Description
Technical field
The utility model belongs to printing machinery automatic control technology field.
Background technique
In printing color pattern, pattern is assigned in multiple printing plates by different colours, is successively printed onto printable fabric
Upper (such as Fig. 1).An accurate complete pattern is capable of forming when in order to guarantee successively to print, it is necessary to by colour code or sets of color patches
Detect printing registration deviation.It is current mainly have using on the printer for the colour code of registering system detection error both at home and abroad it is two big
Class:
The first kind is photoelectricity class colour code, and this colour code is generally in the shape of bar shaped mark, triangle mark or trapezoidal mark, see Fig. 2,
Fig. 3.Such as: a kind of three label printing plate group CN2905434Y, double end register sets of color patches CN103802449A of printing machine register control
Deng；Pattern was successively printed on printing together with corresponding colour code in printing by the first color printing plate, the second color printing plate ...
On material, two adjacent colour code distances have the gauged distance (such as 20mm) of setting in every group of colour code, are examined using photoelectric sensor
Two adjacent colour code distances are surveyed, are compared with gauged distance, the control of automatic printing register can be realized in deviation.
The shortcomings that photoelectricity class colour code is can only to be printed on printable fabric edge, to reserve the material side (5- for being printed on colour code
10mm), material sideline judge must be cut away in later process, to generate waste material, is wasted huge.
Second class is image class colour code, based on digital image processing techniques, using the camera shooting dedicated image class color of machine testing
Mark is to detect printing registration deviation.Image class colour code is mostly dot matrix, circle or circular arc type etc., sees Fig. 4.The advantages of image class colour code
It is that can be printed on not the blank position for influencing printing effect, is not take up rim charge, waste material, save the cost will not be generated.
Aforementioned two classes colour code compares, since image class colour code is to be not take up rim charge, no based on digital image processing techniques
Waste material is generated, there is biggish economic benefit, so having become the development of printing industry auto-alignment system using image class colour code
Trend.However, a set of printing plate of multicolour pattern printing is made of multiple printing plates, if printing house upgrades to image class color
Target detection system, the printing plate for being largely exclusively used in photoelectricity class colour code stored for many years cannot reuse, and all printing plates are all
It needs to make a plate again, this will increase very high plate change cost, also reduce the wish of printing house's replacement sophisticated equipment, hinder row
Industry technological progress.
Summary of the invention
In order to overcome the above problem, the utility model provides a kind of for detecting the multi-functional colour code of printing registration deviation
Group.The multi-functional sets of color patches cannot be only used for the automatic control of registration accurately system of the photoelectric sensor detection of photoelectricity class colour code, can also
With the automatic control of registration accurately system of the camera shooting machine testing for image class colour code, such printing house is by original photoelectricity class colour code
Detection system when upgrading to the detection system of image class colour code, original printing plate still can be used, reduce printing house more
The cost for changing sophisticated equipment is more conducive to the popularization and application of image class detection system.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
The multi-functional sets of color patches of the utility model is made of calibration point, addressing label and photoelectricity class colour code；

On the first color printing plate, for marking position of the sets of color patches on printing plate, provide by the position of altimetric image；
The photoelectricity class colour code can be bar shaped mark, triangle mark or trapezoidal mark；The photoelectricity class colour code is according to print
The color sequences of brush are separately positioned on each printing plate；
When photoelectricity class colour code is bar shaped mark, the calibration point is two dots or line segment near bar shaped mark；
When photoelectricity class colour code is triangle mark or trapezoidal mark, the calibration point is located at triangle mark or three angles of trapezoidal mark are attached
Three close dots or line segment, the position between each dot or line segment are relatively fixed；The calibration point is arranged in the first color printing plate
On, effect is to provide benchmark when carrying out image measurement for other coloured light electricity class colour codes printed later；
The multi-functional sets of color patches further includes single plate visual inspection line and comprehensive visual inspection line:
The single plate visual inspection line is arranged on the first color printing plate, for other coloured light electricity class colour code printing deviations of visual inspection and
Effect, shape can be right-angle line, cross hairs or multiple line segments composition；
The synthesis visual inspection line is arranged on the first color printing plate, and one and first is formed respectively on other printing plates
The visual inspection line of synthesis visual inspection line same shape on color printing plate, when printing with the synthesis visual inspection line phase mutual respect on the first color printing plate
It closes, effect is that the register partial difference printed to front carries out comprehensive visual inspection, and shape can be right-angle line, cross hairs or more
A line segment composition；
The single plate visual inspection line and comprehensive visual inspection line are located at the edge of other coloured light electricity class colour codes after the first color.
The photoelectricity class colour code is longitudinal arrangement respectively and transversely arranged there are two types of set-up mode in printing；
When photoelectricity class colour code is longitudinal arrangement, addressing label is located at the top of the photoelectricity class colour code of the first color.
When photoelectricity class colour code is transversely arranged, addressing label is located at the top or left end of the first coloured light electricity class colour code.
The calibration point is located at the symmetric position of the upper and lower two sides after the first color near other coloured light electricity class colour codes；
Alternatively, the calibration point may be alternatively located at the same side after the first color near other coloured light electricity class colour codes.
The essence of the utility model be can only with photoelectric sensor detect colour code change into can with camera shooting machine testing
Image class colour code, to achieve the purpose that be measured with based on digital image processing techniques；The utility model expands figure
As the application range of class detection system, have in the automatic control of registration accurately of the printing machines such as intaglio plate, soft version, rotation extensive practical
Value has high economic benefit and social effect.
The beneficial effects of the utility model are:
The printing house that there is image class colour code automatic control of registration accurately system, it is only necessary to by a set of (N number of) original photoelectricity
The first color printing plate in class colour code printing plate is changed to the multi-functional sets of color patches (not including digital in figure see Fig. 8) of the utility model,
The primary colors mark of remaining N-1 printing plate remains unchanged, it is not necessary to change a full set of printing plate, save the expense of N-1 printing plate of replacement.
