Further Information

The dimensions of the RAW series paper sizes are defined by the ISO 217:1995 paper size standard. The format consists of the RA series and the SRA series. RA stands for ‘Raw Format A’, and SRA stands for ‘Supplementary Raw Format A’. The untrimmed raw paper is used for commercial printing, and as it is slightly larger than the A series format, it allows the ink to bleed to the edge of the paper, before being cut to match the A format.
