Ironing block print on fabric is primarily done to set the ink, making your designs permanent and washable. This process involves using heat to bond the ink to the fibers of the fabric.
Why Iron Block Print? Setting the Ink
Once you've created a beautiful block print design on fabric, the ink needs to be properly set to ensure its longevity. Simply letting it dry isn't enough, especially if the fabric will be washed. The heat from an iron acts as a catalyst, permanently curing the ink and preventing it from washing out or fading quickly.
According to printing guidelines, once the ink is completely dry, use an iron to set your designs in place permanently.
Step-by-Step Guide to Ironing Block Print
Setting your block print ink with an iron is a straightforward process. Follow these steps for best results:
- Ensure Ink is Fully Dry: Before you begin ironing, make absolutely sure that the ink on your fabric is completely dry. Depending on the ink type and humidity, this could take anywhere from 24 hours to several days. Rushing this step can smudge or ruin your print.
- Prepare Your Iron: Heat your iron to the highest heat setting your fabric will tolerate. Check your fabric's care label if unsure. Cotton and linen can usually handle high heat, while synthetics may require lower settings.
- Prepare for Ironing: You will need two clean press cloths. These can be thin cotton fabric pieces or even parchment paper. The press cloths prevent the ink from potentially transferring to your iron or ironing board and also distribute the heat evenly.
- Create the Sandwich: Lay one press cloth on your ironing board. Place your printed fabric on top of it, with the printed side facing up. Lay the second press cloth over the printed fabric. Your printed fabric should now be sandwiched between the two press cloths.
- Iron the Design: Firmly press the hot iron onto the sandwiched fabric. Iron each section of your printed area for 3-5 minutes per side. This means if you are ironing a shirt, you would iron the front for 3-5 minutes and then flip it over (keeping it sandwiched) and iron the back for 3-5 minutes. The key is consistent heat and pressure over the printed area for the recommended time.
- Allow to Cool: Once finished, carefully remove the press cloths and let the fabric cool completely before moving or washing it.
