Vector vs Bitmap Images
This type of file is resolution independent which allows us to scale the image proportionally to any size or resolution and still display exactly as they were drawn without losing quality/detail or clarity. Vector files allow us to create a clear final print and also enable us to create colour separations.
Vector graphics use mathematical relationships between points and the paths connecting them to describe an image. These objects are defined by mathematical equations rather than pixels, so they always render at the highest quality. Objects consist of lines, curves, and shapes with editable attributes such as colour, fill, and outline. Vector images are crisp illustrations, with distinct outlines and fills.
Vector image formats that are acceptable :
Vectorised .EPS files
Adobe Illustrator .AI files
Vectorised .PDF files
Vectorised .SVG files
Programs Used To Create Vector Files:
Adobe Illustrator, Affinity Designer, Corel Draw
Bitmap images (Raster) are made up of pixels in a grid. Pixels are tiny dots of individual colour that make up what you see on your screen. Images that are created and edited in Photoshop for example, are referred to as bitmaps because they are made up of a series of pixels; resizing a bitmap to a larger size causes the bitmap image to appear rougher (Pixilated) than a vector graphic and file sizes tend to be larger because of the many square dots.
Because bitmaps are resolution-dependent, it’s difficult to increase or decrease their size without sacrificing a degree of image quality. When you reduce the size of a bitmap image through your software’s resample or resize command, you must throw away pixels. When you increase the size of a bitmap image through your software’s resample or resize command, the software has to create new pixels. Website-quality images are definitely not suitable for any print media.
Typical BITMAP image formats are:
- Jpeg .JPG files
- Bitmap .BMP files
- Embedded .PDF files
- Microsoft Word Files
- .TIFF or .TIF
- .GIF files
- .PPT files
- .PNG files
Programs Used To Create Bitmap Files:
Adobe Photoshop, Affinity Photo, Microsoft Word, Internet Images, Powerpoint
