Dye sublimation printing is an innovative printing process that is currently popular in the print market.
There are many other printing techniques in use today including the well-established practice of screen printing.
Though screen printing is often common for producing items like personalized t-shirts and apparel,
dye sublimated fabric is opportune for custom banners, flags, trade show displays and pops up banner stands.
Screen printing is a printing process in which a stencil is used, ink is applied to the open areas of the stencil and the ink is transferred to a substrate using a fill blade or squeegee that moves across the press. The ink is forced through the mesh openings onto the item that is being printed.
Screen printing can also be referred to as silkscreen, serigraphy or serigraph printing.
The dye sublimation printing process requires two steps. First, the custom graphics are digitally printed on a transfer paper as a mirror image of the original.
The transfer paper is then inserted into a heat press which sublimates the print, meaning the graphics transfer
from a gas to a solid without passing through a liquid stage, onto a polyester fabric or polymer material.
Screen printing can only produce one color at a time and if the graphic has multiple colors, the colors will be layered over the substrate individually.
With multiple colors, if the stencil isn’t properly aligned the result can be a messy and imprecise printed output.
Since dye sublimation first starts with a digital print, all colors are imprinted at the same time and there is no risk of the inks running or the colors not lining up.
Detailed prints with multiple color profiles are produced at their finest quality with a dye sublimation printing technique.
If too much ink is used in the screen print, inks can run or become splotchy.
However, dye-sublimated prints dry instantly due to the heat press that is used at the very end of the printing process.
In a screen printing process, ink can leak from the previous print and show up on unwanted substrates.
This incident is known as “ghost imaging” and can occur if the tools used aren’t properly cleaned after each use.
Screen printing merely places ink on top of the substrate whereas dye sublimation printing allows inks to permeate the fibers of the material.
A screen printed image may crack in time, unlike a dye sublimated graphic print. To truly saturate the material with ink, dye sublimation is the best printing option.
