Canvas printing

I was thinking of trying a canvas print with one of my pics and do not know how the file should be...other than in jpeg.
For the web - or on here - it's a small size about 800 kb on long edge and I reduce them to a resolution of 72. I also sharpen.
BUT do things have to be different for printing ?

I have only tried TESCO ( canvases were 1/2 price)) and they do not know a thing so I thought I would see if anyone has been through the process.
Thanks

Re: Canvas printing

Use the full size file as a jpeg in the srgb colour space and make sure you crop it to the size of the canvas print. If you leave it for them ( the machine) to do the cropping you may be disappointed with what they have cut off to make it fit.

Re: Canvas printing

The ideal resolution for printing is 300ppi, but 240 is OK. As Paul says, size to actual printed size or a fraction larger, and if you are cropping allow for 25mm or so each side extra for the wrap-around.

I use Snapmad and they are very good and have useful info re sizing etc.

Re: Canvas printing

I've used Tesco, and to be fair to them, they sell canvases, not advice on printing dpi's. Use 300 if you can for large format canvases, and they will come out fine. I've sold 5 canvases I've had done in tescos as jpg's at 300 dpi.

Re: Canvas printing

Hi

You need to keep your photos as 8 bit jpeg of tiff in SRGB colour space.

I have also used snapmad quality is good and turn around time and prices excellent.

Here is some info you may find useful regarding preparation of images and resolution.

canvas prints
size (in) quantity resolution
1+ ok optimum
12 x 12 17.99 2175 x 2175 4350 x 4350
16 x 12 22.99 2775 x 2175 5550 x 4350
16 x 16 23.49 2775 x 2775 5550 x 5550
18 x 12 22.99 3075 x 2175 6150 x 4350
20 x 16 23.99 3375 x 2775 6750 x 5550
20 x 20 24.49 3375 x 3375 6750 x 6750
24 x 16 23.99 3975 x 2775 7950 x 5550
24 x 20 24.99 3975 x 3375 7950 x 6750
30 x 12 24.99 4875 x 2175 9750 x 4350
30 x 15 24.99 4875 x 2625 9750 x 5250
30 x 20 29.99 4875 x 3375 9750 x 6750

http://www.snapmad.com/faq.php

I've had a few 30in x 20in at 300ppi which come out at about 155MB, you upload to snapmad's site which is about 10 - 15 mins it all works smoothly.

Give them a try, I think you'll be pleased with the results.

Regards

Tom
