As we all know,
screen printing screen is a combination of frame and screen. The frame is made
of wood or aluminum. The frame structure is not easy to damage and has a long
service life. But the screen is made of polyester or nylon yarn, and then it is
stretched by the dragnet. The external force and the spines will be easily
damaged. In the following, there will be three tips for protecting our silk
screen plate.
First, the damage
of the ink-return knife to screen printing plate; we all know that the
ink-return knife is usually made of aluminium, so we must polish the ink-return
knife smoothly and carefully with fine sandpaper; secondly, the ink-return
knife does not need to touch the screen, there should be a little gap between
the ink-return knife and screen plate, so that the ink can evenly cover the
logo without scratching the screen plate.
Secondly, squeegee
may damage screen printing plate; so the squeegee needs to be replaced or
polished with a special rubber grinder after a period of time. At the same
time, when is used it can cut a bevel on both sides to avoid scraping the
screen with sharp corners. Of course, the longer the service life of squeegee,
the stronger the corrosion resistance.
Third, the logo to
be printed can be sealed with transparent glue or kraft paper around to achieve
the purpose of protecting the screen, of course, this is only for products that
are not particularly demanding for printing, precision products are not
applicable.
