A preview of the target is displayed and it is possible to customize the pattern format using the "**Edit target format**" tools. If your test chart is not already printed, you can export it in Tiff or pdf format to print it. Click the "**Next**" button to continue.

The control of an RGB Mediawedge range is very similar to that of a CMYK Mediawedge. \
You can use the tutorial "Controlling a standardized Mediawedge range" starting in the chapter "[Importing a Print Control File (.pctrl)](https://docs.coraye.com/untitled#import-a-print-control-file-pctrl)"
