Our Art Team accepts the following file formats: Vector Art produced in CorelDraw 9 or below. Acceptable media PC formatted disks, CD-ROMS or Zip Disk. All Text converted to curves, paths or outlines. If we are not altering the file, a high-res tif file (300dpi) might be acceptable.
The Art criteria is so very specific to make sure that your printed information looks its best on each item it is placed on.
Bitmap VS. Vector
When working with Bitmap you are creating, changing, and deleting the pixels which are the tiny little squares of color that make up the image. Each bitmap is made up of hundreds of dots, or pixels. The disadvantage of bitmap images is that they don't scale up very well. They look very "pixilated" once you enlarge them past 300% or so. Bitmaps are resolution dependent: how good they look depends on the resolution used to display and print them.
Vector graphics are resolution independent. They are files containing coordinates, positions, curve information, and other information that are displayed as pixels when translated by a vector graphics program. The letters stay sharp and clear whatever size you choose and will still look razor sharp. The major disadvantage of vector graphics is that they are not good at creating realistic, shaded, and detailed artwork.
Usual Vector file extensions are: ai, eps, and sometimes pdf.
DPI- (Dots Per Inch)
A measure of the resolution of a printer is called DPI or dots per inch. It properly refers to the dots of ink or toner used by an imagesetter, laser printer, or other printing device to print your text and graphics. In general, the more dots, the better and sharper the image. DPI is printer resolution. DPI is not image resolution although frequently used that way.
