You need a screen size of at least 1024 by 768 pixels.
Tip: If you are struggling for space in this window, press f11 to give you as much space as possible.
Badges are in random order.
Tip: To shuffle them into a different order, press f5.
Tip: To adjust a badge's position click it and move it. Click again to let go.
Badges are grouped in sets of 30. Scroll so a set is in the middle of the window.
Press Alt+PrintScrn (top right of keyboard) to copy the window to your clipboard.
Open your graphics program/photo editing software and paste from the clipboard to a new picture.
Crop the picture to just contain one badge set and save the file.
Repeat the process of scrolling down and copying the window until you have files with all of your badge sets.
Tip: Click the space between badges for the page to scroll down exactly one set.
Badges that are too large to be arranged within the sets are shown below the sets. Copy that screen and add those badges to your T-shirt individually.
Instructions continue at the bottom.
Right click the picture on the right and "Save picture as" test.gif to where your badge set files are saved. (The saved picture is bigger than shown here)
Open the test picture (above) in your graphics/photo editing program and see if you have a print preview option. You need to set up to scale to fit A4 landscape paper. If the percentage size is shown (it should be about 84%) make a note of what it is. Now set your printer to print to iron-on transfers. Keep plain paper in the printer at the moment and print a test page. It should be reversed and without losing any of the border lines. If it was not reversed automatially or you don't have an 'iron-on transfer' setting you will need to mirror the images, either in the printer settings, or reverse the images using your graphics/photo editing software.
Put your iron-on transfer paper into the printer and print your badge picture files to the same percentage size as noted. Use the best quality setting.
Follow the instructions that came with your iron-on transfer paper to put the images on your T-shirt.
As a general guide the front and back of a medium T-shirt will take nine A4 pages of 30 badges each, some sheets cut in half to fit on. I know rallyist who will be on their fourth T-shirt or maybe ironing them onto their tent flysheet!
