Extract Handwriting and Print from Background

Hi! I'm not the smartest person when it comes to image processing. I have a quite simple problem I need some help with. I have images with a red frame as background:

The goal is to remove the red background and keep only the information in front, handwriting and printed information. I did come close by only using the red channel of the image and apply a threshold, but it comes with some noise and thin characters. So I need a smarter algorithm which gives me nice, strong characters for OCR without noise.

Best regards, Billie
