Vector vs. raster files, what should I need?

We found out, that many people do not know what is the difference in graphics files and which ones the actually need. So let us clear this mysterium.

Raster file - GIF, PNG, BMP, JPG, ...
These file formats have one thing in common - the picture is divided into a small slices - pixels - and for each and every this little spot there is a piece of information.

It has many advantages - all graphic and non-graphic software and other non-computer devices supports at least one of this format, there is very easy work with it, so creating raster image is very fast.

Only one big disadvantage is there - you cannot magnify it. If you magnify the image, you get only set of cubes, because the small points creating the images become big ones.

Vector file - SVG, AI, EPS, DXF, ...
Vector files are made of vectors (= line with some coordinates), so every object made of vectors is also made of coordinates. So if you have a cube, there are coordinates of all lines, points and their relative position to other objects.
So if you want to see the result, your graphical software has to read all this data, calculates the space and objects and draw them.

The big advantage of this format is that you can magnify the image indefinetly. As you magnify the line, you will get more details and at the end, online big lines are shown. All lines are clean and not blured as in raster.

The main problem with the vector is the work with them. So you need special software and all development process is very slow. If you put some raster object, you have to trace it to vector, etc. Also vector files are unusable for very complex images as photos, because big amount of data.

Conclusion
We are so cheap, because we can work very fast. So that standard logo design input is the raster file. If you need your logo for printing, we will provide the file with very big resolution like 2000 pixels, which is also sufficient for printing.

We can provide our customer vector files, but as this work is more complicated, it cannot be included in the price of the cheap logo design packages.
