Almost everyone has a graphic in mind when they order a sign.  The main problem that we encounter is that the graphic file that is sent is often of relatively poor quality.  Although we do have the ability to scale graphics up, we can only go so far before the picture loses it's detail.  Ideally, a graphic would be supplied in a vector format as opposed to a raster format. Raster images are often called bitmap images.  These images are measured in dpi, or "dots per inch".  These are great as long as the image is at the correct dpi for the size that is being printed.  For example, if you want to print an image at 12" x 12", and the requirement is 150 dpi, you would need an image that has a total resolution of 1,800 x 1,800 (150 x 12).  If you need to provide an image in raster format, keep this in mind: JPG files lose quality each time they are saved.  If you provide a file in JPG format, it is best provided directly after being pulled off of it's native device (camera, scanner...).  Other raster file formats include: BMP, TIFF, PNG and TGA.  Here at Front Range Vital Signs, we recommend that all artwork be sent to us at the highest resolution possible with a minimum of at least 150 dpi at the size that is to be printed. TIFF images would be our preferred file format, but we can work with any of the formats mentioned. If possible, a vector file would be preferred.  A vector graphic is a set of mathematical equations that determine the lines/shapes that make up the image.  Since these aren't fixed pixels, they can be scaled to any size without losing quality. Vector files are created in programs like Adobe Illustrator. The vector formats that we can use include: AI, EPS and PDF (not all EPS and PDF files are vector files...make sure to save them as 100% vector files). It is possible for us to convert some raster graphics into vector graphics.  This does however, take some time, and can add on to the cost of your sign.  The good news is that the conversion would only need to happen once.  We would keep the graphic on file to be able to use for any future signs you may need.
