4A0 paper size is a large paper size that measures 1682 x 2378 mm (66.2 x 93.6 inches). It is not part of the ISO 216 paper size system, but it is sometimes used for printing large-scale graphics and technical drawings.
4A0 paper is significantly larger than the A0 paper size, which measures 841 x 1189 mm (33.1 x 46.8 inches). It provides an even larger working area for printing large graphics, posters, and other visual aids. Due to its large size, it is often used for advertising, billboards, and other large-format printing projects.
Like other large-format paper sizes, 4A0 paper is typically made from heavyweight paper with a thickness of around 130-170 gsm. This makes it strong and durable enough to withstand handling and transportation, as well as the weight of any additional materials that may be affixed to it, such as adhesives or mounting materials.
Printing 4A0 paper requires specialized large-format printers, which can print at high resolution and with accurate color reproduction. These printers use a roll of paper, rather than individual sheets, and can print at high speeds to produce large-scale prints efficiently.
In conclusion, 4A0 paper size is a large paper size that is used for printing large-scale graphics, posters, and technical drawings. It is significantly larger than the A0 paper size and provides an even larger working area for printing large visual aids. 4A0 paper is typically made from heavyweight paper and requires specialized large-format printers for printing. It is commonly used for advertising, billboards, and other large-format printing projects that require high-quality prints with accurate color reproduction.
