Tiling And Preparing Your Mural For Printing Using Corel Draw Version 8, 9 or 10
Written by: Ernie Ziegler, Memories On Tile , January 2003
For purposes of this tutorial lets assume:
1. Mural size is 12 x 18 inches.
2. Image size is 12.5 x 18.5 inches
3. Your pre-prepared Tiling Grid is 12 x 18 inches.
4. Mural is in Landscape position 18 inch dimension is horizontal.
5. A total of six (6) 6 x 6 inch tiles are required.
NOTE: I usually size my image 1/2 inch larger all around than what my finished mural will be. This allows some wiggle room for positioning your tiling grid.
Tiling Your Image
Open Corel Draw and start a new drawing.
On the "Property Bar" set a page size length to 22 inches and the height to 16 inches.
Import your image into Corel. On the menu bar click "File", and on the File Selection dialog box click "Import"
On the "Menu Bar" click on "Arrange", and on the "Drop Down Menu" chose "Align and Distribute". In the Align and Distribute Dialogue Box select "Center on Page". Click "OK".
Import your "Tiling Grid" into Corel. Using the "Pick Tool" position the grid over your image.
Using the "Pick Tool" click on the image.
On the "Menu Bar" click "Effects". Then on the drop down menu click "Power Clip" and "Place In Container" the "Pick Tool" will now become a large black arrow.
NOTE: The image is now your "Contents" and the "Tiling Grid" is the container.
Use the large black arrow to point at the "Tiling Grid". Click the left mouse button.
NOTES: Your Image should now be contained within the "Tiling Grid" and all extraneous portions of the Image should have disappeared.
At this point I identify by Alpha-numeric code just outside the gridded image all the individual tiles within the "Tiling Grid".
I do this by assigning an Alpha designation (A, B, C etc.) to each column starting at the upper left of the grid and moving horizontally to the right. In this instance you will use the Alpha codes A thru c.
Then I assign a numeric designation (1, 2, 3 etc.) to each row starting at the upper left of the grid and moving vertically down. In this instance you will use the numeric codes 1 thru 2.
This now is what I call my "Master Image Grid" for a 12 X 18 inch image and I save the image to a folder I create for it. This folder is where I also "save to" all the individual tile images (see Step 9) after they are resized for printing.
This "Master Image Grid" now serves as an aid for printing, as a guide for assembly or as an identifier in the event any individual tile may need replacing in the future.
Using the "Pick Tool" click on the "Master Image Grid" and move the entire grid off to one side of the screen.
On the "Property Bar" click on "Arrange" and on the "Drop Down Menu" click on "Break Apart".
NOTE: Your mural (though it still appears as one whole entity) is now in individual tiles.
This step is where you will provide for overlap and full bleed.
On the "Property Bar" set the paper size to the size paper you will be using in your printer. .For this tutorial we'll use 8.5 x 11.
With the "Pick Tool" click on tile "A-!" and position it on the printer page.
This resized image is now ready for printing of the transfer.
On the Menu Bar click "Bitmaps" and on the Drop Down Menu click "Resample". A list box will appear. Chose a width and height that is 1/10 (.1) larger than your tile size. In this case 6.1 inches.
STEP 7 Continued
NOTES; This resized image should now be saved to the previously created folder. This is also the point in time that I prefer to do a little tidying up before saving the resized Image. To do this I click on all the Tile/Images located off to the side of the Print Page and "Delete" them.
Next I save the Resized image on the Print Page to the previously created folder.
Doing the foregoing does add a little work to the process, but provides an end result that simplifies any future remake of the mural.
The image on the Print Page is now ready for printing the transfer.
NOTES; Before wrapping the transfer around the tile and pressing I use a permanent marker to mark the "Alpha-numeric" code number on the back of the tile. This is a great help when assembling the mural.
I give no times, temperatures or pressures for pressing as there are too many variables. I leave that to you to work out for your particular set up.
Import your Master Image Grid.
Repeat Steps 7 and 8 for each of the tiles left in the mural.
NOTE: You should now have six (6) tiles with Alpha-numeric codes on the backs of them that when assembled look like the following.
