What kind of art is needed for screenprint?
All files should be submitted in an Adobe Illustrator vector format. If a raster file is submitted, it must have been created at a minimum of 150 dpi at the size the image will print. Please note, web art or images from the internet are never usable as is. These files are 72 dpi and cannot be up-sampled. Quark, Publisher, Powerpoint, Word, Excel, MS Paint, etc are not usable formats. Quotes on separation charges and redraw fees are recommended and available upon request.
What is the difference between a raster file and a vector file?
A VECTOR FILE is an image composed of paths. The terms outlines, curves, fonts, and spot colors are commonly used when discussing this file type. These files are usually created in Adobe Illustrator or Corel Draw. Common file extensions are pdf, eps, ai and cdr.
A RASTER FILE is an image composed of pixels. The terms resolution, redraw, and separations are commonly used when discussing this file type. These files are usually scanned, taken from the web or created in Adobe Photoshop. Common file extensions are jpg, gif, tif, bmp, png and pdf.
How file types affect which screen printing approach is used
Vector or Raster Spot Process
Art that uses half tones of a spot color to make gradients in an image but is NOT an actual photograph is usually classified as "spot process". Many corporate logos utilize this blending and shading to give depth to flat images. These files can be complicated vector graphics created in Illustrator or non-photograph raster images created in photoshop. These files can be printed on light or dark shirts but depending on the design may require some color separation fees.
