DTF Film Why Shake Powder Is Not Clean?

DTF Film Why Shake Powder Is Not Clean

DTF film, one of the DTF printer’s essential consumables, is essential to the DTF printing result. On the other hand, improper use technique or other circumstances during the daily use process might cause powder residue on the DTF film, which will negatively impact the printing effect.

We will address the main causes of the unclean DTF printer shaking powder today. Together, let’s learn.

The DTF powder shaking machine actually has a simple working principle: it just needs to sprinkle, shake, and dry powder.

After evenly sprinkling the hot melt glue powder over the hot stamping pattern, shaking off any excess, and drying the hot stamping pattern with the hot melt powder, the process is complete. We will examine the causes of the shake powder’s unclean nature after comprehending the machine’s fundamental operating procedures.

Issue with ink concentration

An excessive amount of hot melt powder may get stuck on the pattern’s edge when powder is shaken, causing the ink flow phenomenon—which is the oil and water of the white ink seeping outside the edge—to occur more easily if the concentration of white ink is too low and the surface moisture is high. In order to detect this phenomenon, the DTF film usually needs to be freshly printed and not have hot melt powder thrown on it too soon. Therefore, it can be concluded that the ink is the issue if there is a water stain surrounding the print film pattern before powder.

Solution: You can make the condition better by replacing the ink or pre-drying it before dusting. Sublistar consumables can be used with confidence because they have undergone extensive testing and nearly no comparable issues have arisen.

DTF film quality issue

If the sticky powder issue is resolved using identical consumables and production conditions after a new hot stamping film is installed, then there’s a good chance the hot stamping film is subpar, unqualified, or has insufficient compatibility with ink.

Solution: This issue can be resolved by switching out the relevant heated film. Alternatively, this issue can be mostly avoided if you select a Sublistar DTF printer and its associated consumables.

Since we shall undergo numerous tests before to the manufacturing in order to guarantee flawless results. Furthermore, Sublistar offers a variety of distinctive film kinds that may fully satisfy customers’ customized small-batch production needs.

Problems in preserving hot melt powder

No matter how high-quality the hot melt powder is, it will cake if it is used past its expiration date or if preservation is neglected, leading to moisture buildup. This will cause sticky powder phenomena while printing, and the pattern edge will also clearly show glue edges.

Solution: Either provide moisture to the hot melt powder or bake the damp powder gently before sifting it into the powder shaking machine. Currently, the Sublistar DTF printer has been improved, and the powder shaking machine’s preheating function has been added. This enables the hot melt powder to flow smoothly in low-temperature or slightly humid environments and completely removes water, maximizing the hot melt powder’s potential.

Problems with humidity

The excessively high air humidity caused by the weather will cause the white ink to dry slowly. Additionally, the wet white ink will lead the pattern’s edge to stick to an excessive amount of hot melt powder, resulting in the formation of a glue edge and a powder edge.

Selecting a printer and a powder shaking device with a pre-drying mechanism is the answer. Alternatively employ a dehumidifier or air conditioner and regulate the printing environment to maintain an air humidity level below 65%.

Problem with electrostatics

If the machine is not grounded, sticky powder is a common problem and the static electricity of the DTF film increases in dry weather. By connecting the machine, the ground wire can be improved.

DTF device issue

Should the aforementioned factors be disregarded and there remains unclean hot melt powder on the hot stamping film, it could indicate that the powder shaking machine’s quality is subpar.

A top-notch white ink hot painting shake powder machine typically operates in five steps: circulating vibration powder for pre-drying – discharge the pounding powder – collecting materials; drying in a suction tube

A preheating plate located in front of the powder sprinkling device on the Sublistar DTF powder mixer significantly reduces the amount of powder residue outside the hot film pattern.

Utilizing an automatic powder bin that has been preheated will increase the adhesion between the powder and the fabric, making the pattern naturally more solid. This will also ensure that the hot melt powder is distributed more uniformly during the subsequent pressing process. Additionally, the powder can lessen the likelihood of powder aggregation in this way. Following that, the shake powder takes on a release beating mode. The intensity of the shake powder can then be changed based on how much cleaning is required.

The oven’s independent heating, more even drying, and effective prevention of issues such oil return dampness and pressing the pattern will prevent offset printing issues from arising.

With its vacuum suction and mesh belt feeding mode, the feeding process is easy to operate and won’t waste any film. Features include an automatic induction winding, a tension receiving system, independent cutting at any moment, and more convenient proofing. Touch screen integrated control is made possible with a multilingual control screen, simplifying the usage of every function.

As a result, there are numerous justifications for DTF printing film shaking powder, which is particular and determined by the real circumstances throughout the printing process. If you have any additional inquiries concerning the printing film, please get in touch with us.
