Rubber Woven Bag Printing Machine

Listing ID #753269

We are offering woven bag printing machine.
a flexographic print is made by creating a positive mirrored master
of the required image as a 3d relief in a rubber or polymer material.
flexographic plates can be created with analog and digital platemaking
processes. The image areas are raised above the non image areas on the
rubber or polymer plate. The ink is transferred from the ink roll
which is partially immersed in the ink tank. Then it transfers to the
anilox roll (or meter roll) whose texture holds a specific amount of
ink since it is covered with thousands of small wells or cups that
enable it to meter ink to the printing plate in a uniform thickness
evenly and quickly (the number of cells per linear inch can vary
according to the type of print job and the quality required).[5] to
avoid getting a final product with a smudgy or lumpy look, it must be
ensured that the amount of ink on the printing plate is not excessive.
this is achieved by using a metal scraper, called a doctor blade. The
doctor blade removes excess ink from the anilox roller before inking
the printing plate. The substrate is finally sandwiched between the
plate and the impression cylinder to transfer the image.[6] the sheet
is then fed through a dryer, which allows the inks to dry before
moving on.in the case a uv ink is used, the sheet does not have to be
dried, but is dried from uv rays.
basic parts of the press
unwind and infeed section"- the roll of stock must be held under
control so the web can unwind as needed
printing section- single color station including the fountain, anilox,
plate and impression rolls
drying station- high velocity heated air, specially formulated inks
and an after-dryer can be used
outfeed and rewind section- similar to the unwind segment, keeps web
tension controlled.
