A InDesign files can be made from Quark on the internet
Converting Quark to InDesign on the internet will give you the basic’s. Colours, images and lots and lots of text boxes. The layout will still require artworking and proofing. The file can be polished, as an Artworker I would still start a layout from scratch as you don’t know what nasties lie within. Giving you a clean and tidy file for print.
