color value ladder can be subdivided into 0-100% of any value or filled with specific color values. In this way, the density values or chroma values of the mixed color and the single color can be detected.

[0030] As shown, the triangular blocks 1 are identified as C1, M1, Y1, and filled with any three-color mixed color, and the color value ladder can be subdivided into 0-100% of any value or filled with specific color values. The triangular blocks 1 are identified as C2, M2, and filled with any single color or two-color mixed color, and the color value ladder can be subdivided into 0-100% of any value or filled with specific color values. In this way, the density values or chroma values of the mixed color and the single color can be detected. Figure 3 As shown, the triangular blocks 1 are identified as C1, M1, Y1, and filled with any three-color mixed color, and the color value ladder can be subdivided into 0-100% of any value or filled with specific color values. The triangular blocks 1 are identified as C2, M2, and filled with any single color or two-color mixed color, and the color value ladder can be subdivided into 0-100% of any value or filled with specific color values. In this way, the density values or chroma values of the mixed color and the single color can be detected.

[0031] The above is only a preferred embodiment of the present application, so any equivalent changes or modifications made according to the structure, features and principles described in the patent application of the present application are included in the protection scope of the patent application of the present application.
