When buying a UV printer, in addition to speed, the accuracy of printing is also very important. This is often ignored by customers. This accuracy is really important, and it is related to future use and proofing of the finished product.
It is very important to understand the printing accuracy. To understand the accuracy, you first need to know DPI (dots per inch). What is DPI? Simply put, multiply horizontal dots by vertical dots. For example, for example: 360x720, what is its DPI? The answer is 259,200 points. The printing accuracy previously asked by customers is actually like the screen resolution of the mobile phones and computers that people use today. When opening Tencent Video on the phone, we will adjust the image quality to 1920x1080. Why? Because of this picture quality and resolution, it makes people feel comfortable watching the video. On the contrary, if you watch Tencent video with 720x600 picture quality, then the editor will not exaggerately say that I don’t want to watch it, directly Turn it off! The same is true for computer screens. In the past, when the computer screen was low, everyone would make do with it, but with a resolution of 1920X1080, anyone who doesn’t want to turn on the worn-out computer anymore will let you put it on the screen for 5 minutes. I feel uncomfortable.
In summary: DPI is like the resolution of a mobile phone or a computer for UV flatbed printers, the higher the better.
