1. Printing characteristics of glass screen printing machine

The characteristics of    glass screen printing machine are summarized as follows:

  ① Screen printing can use many types of inks. Namely: oily, water-based, synthetic resin emulsion, powder and other types of inks.

  ②The layout is soft. The screen printing layout is soft and has a certain degree of flexibility not only for printing on soft objects such as paper and cloth, but also for printing on hard objects, such as glass, ceramics, etc.

  ③Silk-screen printing has low printing force. Since the pressure used in printing is small, it is also suitable for printing on fragile shopping objects.

  ④The ink layer is thick and the covering power is strong.

  ⑤ It is not limited by the surface shape and area of u200bu200bthe substrate. It can be seen from the foregoing that screen printing can not only print on flat surfaces, but also on curved or spherical surfaces; it is not only suitable for printing on small objects, but also for printing on larger objects. This printing method has great flexibility and wide applicability.

Two, glass screen printing machine printing method

   There are usually two types of glass screen printing machines, namely manual printing and mechanical printing.

  Manual printing refers to the manual operation of the up and down movement of the printing plate, and the scraping and printing from paper feeding to paper delivery.

  Mechanical printing means that the printing process is completed by mechanical actions. Among them, it is divided into semi-automatic and full-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.

   There is also a fast and easy curved screen printing method, live screen printing, that is, the screen layout is removed and directly attached 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    live-face screen plate: 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 to mix according to the substrate: first select the plate and the plate, and mix the ink, and then one person holds the live screen with both hands to tighten the printed part Stick it on the surface of the substrate, another person uses a squeegee to evenly dip the ink on the upper surface of the squeegee, and then place the squeegee on the ink adjustment plate evenly on the layout 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 mixed 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 to the desired position of the substrate machine with packaging tape, and then use the other hand to tighten the printing plate against the substrate. Print it.

  Pattern-up note: Be sure to start the version lightly according to the direction of the tape one end, if two people operate the version-up advertisement, printing with this method is convenient for operation, flexible and capable of printing substrates. It is small, the quantity can be more or less, and it has the advantages of low cost and energy saving.
