Hi @JoeGuy.
I finally got my custom bind back from Spink and Thackray. Unfortunately it was damanged in transit so they have offered to replace it. Luckily, it does mean I can try and fix an issue with the colour matching. The colours looked a little washed out and the red spine marvel logo in particular looked really off. Almost like a pink tinted red. I know you previously gave me your GIMP files to take a look at, but how did you provide them with the final output?
I was advised by a friend who works in print to convert it to CMYK which looked fine before I sent it.
A reply back from their support was that RGB was the prefered method over CMYK.
How well did your marvel logos line up to the official ones? I really want them to match on the shelf.
Here's how the initial cover looked anyway.
