In fact, this question is also very simple to say! It was completely unexpected at first. . .
Reason one: When you change the ink cartridge, you only change the black ink cartridge. This problem is probably encountered by people who use Epson printers together. Geige ink cartridges or other compatible ink cartridges, if only one color ink cartridge is changed, the original ink cartridges of other colors will still be used, and most of them will have problems. I don't know the specific reason, because its ink is dye ink?
Reason 2: The ink used in the grid is far from the original one, so the graininess will be obvious when printed, and the white stripes you said will be more obvious.
After that, did you see the solution?
In fact, it is enough to replace all four color ink cartridges with one grid. After the replacement, do you feel that the original skewed font has become correct?
If after this, you feel that the printed effect is still not as delicate as before, then improve the printing quality you are using now by one level! After all, compatible ink cartridges are so much cheaper, so don't save ink.
