Screen Printing: A method of printing in which the ink is forced through a design on a taut screen onto the object to be printed.
Set-Ups: See make ready.
Shrinkage: Reduction of material size in any dimension.
Silicone: A polymer of organo-siloxane used as an ink additive to aid ink flow out. Also, it is used for pressure sensitive adhesives capable of withstanding extreme temperature. A polymeric material with exceptionally high repellency properties towards adhesives used extensively in the coating of release liners.
Silicone Coating: A unique polymer system, which can be a very effective, release coating.
Solvent Adhesive: Adhesive components that are dissolved in a variety of organic solvents for coating. Rubber or acrylic-based systems can be coated this way.
Splices: Is the bonding of materials to continue the printing or application process. Incorrect or insufficient splices can cause annoying liner or web breakage. Splicing material should be strong and have sufficient bond. Incorrect density of splice material extending into the margin area can cause double label dispenses when optically dispensed.
Stiffness: The rigidity of a material.
Stripping: The removal of the face material outside and around the die cut shape of a label. The matrix material is removed from the die cut label web.
Surface Tension / Dyne Level: The property, die to molecular forces, by which all liquids through contraction of the surface tend to bring the contained volume into a form having the lease area. If ink is to be compatible with a substrate, the surface tension of the ink must approximate that of the substrate.
