I have been trying to find a lab that can print a large panoramic for me. All of the sites that have an upload feature have given me errors or are not able to handle my image size. does anyone know of a lab that can print a 3994 x 233 pano besides banner printing companies?

From WHCC website:

Q. What is the largest size you can print and mount?
A. We can print 30" wide by 12 feet long. We commonly make prints to 96" and longer. We do not mount prints larger than 30x40. We only texture prints up to 24x30 and lustre coating no longer than 60".

Big enough? -Brian

I assume those are pixel dimensions (3994 x 233 pixels). That is not a particularly large (in terms of pixel numbers) image. What resolution are you using to get your final physical dimensions? For example, if you printed your file at 150 ppi, then the physical dimension of the print, in inches, would be:

3994 pixels / (150 px/in) = ~27 inches in the long dimension. Note that at 150 pip, the small dimension will be only:

233 pixels / 150 px/in = 1.5 inches tall.

Is this what you are expecting?

Sorry, I forgot the image was compressed. The original image is 18100 x 1056 pixels.

Would 150ppi look okay or should it be at 300ppi or higher?

Many labs state that they need 300 ppi to print a given pixel count to a given size. So if we want a 45x30" final size, they want a file of 13500x9000 pixels.

As to the 'would 150ppi look OK...?', the response is simply "When viewed at what viewing distance?!".

  • If I look at a 150ppi print from 40" away, and I look at a 300ppi print from 20" away, the two prints will appear to be identical in quality.
  • If I look at both from 20" away, I probably can discern a difference in quality.
  • If I look at both from 100' away, I might not be able to discern a difference because it is human vision which is the limit to 'quality'.

I chose 150 ppi arbitrarily, simply because 240 ppi or 300 ppi would have made the image minuscule at the pixel dimensions originally cited.

Bottom line - what size, physically, do you want the print to be? With very long and narrow panoramic prints, there are factors that make printing a trade off. Are you going to frame this? If so, what are you going to do - try to find a stock frame, or have a custom frame made? Because the image is very wide compared to height, at some point the height of the image will be so physically small that height will probably drive the choice of dimensions. So, let's say you want your image to end up being 8 inches tall:

for an 8 inch tall image at 300 ppi, you need 2400 pixels in the image height dimension. Currently, according to your post, your original does not have the necessary pixel dimension (you stated that your original is 18,100 px wide by 1056 px tall). If you choose a print resolution of 300 ppi, then the maximum height your print can be, without adding pixels artificially is 3.5 inches. if you print your current original at 300 ppi, your panorama will be:

60 inches (5 feet!) wide by 3.5 inches tall.

Is this what you were envisioning? Very wide and not very tall. At 240 ppi, you would get something like:

75 inches wide by 4.4 inches tall. In your case, the aspect ratio of your image is like 17 to 1, so your attempt to make the image taller will necessarily make it really wide, and attempting to make it narrower will necessarily make it really short, regardless of what final physical size and resolution your print.

That being said, you need to contact the lab that will ultimately print your image and have them specify the requirements for the final print size. I have had a 20 foot wide by 8 foot tall equirectangular panorama dye-sub printed on fabric from an original that was 14kpx wide (the aspect ratio of an equirect. pano is 2:1, so that the top and bottom was cropped). I had to upres the image for the printer, but the combination of the printer resolution and the viewing conditions worked out well, even at very close viewing distance. So, work with the lab and see what they require.

My R2880 will print at 13" and as long as I want it on roll paper, so the technology exists "out there".

My own experience tells me not to try and stretch those pixels too thin. Why not try an A4 print of a section at a variety of different PPI and make up your own mind what you are happy with?

You do seem to have a problem getting enough resolution to get a decent height for the image.

What print dimensions (in inches) were you asking for?

Without desired print dimensions you won't get any useful advice. Any lab can print your 18,000 pixel image as a 6x4.

If you've got it at 150ppi that's 120". I don't see a problem with that, any pro lab should be fine with it.

Contact this member here on POTN. He did some huge prints for me a while back and they were amazing. His name is John.
