It is not always necessary to scale your artwork. Scaling artwork can help to keep the file size manageable. Here are a few things to keep in mind if you are scaling your artwork.
Vector Art
Grand4mat is able to print outdoor banners as large as 150ft x 16ft, however most software is not able to produce an art board larger than 228". Adobe Acrobat and other PDF readers / converters are only able to view a maximum file size of 200", resulting in a loss of artwork. For this reason, it is recommended to submit files at a smaller scale than the ordered size.
Raster Art
Raster files are calculated by pixels rather than inches. The pixels are converted to inches based on the resolution of a file. The equation for the conversion is (pixels divided by dpi = inches). Raster files have a limitation of 30,000 pixels. A file that is 30,000 pixels set at 150 dpi will be 16' (200"). If your artwork is more than 30,000 pixels, we recommend dropping your dpi or scaling down your artwork.
Resolution &, Scale Charts
Grand4Mat is fully automated and expands/constricts file sizes to the ordered size. Resolution varies based on the substrate and ink used to print the final product. If your artwork needs to be scaled, we recommend using the following information as a basic guide:
Outdoor Banners:
Full scale at approximately 100dpi
Half scale at approximately 200dpi
Quarter scale at approximately 300dpi
Note: Banners larger than 15 feet will print below 100dpi
Flags:
Full scale at approximately 150dpi
Canvas:
Full scale at approximately 250dpi
Coroplast and Adhesive Vinyl
Full scale at approximately 200dpi
Foamcore:
Full scale at approximately 250dpi
PVC:
Full scale at approximately 250dpi
Indoor Banners, Car Magnets, Floor Graphics and Large Posters:
Full scale at approximately 300dpi
Table Runners:
Full scale at approximately 200dpi
Adhesive Vinyl:
Full scale at 100 dpi. vector artwork is preferred
