High Density Printing
High- Density Printing the process
of printing a specially formulated
ink through a very thick stencil to
achieve a raised, glossy smooth
print with very sharp edges.
High density inks allows you to
achieve a three-dimensional effect
with sharp, well defined outlines.
The process is very slow but the
end product is unique.
High Density Printing
This is one of the recent developments in printing which gives thick prints on the surface of garments.
Achieved by either giving more number of coats or by using thickener indirect films used for making the screens.
High Density is a popular special effect that rises straight up off the shirt and has a hard rubbery feel with sharp edges. A High density print has slight glossy finish.

Technique
• HD or High Density Printing utilizes advanced technique from
an experience screen printer to achieve a unique 2D style finish
that is raised from the T-shirt.
• Correct HD printing isn't just building layers upon layers
using normal plastisol ink through a standard coated screen. To
achieve the best result, it all comes down to the screen itself.
• We coat the screen multiple times until we are happy with the
thickness of the outside face of the screen, we then use a
special film that works with this thicker emulsion.
• Once our screen is complete, we mix a specially formulated
HD ink which will slightly raise but still remain sharp. This
process is fairly complex and time consuming but the results
speak for themselves.

The Inks• There are three general types of textile
inks (or pastes, as we referred to them in Printing ):
1. Solvent-based inks (Traditional)
2. Water-based inks
3. Plastisol inks (recommended to use in High density print)
High Density Ink• High Density is a popular special effect ink that when
printed, rises straight up off the shirt and has a hard rubbery feel with sharp edges. A High density print has slight glossy finish.
• Suede is a milky coloured additive that is added to Plastisol. With suede additive you can make any colour of Plastisol have ‘suede’ feel.
• Generally 50% suede additive to your normal Plastisol.Suede is a special effect ink similar to high density ink except with soft leather like feel.[18] Suede ink can be either printed high for a 3-D effect or printed normally for a more subtle felt like feel.
A finished sueade print has a matte finish and is very soft to the
touch.High Density and Suede are clear bases that can be added to
any print color. (example blue-"High Density" grey "Suede"

(example blue-"High Density" grey "Suede"
Suede ink was derived from puff ink. The process for printing is
similar, but suede ink results with with a raised fuzzy nap
reminiscent of suede leather
Suede leather is made from the underside of the skin, primarily
lamb, although goat, pig, calf and deer are commonly used
Plastisol inks
Plastisol inks are widely used in garment printing. They are easy to print, do not dry in the screen, can be very
opaque on dark garments, and will adhere to most textiles. They are composed primarily of two ingredients, PVC resin (a
white powder) and plasticizer (a thick, clear liquid). Plastisol inks have one outstanding characteristic, they must be
heated to dry. They will not dry, or cure, at normal temperatures. For a complete cure, they must reach 290-330º F (143-166º C).
Plastisol inks do not color the fibers like a dye. Instead the ink wraps around the fibers and makes a mechanical bond with the fabric. For this reason, they will not adhere to non-porous substrates such as plastic, metal, and glass.
Health, Safety and Environmental friendly.
• Pantone Approved - Color Matching System : • Plastisol Ink Mixing System is the next
generation of inks for mixing colors. The PIM system contains 10 primary High Opacity colors and uses only 6 Fluorescent. All colors have wet on wet properties. Recipe book is available for creating shades. With the uses of enhancer additives special effects become simple. Whether matching Pantone or a buyer’s special color, this system will make matching simple. PIM System will reduce overall cost. The easy of printing will increase production speeds.
• Application and Substrate: Mixing colors can be printed directly on cotton, cotton/polyester or polyester fabrics.
• Stencil: Direct, Indirect or Capillary Films
NB: When printing on nylon fabric use Long Life Bonding Agent (add 10 to 15% by weight).
High Density Inks work
best with solid, bold
graphic areas such as text
or symbols and logos.
High Density Inks
cannot be used for
halftone images or
graphics with fine detail.
Screen Printing
• A process, where ink is mechanically applied to a substrate with the use of a screen and squeegee.
Mesh count The mesh count is the number of threads per
inch (tpi) used to weave the mesh.
Typical mesh counts for screen printing rangefrom 85 tpi to 355 tpi.
The high mesh counts, have a very small threaddiameter and less open area.
Prints require more fineness should be use finermesh count.

High Density v/s Rubber Puff Printing
High density screen printing at first glance seems to be
some sort of high-quality puff print. Actually, the high
density inks are not puff inks at all. They are a high
viscosity ink designed to easily flow through your
screen mesh while holding a very sharp edge with
durability fasteners towards World Standards.
