- What Are Transfers? Without going into the fancy
technical terms for transfers, let me explain a
bit more about heat transfers.
A heat transfer is
when a logo, design or other kind of artwork is
"copied" and then printed onto a sheet
of heat transfer paper. When it's printed on the
paper, it is printed in reverse (backwards or
mirrored) so when you heat press the transfer to
a garment, it comes out the correct way.
There are 3 kinds
of heat transfers that are most commonly used
today. The first is plastisol
ink
heat transfers. This transfer is screenprinted
using plastisol inks and is applied to most
garments (t-shirts, caps, aprons, towels,
etc...).
When you're using
plastisol heat transfers, you can specify hot
peel or a cold peel transfer. As far as costs are
concerned, if they're one or two ink colors, it's
affordable, but when you get to full color
transfers, then the costs go up. Each piece of
artwork must be color separated and screens made
for each ink color. This could run into hundreds
of dollars .
A Hot Peel transfer
is when you heat press the transfer to a garment,
as soon as you open the heat press, you peel off
the transfer immediately. This leaves a nice
'hand' on the fabric and there is little ink left
on the transfer paper. Most hot peel transfers
are designed for white and light colored fabrics.
A Cold Peel
transfer is made using a different type of
plastisol ink. When you heat press the transfer,
after you open the heat press, you rub the
transfer with a chalkboard erasor to make sure
the entire transfer has adhered to the fabric and
then you let it cool. After the transfer has
cooled, you peel the transfer off the garment.
The "hand" is usually heavy and there
is no ink left on the transfer paper. Cold peel
transfers can be applied to white, light and dark
colored garments. By using cold peel transfers,
the chance of the fabric bleeding is reduced. A
prime example of bleeding would be a white ink
transfer heat pressed onto a red t-shirt. The red
dye would bleed through and the white lettering
would turn pink.
You can get
transfers made using metallic gold and silver
inks, and these can be placed onto black shirts
for dramatic effects.

The
second kind of heat transfer used today are Sublimation
Ink
heat transfers. These types of transfers are made
with a special ink, printed onto paper designed
specifically for sublimation ink transfers. When
printed, the ink colors are very dull. When you
close your heat press to the transfer, the heat
and pressure from the heat press turn the inks
into a vapor (gas) and that vapor is forced into
the fibers of the shirt or the coating on the
hard items (mugs, tiles, etc...). When the heat
press is opened, you simply remove the transfer
from the item and the item is done. Once applied to an item, the
imprinted area has no "hand". As the
heat and pressure from the heat press force the
ink vapors into the fabric, there is no ink or
paper residue left on the item. Once the item has
been imprinted, it won't come off and you can't
feel the design on the fabric or surface.
What makes
sublimation ink heat transfers so popular is the
ease in printing them. Sub transfers can be
printed by letterpress, offset, litho,
mimeograph, copier and inkjet printers. Unlike
plastisol heat transfers, sublimation ink
transfers can be applied to cloth (t-shirts,
jackets, aprons, sweatshirts, caps, etc...) metal
for plaques and signs, ceramic mugs, ceramic
tiles, glass tiles, wood, plastic and more. Using
sublimation transfers, you can print 25 transfers
and place them on 25 different products!
The third kind of
heat transfer used today are the OEM/Pigmented heat transfers that are
printed on inkjet printers.
OEM means Original
Equipment Manufacturers and the preferred
printers are the Epson family of printers. Please
see the Printers Section for more about the Epson
Printers.
The preferred Epson
inks are their new Durabrite inks which are a
pigmented ink. Pigmented inks are more fade
resistant and do not run when washed.
Pigmented heat
transfers are printed using pigmented inks and,
like the Durabrite inks, are fade resistant and
colors do not run when washed. Be warned that not
all pigmented inks carry this same quality.
