I made a DL flyer, that fits 3x into A4 (= 210x99mm). My client gets taxed for the printer merging one DL flyer to fit the page 3x, so now he asked me to to it.
I am now struggling on on how to fit theese DLs without crop marks going "off". It cuts the first and last on different places and the middle one stays untouched (see attached picture).
Sorry for the absolutely newbie question, but I never really needed this and now I'm lost.
Thanks in advance for any advice
You've forgotten to allow for the bleed. You can't fit this full-bleed 3-up on A4.
Presuming 3 mm bleed all around, each one needs a minimum of 216 x 105mm of printable area on the sheet. This cannot be done 3-up on A4.
