Sending an image to a commercial printer is both expensive and time consuming. You have to save the image to a compact disc and deliver it to the printer or spend time uploading the image to the printer's Web server then pay to have the image printed. You don't have to use a commercial printer--you can enlarge and print an image on multiple sheets of paper using your home or business printer. After the printing process is complete, assemble the multiple sheets of paper to form the enlarged image.
Open your computer's graphic manipulation program by clicking on the program's icon on your computer's desktop or by clicking "Start" then "All Programs." If using a Mac, click on the "Hard Drive" icon. Click on the "Applications" folder then the graphic manipulation program's name.
Click on "File" then "Open." Navigate to the directory containing the image file you want to print using multiple sheets of paper.
Select "File" then "Print." Click on the "Properties" button.
Click on the check box next to "Tile," "Multi-Page," "Tile Large Pages" or similar wording. Note that the "Tile" option may be on the "Page Layout" or "Advanced" tab.
Select the amount of enlargement you want under the heading "Tile Scale" or similar wording.
Choose the amount of "Overlap" (an extra portion of the image) you want printed on each sheet of paper--this lets you match up the multiple sheets easily. Note that not all graphic manipulation programs offer the ability to specify overlap, and the option may be labelled "Borders" or "Poster Printing." If one of these options is available, select it then specify the amount of border you want printed on each sheet of paper or what size of poster you want to print.
Click on "OK." Click on "Print" or "OK" to print your image using multiple sheets of paper.
Wait for the printed pages to dry for three minutes, if using an Inkjet printer, to keep the ink from smearing.
Assemble the image on a clean, flat surface.
Use a paper cutter to trim off excess borders/overlap that interfere with the assembly of the image.
Lift one sheet of the multiple-page image. Place a piece of transparent tape, sticky side up, on the edge of the paper on the back.
Place the sheet of paper that matches that portion of the image onto the piece of paper with the tape.
Repeat Steps 4 and 5 for the next portions of the image until it is fully assembled.
Do not use scissors to cut the multiple sheets of your image--your borders/overlap will not line up correctly.
