Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
As shown in Figure 1, in present embodiment, printed article quality check system comprises error coefficient determining device 11, analog image generating apparatus 12 and check result determining device 13, and analog image generating apparatus 12 comprises point version unit 121, simulation error unit 122 and closes edition unit 123.
Error coefficient determining device 11, for will pay the various working conditions of printing according to original copy to be checked, is determined error coefficient, the various error components that affect printing effect in described error coefficient Neng Gou anti-Showing-that-momentum-turning printing process.
Analog image generating apparatus 12, for the impact on printing effect according to described error coefficient reflection print production condition, generates the analog image after experience error event according to the image generation approach of simulate press production process.Wherein, divide version unit 121 for original copy pictorial element on different formes in the time printing is separated and divided into groups by forme; Simulation error unit 122, for fiducial error coefficient expression formula, carries out computing according to error coefficient expression formula respectively by the information of pictorial element group; Close edition unit 123 for the pictorial element that carried out the different formes after computing is combined by original datum mark, then carry out overlapping processing and obtain simulate press image.
Check result determining device 13, for described analog image and described original copy are contrasted, is analyzed the situation that figure or pictorial element are even lost in decay has been occurred, and provides accordingly check result.
As described in Figure 2, the method that adopts system shown in Figure 1 to realize the inspection of printed article quality comprises the following steps:
(1) error coefficient determining device 11 will be paid the various working conditions of printing according to figure to be checked or image manuscript, determine error coefficient.The various error components that affect printing effect in described error coefficient Neng Gou anti-Showing-that-momentum-turning printing process.
In actual production, the error component that affects printing effect is many-sided.There is external environment aspect factor, as temperature, humidity, also have the alignment precision between precision and the different forme of printing machine itself, also have plate-making quality and the precision of forme.Meanwhile, different error components are also different for the influence degree of printing quality.For example, registration error can cause show money or valuables one carries unintentionally and light color overflow; The impact of temperature, humidity etc. can be many-sided.
Error coefficient is the weighting reflection of above all factors, can be or a series of expression formula that above various factors integrates, but acting in conjunction is in final printing effect.Concrete numerical value wherein and operation relation are based upon on empirical analysis basis, i.e. statistics and data analysis based on error event in the record of print production in the past.In addition, because above-mentioned error component may be constantly to change, so the formulation of error coefficient also needs the trend looking to the future or occurent various error event changes, and revise on this basis.Accordingly, the error coefficient expression formula of formulating under different working conditions may have certain reference significance, but does not possess the value of directly quoting.
Taking registration error as example.Its error form of expression may be defined as forme relative datum point in horizontal plane and displacement has occurred for (wherein Δ x and Δ y are arbitrarily positive negative value for Δ x, Δ skew y).Be reflected in print result for the relative tram of printing net-point corresponding displacement occurs for (the statement formula of registration error is bivector for Δ x, Δ dislocation y).
If passing record of production demonstration, registration error is larger on the impact of printing quality, and the absolute value of two components in aforementioned displacements expression formula needs corresponding increase so.On the contrary, if along with participating in the raising of workman's operating technology of printing registration, the generation of registration error event will constantly reduce.Even may be because introduce new technology or new equipment, cause the probability that registration error event occurs significantly to reduce in a short time.Also the value that will revise in time in this case Δ x and Δ y, reduces it, is ignored even where necessary.
Moreover, before, mentioning temperature and humidity also may make a difference to alignment.These two factors may linearly be amplified registration error, and the expression formula of registration error can expand to so: t × (Δ x, Δ y).Wherein t is temperature and humidity coefficient of colligation, and its value is not less than 1.Obviously t is larger, and registration error end value is larger; And the impact of temperature and humidity can be ignored in the time of t=1.
(2) analog image generating apparatus 12 impact on printing effect according to described error coefficient reflection print production condition, generates the analog image after experience error event according to the image generation approach of simulate press production process.
The approach that generates analog image can be multiple, can be computer software programs simulations, can be also printer printing etc.Its process is the impact of original picture proof being applied to above-mentioned error coefficient, and matches with the result of the printing process carrying out.
Realize register trouble as example taking computer software programs simulation, as shown in Figure 3, comprise the following steps:
1. divide 121 points of edition unit version: by original copy, the pictorial element on different formes separates and divides into groups by forme in when printing;
2. simulation error unit 122 simulation error events: quote described registration error expression formula, the positional information that some pictorial element group of dislocation may occur is carried out respectively displacement computing.
3. close edition unit 123 and close version: the pictorial element of the different formes that carried out displacement computing is combined by original datum mark, then carry out overlapping processing and obtain simulate press image.
Wherein, the concrete form of displacement computing is as follows:
P
1(i)=P
0(i)+t×(Δx，Δy)
Wherein, P
0and P (i)
1(i) represent respectively to occur the position, site before and after registration error.
If generate analog image in printer printing mode, also comprise above-mentioned three steps.First divide version by forme separate picture element, then to quote the computing that misplaces of registration error expression formula be simulation error event, the pictorial element that finally goes out each forme at the upper overstriking of physics printed medium (as paper etc.) closes version.
For other error coefficient expression formulas, adopt equally said method by the influence of this error coefficient on simulate press image.The final simulate press image generating is the Overlay of multiple said process.
(3) check result determining device 13 contrasts described analog image and described original copy, analyzes the situation that figure or pictorial element are even lost in decay has occurred, and provides accordingly check result.
As shown in Figure 4, Fig. 4 a is original copy, and Fig. 4 b is analog image.Known by contrasting: the vertical moulding in Fig. 4 a has shown that the registration error existing due to copy printing causes color to be overflowed, and ledgement and star graphic have been lost after decay, and word thickens unclear after decay.The check result providing is accordingly more directly perceived and accurate.
Obviously, those skilled in the art can carry out various changes and modification and not depart from the spirit and scope of the present invention the present invention.Like this, if these amendments of the present invention and within modification belongs to the scope of the claims in the present invention and equivalent technology thereof, the present invention is also intended to comprise these changes and modification interior.
