To output my final pieces I have decided to use Indesign (Id) and output as a PDF
I set up a template and inserted my images using the “place” command. Chose a font and I titled them.
Regretably I noticed that after processing a number of images that Id had defaulted A4.
As PDF is a vector file I wondered if I could be lazy and just get the pdf printed at A3.
After some thought, research on bulletin boards

Advice from the forum on creating PDFs for print
Any images/photographs should be in TIFF format, or maximum-quality JPG and at a resolution of 600dpi
Your artwork should be output as a (vector) Press Quality PDF (with embedded fonts and images).
Final artwork submitted to us should be created suitably for high-resolution 4-colour process lithographic printing.
Additionally dpi is defined as the number of dots in a linear inch.
