/ File types Which files should you send to print? You are best off saving vector artwork (the sort of stuff from Illustrator) as an EPS, PDF or AI file. In this photo from the Print Handbook you can see why PDFs (bottom left) and EPSs trump TIFFs and JPEGs every time for vector stuff. Even at 300dpi the TIFF and JPG don’t handle this vector graphic nearly so well. They have to convert it to pixels, and in this situation it shows. Bitmaps TIFFs, JPEGs and even PSDs are what you should be saving
your bitmap files as (the sort of things created in Photoshop). TIFFs and PSDs are lossless. You don’t lose any quality by saving a file as a TIFF or PSD. JPEGs normally lose quality when you save them but take up a lot less space on your computer. A very high quality JPEG is often not a lot different to a TIFF or PSD, but it does very much depend on the sort of image you’re saving. A TIFF or PSD is normally a better option than a JPEG. But if you’ve been supplied with a
JPEG, from a camera or stock photo website, and you’re not modifying the image then you will gain nothing from saving it as a TIFF or PSD. A TIFF or PSD cannot create detail where there was none in the first place. But a JPEG can remove detail where once there was some. There’s a couple of thing to notice in the pictures here related to JPEGs. Firstly, JPEGs can’t handle spot colours. So when this JPEG was saved it converted the Pantone colour
