I have used the splattered pieces of card and re-printed the logo onto them. I have then used the crop marks to cut them to size. I am thinking I may duplex them with the same florescent colour on the reverse or triplex them with the florescent colour in the middle. Ideally, I would like to triplex them like Generation Press do. I would be able to mock this up, but not produce this on a large scale.
This is an example of a florescent colour edged business card that I got from Generation Press when I visited.
This would work particularly well with the colour scheme I am working with. Definitely going to mock this up.
