Rasterbator Tutorial

Rasterbator

When we are planning to enlarge our photos into posters, we can use a free online program named Rasterbator.  I know, everyone pause; it is a funny name.  Once you get past the name, you will find it to be an excellent program.  Below are the steps needed in order to successfully enlarge your image into a poster.  1

Select Image and Upload

Most students will upload their image from their desktop.  However, I have found that when trying to upload large files, (>20 Mb) the program hangs.  I have been successful with larger images when I uploaded them to my website and then inserted the URL of the image.  2

Print Size

If printing in grey scale, you will use the pod printers.  They print 8.5″x 11″ so select “US Letter”
When printing in color and using the district printing, we will print to 11″ x 17″  There isn’t an option for 11×17, but under “Paper Size, Custom” enter the dimensions: 279mm x432mm.  It is recommended that you do not exceed 4 sheets wide.   Add margin of 10 mm will make putting the poster together easier.  3

Effects

After selecting paper size, hit continue.  Here you will have an option for effects.  We are just enlarging, so choose “No Effects”  You can see the final output size for your poster under the preview image.  The program defaults to portrait format, but you may want to check and see if fewer sheets of paper are used in landscape mode.  Click continue. 4 No changes on this page. 5

Print to PDF

Select crop marks.  Click, “Rasterbate”  and the program will create a PDF of your poster.  Save the PDF to your Data drive and that will eventually be submitted to the district for printing.
