How can I create huge billboard sized files in super high dpi?

Hi guys,

I am printing super high res images onto fabric. My print guy has instructed me to create my images in 1440 dpi and my fabric is 58 inches wide and about 80 yards long. I need to create ONE image so they can just print it continuously along the whoe piece of fabric. So I need to create a REALLY BIG image. They have recommended Adobe Creative Suite, but of course I want to do it with GIMP.

Just today, I installed the latest GIMP, and it doesn't seem to be letting me create even a 58x72 inch image in 1440 dpi. Is there an add on or a way that I can create huge tiff files in GIMP?.....or do I have to shell out the cash and get Creative Suite?

Thanks!

Tara

58 x (88 x 3 x 12) = 183744 square inches, at 1440 dpi would mean something like 183000 * 1440 * 1440 * 3 = 1143034675200 bytes. That's 1143 GB - entirely unpractical. I don't think even super hi res for posters really means 1440 dpi (unless the image is scaled).

Anyway - I suspect you will want to look at vector images instead of bitmaps. (or panelling)

How can I create huge billboard sized files in super high dpi?

Well, I got it to work, at least theoretically. I think it's in the same way that you would create a large image in Photoshop, but to test it I opened an image that I already had that was 72 d[i and about 35 inches wide, an old pic of my cat.

With Image>Scale Image I bumped up the resolution, then with Image>Canvas Size I bumped up the size, in this case to 58X72 inches. The thing is to play with the "chain link" icons in these boxes, if you try to change the resolution then all it will do is inverse the size if you don't unlink them. (Of course, I'd like to hear from any of the experts on this list. I'm just a graphics hack.

By the way, have you ever made an image this large before? Even at 58X72 at 1400 dpi with color that's going to be a monstrous file. My machine went for minutes and hadn't finished resizing it so I exited. Of course on this Mac I only have
one gig of ram at present, but I don't know if any computer could handle an 80 yard
file, Photoshop or Gimp. You'd better have a lot of cpu, ram, and extra hd space,
swap file space.

Do you have any links or examples of fabric you've created? I've always been interested in that.

Waiting for real the advice... Dan

1440 dpi would mean you print many many lines of pixels on each single thread of the fabric. You misunderstood the printer. Ask again what resolution they can actually print, and use that.

There is not much sense in an image with these dimensions and this resolution. 1440 dpi would be even suitable for film negative (a 1 by 1 inch image to be scaled up for apreciation).

Since you managed to scale a image up to those dimensions in your system, and suppose you can save the image with those dimensions with the tiff plug-in, you can safelly create your artwork using 90dpi (or even less) . . when you are done,
flatten the image, scale it up to the desired resolution, as you said you managed to do, and export it to tiff.

At 90dpi you should be using 58 * 72 * (90 ** 2) * 4 /(1024 ** 2) = 129 MB per layer, which is feasible.

The thing is, in what format does the company ask for you to contribute your work in? I know Photoshop used to have the ability to export to vectors even a long time ago, and certainly Illustrator I am assuming is still a part of Adobe CS, but if you can use vectors you can start or work with a bitmap or photo etc, and edit in gimp, however you begin the images, then convert to vector.

I did a search for "Exporting from Gimp to vectors" and it came up with some pretty interesting stuff, especially the svg stuff.

Hi Tara,

This is a strange one.

1440 dpi is indeed high resolution - digital images for use in glossy magazine art, ads, etc. are usually specified as 600 dpi. Any resolution over 100 dpi or so is completely wasted when printing on cloth, no matter what the thread count. "High resolution on fabric" is a contradiction in terms.

A 58x72 inch image at 1440 dpi is not just big - it is big enough to be impossible to process on a desktop computer due to memory, bus speed and drive speed constraints. We're talking 8.66 x 10^9 a.k.a. 8.66 gigapixels. By contrast, a fairly decent digital SLR camera photo has 18 megapixels, about 1/400 the requirement your printer specified for a 58x72 image file.

It seems likely that what you want for a REALLY BIG image is a vector format like SVG. The "canonical" Free editor for that is Inkscape. Vector images can scale to any size from the head of a pin to the side of a large building, with no loss of resolution. Vector files do not store pixel values, they store mathematical descriptions of shapes, colors, and gradients that are "reconstructed" as images when viewed or printed.

You might want to double check with the printer about that specification - unless I am missing something really basic here, it has to be an error.

Inkscape has a tool for that - you import the bitmap image, tweak the various factors affecting precision, and after a suitable amount of grinding out comes the vector version.

I think he meant 144 dpi, which is a common resolution used for colour images in print.

If the thread count of the fabric is 200 or higher (e.g. a high-end sheet or a silk shirt) it'd plausibly take twice the thread count or more, but I'd say try a sample at 144dpi.

So, the 144 would be basically twice the web resolutio of 72 to make for better resampling on resize, or no relation? Dan

Well, if by Web you mean World Wide Web, no, no relation; there are 72 points to the inch in printing, and a lot of printing setups in practice are optimised to work best with multiples of 72dpi when making a half-tone screen for each colour - the ink is either on or not-on at each location ad the RIP in the printer (or a separate box in your case, probably) turns each pixel in the image into a rough circle of lots of device dots, fewer dots for less colour.

Slightly longer answer - The hardware device might be 1440 device dots per inch, but at 144dpi that gives a 10x10 square of little dots for each pixel, so only 100 colour levels are possible. That's likely to be enough for printing on fabric, though. At 72 or 75 lines per inch (ppi, or dpi from the image perspective) on a 1440dpi printer you get 19 or 20 dots on a side, so around 400 levels, and although that's more than 8-bit colour can represent, it gives the RIP more felxibility in the shape of the clumps of dots.

And if the final product is to be viewed at some great distance (eg, a billboard) then 144 DPI may be higher than required. We did a 30ft/9m long banner some time ago that worked out fine at 75 DPI - we could likely have gone lower, since it was so far off the ground.

But yeah - I doubt you could tell the difference between _any_ fabric printed at 200 DPI and anything higher, even up close.

I suspect the printer says 1440DPI because the spec sheet of his own printer says so. But on a printer the DPI is the size of the ink dots, and you need many inkdots per pixel.

Something which is 58 inches high is seen at such a distance than you won't see details below 0.03 inches (about 1/2000th of the height). At 60PPI the pixels will already be way too small to be visible.

When you select File -> New from the menus, expand (ie. click on) "Advanced Options". It will give you some additional controls where you can specify the image resolution in pixels/in. You can then enter the image width and height as 58 and 72 respectively and set the units to "inches".

For an image of the size you are talking about, a vector based image might be more appropriate but that is for you to decide based on the type of imagery you want. (ie. photos vs pen/ink illustrations).

Also, Tara if you Google: "printing dpi vs pixels" it comes up with some very good results having to do with what you're trying to accomplish, especially this one:
http://www.rideau-info.com/photos/mythdpi.html which specifically addresses at some point a 1400 dpi printer. And this one makes it "pretty" clear: http://www.pptxtreme.com/help/psdimport/ResolutionExplainedPixelsDPIInches.html I had read these so long ago I forgot, and I am going with "the printer is 1400 dpi, not your image file" theory. What I would do is set up a small test run of some sort with the printer, where you try one or a few of your best fabric pieces, with intricate color and design complexities, and see if there's any difference for each at say like 144, 200, 300 px/inch Then adjust to taste. You will probably want to be able to go as low as possible on px/inch if you do stay bitmap and you do need one continuous file, cause even then that's gonna be a giant. Unless you can go with vectors.Very interesting though. Dan

2.8 rc1 on XP

Has anyone gotten the windoze installer version of 2.8.0-rc1 to work properly? I've been running 2.7.5 for a while but when I tried installing the 2.8 rc1 I'm having problems. The gimp comes up ok, but when I attempt to load a .jpg file it hangs; as I recall it's spinning its wheels in ufraw-gimp.exe (I forgot to write down the exact name, but I think that's it).

ufraw-gimp.exe is a third-party plug-in to load RAW files. If it has registeres itself as a file loader for JPEG files (quite possible) and fails*, then this may cause the problem you've mentioned.

You should remove this plug-in from the plug-ins directory and try again.

*The fact the this plug-in ships with its own copy of bzip2.dll has cause problems in the past. Re-installing the current, but pretty old version of it may fix the problem - or cause additional problem in GIMP.

2.8 rc1 on XP

The problem appears to be unrelated to ufraw. I've removed all versions/relics of gimp and ufraw that I can find: uninstall, plus remove directories remove registry entries
reboot
Are there particular .dlls or anything else I need to remove that the uninstall process might leave around that would cause trouble, such as .dlls? I've searched specifically for bzip2.dll, and there is a copy associated with another program in a program-specific directory (\Program Files\EASEUS) unrelated to gimp.

When I run the install (using normal install, although custom fails as well), it appears to install correctly. However:
It does not create a desktop shortcut (Should it, in the default install?)
It creates only a single entry in the start menu, labelled "GIMP 2". In particular, no subitems, such as uninstall (should it?)

A possible issue -- this is running booted from an "F:" drive, with no "C:" or "D:" drive on the machine.

Reinstalling GIMP 2.7.5 works fine: creates a desktop shortcut
creates a start menu item with three subitems Gimp-2.7.5, Uninstall, Website
loads and runs fine
I don't know how closely the 2.8 rc1 install should mirror 2.7.5

Thanks for any insights...
