If you have a large scale printing job then a roll to roll printer is probably perfect for you. Roll to roll printers are available in both UV and Inkjet format depending on the type of ink you wish to use. Roll to roll printers would have a roll of blank media on one roll. The media is then fed from that roll through a printing head and in the cases of UV printers under a UV light. The printed product is then fed back onto another roll. Since both the blank material and the printed material are on rolls it takes up a heck of a lot less space than if it was stacked sheet by sheet. Having the media on a roll also allows you to determine the length of the printed sheets since they are not pre cut to a specific sizing. Please ensure to read all the instructions that come with your printer to ensure that you are purchasing the proper supplies for it as well as to ensure that you are using it correctly.
