Sra3 320 x 450mm , for printing A3 with bleed
SRA3 paper measures 320 mm x 450 mm (12.6 in x 17.7 in). It is primarily used in the printing industry for producing larger formats, allowing for bleed and trimming of artwork. This size is often utilized in commercial printing, posters, and other high-quality print materials.
SRA3, or "Syndromic Retinal Atrophy 3," is a genetic disorder characterized by progressive vision loss due to retinal degeneration. It is associated with mutations in specific genes that affect the structure and function of retinal cells. The condition is often inherited in an autosomal recessive pattern, meaning both copies of the gene in an individual must be mutated for the disease to manifest. Symptoms typically appear in childhood or adolescence and can lead to significant visual impairment over time.
