Anyone explain this?

i've just produced some images for my showroom to be printed onto canvas and then hung on the walls with weighted bottoms.

i wanted each image to be 120 x 60cm, so the images i gave to the printer were exactly twice the height as the width in pixels.

he's printed the first one as a tester and it has come out at around 118.5 x 65cm, yet he hasn't cropped, resized or edited the images in anyway?

he doesn't know why they measure this and neither do i? are we missing something obvious or what could be reason for this?

i told him i don't mind those dimensions... as long as the other 5 are the same size so i can hang them next to each other - but he's not confident that they will be :shrug:

He may have hung them to dry wet and they have stretched :shrug:

Alternatively the print driver may have just stretched the image. He cannot say he hasn't resized it as it is resized and this has either been the software, him inadvertently doing it, an error or the material stretching.

Please correct me if I'm wrong, but you probably sent an arbitrary resolution file which doesn't map to the native resolution and DPI of the printer (which may well be different in X and Y directions). So the printer driver / rasterizing processor will scale your image anyway, but it should definitely keep the aspect ration and be able to print to an exactly specified size. Unless of course the material has somehow stretched like Darren suggested.

I wouldn't easily accept an almost 10% change in aspect ratio.. at least not if I paid money for the print. I suspect the problem is with the operator's skills and not the machinery here.

Maybe this is a dumb question i don't know but do his printer print at 2:1 ratio at that size? Iv'e never had big canvas prints done but when i get smaller prints done there is only specific sizes that they print at and i have to accept only the sizes they offer...

well, he is a commercial printer and prints on his own (what i can only describe as...) massive press!! He works from the unit right next door to mine and has done all my general printing stuff, so that's why he offered to do a 'test run' on the first canvas to make sure i'm happy with them. the only thing now is... will the others be the same size? suppose that's his side of it to sort out.

here's the first test one (taken on the mobile phone)
