Introduction
There are many types of screen printing ink.
Choosing an ink that matches the materials and purposes is a important point in screen printing.
There are broadly two types of screen printing inks:
①Water-based ink
②Oil-based ink
This time, we will introduce ①Water-based ink which is easy to use even for beginners.
Features of water-based ink
Can be used by mixing

Ink can be mixed like paint, allowing you to create your own original colors.
Can be enjoyed in layers

Since the inks are transparent, you can print two colors over each other to create the impression of a third color.

Points for handling RISOAQUA INK
Drying
Ink dries naturally, but when printed T-shirts are washed, the printed areas may fade.
For fabric materials with more than 50% cotton, after the ink dry naturally, heat-setting it with an iron at 150℃ for more than 1 minute will make it more resistant to washing..
*For fixation conditions for different inks, please check RISOAQUA INK specification sheet
How to handle the ink on the screen
If the ink left on the screen dries naturally, it may cause clogging.
Cleaning the printing screen at the appropriate time before it dries, can prevents clogging and increase the number of printable pages.

Opacity*1:
The base color is difficult to see when overprinting on dark colored fabric or with dark colored ink making the ink color appear more vibrant.
Anti bleeding*2:
Bleeding is the phenomenon where the dye from polyester fibers transfers to the ink and caused discoloration during heat setting.
Resistance to dye migration means that this phenomenon is less likely to occur.
For example, if you print white on dark red polyester fabric, the white color becomes slightly pinkish.
Also, if you print black on dark red polyester fbaric, the dye will be transferd and the color
change will not be noticeable.
Therefore, the lighter colored ink will be affected by the dark colored polyester fabric,
and If you use dark ink on the lighter colored polyester fabric, the effect will be less noticeable.
