The Colorway print can only be printed from the Thumbnail view.
When you want to print the Colorway - you have to select one of your Colorprints in the print pop-up. Once selected you can decide if you need to print all types of data fields.
You can de-select the ones you don't need.
When you are satisfied with your selection - click on OK and the Colorway will appear as a PDF preview.
Each page can display 12 colors and 6 style files - in case a Style has more than 12 colors these will appear on subsequent pages.
Save the PDF to your desktop or print it.
