JPEGs and transparency
Today I had to make a web banner, animated GIF, and it needed to be done in half an hour. That’s OK if you’ve got all the “ingredients” and know what you want to do, or have been told what the animation should do or say. I had a problem though, the client wanted a logo on a blue background but they only had a JPG of the logo, it was therefore in a white square because JPG doesn’t support transparent regions. The white background can be erased in photoshop but it’s not always a quick job. Anyway we settled on having the logo on the far left in it’s white space seperate from the rest of the blue backgrounded banner.
The best kind of logo for the studio to have is usually an “.EPS“, it can be scaled to any size and have transparent regions if necessary. Whoever created your logo originally should have supplied an “.EPS”, it’s also essential for print jobs where you might want to scale up the logo to fit the side of a bus, for example…
Various format images of logos placed on a background
In the example above you can see the nasty results in full of an inappropriate file format for a logo! If you work in the design industry you’ve probably been supplied a logo as a JPG someone has pulled off a webpage somewhere. Then the client requires it placing on a complex photo background or enlarging to be printed on the side of a skyscraper. Two other side-effects you can see; washed out colours and rough clipping in Quark (or most programs that can auto-clip images/backgrounds).
