Description

Technical Field

[0001] The utility model belongs to the field of printers, relates to a thermal printer, and in particular to a double-sided printer for advertising banners. Background Art

[0002] The existing method for making advertising banners is to heat the ribbon through the print head of the banner printer so that the pigment on the ribbon is transferred to the banner. However, this method for making advertising banners has the following disadvantages: 1. The ribbon includes a PET film for carrying pigments, and the used PET film is not easy to degrade and needs to be harmlessly treated. 2. During the printing process, the pigment on the ribbon is consumed and transferred to the corresponding area of ​​the banner. However, there is unconsumed pigment on the ribbon, which causes great waste. 3. After the pigment on the ribbon is transferred to the banner, the image presented on the banner is not firm and is easy to fall off the advertising banner after being washed by rain. 4. The main material of the original ribbon is wax-based, which will crack in a low temperature environment. Therefore, the application document with application number 2023118460615 discloses an advertising banner and a production method to solve the above problems. On this basis, when a single-sided printer prints such a new type of banner, there will be a color difference between the two sides of the banner after printing. Specifically, the printed surface of the banner is bright in color, while the back is dull in color. In order to make the printed advertising banner more beautiful, a new printer capable of printing on both sides of the banner is urgently needed. Utility Model Content
