Smoothen out text/notation?

[Olenr1]

Hi all you gurus!
I am pretty new with Photoshop
Is there any (easy) way to make text, or in my example notation/chords from a scanner more smooth and readable?
This is scanned in 600 ppi, i have tried 1200 ppi but it only looks different kind of bad. I would like to remove the "Castle-bumps"

what's your source for the scans, sheet music?

Don't know if you'll ever get it perfectly sharp without resetting it - but I took a try at it using blur and curves. Had to upscale it first and then reduce to post here - don't know what your eventual use is or how man of these images you have to edit.

HI @Olenr1
Post processing an image is best when staring with the best possible scan.
If possible, please scan in 8 bit per channel RGB color and save to PNG format. (JPEG has compression which may make it harder). That might give more options than scanning in B&W
Just a suggestion

as above - best possible quality to start off. not sure what scanner you're using, but if it doesn't have png, it might well have tiff.

then post a sample here again, at full quality, or link to...
