Raster format type uses pixels placed in a grid. This graphic file format images described as a matrix of dots - that is, pixels are located by exact addresses, rather than by their relation to other pixels.)

Raster file formats are used with photographic, scanned, or native cameras images. Typically seen in the photo, fine art, GIS, and signage markets.

Some examples of ONYX supported files include:

• TIFF (8 and 16-bit)
• True L*a*b*
• RGB (24 bit)

It's all about viewing distance - balance the file size with the output application to avoid unnecessary processing and long RIP times:

• Photo Size - 200-240 PPI
• Page Size 12" X 18" / 18" X 24" - 150 PPI
• Poster Size 24" X 36" / 36" X 48" - 100 PPI
• Banner Size / Large Prints - 100 PPI
• Maps / Line Drawings - 300 to 600 PPI
