That does look better. Not sure what’s up with the logo on this one, I’m pretty sure it should look darker and more consistent in colour, like the ‘s’ at the bottom. Do you think maybe this was taken with a flash? A couple of the other examples would probably benefit from correction more than this one, but I thought the strip may make it fairly straightforward.
That Image has many Problems… I played with it my self, and the CMYK Marks are helping, but they are faded and not consistent (look at the Magenta ones at the Bottom they are much brighter than on the top) to make things worse there are a lot of JPG Artefacts in that Images…
so depending on the mark you choose to calibrate your image you will get an different result…
also there is an reflection of some sort in the lower right… thats also responsible for the color change in the Logo it self…
