BASIS WEIGHT The weight in pounds of a ream (500 sheets) of paper cut to a given standard size for that grade; e.g., 500 sheets 25x38 of 80lb. coated book paper weighs eighty pounds. BLEED An image or printed color that runs off the trimmed edge of a page. Bleeding one or more edges of a printed page generally increases both the amount of paper needed and the overall production cost of a printed job. Bleeds are created by trimming the page after printing. BLIND EMBOSSING Stamping raised letters or images into paper using pressure and a die, but without using foil or ink to add color to the raised areas. Braille is an example of blind embossing. COATED PAPER Paper with an outer layer of coating applied to one or both sides. Coated papers are available in a variety of finishes, like gloss, dull, and matte. They tend to have good ink holdout and minimal dot gain, which can be especially important for recreating sharp, bright printed images, black and white halftones, and four-color process images. FINISHING Preparing printed pages for use. Most printed jobs require one or more finishing steps, such as trimming, folding, or binding. LINES PER INCH The number of lines in an inch, as found on the screens that create halftones and four-color process images. The more lines per inch, the more detailed the printed image will be. MAKE-READY All the activities involved in preparing a printing press for a print run, such as setting the registration, balancing the color, and adjusting the plates and blankets for paper thickness. OPACITY A measure of how opaque a paper is. The more fibers or fillers a paper has, the more opaque it is, and the less it allows "show through" of the printed image on the back side or on the next page. Opacity isn't always determined by thickness or weight; a thinner paper may have more opacity than a thicker paper if opacifying thickeners are used. SELF COVER A booklet having a cover made of the same paper as the inside or text pages. UNCOATED PAPER Paper that doesn't have a coating. Uncoated papers are manufactured in a great variety of finishes, colors, and weights, and offer the versatility needed to meet the creative and practical demands of most print jobs. © Copyright 2000, The Press.
