How do you apply an image onto basically any product you want?
It has to be full color, it needs to last ...and it has to be real
fast. You don't want to deal with messy inks, and can't afford to set up
screens, and you only need ONE printed, or possibly bulk quantities, ...or
somewhere in between.
And it has to be profitable.
The answer is simple and has become the standard for quick, high
definition, high quality, low cost imprinting of a vast range of materials.
The solution is
Heat Transfer Press Technology
Geo Knight & Co is the premier manufacturer and
supplier of heat transfer press machines. We specialize in both commercial
grade manual heat transfer presses as well as industrial large format
automatic equipment.
We
accommodate our customers with exactly the machinery they need to transfer
press graphics and other embellishments onto a wide variety of materials.
We manufacture according to the highest industry standards and only implement
solid casting and steel structural frame designs, coupled with state of
the art controls and heaters.
Our
presses have been the backbone of literally thousands upon thousands of
business over the past 4 decades, providing a reliable workhorse of a
product that stands up to the demands of imprinting business, manufacturing
and personal use.
What is the purpose of a heat press?
A
heat press is the machine that presses a transfer onto an imprintable
substrate. Using high temperatures and heavy pressures for a certain amount
of time, the transfer is permanently embedded into the product.
Heat
presses are recommended for professional and satisfying results simply
because standard laminating devices and home hand irons can not get even
near the temperatures required for a reliable transfer. Standard transfers
require anywhere from 375° to 425° F demand serious force in pressing
often from 40-80 psi. These temperatures and pressures are simply not
possible with other heated devices.

A transfer is made up of a carrier paper and inks. When heated
to a certain temperature and pressed with a significant amount of pressure
for a certain amount of time, the transfer inks are passed over to the imprintable
material. Some inks are adhered and embedded to the surface of the material,
while others (namely, sublimation) permeate the coating of the material.
Transfers can be heat
pressed onto fabrics (both natural and synthetic) using standard plastisol
supplier transfers, color copier, or thermal wax & ink-jet computer
transfer paper. Heat transfers can also be printed onto mugs, plates, tiles,
mousepads, ceramics, metals, glass and wood. For these substrates, sublimation
transfers are used. The important factor when heat pressing with sublimation
transfers onto non-natural fabric substrates is to be sure the material
has the proper polyester synthetic coating, as well as a UV coating if protection
from the sun and other rays is an issue. For this reason it is best to get
the materials pre-coated from a supplier. |

The three most common types of image transfers produced are Computer
transfers, Color copier transfers, and what we refer
to as "Supplier" transfers (either screen printed onto carrier
paper or printed via off-set press with transfer inks). Computer transfers
have become very popular over the past few years because of high quality
printers, excellent transfer papers & inks and low cost hardware. The
most common computer generated transfers are:
Ink Jet Transfers.
There are 2 major types
of transfers produced with ink jet printers. The first is a wax based transfer
paper used in tandem with plain ink-jet ink cartridges. The second is sublimation
ink-jet cartridges used in tandem with plain ink-jet paper. With the first
type, the ink-jet wax based "T-Shirt transfer paper" is passed through the
ink-jet printer and then placed onto a fabric-based item and heat pressed.
These papers will work with almost all ink jet printers but not with
laser-jet. Ink-jet transfers are semi- translucent, so the fabric color
will show through the design. This is why it is recommended to only use
light colored garments or fabrics with these transfers (as well as thermal
wax & color copier transfers mentioned below). The second type of ink-jet
transfers produced by sublimation ink-jet cartridges for making sublimation
transfers are currently only available for certain Epson ink-jet printers.
They have however proven to be one of the highest quality methods of making
custom sublimation transfers with near off-set quality and strength.
Thermal Wax /
Dye Sublimation printer transfers.
The most common of these
particular printers are the Fargo Primera Pro and Seiko Colorpoint series.
They print in a thermal wax mode that, when used with their own transfer
paper, create fabric transfers. These printers also print in sublimation
mode, which would produce sublimation transfers. These printers are generally
more expensive and have slower print times, especially for sublimation transfers.
The trade off is simply that the sublimation prints are extremely high resolution
and continuous tone.
Color copier
transfers
Color copier transfers
are produced using a special color copier transfer paper. After copying
the image onto the paper, it is simply heat pressed to the material. This
medium is successful for fabric based items. Standard color copier transfers
will not act like sublimation transfers, or apply onto the same type of
items sublimation works with. There is however a glazing, or post-curing
/ baking process that works with a specialty paper that helps color copy
transfers stay applied to items such as mugs without being easily scraped
off. There is also a special paper available for paper memo cubes which
allows the cubes to be fanned (not stuck to one another) after heat pressing
with a patented cube press.
Supplier Transfers
Supplier transfers are
those that are pre-printed by a transfer supplier either by screening or
offset press in designs shown by catalog or made by special order. The plastisol
/ hot-peel transfers from these companies are generally opaque, and therefore
good for heat transferring onto dark items.
Miscellaneous
Other types of transfers
include embroidered appliqués, die cut lettering, and flock transfers. Embroidered
appliqués usually come as an embroidered patch with heat activated adhesive
on the underside. Die cut lettering is a vinyl or other type of material
that is precut in various numbers, letters, and custom shapes. The user
lays the letters & numbers down on the garment and heat presses them.
This is commonly how sports apparel is imprinted with names & numbers.

The three main ingredients in heat transfer printing images onto
various materials are the Heat Press, the Transfer and the substrate to
be printed.
In closing, one challenge you will face is whether to produce the
transfers in-house or to have them out-sourced by a supplier. If the target
market is a one unit, custom item market, then the transfers should definitely
be produced in-house for controlled turn-around time as well as cost.
Dye-Sublimation / Thermal Wax printers will produce pretty much everything
needed for an expansive custom imprinted product line. Many bubble-jet
and ink-jet color printers accept T-shirt transfer paper (good for any
fabric-based item) but can not produce dye-sublimation transfers unless
utilizing the sublimation ink cartridges (well recommended) mentioned
earlier. If the job in mind is for large, bulk quantities (300 and up)
a transfer supplier should be considered for fast turn-around time and
cost reasons. Transfer suppliers can produce high quality plastisol (hot
peel or cold peel), sublimation and woven labels in short periods of time
with a much smaller cost per transfer than dye sublimation printers, color
copiers, or other small printers. Remember that non-porous items usually
need to be coated with a synthetic polyester based coating in order to
accept the sublimation dyes, unless the material is already synthetic
such as certain plastics.
The only other consideration is whether your product can be printed
with a typical flat heat press or requires a specially shaped platen or
base. Some products are simply not conducive to heat transfer printing due
to their exceptionally odd shape. Again, feel free to contact us with any
questions or requests for special projects. We would be pleased to provide
