1. Selection of printing process: The selection of printing process directly determines the selection of digital printing machine type. For clothing fabric printing, whether to choose transfer process or direct injection process has a directional and decisive role in the selection of digital printing machine.
The transfer process has a small investment and high printing precision, but the applicable fabrics are limited, mainly suitable for chemical fiber fabrics.
The direct injection process has a wide range of fabric applications, and can be applied to linen, silk, wool, cotton, polyester, nylon, and modal, but it requires sizing, steaming, washing and other processes, and the investment is relatively large. The fastest direct injection textile printing machine is the Kyocera nozzle (one nozzle is about more than 40,000 yuan), followed by the Starlight 1024 (more than 20,000) nozzle, which is a high-speed nozzle. The common medium-speed nozzles are: Ricoh G5, Seiko, Konica 1024i, etc. Thermal transfer has high precision, small investment, and no pre- and post-processing is required, but it is not applicable to many fabrics. It is mainly used in chemical fiber fabrics. Generally, Epson nozzles are used, which are very slow and suitable for printing samples.
2. Choice of precision: Enterprises can choose the equipment with the printing precision of digital printing machines according to the materials of the items they make. When choosing printing precision, it should be noted that the higher the precision, the better, because precision and efficiency are two opposing factors. If the precision requirement is higher, the efficiency is lower. It is also necessary to consider from the customer's requirements whether the selected textile printing machine can meet the customer's precision requirements. At the same time, the higher the precision, the slower the efficiency. While pursuing high precision, don't forget whether the printing speed can meet the standard.
3. Ink selection is the key: There are generally three points in the selection of printing ink. 1. Selection of printing ink color. According to customer needs and fabric type, you can choose four-color ink, six-color ink, eight-color ink, etc. Generally, the more ink colors, the better the color saturation and color effect of the print, which also directly determines the color type of the printing machine. 2. Selection of printing ink type. Printing ink generally includes active ink, acid ink, dispersed ink, coating ink, etc. The ink type is generally selected according to the material of the fabric, and ink with good fabric coloring and good color performance is selected. 3. Selection of ink brand and model. Generally speaking, ink is developed for the brand and model of the nozzle. When choosing ink, you should pay attention to whether it is suitable for the nozzle model of the printer. In addition, the fluidity, brightness, color fixation, environmental protection, etc. of the ink are all aspects to be considered in ink selection. 4. Fluidity of ink. Ink with good fluency will not clog the printer nozzle.
4. Nozzle selection is the core: As the most important component and main consumable of digital printing machine, the nozzle plays a decisive role in the selection of digital printing machine. The type of nozzle determines the printing accuracy, the amount of ink jet, the printing speed, the production cost, etc. The selection of nozzles should comprehensively consider factors such as the type of printing material, the cost estimate, the requirements of production efficiency, etc. The nozzle, as the main consumable, should also comprehensively consider the cost and durability of replacement.
On the other hand, the quality of the equipment can be intuitively seen from the printing effect. The higher the printing accuracy, the better the coordination between the various components of the equipment, the better the coordination, and the better the precision. The quality of printing is not simply determined by a certain accessory. Even if the same model of nozzle is used, if the precision of the equipment is not achieved and the coordination between each component is not good, good printing results will not be achieved.
5. Selection of manufacturer strength: Without considering other factors, it is the first choice to choose a large-scale manufacturer. Large-scale manufacturers are relatively complete in R&D technology and after-sales technology. The manufacturer's R&D strength determines whether the products produced by its equipment are competitive in the market. Powerful after-sales support can solve your worries.
6. Choice of domestic and imported: my country's scientific and technological manufacturing level is becoming more and more mature, and the gap with imported machines has become smaller and smaller. Whether enterprises choose imported digital printing machines or domestic digital printing machines, the following factors can be considered: First, cost factors. Imported machines have higher costs in terms of freight and taxes. When choosing digital printing machines, imported machines are often more expensive than domestic machines. Second, key technology. The most important core technology of digital printing machines is the nozzle. Domestic digital printing machines also use imported nozzles. Most of the accessories used by some manufacturers are imported from abroad. In terms of equipment technology, domestic and imported are almost the same. Third, after-sales service. Good after-sales service support is one of the keys. Good after-sales service means that if there is a problem, the customer can come to the customer's home to solve the problem in time and solve the problem effectively.
7. Other factors: Site selection: equipment floor space and required environmental conditions. Environmental conditions are mainly reflected in: temperature and humidity. Printing costs: factory rent, labor costs, water and electricity costs, equipment purchase costs, ink consumption, and nozzle loss. Equipment operation conditions: understand the specific requirements of the equipment such as power, air pressure, and voltage. There is no best machine, only the best machine for yourself, and the one that suits you is the most important. When choosing a digital printing machine, you should choose it based on your actual situation and needs. Don't choose the expensive one, just choose the right one.
