If your artwork size does not match the chosen paper size, you will need to choose one of the 'Scale artwork' options on the configure page.
Scale To Best Fit
Choose 'scale to best fit' to ensure the artwork is scaled to the largest possible print size.
Depending on image quality, pixelation may occur. We recommend using images with a minimum resolution of 300 dpi.
Depending on the artwork size/proportions and required print size, white borders may be added to the final artwork.
Do Not Scale
If you would like your artwork to be printed at actual size on your chosen paper size, choose 'do not scale'.
This means that your artwork will not be resized to best fit the paper size.
