 | Label | | The functional portion of a pressure-sensitive construction comprising the face sheet and adhesive, die cut into various shapes. |
| Lacquer | | A solution or suspension of one or more materials in volatile solvents capable of forming a protective and or decorative film or a film with special surface properties, after the solvents have evaporated. |
| Laminate | | A web material formed by bonding two or more materials together. |
| Lap Splice | | A splice made by overlapping the ends. |
| Laser | | The acronym for light amplification by stimulated emission radiation. The laser is an intense light beam with very narrow band width that can produce images by electronic. It makes possible imaging by remote control from computers or facsimile transmission. |
| Laser Printing | | A non-impact electrophotographic process utilizing a laser beam to scan the surface of the drum creating a latent image which attracts toner. The toner is then transfer fused into the print surface. |
| Latex | | An emulsion of rubber or resin particles dispersed in an aqueous medium a natural synthetic elastomeric dispersion in a aqueous system. |
| Latex Paper | | Impregnated Paper / Saturated Paper. Paper manufactured by two major processes: 1) the latex is incorporated with the fibers in the beater to formation of the sheet; 2) a performed web of absorbent fiber is saturated with properly latex. The papers are characterized by strength, folding endurance, resistance to penetration by water, flexibility durability and resistance to abrasion. |
| Lay Flat | | An adhesive material with good non-curling and non-characteristics. |
| LCJ | | Laser Copy™ Jet |
| LD | | Low Durabilty |
| Legging | | Legging can be exhibited when unwinding a roll, or in the end-use application. When peeling back adhesive backed products, one can witness the adhesive bonding to both the end use, and laminated materials. When this occurs, the adhesive strings between both materials upon removal. In an end-use application, legging can be the result of Plasticizer migration. In a roll of tape, legging can be the result of an inadequate release system. |
| Letterpress Printing | | Printing process in which ink is applied to a surface from portions of rigid printing plates or type. |
| Lifting | | Refers to the condition when a tape, on its own accord comes away from the surface to which it was applied. |
| Liner Side | | In roll form it is referred to that side of the roll protected by the release liner. |
| Luster | | Gloss of a finish. |
