Silverprint - A proof that is made of the negative film to ensure that all elements are accurate and in correct position before the plate is made. Sizing - Treatment of paper which gives it resistance to the penetration of liquids (particularly water) or vapors. Skid (also pallet) - Wooden platform that supports piles of paper during shipping and storage. Skids usually accommodate from 2500 to 4000 pounds of paper. Slit - To cut printed sheets or webs into two or more sections by means of cutting wheels on a press or folder. Slur - A smearing of ink that occurs in printing when there isn�t enough pressure on the blanket. Soft Dot - Halftone dot with a weak fringe density or halo surrounding a solid core. Soft Proof - A proof that is viewed on a color-calibrated video monitor as opposed to a hard proof on paper. Solid - Any area of the sheet receiving 100 percent ink coverage. Specs - Complete and precise written description (or specifications) of features of a printing job such as type size and leading, paper grade and quantity, printing quality or binding method. Spine - The back of a bound book connecting the two covers. Also called backbone. Spiral Bind - To bind using a spiral of continuous wire or plastic looped through holes. Also called coil bind.
