Preparing an Image for the Inkjet or Laser Printer

While not everyone has access to a 4-color press; even casual computer users have or have access to, an inkjet or laser printer. Inkjet and laser printers apply ink to the paper using dots of color. In fact, one of the measurements of quality for this type of output is its printing resolution. For example, a photo-quality inkjet or laser printer can run with a resolution of 1,400dpi and higher, or one thousand four hundred dots of color information per linear inch. There are several file format options for output to print, however none is so versatile as the TIFF format. The Tagged Image File Format, uses lossy or lossless compression, and lets you save multiple Photoshop layers, as well as alpha channel information. In addition, there is hardly a layout application in the marketplace, Macintosh or Windows, that will not open a TIFF saved image.
