Most parts of Australia have experienced some extreme heat over the past month or two.  Nothing nicer than hanging out in blissfully cool air-conditioning when you just can’t get to the beach.  You need to take that same stance with your DTG printer but keeping it cool (but not too cool!) is just one part of the successful equation.

When we turn on the a/c, humidity levels tend to drop as most air-conditioning not only cools the air but sucks the moisture out of it too.  It doesn’t take long for the humidity levels to quickly drop and humidity levels below 35% can really start to cause problems with your DTG machine. Get into the 20% and lower and you’re asking for serious printer issues.

It really doesn’t take much to help keep you and your DTG printer happy during these hot summer months. First you will want to pick up a temperature/humidity gauge similar to the one in the picture in this article. They are relatively inexpensive and help give you the tools to know what is going on with your DTG printing room. They typically show the temperature and humidity levels.

If you are not sure what humidity level you should keep in your printing room, ask your DTG manufacturer. Most will give a level range of say 35%-80% humidity. Typically, you can help ensure a safe humidity level if you try to keep it around 50% humidity.

Unless you have a humidifier function in your air-conditioning (not a common option in Australia), you’ll have to utilize a whole room stand alone humidifier. You can find these at your local small appliance stores (think Good Guys, Harvey Norman etc.) .

The temperature should also be stabilized. Don’t let the temperature in your print room creep up overnight / over the weekend – if it gets too hot, the inks can start to evaporate – and this change in the inks when this happens can cause all sorts of problems in printability.  But don’t go too hard with the air-conditioning – set it for the early to mid 20’s (degrees celcius).  Both your inks and your wallet will thank you.  If you set the thermostat too low, the inks will be less likely to flow as nicely as warm ink and can result in lost nozzles and bad prints – plus you’ll be running the a/c harder than you need to resulting in higher energy bills. The best thing is to try to maintain a constant temperature when you know you’ll be printing or a range of comfortable room temperatures over the summer. Use common sense – if you keep it a constant temperature, you know you’ll always be ready to print.

Keeping an eye on the temperature and humidity levels and making sure they are within recommended levels will take one variable out of the printing mix this summer – allowing you to focus on printing some awesome summer tees!

Shipping Info

Please note that Couriers Please and Aramex collect the day following the day that booking is made. Most other courier options require booking before 11am for same day collection.

We cannot ship to PO boxes using courier services. Please select one of the Australia Post (Express Post or Parcel Post) options if you wish to ship to a PO Box.

How Quickly will I Receive my order?

We do our best to pack your order ready for shipping on the same (business) day once payment has been accepted. This is subject to stock availability, public holidays and weekends. Due to courier booking cut-off times, orders with a Courier shipping option received after 10am on any business day will generally be dispatched the following business day.

Orders for Couriers Please or Aramex shipping will be packed & booked on the same business day as the order is received (or next business day if received out of hours), however these carriers will not collect the parcel(s) until the business day following the booking day.  Please factor this in when evaluating transit times.

Express Post or Regular Parcel Post shipping orders received by 2pm will generally be dispatched same (business) day.

Courier options (eg Couriers Please, Startrack, TNT etc) are generally a 1-2 day service to most capital cities and major regional locations within Australia, however shipments to more minor regional areas will require additional transit time.

Which Shipping Service should I Choose?

You will be able to select from various shipping options during Checkout (before you finalise your order).

Please ensure you refer to the freight calculator to understand the cost for delivery to your postcode at Checkout.

Courier services denoted with ATL are “authority to leave” services – which means that if you select one of these shipping methods, you elect to have goods left without signature, and you accept liability of your purchased items being left at your delivery address door. It’s recommended that you consider where you will be during business hours, to ensure you put down a relevant delivery address if you have selected a Courier option. For example, if you are working, we recommend you have your order delivered to work where you can sign for receipt of delivery.

NOTE: we cannot ship to PO boxes using courier services. Please select one of the Australia Post (Express Post or Parcel Post) options if you wish to ship to a PO Box.

Parcel Post and Express Post services are provided by Australia Post.

Courier services denoted as B2B are for delivery to a Commercial address ONLY.  Even if you conduct a business from your home or another residential address, this is NOT considered to be a Commercial address by the shipping companies, and additional charges may apply if you select this type of service incorrectly.

What if I Don't Receive my Order?

We do our absolute best to ensure that your goods are delivered to you as quickly as possible, but sometimes things do go wrong and the couriers might let us down. We hope you understand that once the goods have been collected by the couriers or lodged with the Post Office, we have no control over the parcel’s trip to you. We will, of course, help with tracking and follow up with the courier company if needed.

Of course, should it become evident after full investigation that the parcel is lost with little hope of recovery, we will replace the order.
