Should I also offer a downloadable photo PDF?
Not as the table menu: a PDF with photos goes stale and weighs a lot. Yes, only on the day the printer or a group asks for a closed file, exported from the current cards. In Madrid the photo PDF and the QR fall out of step, and the price in the printed image no longer holds. The table stays on the QR cards, and the PDF, if it goes out, is exported that day from those same photos.
