official FINAL TRIM SIZE & OPTIMAL FILE SIZE FOR FULL BLEED IMAGES (8" x 10" Portrait SOFTCOVER)
in regards to a 8” x 10” Portrait SOFTCOVER book
Please advise if is this 100% correct.
part A)
FINAL TRIM SIZE
final TRIM size (of the 8” x 10” Portrait SOFTCOVER book) is:
w: 7.775” x h: 9.75”
width: 7.775”
(which is 7.9”, less a 0.125” bleed trimmed off the non-gutter side)
height: 9.75”
(which is 10”, less a 0.125” bleed trimmed off the top, and less a 0.125” bleed trimmed off the bottom)
part B)
OPTIMAL FILE SIZE
optimal file size for a FULL BLEED IMAGE is:
w: 2370 pixels x h: 3000 pixels
width:
a full bleed image of EXACTLY 2370 pixels (7.9” at 300 pixels per inch)
height: 10”
a full bleed image of EXACTLY 3000 pixels (10” at 300 pixels per inch)
note 1:
In BookSmart 1.9.1, the software asks for a file:
w: 2363 pixels
which is 7.877” at 300 pixels per inch — an odd measurement ?!
It seems optimal file should be
w: 2370 pixels
Unless of course we are going off metric measurements.
In that case, 2362 pixels is a nice clean measurement of 20 centimeters on the nose.
And 2362 is just one pixel shy of 2363.
I realize that this is splitting hairs…
But I want to set up my InDesign and Photoshop templates correctly.
note 2:
This is a guess.
The reason the
w: 8” x h: 10” softcoverbook is trimmed down to w: 7.775” x h: 9.75”
is so that the trimming of the softcover pages is the same as the trimming of the hardcover pages (which has pages smaller than the exterior hard cover.)
Correct?
Thanks in advance.
