Beginning note: This process is requires more steps than printing cards with borders. You will run the paper through your printer twice for the outside of the card. It requires a 13" wide inkjet printer.
Compatibility - This process will not work with newer Canon printers like the PRO-1000, PRO-100, PRO-10, and PRO-1. This is because they feed paper from the center of the paper tray.
This tutorial covers printing the outside frontof a 7" x 10" sheet so that the front is borderless. You should Review Our Other Tutorials for how to setup the back and inside for printing.
In Photoshop or other software, open your photo for the outside front of your card. It will need to be 5" x 7" exactly.
The image above represents a 5" wide x 7" high photo that will go on a horizontal open card - one that opens like a book.
Note: To create a card that opens vertically, you will need a photo that is 5" high x 7" wide.
In the printer properties, set your paper size to 5x7.
Choose the borderless printing option.
Landscape for a card that opens from bottom to top.
Portrait for a card that opens like a book.
Set the borderless expansion to its minimal setting
This minimizes the chance ink will print over the fold line. Here are Epson and Canon screengrabs to help you find that setting.
Loading your paper
Put the paper in the printer long end down (opposite from how you would normally put paper in the feed tray).
When you print, the printer should bleed ink off the three exposed edges (top, right, and bottom) of the right hand side of the paper on the right hand side of the score.
Finished outside front of your card is now complete.
Troubleshooting - If your image comes out so it is upside down when the card is folded, you will need to rotate the image 180 degrees. Consult your photo software for help with that process.
