How to better distinguish the difference between eco solvent printers 1.8m and UV flatbed printers
How can we better distinguish the difference between eco solvent printers 1.8m and UV flatbed printers?
This is a headache for people who are new to eco-solvent printers and UV flatbed printers. The following are some differences between the characteristics of eco solvent printers 1.8m and UV flatbed printers:
Comparison of the characteristics of UV printers and eco-solvent printers
Eco-solvent printers have long been known to many people because of their appearance. In recent years, the appearance of new UV flatbed printers is similar to that of eco-solvent printers, causing many people to confuse these two products. The machine has a clear understanding. Here I will describe the difference between these two types in detail, hoping to help you choose a machine. It can be roughly divided into the following points:
1. ink
As the name implies, the ink needed for eco-solvent printers is eco-solvent ink, and UV printers are UV inks. Because UV ink is characterized by the solidification of the solvent when exposed to light, the ink cartridges containing UV ink are all black, while eco-solvent ink cartridges are transparent. One point is very intuitive and can be distinguished at a glance. In addition, UV inks are generally imported inks, and the price is relatively higher than that of weak solvent inks.
2 .ink path system
Due to the characteristics of UV ink that is easy to solidify when exposed to light, the matching ink cartridges and ink tubes related to ink are required. The ink system such as the ink sac should be designed to be black, so as to ensure the smoothness of the ink, so as not to block the nozzle after solidification. Of course, there is a problem here, that is, the ink cartridge is designed to be black, and it is inconvenient to control the remaining amount of ink, which may lead to the lack of ink and lead to wire drawing, ink breakage, etc. In order to solve this problem, we installed an alarm on the ink cartridge. system, when the ink volume is less than a certain value, it will alarm, which is also an advantage specially developed by our company.
3 .curing methods
In the printing process of the UV printer, the UV lamp LED cold light source is used to irradiate it, which realizes the effect of instant drying. Eco-solvent printers use a heater drying method. After printing, they need to be placed for 1-2 minutes. Some require special materials (different materials such as glass acrylic plates) to be placed for 3-4 hours. Some special materials even need to be placed for 3-4 hours. Bake it in the oven to enhance its effect and adhesion.
4 .print effects
Because the UV printer has the characteristics of instant drying, it prints all ink dots, and the whole picture is composed of dots. At the same time, the UV printer can print white ink and varnish, so the UV printer can print the effect of embossing, weak solvent The pictures printed by the printer are relatively smooth and supple, which is why many customers will ask why the eco-solvent printer has higher printing accuracy than the UV printer. Here we need to be clear that the printing accuracy is only related to the print head and printing software. It has nothing to do with the ink. The reason for the different effects is that when drying, because the UV machine dries immediately, the dot-shaped ink droplets ejected from the nozzle are directly solidified, while the weak solvent printer is in the heating process, the ink droplets will be It spreads to the periphery, so it looks very smooth and delicate after drying. In addition, the weak solvent cannot print white ink, so it cannot print the relief effect.
5. coats
Eco-solvent printers generally need to do pre-press treatment before printing materials, including jetting, baking takes about 20-60 minutes, and post-press processing also takes so long, and the efficiency is very low in comprehensive comparison. Time is wasted on processing, and the time actually spent on printing is shared. In addition, it is necessary to invest more in corresponding equipment (printing and baking equipment). The smell of spraying equipment is relatively large and harmful to human body. The UV machine is more environmentally friendly and can realize office-like operations. Even the coating layer is very simple. It can be wiped on the surface of the material manually. Simple operation is also a main feature of UV printers.
The above points are just a simple comparison of the differences and characteristics of eco-solvent printers and UV flatbed printers. I hope that you can have a full understanding of the required machine when you buy the machine, so that you can better determine which machine is suitable for use. It's the machine you want.
