E≤2 average color difference △ of all color lumps of the two；
3, contrast standard color space 3 and the digital sample printing color space 4 obtained using 9 process color target 1 of digital sample printing machine,
The ratio of the total color lump of color lump Zhan of E≤3 color difference △ is more than or equal to 85%.
It is verified using quality of colour of the standards of chromatic aberration to digital sample printing color space 4, guarantees to use digital sample printing color
The digital sample that color color space 4 is drawn a design close to the color for using normal procedure to produce, guarantees the matter of digital sample printing as far as possible
Amount.
Step 5: handling data original copy 6 using digital sample printing characteristic file 5, and modify the resolution ratio of data original copy 6, make it
Meet resolution standard, generates new data original copy 6.Step 5 further comprises:
Step 51: data original copy 6 being handled according to digital sample printing characteristic file 5, adjusts the resolution ratio of data original copy 6；
Step 52: comparison is adjusted using the resolution ratio of 8 printed data original copy 6 of printing machine and using the printing of digital sample printing machine 9
The resolution ratio of data original copy 6 afterwards, judges whether it meets resolution standard, if not conforming to symbol executes step 53；If meeting execution
Step 54；
Step 53: readjusting the resolution ratio of data original copy 6, and execute step 52；
Step 54: the data original copy 6 for meeting resolution standard is set as final data original copy 7；
Using this method for repeating to adjust 6 resolution ratio of data original copy, point printed using digital sample printing space 4 can be made
Resolution as far as possible closing to reality production using resolution ratio printed by printing machine 8, the digital sample produced sufficiently is sent out
Wave the effect of sample.
In the present embodiment, resolution standard are as follows: printed using 8 printed data original copy 6 of printing machine and using digital sample printing machine 9
Data original copy 6 adjusted is brushed, the lines of identical line width, width difference≤0.05mm of two lines are compared.
It is adjusted by the resolution ratio to data original copy 6, so that 6 resolution ratio of data original copy adjusted increases, is also increased
The big resolution ratio that data original copy 6 adjusted is printed using digital sample printing machine 9, so that the number got using digital sample printing machine 9
Code sample meets the requirement of resolution ratio.
After generating final data original copy 7 using above-mentioned original copy method of adjustment, it is former that final data is printed using digital sample printing machine 9
Original text 7 generates digital sample.As one embodiment, final data original copy 7 is printed on tinplate using ink-jet printer, is generated
Tinplate sample.
The present invention first uses 8 printing standard IT8.7/3 color target 1 of printing machine, and uses X-Rite Eye-On color management system
System 2 generates profile connecting space 3, reference standard color space 3, using color management system 2 constantly to digital sample printing color
Space 4 is adjusted, and so that it is met standards of chromatic aberration, then using 8 printed digital original copy 6 of printing machine as standard, pass through continuous logarithm
The resolution ratio of code original copy 6 is adjusted, and is generated and is met the resolution ratio final digital original copy 7 to be gone, finally uses ink-jet printer
The final digital original copy 7 of printing generates tinplate sample.The tinplate sample generated in this way, work efficiency is high, color control
Stablize, and resolution ratio is also able to satisfy needs, it, also can fast fast-growing after client is adjusted the data original copy 6 that needs print
At required final data original copy 7, to rapidly respond to the demand of client, meet market demands complicated and changeable.
A kind of other structures of the digital sample printing method applied to tinplate described in the present embodiment are referring to the prior art, herein
It repeats no more.
