YMCK Series
– Frequently Asked Questions
What is YMCK Ink?
YMCK ink is an ultra-fine, highly pigmented underglaze ink designed for smooth, precise ceramic decoration. Made with 5000-mesh fine pigments, it flows beautifully from an underglaze pen, allowing for fine lines, detailed illustrations and expressive writing with a single dip. Ideal for use on bisque with a pen, or applied by brush to greenware. Available in a range of vibrant colours and suitable for a wide variety of ceramic styles.
How do I prepare the ink before use?
The bottle contains two stainless steel mixing balls.
Before use:
-
Store the bottle upside down where appropriate to help keep the contents ready for use.
-
Make sure the mixing balls are moving freely.
-
Shake thoroughly before use.
-
Fully dip the applicator into the ink.
-
Gently scrape off excess ink before beginning your work.
Can I practise before using it on ceramics?
Yes — and we recommend it.
Practise on paper first to become familiar with the ink flow, applicator angle and pressure before working on your ceramic piece.
How should I hold the applicator?
The angle of the applicator affects ink flow.
Avoid pressing excessively. Allow the ink to flow naturally and adjust the angle to achieve the desired line.
​Can I use YMCK Ink on greenware?
For brush application, YMCK Ink can be used on suitable greenware surfaces.
For pen-style or fine-line application, bisque is generally recommended, as it provides a firmer surface and reduces the chance of damaging delicate greenware.
How do I clean the applicator?
Clean the applicator promptly after use.
A damp sponge can be used to remove residual ceramic material and help prevent the applicator from becoming blocked.
Why are some dark colours harder to remove from bisque?
Strong or dark ceramic pigments can sometimes stain the porous bisque surface.
If correction is required, light sanding may help remove residual colour. Always take appropriate precautions when sanding ceramic materials and avoid inhaling dust.
Can I apply clear glaze over YMCK Ink?
Yes. A compatible clear glaze can be applied over the fired or appropriately prepared decoration, depending on your process.
We recommend testing your chosen clay, ink, glaze and firing combination first.
