, we will print the file without any kind of enhancement or scaling
To know if the file is good please download it and open it on a pdf viewer like Adobe pdf viewer
and set the view level or zoom level to 100% or 1:1 or
full scale or actual size, depending on which version or pdf viewer you are using. Also, using the measuring tool
make sure all the parts fit together and have the correct size.
We can scale the Cobra 21 or any other PDF plan for you. But please keep in mind that if this plan is not vector, if you enlarge it too much the quality will be degraded.
