Oftentimes, designers won't know that there is a distinct difference between how you can use the program for one project as opposed to another. Web design, for instance, requires different talents and knowledge than does CD-ROM interface design. And using Photoshop for printing purposes can be an entirely different beast altogether. This month, I'll go into some of the technical and aesthetic aspects of using Photoshop for developing print work. Basically, the higher the resolution, the more pixels there are in an image, and the better the overall detail.
Lower resolutions result in a reduced number of pixels, and lower quality in terms of detail.
Also referred to as the image resolution, this measures the number of pixels per inch in your image. The more pixels that exist in each inch, the more detail that will exist in your work. More pixels per inch, though, will also equate to a larger file size. You can usually expect that a monitor will display 72 dots per inch. In this case, your image will appear three times as large when viewed on screen at 100 percent.
