What file format is best for vector graphics?
We most commonly use EPS or AI files but other vector formats include CDR, DXF, FS and sometimes PDF. If using EPS or AI file please save it to a version 10 or earlier since later versions aren’t compatible with our design software. Additionally please make sure all fonts are converted to outlines (also ‘called converted’ to curves depending on your design program). If you are unsure how to convert the file just give us a call and we would be happy to walk you through the process. Please not that embedding a raster graphic into an EPS or AI file does not change it to a vector graphic.
For work with .ai files utilize adobe illustrator damaged file repair?
