we want this to be clean and professional as if it was being published by a larger publishing company.
Your expected cover size is 12.552x9.250. Your cover file should be a PDF sized sized with bleed and no surrounding white space or crop marks. If the file is sized at dimensions other than those expected, Print Previewer will note the discrepancy and prevent approval.
To correct this issue, check the following:
Set the width and height of your file to full cover size according to our File Size Calculator.
There should be no white space around the edges of the cover file or it may fail for bleed.
All images or backgrounds meant to reach all the way to the edge of the page, must extend 0.125” (3.2 mm) beyond the trim line. If it does not, it will be rejected.
Images or graphics that shouldn’t reach all the way to the edge of the page must fit within the safe zone, which is represented by the dashed red lines in Previewer.
All text must fit within the safe zone.
