| Flowing Ink | 1. There are powder impurities or indentation and fracture marks at these locations, and these areas are prone to ink leakage. | If the overall ink absorption effect is slightly poor and ink leakage occurs, you can try the following methods: 1. Reduce the proportion of white ink and appropriately decrease the amount of white ink; 2. Increasing the temperature of the printer's heating plate can also improve the throughput rate; 3. The heating function of the heating plate can help activate the ink and reduce the ink leakage phenomenon. |
| The shaking did not clean the powder thoroughly | The weather is humid, with high humidity and strong static electricity. If there is a problem with the unevenness of the pattern edges, it is necessary to check: 1. Whether the environmental humidity is too high or the temperature is too low, 2. Whether the force of the powder shaker is insufficient, 3. Whether there was an interval of too long time without powder spreading after printing and the glycerol was allowed to diffuse, 4. Whether there is ink flying from the print head. | If it is found that the powder is not evenly distributed on the pressure wheel or there is a large area of blank spots that are not evenly distributed, it is likely due to static electricity or the powder being damp or too fine. In such cases, appropriate measures should be taken. Generally, raising the temperature of the heating plate after printing and the heating plate of the powder distribution machine can help reduce the phenomenon of uneven powder distribution at the edges. |
| Candied yam perforation | The high-temperature short-time baking caused the water and glycerol in the ink to violently boil and evaporate, thereby expanding the pores of the coating and the film layer. | It is better to use medium-fine powder as the main ingredient, with only a small amount of coarse powder mixed in, or even no powder at all. If the baking machine is of good quality, it will achieve the best effect by baking in two stages - a low-temperature section and a high-temperature section with a longer travel distance. It can gradually and thoroughly dry out the oil and water, melt the glue, and avoid intense reactions. The baked film is both flexible, elastic, smooth, and has good dryness. If the baking machine has slightly inferior initial conditions, it is advisable to make good use of the function of preheating the cutting board to heat it in advance and evaporate some moisture to reduce the burden. First, dry it a little and then sift the powder. |
| Oil return or moisture regain | The patterns after baking or those that have been transferred by adhesive will develop oil bubbles and water droplets. | This is because when baking the glue, it is not baked thoroughly. The water and glycerin in the printed ink, or the moisturizers, cannot be completely dried or evaporated, thus causing the phenomenon of back-sweating. For single sheet operation plates, it is best to bake them at around 120 degrees for a long time to ensure thorough baking. For continuous baking of powder, the length of the powder baking machine is a limitation. Therefore, it is advisable to raise the temperature in front of the baking machine and appropriately increase the temperature to allow the water, glycerin, or moisturizers to evaporate earlier, which can also be helpful. |
| Foil transfer powder loss | After stamping, a coating is adhered to the blank area around the pattern. | This is because the heat pressing pressure was too high, which caused the ink-absorbing layer on the film to be damaged and peel off, or the surface coating of the fabric was prone to stick to the coating layer. Generally, as long as the temperature and heat pressing time meet the requirements for adhesion, the pressure can be reduced as much as possible. This can be easily solved. |
| Pattern ghosting, misalignment, or paper slippage | This is because the design of the equipment's membrane-stepping process is not perfect, and it fails to fully meet the usage requirements of a single mask. | The smoothness on the back of the mask interferes with the operation of the device. Usually, such a device can only be used with double masks. Once there is friction caused by the matte finish on the back, it will immediately return to normal. |
| Upturned edge | The temperature is too low or the stamping time is too short. | Adjust the temperature or duration of the heat stamping appropriately |
| The adhesion after foil stamping is poor | Each membrane has a different formula, the principle of the pressing and ironing machine is different, and the usage duration and methods are also different, which can lead to discrepancies between the instrument readings and the actual situation, as well as issues with the uniformity of the powder. | Make the following adjustments: 1. Powder application: It is recommended to use medium powder or a finer grade to ensure a better adhesion. 2. Pressing machine: If it is an air pressure pressing machine, there will be discrepancies in the temperature, pressure, duration and time indicated by the instrument. It is recommended to adjust the pressure and temperature. |
