This is a three color Riso print in yellow, fluorescent pink and blue ink. Print percentages are listen on the back side of the print, handy for Riso printers! Hand printed by Natalie in her Los Angeles studio. Size is 8 1/2 x 11 on smooth 65lb. natural white paper. *Riso or Risograph is a printing process made by layering different colored inks to create rich and vibrant images. Because this process requires adding one layer of ink at a time, slight differences in registration are natural and sometimes roller marks from the machine can occur. This is just a quirk of working on the Riso that makes each print unique! I always inspect each Riso print for good print registration and send them with care in a stay-flat mailer. I currently ship out once per week, please allow for 1-2 weeks shipping time. Thank you! All prints are shipped in a cellophane sleeve and a stay-flat mailer.
