I got problem with printing paper bags (100gsm paper). I printed some before with simple artwork / Print. Everything turned out well. Now I am trying to print artwork with larger ink coverage area, approx 22cm round circle.
I got very basic printer without vac attachment.
Problem I have that the print area sticks randomly to the screen when pulling screen up and as a result the print is partly bubbly. I have tried to leave some space between product and screen, printed different speeds and angles but still get unacceptable results. My printing plate is exact width of the bag and I slide the bag over, it prevents the movement to some extent but is not the ideal fix. I am heading to shop tomorrow to buy some spray to make the bag stick to the printing plate. If anyone has any experiences or ideas please share. Thanks!
