How to get a water-fast print from inkjet printer?
The water-fastness depends on the ink and the receptive coatings. Once printed, the dyes in the ink will slowly react with the chemicals in the coating and eventually get fixed. Try not to use photo printing mode when excess dyes that do not fully react with coatings might easily be washed off when getting in contact with water. In addition, please allow enough time after printing before it exposes to wet weather. The MagnaSignTM is coated with special receptive coatings that will gradually react with the dyes or pigments in the ink to provide water fast prints. Because the reaction proceeds slowly, so it usually takes up to 48 hours before all the dyes and pigments fully react with the coatings.
