Abstract
The utility model discloses a three-mark plate set for automatic overprint by printing machines. Two marks with a certain distance between them are first made on the benchmark plate, and form an overprint blank, and then an overprint mark is made on the overprint plate that corresponds to the middle of the benchmark plate, thereby forming a plate set. The benchmark plate can be selected freely, so the utility model allows detection in a small range that includes the target plate set, facilitates the selection of the single-spot photoelectric head to match the light source color, avoids color missing in detection and incorrect detection, provides high precision, allows flexible plate arrangement and accurate overprint, and realizes the single-benchmark plate set sequence based on the first-color plate or the second-color plate and multiple-color overprint.
Description
Technical field
The utility model relates to a kind of printing machine automatic overprint with three mark forme groups.
Background technology
On the combined type rotary press, generally all be provided with rotary encoder at present,, cause the cumulative errors of many benchmark owing to be the general colour code that adopts the preceding look of back look cover.And for example " printing automatic overprint colour code type rotary encoder " (patent No. 00230667.0), first forme made synchronous head, for automatic addressing provides condition, the chromatography space that has made some after the synchronous head, follow-up cover forme is made the chromatography mark in center, corresponding space, extremely in particular cases uneven at the printing element background color, cause the situation of leaking look and flase drop that detects easily.
Summary of the invention
The purpose of this utility model just provides a kind of printing machine automatic overprint with three mark forme groups, with three indexing unit groups as detected object, by the oscillograph addressing, determine detected object with the ripple door, adopt the best fit of light source colour and marker color coupling, realize minizone searching and detecting object, avoid the influence of the extremely uneven special circumstances of printing element background color.
The purpose of this utility model is achieved in that a kind of printing machine automatic overprint is with three mark forme groups, comprise reference colours forme, chromatography forme 4 and probe 6, the reference colours forme along the circumferential direction is provided with two benchmark colour codes 1,2 separated by a distance, form chromatography space 5 between two benchmark colour codes, the chromatography colour code 3 that can be filled in corresponding center, space is set on the chromatography forme 4, constitutes one three indexing unit group by two benchmark colour codes 1,2 and chromatography colour code 3.
Above-mentioned printing machine automatic overprint is with three mark forme groups, and the shape of three marks can adopt rectangle, trapezoidal, triangle.
Owing to adopt said structure, the utility model has been avoided the cumulative errors that many benchmark of look cause before the look cover behind the general colour code, avoided the error compensation that general colour code makes people's headache,, determined detected object with the ripple door by the oscillograph addressing, adopt the best fit of light source colour and marker color coupling, realize minizone searching and detecting object, avoid the influence of the extremely uneven special circumstances of printing element background color, detect and do not leak look, flase drop not, the precision height.Three mark forme groups can divide into groups to place, and arrange flexibly, can be placed on the pattern blank space so that save raw material.Can horizontally-arranged, to be suitable for the printing of tube material, can extensively be suitable for various raw material printings.
Description of drawings
Below in conjunction with embodiment the utility model is further described.
Fig. 1 is three mark principle schematic of the present utility model
Fig. 2 is a structural representation of the present utility model.
Multiple-unit group instance graph when Fig. 3 is a polychrome printing of the present utility model.
Fig. 4 is three indexing unit picture groups of the trapezoidal colour code of employing of the present utility model.
The specific embodiment
A kind of printing machine automatic overprint is with three mark forme groups, comprise reference colours forme, chromatography forme 4 and probe 6, the reference colours forme along the circumferential direction is provided with two benchmark colour codes 1,2 separated by a distance, form chromatography space 5 between two benchmark colour codes, the chromatography colour code 3 that can be filled in corresponding center, space is set on the chromatography forme 4, constitutes one three indexing unit group by two benchmark colour codes 1,2 and chromatography colour code 3.
Among Fig. 1,1 and 2 two marks that provide for the basis frontage forme constitute the chromatography space thus, and 3 are the chromatography mark, are produced on the center, space.
Among Fig. 2,4 are the chromatography forme, and 3 are the chromatography mark, and 6 is the single spot probe.By photoelectric scanning head scanning colour code, obtain the pulse train ripple, find the detection target group by the oscillograph addressing again, open a detection window, detect the range difference of chromatography marking path front and back two marks, thereby determine overprint error, offer the chromatography control system and revise.Because be that the ripple gate-type detects the object element group, can adopt the best fit of light source colour and marker color coupling, realize minizone searching and detecting object-unit group, avoid the influence of the extremely uneven special circumstances of printing element background color, guarantee to detect and do not leak look, not flase drop.
Fig. 3 shows the example of making of one group of five colors version, provide three to form unit group Z1, Z2, the Z3 that goes here and there by the first look forme A, B, C, D, E are respectively the chromatography mark of second look, the 3rd look, the 4th look and multicolored forme, the basis frontage forme can be selected arbitrarily, can be the first look forme, can be the second look forme, can be the forme of the color in front, the 4th forme realizes with the 4th look being the chromatography of benchmark also for the 5th forme provides a chromatography space Z4 among the figure.Three indexing unit groups can divide into groups to place; Can be put in the blank space of pattern, to save raw material; Can the row of indulging, also can horizontally-arranged.Layout is flexible and changeable.
In the embodiment of Fig. 4, change the mark among Fig. 1 into trapezoidal colour code, thereby can realize detecting to overprint error in length and breadth.
