Choose quick-drying sublimation transfer paper according to the printer?

As one of the core of the sublimation transfer process, printers are currently divided into three categories according to printing speed: low-speed, medium-speed and high-speed machines. There is actually no particularly clear definition between low-speed and medium-speed machines. Generally, printers with a full-width printing speed of less than 1 m/min are classified as low-speed machines; those with a printing speed of 1 to 10 m/min are classified as medium-speed machines; and those with a printing speed of more than 10 m/min are classified as high-speed machines. 1. The demand for sublimation transfer paper for low-speed scanning printers: Low-speed printers such as Mimaki JV33, Muto 1604, and Yingweitu have higher printing precision, and the printer structure is generally equipped with a paper pressing wheel. When printing with high inkjet volume, the paper will swell and deform after absorbing ink because the paper stays in the nozzle movement area for a relatively long time; and because of the pressure restraint of the paper pressing wheel on the paper, the paper will produce obvious prismatic arches after deformation, which is easy to touch the nozzle and destroy the printed pattern. Therefore, for this type of printer, the paper is required to have small wet deformation and the transfer paper coating must have strong ink carrying capacity.

2. The demand for thermal sublimation transfer paper for medium-speed printers: Medium-speed printers are similar to Italian MS-JP4, MS-JP7, Tianjin Licai MICOLOR 5816, etc. Compared with low-speed machines, the printing speed of such machines is several times higher. Generally, there is no paper pressing wheel, and the paper operation is completely adjusted by roller tension. The printing speed is significantly faster. Although the drying interval is lengthened, it is obviously not enough compared to the speed increase, so the paper drying speed is required to be higher.

3. The demand for thermal sublimation transfer paper for high-speed printers. High-speed printers currently mainly refer to single-channel printers, such as One-Pass or Single-Pass printers that we often hear. The most obvious feature of this type of printer is that the nozzles are fixed in multiple rows and do not move during printing. Printing is completely based on paper movement. The printing speed is very fast, which can reach 30-80m/min, and the drying channel length is generally more than 10 meters. In addition, the paper is adhered to the surface of the guide belt in the printing channel.

The requirements of this type of printer for paper are mainly manifested in the following points.
a. Good flatness: Most of the coated paper has the phenomenon of paper warping after high-temperature baking, which is commonly known as "poor bending resistance" in the industry. The drying tunnel of high-speed printers is longer, and the high-temperature baking time of paper in the oven is relatively long, so the paper must have good flatness after high-temperature baking.
b. Fast drying speed: Although the drying tunnel of high-speed printers has been lengthened, due to the fast running speed of paper, heat source restrictions, factory restrictions, etc., the paper itself still needs to have fast drying characteristics.
c. The peelability of the back coating of the paper should be appropriate.
d. The paper should be thin: Due to the high speed of the machine, thin paper is more conducive to large roll printing and high-speed thermal transfer, and can also greatly reduce costs.
