Five-layer printing (CWBWC) is the technique of choice for producing double-sided blockout graphics on clear media on one side of the media, such as window graphics, all in a single run. The black, blockout layer in the middle allows you to print two different breath-taking, right-reading images that can be viewed from either side. Previously, this application could only be accomplished with specialized media or laminating two separate prints together. Now, it can all be set up in the printer software on the EFI™ VUTEk® 3r+ and 5r+ and the EFI Pro 32r+ roll-to-roll printers, and printed in a single pass.
Images can be the same OR different!
When creating a five-layer blockout graphic, you can use the same image or two different images as long as they’re the same dimensions. Here’s how to set up the image in the printer software:
- Image 1 > white ink > black blockout layer > white ink > Image 1
- Image 1 > white ink > black blockout layer > white ink > Image 2
Five-layer blockout images can print as a shape!
Five-layer blockout printing isn’t just for square-up images. You can use two different images that print as a shape. Think circle, bottle or any shape that is symmetrical when mirrored in the RIP. The white ink and black blockout layers will automatically conform to the shape of the image. Setting up the file in the printer software is easy:
- Image 1 shape > white ink > black blockout layer > white ink > Image 1 shape
- Image 1 shape > white ink > black blockout layer > white ink > Image 2 shape
