too large to print?

[Spittinimages]

I need to print a large canvas 48 X 36 gallery wrap so I added 2 inches to all 4 sides. Now we have a 52 x 40!

So I attempted to place an order at 300 dpi and it was not accepted - too large. Dropped down to 240 dpi - still too large. Width 12,480 pix x 9600 pix.
Pixel dim 342.8M. The canvas Labs limitation is 10,000 x 10,000. They are no help.
I can lower the dpi further but I don’t know how far to go till I get a pixelated image.

I am in uncharted territory here (never needed print this large). Any suggestions? Anything jump out at you that I might do?

Any help would greatly be appreciated.

Which printer do you want to use for that 48x36 gallery wrap ?

Mostly when I put a print on Canvas, I deliberately alter it to use 72 DPI, on such a rough surface it looks much better to me..

@Spittinimages : there’s something that I didn’t get clearly.
Is it 12480 x 9600 pix the original size of the image that you intend to print or else you obtained this size after resizing the original to 48x36” while keeping the same dpi. ?

Assuming that the original file is indeed 12480x9600, the points to consider are :

1- The aspect ratio of a 12480x9600 pix image is 1.30, but a canvas of 48x36 has an aspect ratio of 4/3 (1.33 ).
To print exactly 48x36” you need to crop a bit the short side of the image, reducing it to 12480 x 9360 pix. If you don’t want to crop anything then the printed area will be 46.8x36” leaving some extra margins on the longer side.

2- If you start with 12480x9600 pixels and Canvas Labs limits are 10000x10000, you need to downsize the longer side of your file to 10000 pix. That gives a 10000x7692 pìx or 10000x7500 if you cropped the original to 12480 x 9360.

3- To fit 7692 pix in 36” the resolution must be: 7692/36 = 214 dpi
If you cropped to7500pix, then it’s 7500/36= 208 dpi.

Printing an Image of that size will never be a problem at 72 dpi or lower, the minimum viewing distance is going to be at least 1 metre or even greater and it will enhance your image further and open it up..

Wow - thank you. Gonna try it.

Decided to go with a lower resolution - which of course is no problem I'll report on how it works out.

I have printed that size many times. Since I mostly work with artists reproducing their work, I always print 300 dpi files.
The questions you need to ask are what is the ink set. Are you okay with Aquous where the print will need to be coated, or would you rather use a latex or solvent based ink which would be okay without coating. Are you stretching?
I recommend a thicker strainer [stretcher], so 2 inches of printed edge and an additional 1 inch to grip.

Anyone with a 44 inch printer should be able to print this size. Using a transfer such as wetransfer.com will solve the file size issue.

Yes viewing distance is important. Hell Billboards are somewhere near 25 dpi. But the 3 x 4 foot is small enough that a viewer may want to go right up to look at the detail.

Stay with 300 dpi and find a printer able to do this for you.

There are Some billboards less than 1 dpi.. Nosy parkers can't see the forest for the trees..
300 dpi works in your hand, but not on billboards...
