File Output (vers. 6)

Here you can choose what kind of file you have in the preview. The preview is basically an image in the editor of the print PDF.
You can choose here between JPEG, PNG or transparent PNG.

JPEGs are for photographs and realistic images if you have them in your print file. PNGs are for line art, text-heavy images, and images with few colors.
If the background of the print file shouldn’t be white, you can use the transparent PNG option.

If you use Live Preview, please use PNG Transparent.
