We require a vectored artwork file for the purpose of imprinting your logo on a promotional product, or embroidering it on a clothing product. Vectors are a combination of shapes and or lines that make up a drawing. Each individual line or shape is made up of either a vast collection of points interconnecting all of them or just a few control points that are connected using Bézier (Pronounced bez-ee-ay) curves. Vector drawings can usually be scaled without any loss in quality. This makes them ideal for company logos, maps or other objects that have to be resized frequently. Vector drawings are usually pretty small files because they only contain data about the Bézier curves that form the drawing. EPS file format is often used to store vector. There are hundreds of applications on the market that can be used to create or modify vector data. In prepress, the most popular programs are Adobe Illustrator and Corel Draw. PDF: (Portable Document Format) Is a versatile file format that can contain just about any type of data including complete pages. If you or you or your artist is knowledgeable in the area of vectors you may send us your Ai or illustrator PDF. If you choose to send us an Ai or PDF file our artist will need to verify that it’s truly a vector. PICT: file format that can contain both bitmap and vector data but that is mainly used on Macintosh computers and is not very suitable for prepress. PSD: the native file format of Adobe Photoshop (which can also contain vector data such as clipping paths) If you’re your artwork is in any of the above artwork it will need to vectored. We can provide that service at a minimum cost. Why we don’t use Bitmaps Bitmap images (scans, digital photos, web images, and the like) are created from a series of tiny colored squares, called pixels, that when viewed at 100% produce a seamless image similar to a photograph. A pixel is a variable-size unit meaning that you can fit a number of pixels within an inch, eg 72 pixels means 72 pixels fits into an inch to produce an image. The more pixels used to create the image, the higher the quality. A scan made up of 300 pixels per inch (ppi) will look much better than the same image at 72 pixels per inch set at the same dimensions. Low resolution images (72ppi – 200ppi) will look jagged and grainy when printed on a press because there is simply not enough information, in terms of pixels, to create a quality image. Source.
