Use a dryer bin to quickly outgas prints produced with solvent-based ink

Like so much in life, quality print takes time – but there’s no reason why it should take longer than it needs to. When using solvent-based ink, before use the print will need time for the solvents in the ink to escape in a process known as ‘outgassing’. 

 

Of course, you’ll want to outgas your prints as quickly as possible so you can move on to the next job and keep those profits rolling in, but what’s the best way to do this? Many print professionals will hang their prints from a rack, or leave them lying on a table, or they might even have a clothes line running through their print room. This option works just fine but if you’re limited in space, it’s not ideal to fill it with drying prints.

 

Here’s where you could really do with a dryer bin. This is simply a large box in which you can store loosely rolled prints as they outgas.

 

There are a couple of things to remember when you’re using a dryer bin:

 

1. Keep your prints rolled as loosely as possible and try to keep space between the rolls – this lets the air flow over the entire printed area and speeds up the outgassing process.

 

2. The gasses released are heavier than air, so they will drop towards the floor. As such, the base of the box will need to have air holes or you could add some form of mesh to the base. You’ll also need to keep the unit off the floor by a few inches to allow the gasses to escape. 

 

If you really want to be efficient, you can also add an extractor fan to the base of your dryer bin, or a blower to the top, which will increase the air flow and dry your prints faster.
