The most fearful thing about applying paint is the plug! This article will evaluate how the Starfire 1024 printhead eliminates the trouble of "blocking one nozzle hole and replacing the entire printhead" during the coating process.
The Starfire SG1024 printhead launched by FUJIFILM Dimatix is a high-standard printhead for industrial inkjet applications that integrates internal circulation ink supply technology, variable ink droplet technology, detachable repair structure, and high-density nozzle design technology.
Advantages of Starfire SG1024 Printhead
RediJet Internal Circulation Technology
The Starfire SG1024 printhead adopts RediJet internal circulation technology. By continuously circulating the ink inside the nozzle and the ink chamber of the nozzle panel, it can minimize the clogging caused by ink precipitation and the continuous printing fluency problems caused by the interference of ink bubbles.
Variable Ink Droplet Technology
The Starfire SG1024 printhead adopts variable ink droplet technology, which can achieve true control and application of ink droplet size, and can realize three-level grayscale printing. The grayscale level is controlled and edited by a waveform pattern matching the ink so that the printhead has better compatibility with the ink and printing effect.
Repairable Printhead Structure
The printhead is the core component of an inkjet printer and is also a consumable item. However, due to chemical corrosion, ink supply system contamination, and electronic and physical damage, the nozzle is blocked, the ink system is clogged, or the nozzle panel is scratched. Usually, when encountering these situations, users have to replace the entire printhead. The repairability of Starfire SG1024 eliminates the history of "blocking one nozzle and replacing the entire printhead".
The three areas of the Starfire SG1024 printhead that are most likely to be clogged are the piezoelectric cavity channel, the filter inside the printhead, and the nozzle plate. If these areas are clogged, the printhead can be repaired by cleaning them individually or replacing parts.
Features of Pigment Ink
Textile printing coating ink mainly contains deionized water, solvent/moisturizer, resin, and color paste. It is prepared according to a certain formula and process. Usually, the solid content of the resin in the formula can be as high as 10%, plus the solid content in the colorant of about 5%. The solid content of the entire system can be as high as 15%, which makes the coating ink easily precipitate or dry on the surface of the ink path nozzle assembly, causing permanent blockage of the printhead.
Why is Starfire 1024 Printhead Suitable for Pigment Ink?
Because the Starfire SG1024 printhead has an internal circulation system, it can effectively avoid precipitation or drying caused by the ink not flowing for a long time in the inkjet system; at the same time, the main components of the printhead can be disassembled separately for cleaning or replacement. Once the printhead is clogged, the problem can be solved by cleaning or replacing it, saving the high cost of replacing the entire printhead.
In addition, in paint digital printing, because the color expression of paint ink on fabric is relatively weak, printing dark printed images usually requires a relatively large amount of inkjet to obtain excellent color performance. Starfire printheads can achieve 7-25pl ink dot printing with its variable dot technology, which not only meets the fineness requirements of light-color printing but also meets the high-concentration color requirements of dark-color printing.
Because the technical characteristics of the Starfire SG1024 printhead match the application characteristics of the pigment ink, the Starfire 1024 printhead and the digital printing of the paint ink are a perfect combination.
1. Text and Picture Printing
Starlight 1024 printhead and pigment ink can print high-quality and high-resolution text and pictures. The nozzles inside the printhead are very small and can eject fine spray particles, making the printed text and pictures clearer and more vivid. In text and picture printing, the control of ink color and ink volume is very important. Using the characteristics of pigment ink, the color of the pigment in the ink can be well controlled and then sprayed through the printhead, you can obtain various fine effects.
2. Label and Barcode Printing
In addition to text and picture printing, the Starlight 1024 printhead and pigment ink are also ideal for label and barcode printing. This is because pigment inks have high adhesion and can print high-quality labels and barcodes on the surface of a variety of substrates. When printing labels and barcodes, there are requirements for the accuracy and speed of the printhead, and the Starlight 1024 printhead is optimized for this point.
3. Adaptability of Paper
In addition to the printing effect, the Starlight 1024 and pigment ink also have good paper adaptability. Different papers have different qualities, especially the flatness and ink absorbency of the paper, which will affect the printing effect. Using pigment ink allows you to adjust the content and color of the ink to suit different papers.
4. Environmental Protection
Compared with other inks, pigment ink has good environmental protection. During the ink manufacturing process, pigment ink does not contain toxic components such as toluene, xylene, and formaldehyde, and is less harmful to environmental pollution and health. And inkjet equipment using pigment ink can consume less energy, ensuring printing effects while reducing energy consumption and environmental pollution.
In general, the Starlight 1024 printhead and pigment ink are a very suitable combination. Pigment ink has the characteristics of high color brightness, high adhesion, and high paper adaptability, while the printhead has the characteristics of high precision, high speed, and high stability. The combination of the two can achieve very good printing results. At the same time, coating ink is less harmful to environmental pollution and health, and it also meets the environmental protection requirements of today's society.
