Produce special 3-D, heavy deposit, smooth
matte finish prints.
Prints through thick stencils.
Unique flash time will increase production and speed dwell time in the dryer.
Extremely sharp edges can be produced.
Colors may be created using Pigment Concentrates
or Color Boosters. Standard formulas may need adjusting to create darker
colors.
High Density Base can be used in a variety of
ways. You can mix in a standard plastisol ink color to tint the high
density ink. Because standard plastisol is not super concentrated you
will only tint the high density base, for instance, if you mix blank into HD
base it will turn a dark grey. To mix a true color a pigment concentrate should
be mixed into the high density base. High density base can also be used
with foil, caviar beads, and a variety of other applications.
PRINTING TECHNIQUES Set up the
screens as with any print, making sure there is plenty of free mesh around the
design. Choose the proper squeegee length and stroke distance for the design
dimensions. Select a squeegee of 70-80 durometer. More control can be achieved
using double and triple-ply blades. Angle the squeegee to increase deposit. The
floodbar should be adjusted to provide maximum stencil loading. When the screen
is flooded properly, it will take less effort for the squeegee to transfer the
ink. Use an off contact or peel setting to release ink from the stencil.
Off-contact is a critical adjustment. If it is not high enough, the ink will
not release from the screen. Set the print and flood speed to the slowest
setting; then increase the speed, as the design permits. Apply minimal squeegee
pressure; only enough to transfer the ink. Too much pressure will push the ink
into the fabric. The idea is to lay the ink on the surface. For maximum height,
flash the print and stack on another layer. Depending on the thickness of the
first print, additional prints may require increase in off contact. By layering
the print, image results are better controlled.
Application & Storage
Information
RECOMMENDED FABRICS
100% cotton and some cotton/polyester blends. Pre-print and test all fabrics
for dye migration, ink adhesion, wash fastness and other desired properties
before beginning any production.
INK MODIFIERS Not
Recommended
SCREEN MESH
Ink-deposit thickness will be determined by thread size and stencil thickness.
For most heavy-deposit screens use a mesh count in the 60 to 110 t/in or 24 to
43 t/cm range. Follow manufacturer's recommended tension for mesh used.
EMULSION
Direct/indirect capillary films should be used. For best results choose a
thickness between 200 and 400 microns. Stencil films purchased at required
thickness levels allow for better control of ink deposit. Exposure times should
be calculated for best results.
SQUEEGEE 70-80 Durometer
CURE TEMPERATURE
325F (163C). The efficiency of the oven and length of heat tunnel will
determine oven dwell time. Dwell time should be increased with a thick ink
deposit. Failure to fuse ink properly may cause cracking poor adhesion and poor
wash fastness.CLEAN-UP Mineral Spirits or any environmentally friendly
plastisol screen wash.
STORAGE OF INK Recommend storage at 65F to 90F (18C to 32C). Avoid
storage in direct sunlight. Keep containers well sealed.
