DTF film printing is a process in which color powder is transferred to fabric by high temperature and pressure. In this process, if not done properly, there may be dust problems in DTF printing. The main performance is to leave a lot of unnecessary color powder on the fabric after printing. Here's why and how to fix it.
Many DTF film on the market does not absorb ink ? Why?
The following list of some common reasons and corresponding solutions:
1. Raw material problems: poor quality, aging, damage and other factors of DTF film will have a great impact on ink absorption. Such as containing silicone oil, tar, and other harmful components will reduce the membrane surface tension, thus affecting ink adsorption, resulting in no ink absorption.
Solution: Replace the quality of the film material, and choose a professional DTF film manufacturer, to ensure the quality of the film is reliable. At the same time check storage conditions, and timely replacement of aging, damaged film.
2. Ink problem: the use of improper ink or too thick ink, often easy to leads to the printing effect is not ideal, and also reduces the film ink absorption.
Solution: Change the quality of the ink, and according to the pattern needs to adjust the appropriate ink thickness and color ratio, to avoid the consequences of poor material quality.
3. Printing parameters: printing parameters are set improperly, including ink amount, temperature, speed, etc., the adjustment of these parameters can largely ring ink attachment and print quality.
Solution: Adjust the printer parameters, debug different ink thickness, temperature, speed, find the optimal parameters, to achieve the best effect.
4. Quality management problems: Due to the lack of strict quality control, some printer manufacturers do not have strict requirements for film materials and other production links, resulting in insufficient ink absorption performance.
Solution: Strengthen the monitoring of the production link, strictly implement the quality control standards; At the same time strengthen after-sales service and quality feedback, timely correction and improvement, good product quality.
In short, in order to ensure a good DTF printing effect, we must pay attention to the selection of raw materials, printing parameters adjustment, production management and after-sales service and other aspects of the improvement.
