Here's an image I made of black letters in a red field (RGB values: 237, 28, 36)... On the left I saved it as a .png file, then expanded the image, closed and reopened the file, then copied the results below it, and tried to change the red to black. On the right, I did the same thing as a .jpg file, then I combined the results into one .png file. Hmm, I wonder which red is more faithful to the original image? The .png or the .jpg?
Then there's mostly text on a white background... upper text is .png, lower is .jpg. When I clicked to change the background of the .jpg's white to red, the spot indicated by the black arrow was the only thing that changed. The black outlined white arrow is the approximate location of my second attempt to flood fill the .jpg with red (as you can see it spilled over into the first part of the .jpg text area.
Don't get me wrong. JPG files are fine for photographs of things that are not a single color (the sky, birds, a family photo), but when it comes to things that have a single color (such as a band of color that goes around a model rocket, applied as a decal, it's not good, and if any upscaling is involved, it gets significantly worse. Ideally when it comes to text, vectored graphics would be the best, but IMHO .PNG files are adequate.
