Chances are you'll choose to use coating possibly on each side or simply just the entrance side of your customized flyer. Uncoated flyers are writable, but if you need to produce on coated flyers, we recommend you employ everlasting markers. We print in RGB; not CMYK like most other printers. https://flyer-printing16893.celticwiki.com/1914917/the_best_side_of_flyer_printing
