Press quality quantity measuring method is described in detail below with reference to Fig. 4 and Fig. 5.Firstly, executing step S1, obtain
The production information of printed matter.Before production printed matter, enterprise requires to preset the quality standard of printed matter, such as prints
Product need whether to need using text, pattern and the printed matter of required printing on the printing of what material, printed matter overlay film,
Size etc. after printed matter cutting, the production information of printed matter can be entered into computer 30 in advance by enterprise.In step S1,
Computer 30 first obtains the production information of the printed matter of corresponding batch, the target material information including printed matter.Wherein, target material
Material information is the information of the preset material for making the batch prints product, such as the printed matter of the batch is needed using paper
Or the materials such as cloth production.
Then, step S2 is executed, obtains the live material information of printed matter to be produced, live material information is placed into
In transmission belt 20 and prepare the information for being sent into the material that printer 21 is printed.Preferably, on the surface of the printed material
It is formed with identification information, such as two dimensional code, bar code perhaps text, symbol, pattern two dimensional code, bar code or text, symbol
Number, the identification informations such as pattern can be and be pre-printed on the surface of printing material, be also possible to the side by adhesive label paper
Formula is formed on the surface of the printed material.
In step S2, can by scanner scanning two dimensional code perhaps bar code then to two dimensional code or bar code into
Row identification is to obtain the material information that two dimensional code or bar code are characterized, to obtain live material information.If mark
Information is text, symbol, pattern etc., can be used photographic device shooting identification information, and to captured identification information into
Row identification, to obtain the live material information that text, symbol, pattern etc. are characterized.
Then, step S3 is executed, whether live material information acquired in judgment step S2 is consistent with target material information,
If it is inconsistent, executing step S4, information warning is issued, to notify operator to replace satisfactory printing material in time
Material.For example, information warning, or the display screen display in computer 30 can be issued by warning lamp or buzzer etc.
Text is warned, information warning can also be issued by modes such as short message, wechats.
If it is confirmed that live material information is consistent with target material information, S5 is thened follow the steps, carries out printing.Example
Such as, printer 21 is received from computer 30 needs the information such as the text, the pattern that print, and information is on printed material based on the received
Text, pattern required for printing is formed etc..
Then, step S6 is executed, the image information after obtaining printing, and image information is identified, obtain printing
Actual parameter information.Since printer 21 is provided with photographic device 32, after printing, photographic device 32 can be passed through
The image of semi-finished product after shooting printing identifies captured image to obtain image information, obtains practical beat
Parameter information is printed, such as obtains text, the line thickness actually printed.
Then, step S7 is executed, judges to print the requirement whether actual parameter information meets printing target component information.It beats
Print actual parameter information is printing actual parameter letter acquired according to the step S6 image information obtained and after being analyzed
Breath, and print target component information and be included in printed matter production information.In step S7, obtain in printed matter production information
Printing target component information, and will printing actual parameter information with print target component information compare, judge whether
It meets the requirements.
For example, the printing target component information of printing process may include text font, line weight, figure shading, figure
Case color etc., if character script does not meet preset font request in printing actual parameter information or line weight is not inconsistent
Preset requirement is closed, the judging result of step S7 is no, execution step S9, which is labeled as to print incomplete product,
Such as record the coding of the printing incompleteness product, place station etc..In this way, being transported to picking for production line end printing incomplete product
After device 28, it is moved in incomplete product collecting vessel 29 by device for eliminating 28.
If printing the requirement that actual parameter information meets printing target component information, S8 is thened follow the steps, is judged whether
It needs to carry out overlay film operation.Since not all printed matter requires overlay film, remember in the production information of printed matter
The information whether record needs overlay film to operate, if a certain printed matter does not need to carry out overlay film operation, making in information can remember
The information of overlay film do-nothing operation is recorded, that is, does not need the information of production overlay film operation.In this way, production of the computer 30 according to acquisition
Information may determine that whether the printed matter needs to carry out overlay film operation.If you do not need to carrying out overlay film operation, then executes and jump to
Step S14 carries out latter procedure, i.e. die cut operation, at this point, printed semi-finished product pass through film covering device 23 by transmission belt 20
But overlay film operation is not executed, and is admitted to die-cutting apparatus 25 after passing through film covering device 23.If necessary to carry out overlay film operation, then hold
Printed semi-finished product are transported to film covering device 23 by transmission belt 20 and are carried out overlay film and operate by row step S10.
Then, step S11 is executed, obtains image information coated with film, and identified simultaneously to the image information of acquisition
Obtain overlay film actual parameter information.Seemingly with printer class, the outlet side of film covering device 23 is provided with photographic device, in overlay film
After operation, photo coated with film is shot by photographic device, and photo coated with film is transmitted to computer 30, by calculating
Machine 30 analyzes photo coated with film, to obtain overlay film actual parameter information.In the present embodiment, overlay film actual parameter letter
Breath includes fold information, bubble shape or quantity, deviation information etc..
Then, step S12 is executed, judges whether overlay film actual parameter information meets the requirement of overlay film target component information.
For example, include overlay film target component information in the production information of printed matter, overlay film target component information be it is preset with
Bubble shape or quantity information are formed after the relevant information of coating processes, such as fold information coated with film, peritonaeum.Step S12
After obtaining overlay film target component information, and overlay film actual parameter information is obtained, actual semi-finished product are after judging coating processes
Whether the no requirement for meeting overlay film target component information, such as the number of bubbles of formation are less than preset quantity, and bubble size is
It is no to be less than preset size etc..
