Description
Technical field
The present invention relates to printing checking technical fields, more particularly to a kind of locating thermoprint detection method.In addition, of the invention
Further relate to a kind of locating thermoprint detection device including above-mentioned locating thermoprint detection method.
Background technique
There is a kind of first back baking scape to cover the printing technology being patterned on it again in printing process, this technique requires scalding
When metal working sequence produces, gold stamping pattern position is accurate, if gold stamping position deviation is larger, therefore product will become waster.Mesh
It is preceding to have no the gold stamping whether accurate method of pattern position of automatic easily method detection during gold stamping, for the gold stamping figure of solution
Case deviation problem, the method generally mainly used are as follows: allow offset printing process and gold stamping process synchronous production, will be produced in gold stamping process
Semi-finished product out, which are taken, carries out machine testing on offset press.The drawbacks of this mode, is: having fettered the flexible of scheduling of production
Property；Certain negative effect is produced to offset printing production efficiency；Because upper offset printing machine testing is cumbersome, therefore bronze designs or patterns on fans, wooden furniture, etc. position deviation cannot
Discovery in time；Increase the labor intensity of gold stamping board personnel；Unusual time, this method can not be implemented, and gold stamping pattern position detection is lost
There is the risk that quality of lot accident occurs in control.
To solve gold stamping pattern deviation problem, the method also used has: adding " ten " word gage line to examine in paper edge when gold stamping
It surveys.This mode drawback is: if " ten " word locating piece position is accurate, but the gold stamping pattern in part is sent out because of various factors midway
Raw displacement such as fails to enable the synchronous detection of offset printing, again at this time then the quality accident of the gold stamping pattern deviation of batch will occur.
When implementing the production of first ironing and then printing technique, under all one's effort control of multistage Quality Control unit, still repeatedly occur large quantities of
Measure the quality problems of gold stamping pattern deviation.This quality problems hold explosive have its source in: gold stamping pattern position can not be intuitive
Detection, so the position of hot stamping pattern is substantially at shape out of control when gold stamping.
In conclusion how to efficiently solve the easy deviation of gold stamping pattern, it is not easy the problems such as detecting, is current art technology
Personnel's urgent problem.
