I just got the first copy of "Valencia Intrigue" back from the printer today and noticed pronounced pixelation on some but not all of the curved portions of the image. Some of the fractal types had nice smooth curves and others had the jaggedlies! I put this down to KPT Fraxplorer probably getting into resolution problems with different formulas. Reducing the image size from 16 X 20 @72ppi to 8 X 10 @144ppi and applying blur helped considerably but I did want to print at the larger 16 X 20 size. The printer is a design jet 6 color and I am using Arches cold press 90# paper. Anyone have any suggestions? Thanks Mivan

print at 200DPI and make the images larger at first... i render fractals to 5200x5200@72DPI ... thats large, i know, but i get the best quality print results ... the output to the printer is 13 x 13 inches at 300 dpi ... and you wont see any pixel :D goodday Harmen

It depends on what your computer can handle. I do my print renders at 5000x3333 at 2000 dpi so that I never have to worry about issues like that. My advice is push the limits.

After doing a lot of high-end Iris prints, I've learned the magic specs. They are simple to remember, and I'm happy to pass them on to you. For best results: Render your images 300dpi at half the size of the final print The largest print an Iris printer can create is 48 inches X 48 inches, so rendering you pics to be 24 inches X 24 inches @ 300dpi will always yield fantastic results. If the image isn't square just make sure the widest side is 24 inches and render at 300dpi. Any larger than this is a waste of disk space. I got these specs from one of the premier print shops in the world. They do a lot of museum quality archive work. If you can't render this big, render as large as possible and use a product like Genuine Fractals to bump up the resolution: http://genuinefractals.com/ This is a truly amazing product and has a free trial download that is unrestricted. There is just a limited number of times you can use it before you have to pay. Even if you do not intend to print that big, rendering your images at that size and archiving them to CD will ensure that you will be able to print or reproduce your images at any size in the future. You can always print them smaller. Cheers Bruce

Oops! I just learned that Iris prints can now get as large as 60 x 90 inches. The math would be the same. 30 X 90 inches @ 300 dpi.
