How to distinguish the accuracy of a universal printer

　　Print accuracy dpl (Dot Per Inch): Refers to the number of dots that a printer can print per inch, which is an important standard for measuring printing quality and the most basic judgment

　　The indicator of printer resolution. But the resolution of a universal printer cannot be seen, how to distinguish the accuracy of a universal printer? We can use the following three methods.

　　1、 The machine itself

　　1. Repeated printing (without displacement, high accuracy)

　　Making a "cross" and repeating the heavy printing process 3-10 times can completely overlap, indicating that this universal printer is not misplaced, has high accuracy, and the machine is OK. Conversely, it is PASS.

　　2. Small font printing (discrimination accuracy)

　　The third font set in Photoshop, CORELDRAW, or AI should be printed out on a universal printer and checked for ghosting using a magnifying glass. No ghosting indicates no ghosting

　　The accuracy of this universal printer is high, and the machine is OK. Conversely, if the accuracy of this device is questionable, it can be directly passed.

　　2、 Software

　　It is necessary to provide ICC and ICM curve software for color adjustment, as well as RIP software for printing white ink.

　　3、 Ink

　　Firstly, the ink used in tablet printers is different from that used in regular household or office use. Secondly, the ink for tablet printers mainly needs to consider the following factors:

　　1. The smoothness of ink

　　Ink with good fluidity will not clog the printer nozzle. After being left for half a month, the nozzle still flows. Ink with poor fluidity will clog on the same day it is used, and

　　Some of them are completely clogged, and you can't even clean them if you want, which means that the nozzle has already been "reimbursed".

　　2. The reducibility of ink color

　　You can compare the printed image effect with the image on the monitor, and the closer it is, the better the ink's reproducibility and brightness. Why do we say the closer we get,

　　Instead of being completely consistent? Most customers use either LCD monitors or regular CRTs.
