Noise near font after adding text via ImageMagick

Question

I put text on image and have some noise. How I can fix it? Image magick options:

[
                currentImage,
                "-font", "Micra-Bold",
                "-pointsize", "40",
                "-strokewidth", "1",
                "-stroke", "black",
                "-fill", "white",
                "-gravity", "North",
                "-annotate", "+0+10", req.body.memData.actNumber,
                "-gravity", "South",
                "-pointsize", "26",
                "-annotate", "+0+10", req.body.memData.actText,
                ""+memsPath+tempName+".jpg"
            ];

and my image

Answer 1

The noise may be JPEG artifacts. Try using a higher quality (your image has quality 70 according to "identify -verbose"). So, try

"-quality", "92",

for example.
