44 • A&E SEPTEMBER 2019 CORELDRAW: THE BASICS By Doug Zender Doug Zender has used CorelDRAW extensively since version 4. His goal is to minimize the intimidation of the program and give users the sense that CorelDRAW is a friend, not an adversary. Doug began as a design artist, then moved into the sign industry in 1992 doing vinyl graphics. You can contact him at Fig 1 Save and Export Abilities in CorelDRAW W e last looked at some of the open and import abilities of the CorelDRAW program (August issue, page 70). I want to focus here on a few of the many save and export abilities. Many times we create a quality design that our client decides he wants to use in all his advertising, for example, yet can't use a native Corel file. It is then necessary to provide the design in a file format that is easily reproduced. In these cases, it is good to know how to make our design compatible with whatever file type the recipient requires. Generally, a PDF file is the best choice since it is most universally accepted, but some entities ask for a specific file type other than PDF. For instance, an online printer that I've worked with requires a TIFF file at 1:4 scale in the CMYK color space to produce a printed banner. DIFFERING FILE TYPES It's best to understand the nature of dif- fering file types. JPEG, PNG, TIFF, etc. are all raster image formats that do not support vector objects, but only bitmap files. Each of these have their own abilities and limitations. • JPEGs (Joint Photographic Experts Group) can be either CMYK or RGB color space, but do not support trans- parency (hence always have a "white box"). A "lossy" bitmap (compres- sion removes details), JPEG sacrifices clarity for small file size. • PNG (Portable Network Graphics) supports only the RGB color space, but supports transparency while retaining a relatively small file size. A "lossless" file type, it is often the preferred choice for bitmaps. • TIFFs (Tagged Image File Format) support both CMYK and RGB color spaces and can support transparency, but tend to be large files as compared to other formats, though they are a "lossless" bitmap file type. There are numerous other bitmap for- mats, but these three are most common. Figure 1 shows the JPEG dialog — others are similar.
