hey guys I'm Claire from BELLA+CANVAS in today's video we are going to cover
everything you need to know about dye migration we'll talk about what it is
what we do at Bella Canvas to prevent it during our fabric dyeing process and
tips for avoiding it when screen printing I'm Shane Snodgrass with stoked on
printing and dye migration is definitely an issue that screen printers deal with
often so today we'll show you some tips on how to mitigate that the dye
migration is where a garment has heated up too much during the curing
process it's allowed the ink to become a gaseous state and some of the dye is
actually coming up into the ink changing the pigmentation of it the way you would
spot dye migration on a shirt is if you are looking at for example we'll say a
red t-shirt you printed white ink on it and either immediately or by the time
you've received your your shirts it's turned pink
so you're gonna see some of that red dye that has come up into the ink the
quality of the t-shirts essential to what happens with the dye migration
process so we see on more obviously on synthetic fibers if there are
inconsistencies within batches that's where you can see even more migration
happening even within a single brand or line whenever printing Bella canvas we
really haven't had many problems with dye migration I think that's a lot due
to the fact that they're centralized dyeing and just really consistency
within run so something that that we print maybe six months ago when we go to
print today we really can depend on that quality and that consistency a Bella
canvas we minimize the chance of dye migration by standardizing the high
quality dyes we use and the machines used in the dyeing process if dye
migration does occur there are certain troubleshooting methods you can try
during the print process to help identify what is causing it
so the first step to mitigate dye migration is definitely going to be on
press you're going to be controlling your palette temperatures very critical
as well as understanding your flash times if you're running your production
you want to make sure that things are getting too hot and you're maintaining a
consistent temperature throughout the production run you really want to
understand your inks and you want to know what is the correct ink for the
garment that you're going to be using I'm using a low bleed or a polyester ink
are typically common on synthetic fibers that you know are going to bleed and
they help to mitigate that risk depending on what ink you're going to
use whether it be a traditional plastisol or maybe a water base or a or
aloe cure low bleed ink every one of them is gonna have a different flash
temperature as well as a different curing temperature so understanding or
knowing what that temperature is might may be anywhere from 260 to 300 degrees
typically you want to maintain that temperature not going to high on the
synthetic fibers because the hotter you go it's going to allow it to have more
of a chance to migrate another tip I have suggest is making sure that your
drive is correctly profiled sometimes you can have hot spots or cold spots
within a dryer so using a doughnut probe is definitely needed to be able to make
sure that your dryer has a consistent heat throughout its run and you want to
make sure that your ink is not being overcooked and it's just being cured to
the exact temperature that it needs to be to fully cure offset you're stacking
when they're coming out of your dryer typically you'll see a lot of people
they'll stack these into a printers dozen or and then go directly into the
box where you're retaining all that heat in the box and over time if you go and
you ship that out the box can even retain some of that heat in the middle
where your customer might receive those shirts and they're gonna say your white
ink is now pink on these red shirts what what happened even though as soon as
you've seen it as soon as it's come off the dryer it was white so it can happen
over time just based on retaining that heat within the box
have you seen dye migration on your garments before what is your experience
been like preventing it let us know your take in the common
