Since it is always appropriate to congratulate "something", we propose a simple layout exercise.
On a vertical A4 document at 180 dpi, we make a division into three thirds (using guides, for example).
We will work on one third, creating an image with text. After merging the visible layers, we select, copy, go back in history and paste twice.
By cutting a third of the document, we will also have a lightweight digital output of sufficient size to be sent without any problem.
