Specific implementation mode
Chromatography unit is made of multiple stations, a kind of each color of station print.While printed patterns, by each station
Colour code be printed on blank position among pattern or material side.When each station colour code is perfectly aligned, that is, realize accurate chromatography.It should
Device can carry out automatically controlling printing vertical and horizontal, and use host and each printing station real-time exchange information, using mould
Block design, arithmetic speed are fast, control accuracy is high, dependable performance.Device, which has, to be manually controlled, automatically controls, and can mutually be cut
It changes.It is widely used in the automatic Overprint control of intaglio plate, flexible printing machine.
One video camera is set in each station that second station starts, the triggering frequency collection provided according to controller
The chromatography colour code of each station.The colour code of first station print and auxiliary calibration point are carried out image procossing by tablet computer, complete figure
As calibration, pixel value is converted into distance value, while subsequent work stations colour code obtains chromatography error in contrast, and be sent to control
Device and host.
The chromatography error that controller is provided according to tablet computer calculates adjustment amount using internal algorithm and is sent to execution machine
Structure changes the position of forme roller.
Host switches the real-time colour code image of each station by interchanger.
Display is used for showing and amplifying the colour code image of each station, a display can be arranged in the end of unit and cut
