The utility model provides an offset printing overprinting mark printing plate, through set up the mark figure on the printing plate, form the combination of mark symbol after offset printing overprinting, through observing the combination of reference numeral alright know which overprinting of color printing ink is not accurate, control the deviation distance more easily, deviation direction and register operation promote the precision of overprinting.
In the printing plate, one basic color ink is used as a reference, and black ink is generally used, so that the difference is easy to see, or a special color ink is used as a reference, so that the problem of difficult registration caused by thickening after multi-color overlapping is avoided. Wherein a pattern formed by the reference circular mark block 1 and the reference cross mark block 2 is provided in the reference mark group, a plurality of the calibration mark blocks 3 are provided above the reference circular mark block 1, the number of the calibration mark blocks 3 is determined by the sum of the numbers of the base color mark group and the spot color mark group, and the number "1" is marked on the calibration mark block 3 to indicate that it is the reference group. The primary color marking group is a group which is usually used as basic color in offset printing, wherein the size of a combined graph of the primary color circular marking block 4 and the primary color cross marking block 5 is consistent with that of the reference mark group, the vertical line of the first L-shaped marking block 6 and the vertical line of the primary color cross marking block 5 are positioned on the same straight line, the horizontal line of the first L-shaped marking block 6 is flush with the horizontal line of the corresponding reference cross marking block 2 positioned in the reference mark group, and simultaneously, the first L-shaped marking block 6 is marked with group numbers for facilitating subsequent viewing. Since the pattern of the first L-shaped mark block 6 and the pattern of the reference cross mark block 2 are centrosymmetric patterns, after offset overprinting, the first L-shaped mark block 6 and the reference cross mark block 2 are combined to form a cross, and the combined pattern of the primary color circular mark block 4 and the primary color cross mark block 5 coincides with the combined pattern of the reference circular mark block 1 and the reference cross mark block 2. After offset printing overprinting, if the situation that the circular structure is not coincident with the cross structure occurs, it is proved that a certain color of printing ink makes mistakes in the overprinting process, and then the staggered cross combination above is used for determining which group of printing ink has problems in printing, so that accurate detection can be achieved, the deviation distance and the deviation direction can be mastered, and subsequent adjustment is facilitated.
The spot color mark group is a group of some special printing inks, and in order to distinguish the spot color mark group from the previous reference color, the notch 9 is designed on the spot color cross mark block 8, and the spot color cross mark block cannot be completely overlapped with the reference cross mark block 2 after overprinting, so that the distinguishing effect is achieved. The combined graph of the spot color circular mark block 7 and the spot color cross mark block 8 is consistent with the size of the reference mark group, the vertical line of the second L-shaped mark block 10 is positioned on the same straight line with the vertical line of the spot color cross mark block 8, the horizontal line of the second L-shaped mark block 10 is aligned with the corresponding horizontal line of the reference cross mark block 2 in the reference mark group, and meanwhile, the second L-shaped mark block 10 is provided with group numbers to facilitate subsequent bid marking. Since the pattern of the second L-shaped mark block 10 and the pattern of the reference cross mark block 2 are centrosymmetric patterns, after offset overprinting, the second L-shaped mark block 10 and the reference cross mark block 2 are combined to form a cross, and the combined pattern of the spot color circular mark block 7 and the base color cross mark block 5 coincides with the combined pattern of the reference circular mark block 1 and the reference cross mark block 2, but the shape of the notch 9 appears. After offset overprinting, if the notch 9 is missing or the notch 9 is displaced, the special color ink in the overprinting process is proved to be wrong, and then the special ink in which group is printed is determined to be problematic through the staggered cross combination above. Through foretell design, then need not observe the finished product effect after the overprinting, can only confirm the problem place of printing process through the figure coincidence and the combination condition of observing the mark, easily quality testing personnel detect the registration problem, and convenient adjustment promotes the printed matter quality. In order to ensure the accuracy of the marking, the thickness of all the lines of the graph is set to be 0.03mm, and the subsequent size adjustment can be facilitated by the uniform size.
As shown in fig. 1, in this embodiment, the reference mark group is made of a K plate (black) and the primary color mark groups are made of a C plate (cyan), an M plate (magenta) and a Y plate (yellow), two color mark groups are provided, i.e., an S1 plate and an S2 plate, respectively, and the color mark groups may be special inks such as gold ink, silver ink and pearl ink. The overall effect of the mark after offset overprinting is shown on the far left side of fig. 1, and if the mark after overprinting is distinguished from the effect, errors in offset printing are proved, and meanwhile, the group in which the problem occurs can be known through the number of the group, so that the accuracy of overprinting is improved.
The foregoing is a more detailed description of the present invention, taken in conjunction with the specific preferred embodiments thereof, and it is not intended that the invention be limited to the specific embodiments shown and described. To the utility model belongs to the technical field of ordinary technical personnel, do not deviate from the utility model discloses under the prerequisite of design, can also make a plurality of simple deductions or replacement, all should regard as belonging to the utility model discloses a protection scope.
