Hi Richard,
Thank you for you help on this matter.
I will try the exporting and adjusting the images to see how work.
On the cut of the last letter/image, the previous sample maybe don't show clearly, see attached PDF with other sample of cut images.
UPDATED: Richard, I check the size of the "N" and "Y" image and they are same width (2.727" and 818 px).
I dont know how to provide you with the name of the Expression for you to test, I can sent you a link with all the files I have for that job.
Thank you for all your help,
