It is said that the flat screen printer is omnipotent, as long as you want to print, there is nothing that cannot be printed. Is it really? Let’s follow me to popularize science for everyone.
First of all, we need to know that the printing methods of flat screen printers are generally divided into three types, one is manual printing, the other is mechanical printing, and the last is live screen printing.
One: manual printing
Manual printing refers to the up and down movement of the printing plate, and the scraping and printing are all manual operations from the feeding of the paper to the delivery of the paper.
Two: mechanical printing
Mechanical printing means that the printing process is completed by mechanical actions. Among them, it is divided into semi-automatic and fully automatic printing. Semi-automatic means that the substrate is put in and taken out by manual operation, and printing is completed by machinery; fully automatic means that the entire printing process is completed by machinery.
Three: Live screen printing
Live screen printing is to remove the screen layout and directly adhere to the surface of the substrate for printing. Using the live screen printing method, a large number of processed printed products can be printed, such as latex plastic buckets, pure water buckets, washbasins, thermos bottles, cups, bowls, plates, and other products. At the same time, this method can be used to print signs on cars, and can also be printed on special-shaped planes.
The production of the live screen: first dry and repair the photosensitive text and graphic plate, then take it off and cut it according to the size. And use wood chips or aluminum sheets as the skeleton at both ends of the screen to be tightly fixed with adhesive tape, or directly glued with glue, so that the required active screen can be made.
The operating method of the live screen: select different printing materials according to the substrate to be mixed: first select the plate and the plate, and mix the ink, and then, one person holds the live screen with both hands, and the printed part is tightly attached to the substrate. On the surface, another person uses a squeegee to evenly dip the ink on the upper mouth surface of the squeegee and then places the squeegee on the ink adjustment plate evenly on the plate surface for uniform scraping.
If the printed graphics area is too large, you can pour the ink on the plate according to the situation, but do not let the ink flow out of the substrate. Pay attention to the blended ink not to be too thin or too dry, it is better to dry and wet moderately. Small-area printing and painting can be operated by one person. The method is to stick one end of the movable plate with packaging tape on the required position of the substrate machine, and then use the other hand to tighten the printing plate against the substrate. Print it.
Note for starting the plate: Be sure to start the plate lightly in the direction of the tape that is pasted. This is also the case if two people operate the plate advertising. This method is used for printing, which is convenient to operate, flexible to substrates, and can be large and small. Can be more or less, with the advantages of low cost and energy saving.
