Understandable. Be sure to convert the jpg files to Tiff BEFORE
converting to CMYK. You really should use a bitmap editor like
Photoshop,(It's specifically used for print offset colour work)
as you probably will need to think about colour profiles, if
going to lithography offset. Print colour conversions is more
than simply converting to a different format, in most cases other than
when doing two colour utility printing.
Does the printer not have a colour profile for you to use ?

Of course not, GIMP is not an application for CMYK.
