Heat Press For Cups – Everything you Need To Know
Heat press transfer machine is among the list of options available for those looking for a way to imr9tj on a cup. The beauty of this method is that it supports a wide variety of cups.
Heat press for cups involves using a process known as dye sublimation to successfully transfer a highly vivid, top-quality print on to your favorite cup.
The fact that this method is economical (for lower quantity productions), excellent choice for full-color designs, and for beginners, makes it even more amazing.
Let’s look at some relevant information you need to know about heat press for cups (including how it works)…
An Overview of Heat Press For Cups (The Dye Sublimation Process)
First things first: dye sublimation requires the specially coated ceramic mugs. This coating must feature a high percentage polyester coating. It must be capable of withstanding up to 400 degrees Fahrenheit for longer periods.
Now, the transfer sheets used to transfer the image to be printed onto the cup are printed on using the digital inkjet printer. Among other things, this printer is recommended due to its compatibility with the inks being used.
The inks used with dye sublimation comprises of organic dyes which are easily absorbed by the surface of your cup when heated and turned into gas form.
The transfers are printed in mirror format to ensure they appear correctly when you finally transfer them onto your cup.
The speed of production with dye sublimation typically depends on the type of press. The production can range from 6-8 minutes for every cup. A serious of heat presses helps boost the efficiency of this process to mild productions.
This is dependent on the number you wish to use, how fast you’re applying the transfers and other factors.
Follow These Steps For A Successful Heat Press For Cups
Designing and printing
The creative step for heat pressing cups is similar to that of t-shirts. You’ll need to create a graphic that you wish to decorate your cup with and then print it on the right transfer paper.
Ensure you send a mirror version of your artwork to your transfer paper.
For the best results, ensure the surface of your cup is dust-free and clean. The dye usually experiences some problems trying to penetrate the dust particles. So you could end up with some unprimed spots if you don’t clean your cup surface before working on it.
Trim, Tape, and Wrap It!
Before you apply your transfer to the cup, we advise you to trim it such that the paper can easily fit in the optimal print zone. It will be an excellent idea if you leave 1/8-3/16-inch unprinted border and the top and ¼-3/8 inches at the base.
Also, ensure your transfer paper does not have any wrinkles. These can make the dye leave undesired streaks on your cup.
To achieve a tighter seal around the top edge of your cup, consider wetting the transfer sheet to “melt” it to your cup surface. This will translate to a crisp transfer with not fuzzy edges.
Once you’ve successfully fitted the printed transfer on your cup, grab some heat resistance tape and secure it tightly to the surface. Eventually, wrap it in a Teflon coat and move on to the next step…
Should you wrap your cup or not?
You might have heard of wraps that help you seal your cup and place in the heat press for sublimation.
Although this might be a cheaper option, it’s not recommended for commercial productions. Typically, a cup wrap takes up to 20 minutes in the heat press for an efficient transfer.
Set your heat press temperature to around 330-400 degrees F and press for around 5 minutes under heavy pressure.
Finally- Peel and Splash
Experts advise you to place your cup in water immediately you remove it from the press and peeled the transfer sheet.
At this point, your cup is extremely hot, and if you allow it to “air cool,” the ink will continue to sublimate. This might lead to blurs at the edges of your imprint which rise upwards from the imprinted area.
Once your cup has cooled, dry it, admire the work of your hands (plus the creativity of your mind), and present it to your customer!
