Postcard Jason friday the 13th Have a killer Birthday with Jason Voorhees from the FRIDAY THE 13th series is printed with risograph on 300 grams Gmund paper. And extremely suitable for every horror lover. This fun birthday card is too funny and will certainly put a smile on his/her face with every recipient. Studio Inktvis has fallen for RISO because of the intensely richly colored prints it produces. The RISO printing principle is therefore very similar to screen printing. The final print looks handmade or beautiful, not perfect. The process is also eco-friendly. The ink is based on fairly produced soy oil and the masters are made of Japanese wax-coated paper. The machine uses very little energy because RISO printing is a cold printing process. The postcards in the FUN NEON series are all available in A6 format. The dimensions of this are 105 millimeters x 148 millimeters. Gmund paper is used. The weight of the paper used is 300 gr/m2.
