transparent background on a JPG

[pagetta]

Hi I am making an advert we had published into a file to be printed on clear acrylic for our board room, so as a result I need there to be no white background, but all clear background.

The problem is that I have a large picture within the advert, and want this to have rounded corners - but whenever I save it, I cannot get the background to save transparent so it has little white right angle corners on it that I can't get rid of!

What format can I save this in to get a transparent background?

thanks :-)

Hi,

not sure what you are trying to accomplish. You want to print this, so why are you saving to .jpg?

What program do you work with?

Hi - sorry to cause confusion faglork! I have found an answer now - transparent PNG - doh! I am not used to designing for printers!

Just in case you want to use the .png on your website: you have to take care of IE's problem with alpha transparency:

Depending on your printer, you could also save it as a .AI, .EPS, or in a lot of cases even a .PSD file now. This would allow you to preserve the transparency and give your printer a vector art image to work with (unless you're feeding the acrylic through an actual colour printer itself.)

Thanks Adam - its actually a photograph I was having issues with - the rest of the advert we're having done is all vector so was no issue, but the image had rounded corners and need to save it transparent so that the little white sharp corners weren't there - its being printed digitally then put onto a 5mm acrylic sign by some local sign makers.

Transparent PNG did the job though!
