I have a manual screen printing desk I would like to print some plastic envelopes; can you advise me as to what equipment I need? The ink type, the frame…indicating perhaps the name of the items.
As far as the type of ink is concerned, it depends on the type of plastic: if it is common pvc, the Serigloss will do (vinyl ink). If it is polypropylene, you need the Seriprop instead. Some envelops are made of "plastics", which have a low-stretch surface, and therefore are unfortunately unprintable, with whatever ink.
If you kindly send us a sample envelope, we will be able to advise you as to which is the most suitable ink.
On top of the suitable ink, you will also need the thinner and the Frames Cleaning Solvent 51, in order to get rid of the ink from the frame at the end of the job.
You will then need a frame stretched with a 90 mesh count per cm to fit the stencil (generally one adds an extra 27 cm compared to the base of the stencil, and the same goes for its height).
If you really want to be self-sufficient with regards to the screen printing equipment, we suggest you add a UV light exposure unit, for the frames engraving
Hi, I would like to know if it is possible to create a correct source of light for the frames’ dry using 6 UV, 40w lamps, and if that is the case, how far do I have to place it and how long for.
I would like to purchase a semi-automatic, flat, screen printing machine; what puzzles me undecided is the fact that you do not see many of them around. I have to screen print some paper shopping bags, what do you think?
For a very high number of bags you will need a line with a cylinder print and automatic load/unload.
