Here are some basic guidelines that will make your artwork more compatible with our sign making technologies. You should save your file as an Adobe Illustrator .AI or .EPS file. This is the most compatible type of artwork.
File types supported: .AI, .EPS, .PDF, .CDR, .DXF
All text should be converted to curves/outlines. This will eliminate any font compatibility issues. If you can't convert the text to curves/outlines, you will need to include the fonts as PC True Type or Adobe Type 1 fonts.
Guidelines for Full Color printed signs:
Any bitmap/raster artwork should be saved at full scale (the size at which it will be printed) at 300-350 DPI.
Vector Art
Vector artwork, like an Adobe Illustrator file, is made up of line segments with starting and ending points. When these line segments are put together into a closed form, you get a shape, like a square. This is the preferred type of artwork for most basic signs.
Bitmap/Raster Art File types supported: BMP, TIF, JPG
Bitmaps, or raster images, are made up of tiny dots. If you put a magnifying glass up to your computer screen or a printed page, you would see that these little dots are crowded next to each other to form the image.
A bitmap does not contain line segments. The generic term bitmap can sometimes cause confusion because it is a type of artwork, but it can also be the file extension BMP. Bitmap artwork is typically used in more complex signs and usually must be printed. Any bitmap images that will be used in a sign should be 300 DPI at full size (the size at which it will be printed).
DPI (dots per inch) or Resolution
DPI, or resolution, refers to the amount of data, expressed in dots per inch, at which a given bitmap image is stored.
If you have a bitmap that is 1 inch by 1 inch at 75 DPI, there would be 5625 (75x75) little tiny dots in it. If you have the same sized bitmap, 1x1, at 300 DPI, you have 4 times the amount (90,000 or 300x300) of dots in the bitmap. This means that the dots are smaller. Higher DPI equals better output.
