I was hoping to get anyones opinion on what went wrong here. I had a client who asked me to print a small run of posters for them. I'm pretty new to screen printing in general and I am definitely not set up for posters but I figured if I take it slow, I could pull it off. Unfortunately the client was not completely satisfied with their posters and would like me to do a small run of reprints for their personal collection. There are some small streaks of color in what should be one flat pantone color running through some of the heavily saturated areas of the print. Can anyone tell me what these streaks are. My gut says that I had one too many PBR's while printing that night but it also says that maybe I didn't mix the ink well enough when trying to achieve my pantone colors. I am using Matsui waterbased inks. This was my first time trying to mix inks to achieve a pantone color. I was mixing the ink by hand with a spatula in a container.
Can anyone comment on what might have gone wrong? I can send you pics if you would like to see what happened or feel free to ask for more info if you would like. Thanks for your time. Much appreciated.
