How to judge the performance of sublimation paper?
Jun 01, 2022
Sublimation paper is an important consumable in the dye sublimation process. The performance of the transfer paper directly affects the effect of the transfer pattern, and poor quality transfer paper will also cause huge losses in production.
How to judge the performance of sublimation transfer paper is a problem that many customers often face when choosing transfer paper.
We can judge the performance of sublimation paper from the following aspects:
Transfer rate
The fundamental performance of transfer paper is transfer rate, which is also one of the most highly regarded by the majority of clients. The performance of the transfer paper may be immediately reflected in the transfer rate. Following transfer, the sublimation of the sublimation ink is mostly reflected in the transfer rate. There is little ink left on the paper surface after transfer, indicating a rapid transfer rate. The brighter the color of the pattern on the substrate, under the same circumstances, the higher the sublimation transfer paper's transfer rate.
2. Dye penetration
The dye penetration phenomenon of sublimation transfer paper refers to the phenomenon that the coating on the surface of the transfer paper has limited dye-bearing capacity, and part of the ink penetrates into the base paper through the coating. Under normal circumstances, serious dye penetration will directly affect the quality of the transferred pattern, which may cause the pattern to be light or uneven after transfer.
3. Drying speed
The time needed for the dye on the paper surface to fully dry after the transfer paper is ink-jet printed is referred to as the drying speed of sublimation transfer paper. The drying standard is to softly touch the printing paper's surface with the back of your hand, making sure that the back is clean of ink stains. The printing efficiency is directly impacted by the drying speed. The requirements for the drying speed of transfer paper have increased along with the ongoing improvement of dye-sublimation digital printers, which has also boosted printer speed. The patterns on the paper surface are readily worn when the transfer paper's drying speed is not fast enough to keep up with the printing pace.
4. Flatness of paper
The flatness of the paper surface directly affects the printing process. The transfer paper with poor flatness is prone to friction with the inkjet head in digital inkjet printing, which not only affects the print quality, but also easily damages the nozzles and shortens the service life of the equipment.
5. Warpage
The warpage phenomenon results from an uneven rate of expansion and contraction between the coated and base paper surfaces. This can cause issues with the feeding of printer paper, wrinkles that need to be rewound after printing, misalignment of transfer patterns, and other issues that impede regular production. The negative impact of warping on production is lessened by the overall anti-warping ability of high-quality sublimation transfer paper.
