Printing Solutions: Categories of Ink Used in Printing
Printing is really a process whereby text and pictures are reproduced on various materials.
There are numerous printing methods and based on the printing method several types of inks are
employed. Inks utilised in printing might be classified into 4 different categories for example
aqueous, liquid, paste and powder.
Paste is usually applied to
offset printing and there are various kinds of paste inks such as cold set, heat set and energy
curable ones. Many of the different energy curable sorts are electron beam curable and
ultraviolet curable. While energy curable provides the finest quality print, heat sets are most
frequently used. Energy curable ones also require special equipment that makes it one of the
most expensive categories of inks used for offset printing.
Heat set one requires heat
to set it and then it's cooled rapidly mainly because it catalyses the curing process. In cold
set inks, it can be set utilizing the phenomenon of absorption in the stocks which are
non-coated. Cold set ones are often useful for printing books, newspapers, insert printing and
they are the least expensive option if you're on a tight budget.
Solvent ink comprises a combination of organic chemical substances and chemical
toxins. These components have high vapour pressure and colour in this type of ink is achieved
through pigments which makes them resistance against fading. Solvent inks enable you to print
on uncoated vinyl substrates and they are affordable. Banners, billboards, graphics and decals
are typically printed using solvent ink. Is generally considerably using solvent ink for
printing is the prints are UV resistant and waterproof even so the disadvantage in applying
this will be the disposal of the solvent and the vapour made by the solvent.
Aqueous inks are primarily used for desktop inkjet printers. These comprise a
combination of pigments or dyes, glycol and water. Aqueous provide vivid as well as a number of
colour options the only disadvantage of this ink would it be isn't waterproof and could be
washed out of the surface without lamination or specialized coating to guard some of it.
Aqueous inks are also inexpensive to fabricate.
UV curable inks:
inks have acrylic monomers in conjunction with an initiator package. After the printing job is
completed the printed material is exposed to strong UV light which cures the ink. Is generally
considerably this ink is that it dries quickly and the disadvantage is they are incredibly
They're many of the various kinds of inks used in commercial printing
