(Summary description)SMT Screen Printing Common Terms 1 open stencil area 　　 　　The sum of all image areas on a screen printing stencil. 2 open mesh area percentage 　 　　Screen all mesh area and the corresponding ratio of the total area of the screen, expressed as a percentage. 3 printing 　　 　　The use of letterpress, lithographic, intaglio, screen or other image carriers, colored or colorless media (such as ink) transferred to the substrate on the reproduction process. 4 outer frame dimension 　　 　　In the horizontal position of the screen frame, including all parts of the screen frame, including the product of the length and width. 5 printing former 　　 　　A kind of printing graphic carrier through the ink transfer will be copied to the image on the substrate. 6 printing head 　　 　　A part of a printing machine that provides the necessary pressure for ink transfer by moving against the printing plate. 7 printing ink 　　 　　A substance that is applied to a substrate during the printing process. 8 printing side(lower side) 　　 　　The bottom side of the screen printing plate, i.e., the side of the ink in contact with the substrate. 9 rotary screen printing 　　 　　The process of screen printing using a cylinder printing plate. The plate rotates in synchronization with the substrate to produce continuous graphics. The ink is supplied from the inside of the cylinder printing plate and the squeegee is mounted on the inside of the cylinder printing plate. 10 screen angle 　　 　　The angle between the main axis of a screen and the coordinate direction for elliptical dots; for round and square dots, the angle between the main axis of the screen and the coordinate direction is *smaller*. 11 screen mesh 　　 　　A carrier for screen printing stencils with regularly arranged, identically sized apertures. 12 screen printing 　　 　　The use of the printing area is screen mesh aperture printing plate leakage method. 13 screen printing former 　　 　　A screen printing plate with openings in the printing area. 14 screen printing frame 　　 　　A framing device that secures and supports the carrier of a screen printing stencil. 15 screen printing stencil 　　 　　A closed layer on the carrier of a screen printing stencil that renders the non-printing areas impervious to ink. 16 screen printing stencil carrier 　　 　　The screen portion of a screen printing stencil that carries the printing stencil. 17 screen(mesh)volume, relative 　　 　　The total volume of the mesh divided by the total area of the mesh. 18 snap-off 　　 　　Printing process, screen printing plate and attached to the substrate ink detachment. 19 squeegee 　　 　　In screen printing, a device that forces the screen plate against the substrate and transfers the ink to the substrate through the openings in the screen plate, while scraping off excess ink from the plate. 20 squeegee blade 　　 　　The knife-like part of a squeegee that acts directly on the printing ink on the printing plate to make the ink adhere to the substrate. 21 squeegee angle 　　 　　Squeegee blade tangent direction and the substrate level or with the impression roller contact point tangent between the angle, in the squeegee knife positioning after non-stressed or non-motion state measured. 22 squeegeeing area 　　 　　Squeegee in the printing plate scraping ink running area. 23 squeegee pressure, relative 　　 　　Squeegee in a section of the stroke on the plate of the linear pressure divided by the length of the stroke. 24 squeegee side, upper side of screen printing forme　　 　　Printing ink into the screen printing plate through-hole side. 25 stencil carrier area (mesh area) 　　 　　Can be made into a stencil of the screen length and width of the product. 26 stencil area 　　 　　Covering the screen printing stencil on the image elements of the squeegee stroke in the squeegee.
