files who couldn't answer the above questions and we end up having to recreate their artwork.

Answers:

1. Vector art is artwork created in a drawing program such as Adobe Illustrator. All images must have outlines around them in order to be vectored artwork. These outlines are represented by mathematical formulae that allow the images to be enlarged to virtually any size and still be printed at a high resolution. That is what resolution independence is the ability to scale a graphic to various sizes and still retain high image quality. Scanned images and digital photography (bitmap images consisting of pixels) are not resolution independent, depending on the output device they can only be printed to a certain size and no larger.

2. File resolution limits final print size for all bitmap images (digital photography and scanned images). If you print RIP requires 100 pixels per inch then the final print size of a file 2569 pixel x 3678 pixels is 2569/100 x 3678/100 or 25.69" x 36.78" and not larger unless you are prepared to live with pixelated and otherwise degraded final images.

3. To use a 35mm slide you would have to severely crop the image and scan it at a very high resolution 1400 pixels x 15000 pixels. The example slide at right show a red box that is the proportion of the 14x150 inch header. As you can see most of the image area of the slide is going to be unavailable for the header proportions. That red rectangle representing about 15% of the total slide would have to be scanned at 1400 pixels x 15000 pixels in order to be printed at an acceptable resolution.

4. A 150 pixel x 150 pixel image could only be printed 1.5" x 1.5". Not nearly large enough for trade show graphics usage.

I suggest that if you don't understand those questions and answers above that you pay someone to do your computer layout for you. You'll save time in the long run and perhaps even make your deadline.
