I tried a program like that. I don't know if it was THAT program or one like it, but I found that home printers are not accurate enough to make tiled images, without changes in ink density and other issues that make them LOOK like they were pasted together out of 8.5x11" paper.
If you are just going to enlarge a drawing to make a pattern then this should work fine.
Right now I've got the pattern glued down to 1/2" plywwood, 48" tall, this is the beginning step in making a master. The pattern was copied, piece by piece and glued down, closely enough you can hardly see the joints, unless you look close. Well, that printer went south, and the computer the original was on joined the printer. If I could take a picture of it, then color the picture, that would help, but not doing well on coloring images. Also, would need to print each part on 8.5X10" paper - and my printer/computer refuse to let me enlarge. The first one I did, but 2' instead of 4' was hand painted - which is a bit of a PITA, but at least I know it will come out right.
So, if I can enlarge the picture of the drawing, that would be acceptable, can paint it at least. But would I be able to print individual parts, then glue them together, or would the whole thing need to be printed on a single piece of paper?
If nothing else, I can always trace the pattern, glue the tracing down, and paint. Which would mean I would have to trace every single one. And it is a bit complex. Aaargh.
Ah, just struck me. I can get a huge rubber stamp made, and simply stamp the design, then just need to paint.
