If I print a low res image file at a small size image at high res…..then scanning said print – will it be higher res than original?

Here is the crux of it….
A while back I produced some stunning art visualisation – abstract paintings – this was like at school!!
The originals were lost in a fire – go figure – and I was left with only the original scans….
However, during 8 years and many new laptop an hard drives, sadly I cannot find those original 8 scans anywhere!!!
All I have is what I believe to be screenshots of the original scans! Therefore, we are talking 800kb per image to 1.5mb. Update 2: I am furious to say the least, but alas, what can I do.
Anyway, I had a bit of a brain wave – or brain fart – and thought If I were to print out these files at say 6×4 at the highest res, then scan those prints….Would I get a better quality (resolution) image than the original screenshots?
What I would try is this:
Print the screen shot at the largest size that it can printed while maintaining photo quality. To calculate what that size is, divide the resolution of the file by 300. Use 300 because when you print the file, you want to be at 300dpi to maintain photo quality.
Then scan it using a good flatbed scanner or take a photo of it using a good camera (i.e. not a phone). Print the resulting file at the a size no larger than the resolution of file divided by 300.
Your idea has merit. In the days of film when someone want to make a very large print of a small 35mm negative, they would make a copy negative using a 4×5 camera. They would take the 4" x 5" copy neg and print that instead of the original 35mm negative. This was done to reduce the magnification required to make the desired size of print. Therefore, it makes logical sense that you could get better image quality from scanning a small printed image and using that "copy scan" to print a larger file to avoid the image from becoming pixelated.
I would scan the image using the highest optical resolution and with the highest color bit depth, and then save it as a TIFF. Color bit depth refers to the number of shades or tones from pure black to pure white. The bit depth increases exponentially and not in a linear fashion. So an 8-bit JPEG file has 256 shades (2^8). Adding one bit will double this amount. So a 16-bit file has 2^16 or more than 65,000 shades. This will prevent banding and will result in a better-looking image, but a much larger file too.
When printing the screen shot, be certain to use a good quality glossy photo paper. Glossy paper will show more detail than semi-gloss and much more than a satin or matte.
I've never tried this, and I'm not certain that it will work. However, it could especially when you take into account the expected viewing distance of the final image. If it's going to be put on a wall and viewed 6-10' away, it will look much better than if you were to view it 18". This is how you can make a billboard from an 8MP file. It's printed 10dpi which would look horrible at 1-2', but at 50' your eye can't see the individual dots, so it looks just fine.
The resolution of a print is the resolution of a print – nothing can change that. So if you scan a low-res print at high-res you will get a good reproduction of a low-res image – at that self-same low-res.
Sadly you have learned two things
* Always copy your original artwork using the highest resolution camera you have.
* Always backup those images to one or more of the following locations. CD/DVD/BD disc, external hard drive or cloud backup service like BackBlaze
As mentioned, there is no way to add resolution to an image. There just is not enough data to do that
No, sorry, we can't print that, the resolution's way too low. It's only 72 ppi and we print at 100% dpi. And if we try to bring the resolution up, your picture will be way too small.
