USEFUL DEFINITIONS AND EXPLANATIONS OF PRINTING INDUSTRY TERMS
C1S PAPER Paper coated on one side. We DO NOT print on C1S paper.
C2S PAPER Paper coated on both sides. Our 14pt and 16pt paper are examples of C2S. (AQ Coating or UV Coating are separate options and are not effected by this)
CARD STOCK Also called cover stock. Mostly heavyweight papers are called cards stock. The thickness of card stock is indicated with point sizes such as 14pt, 16pt. Some people will also refer to 100lb gloss cover as a card stock. 
CMYK The primary colors used in 4-color printing. CMYK are used to reproduce full color on the printed sheet. CMYK also called PROCESS COLOR
C: Cyan (Blue) M: Magenta (Red) Y: Yellow K: Key (Black) COATING The mixture of clay materials that are applied to paper to improve the smoothness of the paper's surface and improve ink holdout during the printing process. Examples are Aqueous coating (AQ) and UV coating. UV coating adds a gloss finish to the product and also improves the vibrancy of the printed colors. Spot-UV can be applied to selected portions of the piece, while keeping the rest a matte finish. COLOR TYPES 4:4 - 2 sided, full color on the front and full color on the back
4:1 - 2 sided, full color on the front, black on the back
4:0 - 1 sided, full color on the front, no printing on the back
DOTS PER INCH (dpi) A measurement of resolution of input, output and display devices. 300 dpi means that when printed, each square inch of your image will contain 90,000 pixels (dots), the higher the dpi (the more pixels per inch) the more crisp the printed image will be. Our electronic (digital files) have to have a resolution of at least 300 dpi. Anything less than that is considered as low resolution and may appear blurry when printed. FULL BLEED Printing that goes to the edge of all four sides of the page. MATTE FINISH A coated paper finish that is flat, not shiny like a gloss, but still keeps much of the ink from being absorbed by the paper and produces an excellent image. Matte/ Dull finish is applied to all 14pt jobs and 16pt jobs unless it is Spot UV.
PIXEL The smallest unit of a digitized image created by a digital device, such as a computer, camera, or scanner. Pixel is short for 'picture element'. The more pixels per inch the better the resolution. On computer monitors, the display is divided into rows and columns containing thousands or millions of pixels. Each pixel is composed of three dots representing the three color channels of red, green, and blue light that are necessary for creating a color image on computer monitors and television screens. Because of their small size, the pixels appear to merge, simulating a continuous tone image, but when magnified they appear to be tiny square blocks of light, as shown in the illustration. PANTONE MATCHING SYSTEM (PMS) A registered name for an ink color matching system used to compare, match and identify specific colors. To do so we use a pantone book. It contains pantone colors, cross referenced to their closest CMYK values. RESOLUTION The measurement of output quality expressed in pixels (dots) per inch on a computer monitor or dots per inch on printed media. For example, a monitor displaying a resolution of 800 by 600 refers to a screen capable of displaying 800 pixels in each of 600 lines, which translates into a total of 480,000 pixels displayed on the screen. When referring to printed media, a 300 dpi (dots per inch) printer for example, is capable of outputting 300 dots in a one-inch line, which means that it has the ability of printing 90,000 distinct dots per square inch (300 x 300). UV COATING A liquid coating applied to the printed piece, which is then bonded and cured with ultraviolet light. This coating is used to provide a protective coating to the printed image. Please note that you CAN NOT write or imprint on a UV coated job. (exception: A Silver Metallic 'Sharpie' will write on UV Coated products.) |
