Screen printing: the printing plate is in the form of a mesh, and the ink on the printing plate is squeezed by the squeegee to leak from the through hole of the layout to the substrate during printing.
Porous printing: A printing method in which the graphic part of the printing plate can be printed on the substrate through ink leakage. Divided into screen printing, transcription, typing wax and hollow printing.
Electrostatic screen printing: Use electrostatic charge to make toner adsorb on the substrate through the wire mesh.
Typewriter stencil duplicating: using a typewriter to make stencils of characters on stencils, and then ink printing on the stencils.
Curved surface screen printing: A method of screen printing on the curved surface of a cylindrical container or cone.
Stencil clogging: The mesh of the screen printing plate is gradually clogged due to the drying of the ink, resulting in printing failure.
Stencil printing: Scribing graphics and texts on wood chips, cardboard, metal or plastic sheets, and hollowing them out to make a hollow plate. The ink is attached to the substrate through the through holes by brushing or spraying.
Mimeograph: drawing with a stylus or other means on stenciled paper, and then applying ink to print on the stenciled paper.
Jagged outlines: Due to the influence of the mesh of the screen, the edges of the graphics and text appear zigzag, resulting in unclear imprints on the substrate.
Flake off screen: The process in which the screen bounces off the substrate when the squeegee leaves the substrate when printing with a screen distance.
Stretching: the work of stretching the wire mesh tightly on the mesh bar.
ink distribution: While ensuring that the ink does not leak out of the screen, the ink is evenly scraped from one end of the screen to the other end.
Opaquing,stopping: It is the process of filling ink into the mesh. Ink release The process by which part of the ink is released from the screen onto the substrate.
Snap-off: During the printing process, the screen printing plate is separated from the ink attached to the substrate.
Flood coat(flooding, flood pull, flow coat) : Fills the through holes of the screen printing plate with ink before the printing operation.
Width of ink rest area: the distance between the ink scraping area and the screen printing frame.
Through printing: A printing method in which the printing area of the printing plate is ink-permeable rather than the printing area is ink-impermeable.
Theoretical ink volume: the product of the screen thickness and the percentage of open area.
Squeegee relative pressure: The linear pressure of the squeegee on the printing plate during a certain stroke divided by the length of this stroke.
Squeegee side, the upper side of screen printing forme: The side where printing ink enters the through hole of the screen printing plate.
Printing side(lower side): The bottom surface of the screen printing plate, that is, the side where the ink is in contact with the substrate.
Screen plate: The printing layout is mesh-like, a stencil printing plate composed of a screen template, a screen and a screen frame.
Cylinder stencil: a cylinder-shaped metal screen printing plate.
Direct and indirect combination screen plate: A screen printing plate made by applying scraping photosensitive glue and adhering photosensitive film on the printing plate support.
Direct photographic screen plate: A photographic screen printing plate that is directly printed on a screen coated with photosensitive glue.
Indirect photographic screen plate: A screen printing plate made by transferring a sun-dried photosensitive film to a screen.
Hand etched stencil: Use a crayon to draw graphics on the printing plate support, and apply a hydrosol, and then use a solvent to remove the part drawn by the crayon on the back to form a screen printing plate.
lacquered screen plate: A water-insoluble varnish applied to a screen plate to strengthen the printing plate for printing with corrosive and non-solvent inks.
lacquer film engraved stencil: A stencil in which a lacquer film is hand-engraved to make a stencil and then transferred to a web.
Photo-emulsion for screen plate: A kind of glue used to scrape on the printing plate support and produce a screen printing plate through photochemical reaction.
Photosensitive film: a photosensitive material used for indirect screen printing plates.
Post-coat lacquer: Apply a special varnish to the prepared screen printing plate to enhance the corrosion resistance of the ink.
Pre-coated lacquer: The supporting body of the printing plate is coated with a special varnish, which is convenient for scraping the photosensitive adhesive layer in the future.
Template: A sealing layer made of photosensitive adhesive wax, wax sheet or other materials attached to the screen so that the blank part does not leak ink.
open stencil area: the sum of all image areas on the screen printing stencil.
Screen stencil: A sealing layer composed of adhesive film, diaphragm or other materials, attached to the support of the screen plate, so that the non-graphic part does not leak ink.
Thickness of screen printing forme: the distance between the upper and lower sides of the screen printing plate.
Stencil film thickness: The thickness of the stencil material made into a film.
Stencil area: the product of the length and width of the rectangle formed by the squeegee stroke covering the image elements on the screen printing template in the direction of the squeegee.
open mesh area percentage: The ratio of the area of all mesh holes of the screen to the total area of the corresponding screen, expressed as a percentage.
Stencil carrier area (mesh area): The product of the length and width of the screen that can be made into a stencil.
Thickness of stencil build-up: the thickness of the stencil layer attached to the stencil carrier, that is, the difference between the thickness of the screen printing plate and the thickness of the stencil carrier.
Hand-cut film: It is used for hand-engraving printing plates or making sheets for printing negatives.
Screen stencil hardening treatment: use chemical and physical methods to treat the solid seal layer on the screen printing plate to achieve higher printing strength.
Screen printing stencil carrier: the screen part of the screen printing plate that carries the printing template.
Through printing forme: a printing plate that is ink-permeable in the printing area and impervious to ink in the non-printing area.
Volume of the stencil, relative: The volume formed by the through-holes on the stencil that hold the printing ink.
