How do I rescale an image without changing the stroke ratio?

[kitebiker]

I received an illustration from a client and I need to enlarge the image for printing. They have imbedded many different stroke sizes in one illustration so I cannot just choose those strokes and set one stroke size. When I enlarge this image the lines come out thin and changes everything about the image. How can I change the size of the image keeping the same stroke ratio.??
TIA

...scale stokes and effects needs to be enable, select all, double click scale tool and have the option enabled in the dialog...

...it is also found in the flyout menu of the transform palette...

You can also set the option to scale strokes (and effects) in the general program preferences.

...yes, the preferences too, the option in the transform palette flyout menu is linked to the preferences dialog, turn it off in the transform palette it also turns off in the general preferences...
