Graphic Designer Terminology - Raster VS. Vector, Resolution, DPI, PPI, Halftones & Linked Images11/13/2018 Ever get confused with Graphic Designer terminology? If words like raster, vector, resolution, DPI, PPI, halftones or linked images cause you anxiety? Look no more. Watch my latest video or read the information below and instantly feel enlightened in the topics listed above... Raster artwork is any digital art composed of horizontal and vertical rows of pixels. As a result, when raster images are enlarged, the image quality diminishes significantly. Typical raster file types include .psd, .tif, .jpg, .gif, and .bmp. Vector art is created using vector illustration software programs, such as Adobe Illustrator or Corel Draw. These programs use mathematical equations and geometric primitives (points, lines, and shapes) to create art that is clean, camera ready, and can be scaled infinitely, without any loss of quality or fidelity. Resolution refers to the amount of visual detail contained in an image. ... In printing terms, a higher dpi means that the printer will place more dots of ink for every inch of artwork. For most artwork, 300 dpi is preferred. Most printers produce excellent output from images set at 300 ppi. Though the terms DPI (dots per inch) and PPI(pixels per inch) both describe the resolution (or clarity) of an image, they're not the same thing. PPI describes the number of square pixels that show up in an inch of digital screen (usually between 67-300). DPI, on the other hand, is a printing term referring to the number of physical dots of ink in a printed document. Halftones are defined as a reproduction of a photograph or other image in which the various tones of gray or color are produced by variously sized dots of ink. Think shades of gray in a photograph or an image printed by a method that creates many small dots such as off set printing. When you place an image into Illustrator, you can choose to link or embed the image. Below I lay out what each means, list their pros and cons, and show you how to perform each one. Linked images remain independent of the Illustrator or InDesign file. Pros
