There are two basic types of design formats which effect the overall performance of your logo.
- The Raster Image file
- The vector file
Why the difference and how can you determine the proper type too use?
RASTER GRAPHIC FILES
To begin we need to ask – what basically is a raster file?
These can also be referred to as bitmaps. The image file is has a number of pixels or little bits of “boxes” which form the image we are looking at. The most common types of these files are jpg. gif. png. mp4. tif. [tif files contain lots of information making for large file sizes]. You can read more about Types of Bitmaps Here.

Common programs that use this method of design are but not limited to Adobe Photoshop, Corel Painter, Corel Paintshop Pro, Gimp, Art Weaver, Kitra and others.
Each pixel contains some colour information [RGB] that when looked at from a distance the pixels “blend together” giving a clear crisp appearance. When you zoom in to view the photo you see the boxes containing colour information.
When we have an image that is not high in resolution, when it is enlarged the pixel boxes become noticeable providing a poor or seemingly out of focus appearance. So it important to have a resolution or quality of at least 300 dpi [dots per square inch] The lower the quality results in a larger dot or box. So the higher your resolution the more boxes or “dots” contained within an inch of space. This increased information will also increase the size of your file even if it was the same size of a lower resolution image.
this is an image at with a resolution of 300 dpi
this is a zoomed in view of the 300 dpi resolution image.
this is a zoomed in view of the same file but at ½ the resolution [150 dpi]
To begin we need to ask – what basically is a vector file?
These files are computer generated to provide clean lines without the worry of pixels affecting your design.
Vector files have what is referred to as points connected together by lines. These lines which have points anchoring them together can be scaled to any size. the size can be either considerably larger or smaller without compromising the look of your logo.
Common programs that use this method of design are but not limited to Adobe Illustrator, CorelDRAW, Sketch, Affinity, Designer, Inkscape, Adobe Illustrator, Draw, DesignEvo, Vecteezy Editor, Xera and others.
The file types are recognized as ai. cdr. eps. svg. pdf.
Vector files can be opened again and edit any part of the file including any text you might have in it. However, when compared to a raster file, all text is part of the image and cannot be directly edited again once the file is saved as an image.
The file sizes do not become affected as with raster (image) files. Usually vector files are smaller in size compared to image files.
this is a vector file rendered and not rendered. Notice there are no pixels just connected lines.
Later we will address what is the best method to use.
I hope that this post was simplified and easy to understand. I will attempt to keep all future posts uncomplicated and easy to follow.
