You could possibly choose to implement coating either on either side or just the front facet of your custom made flyer. Uncoated flyers are writable, but if you want to compose on coated flyers, we propose you employ long-lasting markers. We print in RGB; not CMYK like most other printers. https://flyer-printing83940.pointblog.net/the-best-side-of-flyer-printing-86466813
