After typing in PS, the black words printed are not pure black and a little red. This may be because the font you used does not support pure black colors. If you want to print pure black text, try using black font or adjust the print settings to make the paper black. You can also adjust the color value in PS to make the text pure black. In addition, during printing, due to the quality of the printer and paper, it would also affect the printing effect, so there may be some errors. If you want to get the best printing results, it is recommended that you test it on different printer and paper to determine the best results.
