Hi there,
When printing an A1 image from layouts at 350dpi, it prints not at 894 x 541 350dpi, but at 2887x4088mm 72 dpi.
Unlike printing from the model space which maintains the chosen DPI, the layout space converts it to 72dpi equivalent.
The problem with this is that when I place the image in indesign; expecting it to be to scale, it appears enormous.
