I have just started doing heat transfers on canvas totes but I'm finding the heat from the press is discoloring it...turning the canvas a brownish color wherever the heat hits...any feedback?

I would say start by adjusting your temp and pressure, if you have scorching then the press temp may be too high. Also make sure you use a teflon sheet as mentioned above. Also note that when pressing items, they do tend to get darker but as they cool, it turns back to the original color.

Grey, why would you have to double the press time (dwell time)? Freddie,When I press totes, I use the instructions for the paper. and use a teflon sheet to protect my tote. They do darken after pressing, but it goes away after sitting awhile. Mike

Just read the date on the post. after posting.

why would you have to double the press time
Because I've found that (I use inkjet transfers exclusively), that too often the heat doesn't fully infuse the transfer to the tote when I use a teflon sheet and totes (maybe because the canvas is thicker than most shirts). Double the press time FROM A T-SHIRT prevents this and the teflon sheet prevents discoloring the tote.

As mentioned, sometimes the browning does fade with after cooling, but when you are doing articles on demand, you don't want to explain to the customer that 'it will look good later.' Sometimes I even MIST the bag before pressing... though I know that really goes against the grain of most folks. I MIST a LOT ... sort of like steam ironing ... seems to makes a really clean bright image on the whatever article I'm working with.

AGAIN ... this is for INKJET transfers.

Thanks to EVERYONE who responded. I am using a larger sheet of Teflon...with a teflon pad inside tote, putting totes in dryer before pressing, using Clearsoft transfer paper for 13 seconds and they are turning out GREAT! Thanks again...everybody.:)

Just curious as to why you are putting them in the dryer? If it is to remove moisture just hit it with the heat press a few seconds before pressing your transfer.

The dryer is actually a good idea! Canvas bags hold a ton of moisture and you need to dry them out as much as possible before you apply anything to them, especially any type of transfer made for light colored surfaces so the moisture doesn’t get trapped between the transfer and the bag.
