Real-world capture dependent on lens and hardware quality.

• Pixel-based

• Raster programs best for editing photos and creating continuous tone images with soft color blends

• Do not scale up optimally - Image must be created/scanned at the desired usage size or larger

• Large dimensions & detailed images equal large file size

• It is more difficult to print raster images using a limited amount of spot colors

• Some processes cannot use raster formats

• Depending on the complexity of the image, conversion to vector may be time consuming

• Raster images are the most common image format, including: jpg, gif, png, tif, bmp, psd, eps and pdfs originating from raster programs

• Common raster programs: photo editing / paint programs such as Photoshop & Paint Shop, GIMP (free)

Image representation of the real world down to the skill of the artist/draftsman.

• Shapes based on mathematical calculations

• Vector programs best for creating logos, drawings and illustrations, technical drawings.

For images that will be applied to physical products.

• Can be scaled to any size without losing quality

• Resolution-independent: Can be printed at any size/resolution

• A large dimension vector graphic maintains a small file size

• Number of colors can be easily increased or reduced to adjust printing budget

• Vector art can be used for many processes and easily rasterized to be used for all processes

• Can be easily converted to raster

• It is not the best format for continuous tone images with blends of color or to edit photographs

• Common vector graphic file format: ai, cdr, svg, and eps & pdfs originating from vector programs

• Common vector programs: drawing programs such as Illustrator, CorelDraw, Inkscape (free)
