Metamark Flag is made from 90gsm fabric, and with a fine net type fabric offers a high 'strike through' of the ink to provide double sided banners (the reverse image is mirrored). It has a removable release liner, stopping the ink and providing rigidity when printing. It is flame retardant and can be used indoors or outdoors. Note: This product has very low ink limits so where a correct profile is not available, a generic profile with low ink limits shoudl be used to avoid ink bleed.
