You need to take your Printer's bleed into account.
For instance, an 8x10 print size with bleed on a DS80 is 8.16"x10.12", which will noticeably crop with a precise layout.

Use the Print Offset Control to adjust your bleed size. If your print is cropping, reduce the bleed size to a negative value. The bleed size value is in pixels. 38px is about 1/8".
