Create file with multiple pages rather than one page per file. Create document as single pages, not reader's pairs or printer's pairs. Supply Laser copies of your document with color break and noted. There are several types of images that may be placed in page layout documents. Bitmaps can be black and white, grayscale or color.
Tiff files are high-resolution bitmapped images.
Tiff images can be very large files. They also cannot be resized without a change in resolution. Photoshop uses the term bitmap to describe a black and white image. The number of pixels per inch in an image is called the image resolution. Resolution should be determined when the image is created or scanned.
