This is a relatively new process to our shores. And unlike edge painting and gilding, it is automated, making it suitable for industrial print runs: from 500 to tens of thousands.
The process uses inkjet to print CMYK to all 4 sides of your books or invitations.
While this process will work fine for solid colored edges, it truly shines when you want to add vibrant colorful images to a book block. The more intricate the image, the better!
