Make Wall Sized Posters With Your Printer

I’ve got a number of fellow artists and friends who I can see using this free software to create something really fantastic!

The Rasterbator is a free download, or alternatively Web based service, that allows you to blow up any photo to almost any size.

Aibek at MakeUseOf.com provided the following usage instructions:

Steps:
1. Get Rasterbator: You can either download it from here or use its web version. Although, keep in mind that online version puts some restrictions on output size and resolution
2. Run rasterbator and select source image
3. Select paper size and alignment: The rasterbated image will be automatically split onto several pages, so you need specify the format of each unit paper(A4, A3 etc) and its alignment(horizontal or vertical). If you plan to print poster yourself then make sure to select paper format supported by your printer(ex; A4)
4. Define output size: Output size is defined by the amount of papers to be used for image width or height. For instance, you can tell rasterbator to produce a poster with a width equivalent to 12 horizontally-aligned A4 papers(see poster below).
5. Set rasterbation options: Specify color and resolution settings
6. Select output directory and press Press ‘Rasterbate!’
7. Done: Print it and put it on your wall
