How to print a clear photo file?

If you directly print the paper document taken by the mobile phone, the paper has a dark white background and needs simple processing (making the white background whiter and the black words darker, that is, adjusting the color scale), and the printed document can be very clear. Let me take a transfer bill as an example to introduce how to deal with it. I use online PS link here.

Final processed image:

The steps are simple:

Step 1: Remove the border and transform freely.

Step 2, open the color scale to adjust.

Adjust the sliders on both sides to the middle. Look at the picture. Just make the background white.

I recommend your whole desktop scanner (hundreds or so).

Or practice mobile phone photography, which is very dark and paste, and most of them are not the pot of the printer. Highlight the exposure of the mobile phone, and then don't shake your hands when shooting.

Try to make the shooting background free of black things (just use white paper as the bottom)

If you only need words, you need OCR software for your mobile phone. If the screen looks good and the print is dark and fuzzy, change the printer to print.
