~ How to clean the screen version ~
How should I clean the screen plate after printing?
A cleaning solvent is applied to the cloth to wipe off the ink adhering to the plate.
Have you ever experienced ink remaining in the mesh even though you intended to wipe it off?

If the mesh is clogged, the print will be faint and defective.
Once a plate is clogged, no matter how hard you wash it, it will not return to its original state, and will have to be remade.
When the plate looks like this in the first printing, the person in charge is quite shocked.
Then why do you fail to clean the plate?

This is related to the solvent contained in the ink and the cleaning solvent.
The ink contains a resin as a binder and a solvent,
The solvent used is one that easily dissolves the binder resin.

The solvent used is one that easily dissolves the binder resin.
On the other hand, the cleaning solvent does not necessarily dissolve the binder resin well.
In addition, there are many solvents that dry quickly in consideration of workability.

If the cleaning solvent dissolves the binder resin of the ink used well, there is no problem.
Otherwise, it may evaporate by embracing only the solvent of the ink.
When this happens, only the binder resin remains on the mesh and cannot be removed anymore.
Hardened binder resin cannot be dissolved so easily.

I have experienced many such failures.
There was a time when I failed to clean an expensive stainless steel mesh plate and suffered a lot.
Based on this experience, I have considered various cleaning methods.

Let's talk about the points of cleaning the screen plate.
First wash off the ink.
Use a solvent with a high boiling point (that does not dry easily) to wash away the ink remaining on the mesh of the plate.
The point at this time is to keep the ink from drying.
If you use a thinner-type cleaning solvent, it will dry quickly, and the ink will also dry at the same time.
Propylene glycol monomethyl ether acetate (PGMAC) is a solvent that does not dry easily.
A glycol ether solvent with a boiling point of 146°C.

When you wash the plate with this, the remaining ink is washed away with this solvent.
Finish with a quick-drying solvent wipe.
After cleaning with PGMAC, etc., the solvent remaining on the screen plate will not dry.
So, finish with a quick-drying cleaning solvent.
The cleaning solvent used is commercially available for screen printing.

The cleaning solvent used is commercially available for screen printing.
If you wipe the finish with this, it will embrace and evaporate the solvent that is difficult to dry such as PGMAC,
The plate dries faster.
The plate dries faster.
If you wash the plate with this procedure, you can wash it quite cleanly, so please try it once.
