Soon it will start warming up in Canada and that means that some regions of the country will have to deal with high humidity challenges. It can be a nuisance in a number of ways but not least of all when sublimation printing.
If you have perfectly good prints that begin to show colour shifts and fuzzy images during the day when nothing else has changed, increasing humidity might be the problem. If it’s over 50% it’s at the stage where the moisture in the air is going to start affecting your prints.
The solution is to store your substrates (fabric or rigid) and transfer paper in a cool dry place at least 24 hours before using them. Fabrics may have to be pre-heated to get rid of excess moisture.
Thanks to Roland for alerting us to this issue.
