What is the reason for color deviation in universal printer printing?

　　Usually, customers are accustomed to using a universal printer to randomly print ink as a marker to determine the performance of the ink. In fact, each brand of ink has its own unique characteristics. Taking the current three most popular inkjet printers as an example, although they all use the three primary colors of C (cyan), M (magenta), Y (yellow), their printing functions are different. For example, one brand's M (magenta) is slightly purplish red, while another brand's M (magenta) has a hint of rose red. Even for printers of the same brand, the printing function may vary depending on the type of machine or the batch of ink used. If you find that the printed colors are not ideal or have severe color deviation, there may be the following reasons:

　　1. Printing settings: This is closely related to the saturation percentage selected by the operator when assigning colors, and the selection of other DPIs and printing speeds can also affect the printing effect. Secondly, it is closely related to the printing software used, such as when using Photoshop 3.05 and CORELDRAM6.0 to print a picture, the effects are vastly different and each has its own characteristics.

　　2. Using regular printing paper, the background color of the paper is darker; The paper is too poor, and ink enters the fibers of the paper or dissolves, changing the depth of the color in the picture. We suggest using inkjet paper, which is coated with titanium dioxide as the base material, to make the ink spread more evenly.

　　3. Print head condition: If the correct printing settings are used, the same paper will print the same image on different colors, which is caused by the unstable inkjet volume of the print head. Due to repeated cleaning of the print head, damage may occur.

　　4. The problem with ink cartridges: If the ink chamber of a colorful ink cartridge is discolored, or if a certain ink area presents air, it will cause the ink to not print out, and the picture will lean towards a certain color.

　　Printing colors is actually a reflection of the wavelength reflected by an object in our eyes. When the wavelength is between 600-570nm (nanometers), we consider it yellow, 760-630nm is red, and 450-430nm is blue. The difference in fineness between them depends on the saturation of the three primary colors proposed by each manufacturer, as well as the perception of cells by the human eye.
