1. Self-adhesive
is easy to stain on the back when printing on the whole page. This is due to
the poor ink absorption of coated paper on the surface of the self-adhesive
label. When sticking
printing, try to use the original ink instead of 6# mixing oil, and add
some appropriately. Adhesive, anti-sticking agent; do not add dry oil when the
weather is hot, the back of the printed page is often easy to get dirty on the
back, and dusting is often used to solve it, although the printing
anti-sticking dust spray contains pure vegetable materials, dispersibility and
The fluidity is good, but the use of powder spray will directly affect the
surface gloss of the printed product, make the ink color not bright, and
pollute the environment, and also affect the accuracy of the offset press.
2. Pay attention to
the balance of offset printing water and ink, and control the water size of the
printing plate. Use the minimum amount of water on the printing plate without
dirtying the printing plate. The sticker is smooth and smooth. When printing on
the solid surface, you must print dark colors first, and the amount of ink
printed is sufficient, and the back is not sticky, and then Overprint the
background color thinly, so that the printed product will have a better finish.
3. To overcome the
disadvantages of large water and large ink in offset printing, the ink can not
be adjusted too thin, too thin, and the back is easy to stain. If it is too
thin, some new ink can be added to enhance the ink viscosity.
