Pulse out is measured, and each pulse represents plug and the different Angle Position of tank body thereon；On the other hand, because of digital photo
May be considered and be made of equally distributed pixel-matrix (each pixel has different gray scales, and minimum gray scale is 0, i.e., without
Color), so, above-mentioned expanded view can also be with picture essentially like usually measuring in circumferencial direction.Then it is just built in circumferencial direction
Two coordinate systems have been found, have been referred to as " angle pulse coordinate system " and " picture pixels coordinate system " here, it is clear that the two coordinates
System is to measure or describe same width figure with different units, therefore the two has fixed linear corresponding relation.Each picture in figure layer
Element all corresponds to an angle position defined by angle pulse in " angle pulse coordinate system ".If a pixel is located at two angles
It spends between pulse, then distance of the pixel away from previous angle pulse is estimated by data processing unit, as the pixel is in " angle
The fractional part of angle position in pulse coordinate system ", and the position of " previous pulse " is then the integer portion of the pixel angle position
Point, integer part and fractional part together form coordinate value of the pixel in " angle pulse coordinate system ".Whenever plug (band
Dynamic tank body) it rotates and reaches at the corresponding angle pulse coordinate of a certain pixel, data processing unit just generates a firing pulse,
It controls corresponding spray head and sprays ink droplet, respective pixel is generated on tank body.The corresponding angle arteries and veins of first pixel of picture (or figure layer)
Rush the initial position that coordinate value is defined as picture (each figure layer).In this way, each figure layer of picture along the circumferential direction each location of pixels at " angle
There is corresponding coordinate value in degree pulse coordinate system ".Thus corresponding relationship between pixel and plug absolute angular position is just established
Get up.
Third step S3 maps particular pair of bit relationship
By digital signal processor (dsp chip) by the particular pair of bit relationship of the current plug obtained in second step, the core is followed
Stick is mapped in remaining next print stations, establishes the absolute of pixel and the plug of remaining print stations digitlization figure layer

The expanded view of circumferential surface, the digitlization figure layer of each print stations are to decomposite to come from same picture, are had between each figure layer solid
Some corresponding relationships, as long as therefore by second step establish start-print station digitlization figure layer 3 coordinate projection (or referred to as
Move) in the digitlization figure layer 4 of remaining print stations, just establish the pixel of remaining print stations digitlization figure layer 4 with should
Corresponding relationship between the absolute angular displacement (or Angle Position) of plug.
Concrete operations may is that each pixel institute of the printing head printing according to the start-print station of second step record
The angle position in " the angle pulse coordinate system " of plug is corresponded to map, so that the printing head for obtaining remaining print stations is wanted
Angle position in " the angle pulse coordinate system " of plug corresponding to the pixel of printing.
4th step S4 completes remaining printing
The digitlization figure layer printing of remaining print stations is completed by the corresponding relationship that third step is established, moving in circles with this, it is every to realize
The precise Printing of a tank body text or pattern.
Concrete operations are: according to core corresponding to the printing head pixel to be printed of remaining print stations of third step acquisition
